Subject: Ringwood yeast
I agree with Jeff Renner that not all the Ringwood/Pugsley beers
have offensive levels of diacetyl (see:
http://www.hbd.org/hbd/archive/4082.html#4082-16 ).
Middle Ages Brewing (Syracuse, NY) makes a Ringwood/Pugsley beer
they call "Tripel Crown" that has so much diacetyl a single wiff
gives me a headache. In fact, all Middle Ages beers (except those
that are cask-conditioned) have excessive diacetyl. OTOH, the
Ringwood/Pugsley beers of Cooperstown Brewing Co. (Cooperstown,
NY), while unremarkable IMHO, do not have offensive levels of
diacetyl. Gritty McDuff's (Portland, ME) is another
Ringwood/Pugsley brewery and I quite enjoy their beers, which
have low levels of diacetyl. In fact, I never would have guessed
that McDuff's uses the same yeast as Middle Ages.
Cheerio!

AJ asks ....

Answer: Andy Walsh, Jan 1998 !
Andy Walsh asked the same question in 1997 in HBD#2555.
Andy then obtained and used some in Jan 1998 HBD#2611
with a description. (also see #2616 followup)
No flies on the 'jesters AJ - we're 4.7 years too late !
Andy noted that Maturex was made by NovoNordisk and may only prevent, not
remove, diacetyl. AJ adds that the FDA now thinks it's safe enough. But
where to get some ?

Subject: Questions on suggestions for improving beer.
Firstly Hi, I am a relativley inexperienced brewer in Queensland Australia.
Once previously subscribed to the HBD and inexperienced in that I previously
have simply followed the instructions on the kit beer tin.
Please clarify these following points:-
On boiling the wort:
After disolving the contents of the tin in water you boil the whole lot,
then add the make up water, cool (by immersion) and add yeast when it
returns to an acceptable temprature.
Or disolve contents of tin into full volume of water, Boil, Cool, etc?
On aerating:
Aeration during fermentation with an aquarium air pump, presumably without
"Air rock" attached. The air rock would be hard to sanitise by my way of
thinking. Aerate for about 10 mins after fermentation has started to slow?

Subject: Re: "...that dreadful Ringwood yeast."
While I like Ringwood it is not one of my favorites, but I'm partial to
Belgain beer.
The only brew I have made with WY1187 (Ringwood) was a clone of Hobgoblin
Strong Ale from Wychwood Brewery (http://www.wychwood.co.uk/)in England.
I was very plesantly surprised with the finished beer. It was well
appreciated at a BBQ as well.
I plan on brewing it again.
When brewing with 1187/Ringwood, it is necessary to monitor your
fermentation temp closely. I kept mine around 64-66F during all of primary.
I'm going to try for 62-64F this next batch.

Subject: Wort Spraying
Robin mentioned that wort spraying is part of the Yorkshire Square
fermentation system and the Black Sheep Brewery uses this system. That is
correct. Also, Theakston's Brewery, makers of "Old Peculiar", use this
system too. I was fortunate to tour both breweries a few years ago and they
were still using these methods in addition to modern methods. We were
actually taken down right next to a Yorkshire square in Theakston's brewery.
Directly above the square there is no oxygen. One member in the tour was
invited to take a deep breath directly above the square and promptly passed
out for a few seconds. We had to catch him as he fell backwards. I asked
if insects falling in were a concern and they said no since they will not
fly near the squares since they can sense that there is no oxygen present.
By the way, after the tour the few pints of Old Peculiar I had there were
the best I ever tasted, before or since. Both Theakstion's and Black Sheep
Breweries are right near each other. So, if you are ever in the UK and up
Yorkshire way don't miss a stop to tour both of these breweries. You get
close to the action, the tour guides are great and the aromas going on there
are superb. I hope to someday return.

Work can be technical enough. For brewing I like to keep it simple. I
filled my brew pot in 1 gallon increments using a 1 gallon jug. Then using a
nail punch, (flat head not pointed) I tapped in a dimple from the outside in.
I also made sure the dimples lined up underneath the handle so I know where
to look or feel. It's easy, sanitary and always there.
For the glass carboys, similar drill. I filled and marked in 1 gallon
increments using a Sharpie. I then emptied the carboy and scratched a line
into the glass at each gallon mark using a carbide hacksaw blade. The white
scratches are easy to see and feel.
Good luck and Good brewing.

Subject: Good ESB Recipe Anyone?
Bill,
I have made a so called Redhook cline for many years. While I cannot say it
is a dead ringer it is close. i personally do not like the diacetyl levels
in Redhook ESB. It is a love/hate type of brew. However I do like ESB's
and it happens to be my wife's favorite style. My recipe is as follows:
Malt - Target SG = 1.054
90% - 2 Row Pale or Pale Ale - I have used anything from Great Western to
DW-C Pale Ale.
10% Crystal 60 or Hugh Baird light crystal
Hops - IBU's = 35
Additions at 75 minutes, 15, and 1 to end of boil.
I use 50% tettanger and 50% homegrown fuggles or willamette from the store
for each addition. For an 11gallon batch, as defined by the volume filling
a secondary fermenter, I use about 1 ounces of each hop at the one and 15
minute additions.
Yeast - My favorite is Wyeast 1968 or White Labs English Ale and second
White Labs WLP029. These produce some diacetyl, but not to the extent of
Redhook. They actually crash their beer to keep diacetyl in. Even though I
live 4 miles from Redhook I have never used their yeast. By the way cask
ESB is outstanding. Much less diacetyl.
Water - Here in Seattle the water has 20 ppm Ca and I add 0.5 grams of CaSO4
per gallon of sparge water.
I am not picky about ferment temp, but the lower the temp the cleaner the
beer.
Cheers,

Subject: Re: "...that dreadful Ringwood yeast."
I've had some wonderful beers made with Ringwood yeast...and many that I've
hated. For the beers that I hated, there are two primary flavors which just
don't work well together: diacetyl and a woodiness/mustiness that I
perceived. So why are some of these beers good and others bad (JMHO)? I
believe it's as much the fermentation process as the yeast itself. Most of
the beers that I found objectionable were brewed on Peter Austin systems
where Ringwood is the house yeast. The open fermenters and recirculation of
the wort may cause this yeast to throw more and consume less diacetyl. I
know one West Coast brewery that uses Ringwood and it uses a closed
fermentation system with totally different results. Perhaps it's not the
yeast alone but how it's used as well that causes some of us to hate these
results?

Subject: Diacetyle removal....
A.J. writes:
"Speaking of diacetyl there is an article in the latest MBAA quarterly
that talks about the enzyme alpha acetolactate decarboxylase which, as
the name implies, decarboxylates (non oxidatively) acetolactate to
acetoin thus bypassing the oxidative decarboxylation to diacetyl and
subsequent reduction to acetoin (by yeast). The idea is to eliminate the
diacetyl rest and krausening steps in maturing beer thus saving time and
money. The enzyme is sold as "Maturex L" and is now FDA approved for use
in the US. Who will be the first homebrewer to try this out?"
This was first (as far as I can tell) mentioned on HBD by Andy Walsh in
November 1997 when he writes:
"Has anyone used Maturex L from Novo Nordisk Ltd to eliminate diacetyl? Is
this available to homebrewers anywhere? If so, what were the results like?
Or is this cheating? Andy. PS. This is an enzyme treatment (acetolactate
decarboxylase) that directly transforms acetolactate to acetoin, eliminating
diacetyl from the process. It is said to reduce beer maturation time by the
manufacturers."
So Andy did you ever obtain this enzyme and try it? Does Nova Nordisk
provide this in homebrewer quantities?

Subject: Dubbel Fermentation
I have a dubbel that I've brewed and currently have it in primary
fermentation. It's a 5 gal. batch with a 5 lbs. two-row grain bill, 4
lbs. Munton's amber extract and 1 lbs of Dark Belgian Candy. I pitched a
Wyeast Trappist strain. The fermentation was fairly slow to start, which
I chalked up to a low temp. (approx. 64-68), but has been going fairly
steady for nearly 3 weeks. It didn't really reach a furious fermentation
(high krausen), but continues to bubble at once every 10-15 sec. My
questions is: is this common for a dubbel? How much longer should I let
it ferment? Should I raise lower the temp? What would the results be if
i ended the fermentation prematurely, or if I let it ferment too long?
Also, since it's in primary for so much longer than i expected, should I
go with a lengthy secondary or short secondary? Thanks in advance Sean

Subject: CASCADE DRY HOPPING
I have dry hopped cascade for years and never been really satisfied with the
results. I tried making a hop tea by boiling .5 quart of water and adding 1
ounce of cascade pellets. This tea is allowed to steep for 5 minutes in a
closed pot. The hops are strained out and the tea added to the beer at
kegging. Without a doubt this gives me the best hop aroma and flavor of any
technique I've tried.

This is will be the last reminder that there will be homebrew competition on
November 23rd, 9am-12ish, at the Split Rock Resort in the Poconos of
Pennsylvania in conjunction with their annual Micro Brew Festival. Contrary
to the web information, judging will only be on Saturday. Entry fees, $5,
will go to the Multiple Sclerosis charity. This is a sanctioned competition
and will use the standard BJCP/AHA style guidelines judging all beer, mead
and cider styles. Entries should be shipped to The Resort at Split Rock,
One Lake Drive, Lake Harmony, PA 18624, Attention Stacey Gould, for receipt
by November 20th. Somehow I had this date wrong previously. Two brown or
green bottles with no markings are required. Any standard entry forms
identifying the brewer and the appropriate entry category/subcategory are
acceptable. Any standard homebrew competition entry and bottle
identification forms are acceptable.
Judges and Stewards will be needed and they should contact Stacey Gould
[spevents@ptd.net] or me to secure a position. Judges and Stewards can hand
carry their entries if they pre-register with payment. Checks should be
made out to The Resort At Split Rock. Judges will receive an entry to the
beer festival or entry to the beer dinner for their efforts and need to
indicate which they wish when they commit to participate. The BOS winner
will receive a complementary weekend for two at next year's Split Rock Beer
Fest as well. But just entering makes you a winner for helping a good
cause. More information will be available at the Split Rock web site

Based on the very good answers I have already seen to your request, you
should already have concluded that there is no "correct " answer to your
question. EVERY action (or inaction) in the process WILL impact the
finished product.
That does not mean to say that there is no answer to your question at all.
The answer depends on the current level of your brewing skills, the true
meaning of your stated goal ("to brew a great beer"), and how far you are
willing to go to achieve that goal ("effort required"). "Great beer" has
a different meaning from one person to the next. It is YOUR definition
of "great beer" and "minimum effort" that matter the most --- not mine,
and not that of other brewers.
My interpretation of your question may be a little different than that of
others. I am going back to the basics. Brewing follows the old 80-20
rule, which I will word like this --- 80% of your goal can be achieved by
controlling 20% of the variables. These are the basics that must be
achieved before it is worthwhile to look further:
#1) Sanitation: If you do not maintain an adequate level of sanitation,
you do not need to worry about your ingredients, your brewing process, or
your equipment.
#2) Quality of ingredients: You cannot make a "great beer" (regardless as
to how you define this) if you do not use great ingredients.
#3) Sanitation: Great ingredients will be dumped down the drain if you do
not maintain an adequate level of sanitation.
#4) Recipe: You cannot make a "great beer" if you do not combine those
great ingredients in the proper proportions, in the proper balance, using
proper procedures.
#5) Sanitation: This really cannot be over-emphasized, although one can
become paranoid about it. All it takes is one infected batch, and you
will never overlook this factor again. OTOH, "great beer" was made for
hundreds of years before anyone knew what sanitation even meant.
#6) Patience: Take your time formulating that perfect recipe, and then
acquire those quality ingredients to match. Do not make up a recipe just
to match what you have on hand, and be mindful when making substitutions
because an ingredient you need is not available at your LHBS. Do not
rush the brewing; do not rush the fermentation; do not rush the
conditioning. The most important single ingredient in "great beer" is
time (but like all other ingredients, TOO much of it can be detrimental).
#7) Sanitation: Did I mention sanitation as being important?
I suspect that most brewers quickly get to the point where these basics
are so routine that they do not even think about them any more. Once
these basic variables are securely under your control, you are within 80%
of your goal. It then makes sense to look at other factors.
Most of these factors have already been mentioned by others. They are
such items as full volume boil, hot break removal, rapid cooling,
oxygenating the wort, adequate pitching rate, controlling the
fermentation temperature, trub removal, preventing oxygenation after
fermentation, proper conditioning levels, and so on. Taking charge of
these variables can get you 80% closer to your goal, achieving 96% (the
original 80% plus 80% of the remaining 20%).
If you want to get even closer to your definition of "a great beer", then
you have to address more obscure and/or technical factors. Study the
technical journals, perform experiments, and take charge of even more of
the factors that influence the flavor and character of your beer.
Or is a 96% success rate "good enough". Only you can decide when you have
reached your goal.

Subject: Ranking Improvements, ringwood
I look at brewing like this, if you invest all your time and effort in
getting perfect yeast. you can screw up alot of other things and still have
great beer. Just look at the plethora of mediocre brewpubs we have in the
USA...
That being said. If your a beginner and your striving to be a better brewer
then you need to get one thing straight. DOCUMENT EVERYTHING!!! Let the
anal-retentive side out of its box and write everything down. Write down
what you want to do, before hand. and write down what you did, as your
doing it. Sure, you can learn by making the same mistakes over and over and
figuring it out on your own. but there is nothing like reading something
new and being able to look back at what you did to see if that might have
been a factor.
1. Document everything. Recipes, Proceedures, then brew and record what you
do as you go, time's, temps, f)*#@&kups...
2. Massive quantities of healthy yeasts (this includes yeast starters,
proper airation/oxygenation, and proper nutritional suppliments) Note: I
did not say liquid over dry yeast. Dry yeast is easier to get perfect, it's
just your # of choices that suffers.
3. Sanitization, Sanitization, Sanitization you can't really get enough of
it. (biggest error of veteran brewers--we get lazy)
4. Wort chiller, if you don't have one, you need one--unless you live on
one of the Poles
5. Full size brew kettle 8g for a 5 g batch, 15g+ for a 10 g batch. your
boil should be really rolling, if the swells are not +/- 1" your not
boiling hard enough
6. Fermentation temperature control
7. Fresh ingredients, fresh hops, fresh malt, fresh extract--it all
matters!!!
ps. similar list to My good buddy Mark Tumarkin, but i prioritized
mine...after all, brewing is a Priority ;<)
- --------------
Ringwood
Is a great yeast IF you treat it well. Most brewies don't--and their beer
suffers. Basically, all their beers taste the same. If you abuse this yeast
it really asserts its character into the flavor of the beer. If you treat
it right, you can't tell what strain of yeast your using. To me ringwood is
as simple as that. If I can mildly pick it up in a pale ale or mild, OK, i
don't mind it. If i taste it in a stout--yuck!

Subject: Beer improvement \ diacetyl \ Redhook
I think most of the responses to the difficult
question about what is the easiest thing our fellow
HBD'er can do to make the greatest improvement in his
beer have been right on the money.
The comment I liked best, however, was from Mark
Tumarkin who Suggests a strict regimen of inquiry
-quaffing a lot of beer and paying attention to
details.
you must be able to define beer flavor profiles that
You enjoy, and to understand the factors that
contribute to these profiles. Beer appreciation, IMHO,
is by far the most important factor in brewing better
beers. You can build yourself the slickest brewery an
amateur has ever seen and have impeccable sanitation,
enthusiastic, well-coached, well-fed yeast, and make
beer after beer that you don't like. And if you don't
know what you don't like, or what you do,
brewing enjoyable beers will be a matter of luck.
Unfortunately, what we're talking about here takes
many years and many batches, and is NEVER complete.
Nevertheless, it should be a top priority.
I've never used the Ringwood yeast, but I have to get
a kick out of discussion around diacetyl (or VDKs
which includes 2,3-pentanedione as Steve A has tried
so hard to educate us on). It is my perception that
the fear of VDKs seems to stem from two main sources.
First and formeost, it is an upredictable compound in
filtered, pasteurized, or otherwise poorly handled
beer, which is obviously the dominant form of
packaging and distribution. No brewer wants to sell a
raunchy beer, and since, unlike cask conditioned ales,
the brewer has no control what happens to the beer
once it leaves the brewery, it is very risky to send
beer out the door high in VDKs.
Even if VDKs were stable in the finished product, I
would imagine that people are perceptive to VDKs at
drastically varying thresholds, and that appreciation
of them will vary at all these thresholds. Thus, for
breweries with profit motive as #1 consideration, it
makes the best business sense to eliminate it, thus
reaching the maximum amount of consumers possible. We
are not mere consumers; however, we are brewers who
control our own drinking destiny. In that sense, VDKs
are not defects any more than any other flavor can be
considered a defect if its presence is inappropriate
for the style.
I appear to be mildly perceptive to VDKs, but love
what they do for a beer. The key for me seems to be
that it should balance well with other flavors, and
not dominate. It appears to accentuate malt, creating
a nice toffee character, and blend with hops,
seemingly contributing a more citrusy character.
"Getting in touch" with VDKs has added a whole new
dimension to my own brews.
This info might help Bill Sample who asks about
Redhook. A mild diacetyl character mixed with some
fruity esters is how I would characterize Redhook's
unique profile. Others might disagree, but the most
significant factors here might be yeast and
fermentation. Hops and malt could be simply viewed as
providing the correct color, bitterness levels.

Subject: Cocoa Beans
Abe--
While I have not used coca beans, I have used milled cocoa in beer with much
success. If I did have access to cocoa beans, my first inclination would be
to mill them with the rest of the grist, mash, sprage and boil just like
normal. I would treat it just like any other strong-flavored specialty
grain (e.g., roasted barley). If making a stout, I would add .5 - 1 pounds.
I use that because my one experience using chocolate was in a stout. I
added 2.3 oz of strongly flavored bakers cocoa (Penzy's) directly to the
boil. The finished was excellent IMO, with a distinct chocolate aroma and
flavor. Good luck and keep us posted on how it turns out. BTW, I believe
that Brew Your Own had an article on brewing with chocolate somewhat
recently (last year maybe). Hope this helps.

Subject: Measuring liquid volume in brewing vessels
There have been a lot of good suggestions for solving this problem, but
what the heck, I'll stick in my 2 cents. I use a very simple device made
from a piece of bare copper electric wire. Functionally, it is the
equivalent of a ruler or dipstick, but it costs nothing (assuming usual
access to odds and ends), and it can stay in place throughout the brewing
process. Also, it can be calibrated in increments as small as you choose,
depending on how much effort you want to put into making it.
To make this measuring device, start with a wire about twice as long
as the vessel is deep. Bend one end of the wire into a hook so it can hang
inside the vessel from the lip, and curve the excess wire to the side just
before it hits the bottom of the vessel. This is a just temporary bend to
keep the wire from running into the bottom, and you will remove it
later. Now fill the vessel to capacity with a known amount of water (10
gallons, for example). Grab the wire with needle-nose pliers at the point
where it just enters the water, and bend it to the right at a 90-degree
angle. The bent portion will now be parallel to the surface of the water,
and just touching it. This is the full-capacity marker bend. About a
half-inch farther on from this marker, bend the wire again so it is once
more hanging down toward the bottom of the vessel. Now remove one
increment of water (say one gallon), and make another 90-degree bend where
the wire just enters the water, only this time, bend the wire to the
left. Continue this process, each time removing one increment of water and
making a new marker bend with the directions of the bends alternating right
and left until you have marked off as many levels as you choose. As you
go, relocate the temporary bend as needed to make marker bends at the
appropriate places, and to keep any excess wire from getting in the
way. When you have made as many marker bends as you need, leave a little
tail hanging down, and cut off any excess wire. You will end up with a
shape that goes down, right, down, left, down, right, down, left, and so
on. This thing can be hung inside your boil pot and left there throughout
the boil, making it very easy to monitor the starting volume, ending volume
and boil-off rate. When you're done, just shine it up with a scrubby, and
put it away until the next time. If you do different size batches, as I
occasionally do, make two gauges. I do mostly 10-gallon batches, so the
one I usually use has bends to mark 13, 12, 11 and 10 gallons. But I also
made another gauge for five gallon batches that has bends at 7, 6 and 5
gallons. These gauges are durable, effective and cheap.

Subject: Oxygenation
In HBD 4081, Dave Clark asks whether it matters when wort is oxygenated,
before or after pitching. This is not my area of expertise, but I find it
really hard to believe it could matter. After all, we're only talking
about a difference of a minute or so in timing. And the amount of yeast
added can't affect the specific gravity enough to significantly alter the
absorption rate.
But I would like to suggest that you use the Oxygen for your starters
as well as your main wort. It helps grow a good crop of healthy starter
yeast, which gets the main fermentation off to a good start. I've been
very pleased with the results since I started doing this.
