Yeast Questions
I am interested in yeast "ranching". I've been reading archives issues of
HBD about the culturing and freezing of yeast samples. I have a few
questions
regarding information that I've come across.
1. What should the specific gravity of the "base" wort be?
I've read 1.040, but I also believe that I've read 1.020.
2. What recipe should be used for the wort?
Again I've read 2 Tablespoons of DME in a cup of boiling water.
What about hops?
3. I am also interested in how streaking for isolated colonies reduces or
eliminates mutations?
4. Does anyone know of a good book on yeast propagation the is in-depth and
accurate,
yet is semi-easy to read? I am especially interested in storing and
quality control.
Thanks!

Subject: pitching rates and dumb beer
Hi all,
Troy writes:
"This discussion about lowering your pitching rates for better beer has
really piqued my interest. This tears down *every* piece of information I
have ever read regarding this topic."
Back to me:
This isn't really a discussion; it's two guys (Burley and the
self-proclaimed "Dr. Pivo") claiming something that brewing scientists and
commercial brewers long ago proved false.
Troy says:
"As Dave B says, "yeast growth with the associated by-products are an
important part of beer's flavor. Pitching larger quantities of yeast in
fact
"dumbs down" the impact of the yeast growth on beer flavor." I take that to
mean, short lag times, ie. little yeast growth, means a "dumber" beer as
Dave and Dr. Pivo are saying."
Back to me:
Whoa! Yes, yeast growth by-products are important to beer flavor, but you
need not abuse your ferment by under-pitching, etc. to get yeast growth!
The yeast will grow in brewer's wort regardless of the amount you pitch.
The key is to not over-grow the yeast and thus yield an obnoxiously high
level of fusel alcohols, etc. The "dumbing down" of beer character is
achieved by using very high levels of tasteless adjuncts (rice and corn -
yes, I consider corn to be relatively tasteless in beer) and the use of
miniscule quantities of old hops (A-B ages their hops for 3 years before
they consider them "ripe"). A-B's Budweiser has a distinctive yeast
character despite it's "commercial" pitching rate. It's the rice that makes
it relatively bland.
Troy then says:
"Dave also says, " I think the middle ground is an important place to
consider..."
I was wondering if he (or anyone) would be willing to give a middle ground
lag time for homebrewers to shoot for. Assuming excellent sanitization ,
what is a reasonable lag time that would allow for enough yeast growth to
realize the benefits in flavor?"
Back to me:
There is no simple answer to this. Every yeast strain is different, and
every beer style requires different flavor profiles provided by the yeast.
In my opinion, Bavarian Weizen yeasts make the best beer when underpitched
(by commercial lager standards). At my brewery I pitch the Weizen with
about 3 million cells per mL, which is about 4 times less than the commonly
quoted bland pilsner pitching rate. If you go much lower than this, I find
that the beer will become solventy tasting. I guess there are some that
would consider solvent a flavor attribute, but most (including myself)
consider it a defect.
Understand that Weizen yeast (and many other bold strains like Belgian
types) are NOT good examples of typical yeast performance. The flavors that
most beers will acquire from yeast abuse (i.e., underpitching) are NOT
pleasant to most people. If you like the solvent flavor of ethtyl acetate
or the heady, harsh character of fusel alcohols, by all means underpitch
your wort. Most people do not like these flavors, though.
A "full-flavored" beer will express its fullness in malt, hops and balanced
yeast by-products that result from a healthy fermentation. Messing with
your yeast (underpitching and/or underoxygenating) will yield unpredictable
and often unpalatable results. You most certainly cannot expect to harvest
and repitch yeast from such a fermentation.
This is really a pointless argument. Countless commercial brewers and
brewing scientists have demonstrated the results of "proper" fermentation
management. If a couple of homebrewers, whose beer most (none?) of us have
ever tasted, wish to question these well-tried practices, that is fine. Be
aware that these guys are in the minority, though, and unless you taste
their beers and find them acceptable, question their assertions.
My beer is commercially available for all to taste, if you come to Albany or
to the monthly meeting of the Malted Barley Appreciation Society in
Brooklyn, NY. Draw your own conclusions.
Have fun!

Subject: continuous O2 and honey post
About the use of honey which I originally commented
upon a few days
ago, I
do think that the use of 2 lbs of honey in a 5 gallon
batch could be
reason
for a slightly long ferment, although inadequate yeast
at pitching may
also
be the trouble. My thinking is along the lines, that
using 2lbs (which
should contribute about 85 gravity points or so to a 5
gallon batch),
<snip>
I'd just thought I'd add my two cents worth. I went
through my notes, and found that I added 2 lbs of
honey to my honey apple wheat ale (the original Mad
Dwarf), and my OG was .070. This was in conjunction
with 6.5 lbs M+F wheat extract and 2 12 oz cans of
apple juice concentrate.
Like I said, just my 2 cents worth.

Subject: skunky beer
Well, now that the Baron of Burradoo has been ousted by the local
constituency and has sought refuge with the Baron of the Southern
Highlands, he has finally come clean on the skunk scent story.
Yes, it is true that when Phil posted here on the HBD that skunks didn't
exist in Oz and that he'd never smelled the aftermath of a skunk, I
emailed him privately and offered to send him some hunting scent. I had
to wait until hunting season got closer before beginning the search, and
then ended up mail ordering the stuff from Michigan.
It arrived with the Postman visibly upset, soon upsetting the secretary
and both of my business partners. The bottle apparently had leaked. I
put on some rubber gloves and took it to the main sink in the washroom
to open the package. Surprisingly, the bottle had neither leaked nor
broken.
I rewrapped the bottle in bubblewrap, wrapped that in a kitchen trash
bag (rolled and folded to provide multiple layers), and then sealed the
little bundle in three Ziplock bags.
The rest is history. Phil has been debaroned and the local postal
supervisor isn't any too pleased with him. But now he knows what a
skunk smells like. And as for returning the bottle, I'd rather that you
didn't. I'd suggest that you dig a hole about 2 meters deep, lay in
some plastic, gently set the bottle on the plastic, and then fill the
hole with cement. Post warning signs.
As for the comparison of skunk and Eric Fouch's brew that I was allowed
to sample, I never made any such comparison. All I said was that his
pumpkin ale didn't have any chunks in it. He has paraphrased me
correctly in other parts of his post, though.
Now, let's have a brew.

I would only like to append it by saying that you do this
"side-by-side", that is, with the exact same wort so you are truly
controlling your variables. It is only you who knows what you like, and
by doing it in a controlled manner you'll find out if it is really the
thing that you think made a difference, or if you are just getting to be
a better brewer in an infinite number of ways, and assigning this
success to the wrong part of the process.
As to Alan Meeker's thoughts and questions, I do believe he is soon to
matriculate from the Dave Burley school of "If you stay in school long
enough, you'll probably irritate the pants off of somebody, and they'll
give you a degree just to be able to stop having you around".
been there, and promoted and sent those lads along their way.... sure
does make it a lot more peaceful around the office.
I don't think you "get it" Alan, and I don't think you are going to.
But you will probably always be right.
PS: This is really not my fault. I don't really give a stink about how
poor the beer is in the US, and how assured they are that they all live
in brewing heaven..... Phil made me write this stuff... he thought the
self serving Yanks needed a stirring up, and held a virtual roasted
wombat and a tail-less cat pointed at my head until I sat at the
keyboard. Jill stood behind him and encouraged him the whole time: "Give
to 'em Phil! Give it to 'em!" ... I promise. She's been cheesed at me
ever since the HBD dive trip from Port Douglas fell through: "That's it
folks, just climb aboard.... no, no need to take your passports along,
it just makes everything too easy when they start asking questions
later, when the boat returns to port empty."
That and the threat of more mpegs of sausage stuffing ani (surely that
must be the plural form of anus?), and the decision was made.
signing off with the only comment I consider appropriate.

Subject: No Blues With Eric
Let me diffuse a growing misconception.
Eric and I have had no falling out. We always argue like this.
We are in love. (this is Jill speaking)
I would like to thank Steve Lacey for his discussion on the Eastern Long
Necked tortoise/turtle/terrapin.
To any Australian brewer who has not smelt a skunk, I can concur with Steve
that it does indeed smell similar to a frightened chelodina longicolis. It's
not from their urine though Steve, they excrete it from glands as a defense
mechanism, much as I expect the skunk does.
But getting back to the subject matter. Doc Pivo contributes some
interesting thoughts on pitching rates (which he promised us some time ago
he would do) and I think he is right.
Not because I know.
Not because I can scientifically prove it.
Not because I happen to be a reptile keeper.
Doc Pivo is suggesting that all you have read is not necessarily gospel.
That there are a huge number of variables out there that have not been
proven either way.
Doc Pivo challenges the American way of making beer.
The Americ(k)an way of life.
And all this because at a party he was forced by Eric to try one of his
dreadful pumpkin lagers!
I don't blame the man for being disgusted!

I can only assume that these discussions relate to pitching the
sediment/slurry from 1.5 gallons and not pitching the whole 1.5 gallons.
A couple of days ago I racked a lager from the primary and then poured
off about 1200 ml. I gave 250 ml. to another club member and then
pitched just under 1 litre into another 23 liter lager which then took
off like a freight train. The other brewer reported his fermentation
started quickly also. I would have liked to compare the difference
between 250 ml. slurry and 1000 ml. slurry.
- ---
Should I assume that when people talk about stepping up a starter that
they are (for example) pitching 50ml smack pack into 500 ml, and
pitching 150 ml slurry from the 500 ml into 2 liters or are people
taking all of the first 500 ml and adding that to 1.5 litres of starter
to make the second stage...
- ---
Yeast starters seems to be pretty basic stuff but I often find these
'basic' topics are discussed in fragments leaving a new/relatively new
brewer like myself unsure/confused/or worse about the actual procedure.
Is anyone actually pitching 1.5 gal of yeast starter into a 5/6 gallon
batch?

Subject: Awful outcome of filtering hot water
Hello all,
Just a quick follow up to the "hot or cold water through the
carbon filter" thread. I was warned that activated carbon tends to
give off all of the accumulated crud it's adsorbed when heated above
100F or so, but not until after I had made 11 gallons of strong bitter
using water from my household hot water tank run through the filter.
Last night I finally worked up the courage to sample the batch. What
a shame: perfect clarity, some nice malt, hop and fruity notes, totally
overwhelmed by an odor that I can best describe as being like sniffing
a bowl of dust. The taste was exactly what the aroma promised: there's
a good bitter hiding under a horrible dusty/chemical flavor that coats
the tongue alamingly. Ah well, at least it's an imaginative way to
lose a batch. Certainly much more creative than just a pediococcus
infection, eh?
So, don't (repeat DON'T) ever run hot water through a carbon
filter! Just thinking about that flavor might put me off beer for a
while.

2-4 hour lags are the middle ground, even when pitching wort onto a yeast
cake already in the fermenter. Try, as I have for a lager, pitching a 1
liter of yeast slurry meant for a 1 bbl ( 31gals) commercial starter into
10gals of wort. I got a 20min. lag to the first bubble out the air lock. The
beer was a Bohemian Pilsener and was very clean and crisp, but with little
yeast character at all.
I still think it is hard to over pitch on the home brew level, but you may
find pitching rate like the above would "dumb down" a Belgium-style ale as
very few esters would be produced if the yeast ran out of fermentables in a
generation or two. Just another data point.

As well, those of you with auto-sparges, how do you control the water

Subject: Not all Yeast are Created Equal
A lot of discussion about pitching rates been going on. One thing to
remember is that all yeast are not created equal! The idea that a
starter is a starter is a started, adn it is the VOLUME of starter
that indicates the quantity of yeast is just not true. the other
thing that a lot of people assume is that the health of the yeast is
also a constant. What brewers need to remember is that the health of
yeast may vary, one may have a high number of very stressed out yeast,
pitch them into well oxygenated wort with lots of free amino nitrogen,
phosphorous, calcium etc, and build up the health of the yeast in the
wort, which ferments out well, or one could get a really marginal
quantity of very healthy yeast and pitch into wort with poor
oxygenation etc and they will be very stressed by the time they
ferment out the beer. Another example would be the brewer that stirs,
and incrememtaly feeds and oxygenates a 500mL starter made with high
wuality wort with yest nutrient, and another that pitches a wyeast
pack into 500ml of malt extract, doesn't give it oxygen, or over
oxygenates the starter without feeding it. These different methods of
starter production would, in my opinion, produce very different yeast
populations, maybe different numbers of yeast cells, maybe not, but
certainly the ability of the yeast to adapt to a given wort, and
ferment it out in a desireable and predictable way would be very
different. Add to that a difference in wort quality, oxygen level and
temperature at pitching, and there are too many variables to even
think about. what does all this mean? It means that there are very
few absolutes in this area, it all depends..... Oh yeah, except the
comment that was made aobut yeast "growth' and fusel alcohols, I
agree, higher yeast growth means higher fusels.

This in particular makes me wonder. There are considerations that are
overlooked in the dogmatism in this discussion. For example, if one
wants to make a highly-attenuated beer, a higher pitching rate will
ferment more completely. If one wants to make an estery beer, a lower
pitching rate can be a good thing. (All of this assumes a pitching rate
in which yeast has to multiply ten times or LESS.)
Autolysis is a bigger danger with high pitching rates, especially if one
is pitching dead yeast cells. Fusel alcohol production is a bigger
danger with lowe pitching rates especially at higher fermentation
temperatures. Getting a judicious balance between yeast growth and
adequate active yeast is probably the key for most brewing situations.

From: mikey@swampgas.com (The Artist Formerly Known As Kap'n Salty)
Subject: The Pivo Regime
As much as enjoy Dr. Pivo, my own experience tends to dicate high
pitching rates. I saw the quality of my lagers rise when I took to:
1) Slowly cooling my starters to lager pitching temps (48F or lower in
my case).
2) Doing much larger starters (slurry from 1.5-2 gallon starters in 6
gallons). This tends in my case to work out to about 35-40x10e6
cells/ml. I may also pitch on the yeast cake from a recent primary.
Advantages (in my case) included better flavor, no stuck or
underattenuated ferments -- a problem I used to have regularly-- and
the ability to be a good bit less anal about sanitiation (during
primary fermentation, at least). I believe Dr. Pivo mentions the
latter.
I am beginning to suspect that I can also pretty much dispense with
step 1 with no ill effects, and just crash cool the large starter.
As for ales, I really have no idea 'cause I don't brew them -- I
believe it was DeClerk who opined, "Generally speaking, ales are for
little girls", but I could be wrong...
On the other hand, I would be interested in the good Dr.'s exact
procedure for brewing with undersized starters (starter quantities,
ferment temps -- general fermentation regime) as I'm willing to try
anything at least once, provided it doesn't involve feces and sharp
objects.

to get it to a walk-in cooler. You were all very helpful. I was overly
concerned with oxidation because I wasn't factoring in that the atmosphere
in the carboy would be carbon dioxide. the tips on not breaking the carboy
are helpful too.
One other quick question (because I screwed up last night). I bottle my
brew, rather than keg (personal preference as well as not having the will to
purchase the equipment). I have a wonderful porter I wish to enter in a
competition. Due to some poor planning and enthusiastic consumption, I only
have some 680 ml bottles left - which obviously are too big for a
competition. I wanted to "rebottle" the beer into standard bottle sizes, but
without losing carbonation (natural, not forced, carbonation). I thought I
had my bases covered (had everything a refridgeration temperatures, a
planned siphon to prevent splashing or agitation, etc.)
However, clearly I didn't have my bases covered. I made a huge mess, and may
have messed up a few bottles of a wonderful beer. Is there a better way to
rebottle beer without making a mess, losing precious liquid and killing
carbonation?

Subject: Bacteria and yeast
I would like to add (if I may be so bold) to an excellent post by
Mr. Lansing concerning stray bacteria possibly being present in
commercially available yeast.
There is a certain amount of bacteria (and lord knows what else)
in just about everything that we eat, drink, or otherwise consume
with our bodies. But is that really a problem? The yeast products
that are offered for sale to the home brewing public are not
guaranteed to be 100 percent bacteria free. I doubt that many
home brewers would be willing to pay the added cost of obtaining
yeast products that are certified or guaranteed to be completely
free of bacteria. (I think Mr. Lansing made this point very well).
The beauty of purchasing something like a live yeast product
is that the performance easy to establish and track. And it
doesn't take a microscope to do it. I think you know what is
coming next. It is the old argument that goes, "I been using this
product (or this practice, or procedure, or whatever) for years
and have never had a problem." Kinda makes your skin crawl
doesn't it? The point is that thousands (perhaps millions. At
the very least, hundreds of thousands) of batches of home
brew have been made with commercially available yeast
products. Most of these batches do not end up contaminated
to a such a degree that would be perceptible to even G. DePiro's
exquisite palate.
Most contamination is a result of bad sanitation practice. A
few problems may attributable to bad QA/QC on the part
of the company that sells the yeast. Ultimately we (the
consumer) are the final QA/QC on these types of products
and I just havent seen a whole lot of people out there that are
claiming that their beer was infected by bad yeast that they
purchased. I think if that was the case, word would get around
and the suppliers of tainted yeast would soon be out of business.
Sooooo, it is an imperfect world that we live in. Get over it.
A guess that's why we have beer.

Subject: Creating "off" flavors in good beer
Hey Folks
I am looking for some information on "off" flavors.
More exactly I am looking for info on what to add to a perfectly good
light beer (used as a base) to cause it to have off flavors such as
DMS, Acetaldehyde, esters, and any others that a brewer might run
into. I have seen this info someplace but just can't remember where.
The reason I want to do this is to educate The Low Country Libations
Home brew club at our next meeting. One member needs this education
dearly. This members seems to pick the "off flavor of the month" and
tag every ones beer with it except his own. My latest Pils got a dose
of it last time I gave him a sample and rather them tell him he is
nuts I decided to educate him as well as the rest of the club (my pils
is fine, every loves it and no one can taste the flavor he tagged it
with except him) I am cutting myself close here as the next meeting is
this monday evening (Feb 21 Ott Ott) so e-mail would be grate
Thanks

Fellow HBDers,
First of all, I should explain that since my departure from the AHA,
I've been at Five Star. Actually, Five Star's chemist and co-owner,
Charlie Talley, was waiting at a local brewpub to buy me a beer and talk
to me about a job the very day I got canned.
I have been reading the HBDs and I want to thank everyone for their
support. Now that Santa brought us a nice computer for Christmas, I
promise to be a more-active participant.
Anyway, two of my main responsibilities at Five Star is to handle their
malt sales (they had just aquired the contract for importing malt from
Malteries Franco-Belges) and re-address the products, prices and sizes
available for homebrewers.
So, without sounding like a commercial, let me try to answer Troy's
questions.
>1. Is this the concentration you use? I notice they sell a two oz pack for
>homebrewers said to clean a 3-5 gal fermenter... that is not the
>concentration that Five Star recommends... what's up with this?
No. The directions on the labels are for commercial use. For
homebrewers we recommend 2 oz. of PBW per 5 gallons of solution. Let me
explain the discrepency. With cleaning and sanitizing chemicals, there
are three main factors, concentration, temperature and length of time of
exposure. Basically, if one of these three factors is decreased for
whatever reason, another must be increased to obtain the desired
effect. Commercial brewers are usually using PBW for CIPing a kettle or
fermenter and the actual exposure time is often reduced. Therefore,
they make it up with a higher concentration.
Other considerations are the amount and type of soil and the cleaning
system. Commercial brewers have spray balls in their CIP systems. If
one hole in the spray ball gets clogged, a blind spot could develope
where the solution doesn't come in contact with a portion of the kettle
or fermenter. The increased concentration breaks down the soils more
rapidly and avoids the clogging.
The homebrew sizes were originally developed as samples for commercial
breweries and still have the original labels. Chemical labels need to
be approved by the FDA and once approved, nothing additional can be
added. However, our homebrew kits have the applicable instructions and
we are about to begin a program of inserting instructions for
homebrewing and other uses for PBW in each jar. I will get better
instructions listed on our website as well.
>2. How long is it good for? Can I soak a keg one night, another keg the next
>and my fermenter the next? Will it last that long and be as effective at
>room temp?
PBW does get "used up" it doesn't last forever. The answer to your
question depends on the amount of soil. However, I have seen 2 oz in 5
gallons clean 5 filthy carboys, one right after the other with each one
soaking about 15 - 20 minutes. Soaking overnight is perfectly alright.
I have found that the rinsibility can be affected when soaking 24 hours
or more. If this happens, just add a little StarSan in your rinse water
and that should take care of any residue.
>3. How do breweries use it in such large quantities without going broke?
Like anything else, when you buy in larger quantities, the price goes
down. At least that's how it usually works.
One point that we identified is that Five Star had homebrew sizes of
products that were reasonably sized and priced if one brewed 2 to 4
times a year and they had brewery sizes and prices for commercial
brewing. The problem is that Five Star didn't have product sizes and
prices that fit the brewing schedules and budgets of brewers like most
of us on this forum.
But, as I've said many times, homebrewers will find a way. Many
homebrewers just bought chemicals from their local commercial brewers or
bought a 50 lb. pail from Five Star and divided it up. Now, I know it's
ridiculous to think that homebrewers will shake in their boots when you
mention that something is illegal. But you do need a license to pack or
repack food-grade chemicals. The real issue is that Five Star could
lose their license if we don't take every precaution to prevent
repacking. This is why homebrew shops can't buy in bulk, repack and
resell chemicals like they can do with malt. (Please don't tell me if
you know some who do.)
What we came up with is what I call, Homebrew Bulk Pricing. It's
basically a bulk purchase that you can still run through a homebrew
shop. While I don't want to get into a commercial about the Five Star
products, I would greatly appreciate any input on the idea of bulk
purchasing through the shops. You can check the details on our website
listed below.
Thanks for your time! Even though I never left, it's great to be back!

Hello!
I've been interested in fermenting via an

ones on the market: the BrewCap and the Fermentap.
Does anyone know the major advantages/disadvantages
of each, and can you recommend one over the other?
Public postings and private email-s are welcome.
Thanks for any information.

Subject: Wyeast invitation
Greetings All!
It's been a while since my last post. An update "Pine Haven Brewing"
has been evicted from "Debbi's kitchen" and now resides in "My Garage"
(except on really bitterly cold winter days when even a 60K-BTU
portable Dragon and my propane fired brewpot can't manage to nudge
the thermometer up a bit, my wife takes pitty and has actually
suggested that I come back into "her" kitchen and use my old split-pot
stove-top method. God bless her!). One advantage of the new location
is that there is space for a lagering fridge (a 1950's vintage Norge with
a Johnson's Controler attached)!
The recent "Dr. Pivo" posting and responses (life getting you down a bit,
the daily digest seem a bit lack-luster, I know just toss a "Dr. Pivo" log
on the fire and watch the flames shoot!) have caused me to examine my
yeast selection and pitching rate practices.
I was very pleased to see Wyeast Labs' David Logsdon post the other day
and am glad to know that they (Wyeast) monitor this forum.
I have used Wyeast products for several years and am a satisfied customer.
I have a request for Mr. Logsdon:
As Wyeast is a major supplier to the Home Brew market place I wonder if
they (Wyeast Lab's) would supply this forum with the following information:
# Your thoughts on the ideal starter size for a pseudo standard
size 5-gal(US) batch of Ale.
# Your thoughts on the ideal starter size for a pseudo standard
size 5-gal(US) batch of Lager (Pils).
# Your suggestion on techniques for stepping up a 50(ml) Smack-Pack
to the appropriate starter volume (using standard Home Brew supplies
, i.e. DME, Growler Jugs, 22oz bottles, yeast nutrients, etc.).
# Any other recomendations or "recipes for success" with regards to
proper handling and useage of your product in the Home Brewery.
As this forum has Home Brewers at all levels of experience perhaps
some of your suggestions could be marked as "newbie hints" or "advanced".
Please note that I am not asking for an "official statement" but only for
informal suggestions to help Home Brewers use your product to it's best
advantage.
I would also extend this same challenge to any and all other yeast supply
companies and|or their representatives who monitor this digest.

Subject: high temperature wort settling
Hello,
There have been some atricles in the past about how break material can be
removed by allowing chilled wort to settle for a few hours in a separate
tank before transfering to a fermenter. The disadvantage of this is a
greater risk of infection. What if I wanted to remove the hot break
only, but have a counter-flow chiller. If I insulate my kettle to try to
minimize convection currents, and allow it to gradually cool to about 180
F, will the hot break settle out? With hot and cold break, are the two
breaks formed at separate discreet temperatures, or does the solubility
limit of break material keep changing as the wort temperature decreases?
If the "hot break" gradually comes out of solution as the temperature
drops, where is the line drawn between hot and cold break?

Subject: Re: Help needed on high SG
OK, thanks to all who responded with help. This is a case where I would
like to give my local homebrew shop a good piece of my mind. When I went in
there I was going to buy their British malt only rather than the Laaglander,
it was the owner that convinced me that I needed it for "a little body".
Then later before I started I had a hunch that replacing some of the
Laaglander with some honey would be good...again I was talked out of it!.
Bah!! Better to follow my beer instincts next time. So this is my plan:
1) After 1 week in the secondary, the SG is basically unchanged at 1.042. I
am going to pitch champagne yeast tomorrow on the very off chance that it
might work. If it doesn't, I figure no harm done as it should just settle
out.
2) I am going to withhold judgement on the hops until it is close to
bottling time. Tasting it tonight the balance seemed slightly improved. It
has a *lot* of very wild ester qualities which are rather interesting
combined with the coriander and cardamom, so I don't want to mask that too
much. It almost reminds me more of a sweet fruit wine than a beer.
3) Having a couple of homebrews first convinced me not to worry so much
about this batch. May be OK.
4) Thanks to the person who suggested blending it with another beer...that
may be what I eventually do. After drinking most of what I had pulled out
for my SG determination tonight (whew! Enough alcohol so that after a while
you don't notice too many nuances of taste!) I poured the rest into a cherry
wheat beer. The resulting brew was *very* tasty. I may end up blending some
of this with something else at bottling time.
I'll keep you all informed of my ongoing experiment. Thanks again.
Rich
