Subject: Long mash, dextrins and mouthfeel
Brewsters
Bret Morrow did an excellent experiment in which he
determined that alpha amylase continued to be active
longer than the typical 90 minute mash. The point is,
any starch or high MW carbohydrates can still be
chopped down in a longer ( like an overnight) mash.
The real questions is what about the beta amylase?
If there is still beta around then these "dextrins" could
be reduced to sugars and fermented. This higher
alcohol content could change the charactrer of the beer
versus one in which the shorter mash time was used.
Bret's experiments confirm the lifetime of alpha
amylase indicated in the literature. As an HBDer
pointed out recently, some years ago AlK and I argued
this point about beta amylase's lifetime at 158F.
Based on the literature and my experience it was
concluded ( if it ever was) that even beta emylase
has a finite lifetime at high mash temperatures.
I mean, if not, why would professional texts list 158F
as being as appropriate mash temperature?.
However, it is a basic principle of mashing that
the shorter lifetime of beta amylase at higher
temperature is what gives rise to the temperature
dependence of the dextrin content of beers.
What then of the lower mash temperatures?
Beta lives longer and can be active for many hours
at these low mash temperatures to produce a
virtually dextrinless beer if carried to extremes.
The worst case would be one in which the mash
was brought to a low saccharification temperature
and then allowed to cool ( ala overnight). Dave Line
at least had a temperature control on his Bruheat.
What is too often ignored when discussing the lifetime
( which is a theoretical number often measured
under non-mash conditions) is that as the mash
temperature goes up, the conversion speed of the
substrate of BOTH ( or should I say all) amylases
increases.
Now, how does this relate to Bret's experiment which
stated purpose was to find out if a long mash
produced a thin beer or not. The presumption
( as I inferred) in his proposal is that fewer HMW dextrins
as a result of long lived alpha would somehow
reduce the body and produce a "thin" beer.
It will come as a surprise to some that the dextrin
content of a beer is NOT what determines the body
or mouth fullness of a beer.
M&BS -p 600, 1ed
"..."body". This ill defined beer property is thought
to be related to the concentration of macromolecules,
principally proteins and melandoins, in the beer.
Dextrins which were implicated earlier are known to
have little effect"
I accept this, however, it also seems that for a given
grist, a low T mash will give higher alcohol content
in the beer and may in high OG beers produce an
"alcoholic" beer which may have some of the
charactertistics of a thin beer. Overnight mashes
of high OG beers may tend in this direction.
- -------------------------------
I agree with Mark Wilson that an overnight mash takes
longer in terms of total time BUT if you work late, don't
have a weekend schedule that permits it and the like
but can devote say from 8pm to 12 pm ( some people
DO take two or more hours to get home after work -
at least in the Northeast) for two nights or such then
you too can brew. It is a compromise, but it can be
done. Better to stay with minimashes and use extracts
IMHO. But most of all just brew.
>I haven't read any of Charlie P.'s books for years so
don't remember much of >his advice.
Most of it wasn't very good, like pouring hot wort through
the air ( see picture), using a carboy for a primary,
short mashes, bad iodine test method ( first ed) and
the like. He did begin the collection of data on brewing
supplies and analyses which had been ignored in earlier
hobby books. Luckily, I learned independently from
professional texts and British hobby books before I
ever read a CP book.
> I'm going on personal experience. i.e., when I
switched from 1hour sac. rests to 15-20 min., similar
recipies did not show much difference in extraction
efficency when using shorter sac. rests; I average around
>75-80% efficiency.
OK. But there are well understood reasons why you
could have gotten the result you like, but not for the
reasons you assume. You still haven't addressed
the major question - milling efficiency. When I
changed over to double milling ( as I have described
in the HBD) my points went to low-mid nineties. I
had been using the longer mash times used by
professionals and still getting low effficiencies,
so mash times is not the only determining factor in
efficiency and therefore your conclusions are not
well founded based on your present data.
Remember that saccharification is not the only thing
that is happening in brewing and it does take longer
to do some reactions than others, especially those
sequential ones. There is a reason the professionals
take longer. If 15 minutes were enough they, of all
people, would use it.
>It's like the no-sparge argument; even if extraction is
less efficient using >a shorter mash, I'm getting
getting better beer in less time.
People are getting better beers with no-sparge because
they are higher OG and have not exracted some of the
phenolic negatives from the grain. The buffers in the mash
control the solubility of these compounds. As the pH rises
as in a "natural" sparge when the soluble content of the mash
is removed, these phenolics are extracted and detract
from the maltiness of the beer. However, pH
control during sparging makes this a non- result, IMHO.
> The reason I started shortening my mash times was
not to save time, but to get more body and mouthfeel
from my beers; less time for the enzymes to break the
sugars into >smaller sugars means more of both.
If your real reason for operating a short mash time is
to get more dextrins, there is a better way and that is
to operate at a higher mash temperature. Try a mash
at 158F and see if you don't like that better.
Mouthfeel is due to the proteins present ( see my above
quote and comments) not the dextrins as some claim,
and you apparently believe. Operating at a high mash
temperature will denature the proteolytic enzymes and
may give you a better mouthfeel. Try it.
>At any rate, sounds like an experiment waiting to happen.
Brew the exact
same beer, same mash temps, different mash duration.
And, I'll try and dig
>up some comparisons in efficiency, etc. from my brew log.
OK, but as I said, efficiency is mainly determined by
the crush. Dextrins by the mash temperature. Soluble
protein content by the maltster and low temperature
holds. I really don't see any reason for anyone else
to do this experiment, but I do suggest you do this for
your own satisfaction as long as you include a high
temperature mash as part of your scheme.
I disagreed with your statement that all books which
had been written on the subject of mash times were
wrong because you made a few good beers with a
short mash time ( remember you said 5 -15 minutes). I still do.

Subject: Hop Oil
Jeremy writes (a long time ago):
>As mentioned, the processed NA beer could be dry hopped, or late hop or dry
>hop essences added (e.g. www.hoptech.com) to replace lost hop aroma
>components.
I bought some HopTech East Kent Goldings Hop Oil a while ago. It was
something like $15 for a little (1/2 oz?) dropper bottle. I immediately
tried it on a decent IPA (which I wanted to dryhop, but didn't have
the time) but couldn't get it to work. First, I tried the recommended
amount... no hop aroma that I could detect. Then I tried double the
recommended amount... still no hop aroma. Finally, I tried four times
the recommended amount... faint hop aroma, but I would not mistake it
for East Kent Goldings (note: I'm a pretty experienced BJCP judge, so
it's not like I don't know hop aroma when I smell it). Then I looked
at the IPA... it had little flocs of whitish material suspended in the
beer! They looked like dead Sea Monkeys(tm)! Even the recommended
amount gave me these flocs.
I was told by the retailer that he kept the oil refrigerated and I
received it via UPS the next day. I too kept it in the fridge until
use (1 day).
So, has anyone had success with these hop oils from HopTech? Did you
get this turbidity also? Did it smell anything like actually dryhopping
the beer? How did the beer do in competition? Did the judges praise
the hop aroma?
I guess it's better than if it looked like *live* Sea Monkeys ;^).

My collection of beer literature doesn't have much to say about percise
alcohol levels of Anheuser Busch products. I spent an hour or so this
weekend trying to track down the Alcohol % of US produced Budwiser. I may
have passed the master brewer exam on the BUD web site, but I didn't come
away with the answer I was looking for. Does anybody else out there know?
Is there a list of known alcohols in commercial examples I did not uncover

Subject: Big Brew '99 recipe
Fellow HBDers,
I have received a few suggestions for improving the extract version of
the Collaborator Milk Stout recipe that we will be using for Big Brew
'99. I am running these recipe versions past those who have already
registered to participate in Big Brew '99, but I would like to get
your input as well.
To refresh everyone's memory, the problem with the original extract
version of the recipe was that we were using 1 3/4 pounds of flaked
grains, oats and barley, without any enzymatic malts. You can still
find the original all grain and the uncorrected extract versions of
this recipe at the Big Brew '99 webpage,
http://www.beertown.org/bigbrew99 .
The dilemma was that for Big Brew, we wanted to have a version of the
recipe for homebrewers at all levels of brewing skill and experience.
The solution/compromise that we've come up with is to provide two
extract versions of this recipe. Here's what we came up with. Please
take a look at these versions and let me know what you think.
(Changes are marked with an asterisk, *.)
Collaborator Milk Stout
==================
We would like to credit Jeff Brinlee, Jeff Langley, and Ken Bietschek
for the original recipe, Widmer Brothers Brewing Company and the
Oregon Brew Crew for the conception and fruition of Collaborator and
Bob McCracken for spearheading this amazing project.
Extract/Partial Mash Version
- ---------------------------------------
Ingredients for 5 U.S. gallons
* 3.5 lbs. Pale Malt Extract
* 2 lb. Pale Malt
1 lb. Wheat Dry Malt Extract (55%)
1.5 lb. Caramel Malt (60L)
* 1 lb. Belgian CaraPils Malt
5 oz. Black Patent
12 oz. Roasted Barley
12 oz. Flaked Oats
1 lb. Flaked Barley
1 lb. Lactose (added to Kettle)
1 oz. Centennial, 10.1% alpha (75 min)
1/2 oz. Willamette, 5.1% alpha (5 min)
With this version, we will explain that a mash is required with the
pale malt, flaked oats and flaked barley.
Extract/Steeped Grains Version
- --------------------------------------------
Ingredients for 5 U.S. gallons
5 lbs. Pale Malt Extract
* 1 lb. Pale Malt
1 lb. Wheat Dry Malt Extract (55%)
1.5 lb. Caramel Malt (60L)
* 1 lb. Belgian CaraPils Malt
* 5 oz. Black Patent
12 oz. Roasted Barley
* 0.5 lb. Flaked Oats
* 0.5 lb. Flaked Barley
1 lb. Lactose (added to Kettle)
1 oz. Centennial, 10.1% alpha (75 min)
1/2 oz. Willamette, 5.1% alpha (5 min)
With this, the steeped-grain version, we will suggest a slow steep
for, at least, the pale malt and flaked grains.
- ---------------------
One of the nice things about Big Brew '99 is that all the participants
have email and we can change things relatively easy. We hope to have
the website updated with the new versions of the recipe by April 15th.
If you have any comments or suggestions, please email them to me as
soon as you can.
Thanks for your help and input! I encourage all of you to participate
in Big Brew '99!

bottles or lose carbonation at some point.
Anyone know how long a keg will retain carbonation

that I wont have to find out since I am sure I
will be drinking more now knowing that the beer I

Subject: Flavor and Serving Temperature
Greetings
I remember someone discussing this earlier this year
but for the life of me, I can't find it in the
archives.... What gives with the flavor/serving
temperature relationship? Why does my beer taste
poorly at fridge temps, like after an overnight stay,
but taste great if only slightly chilled. I don't
think its a 'frozen tastebud' thing either. SOP now
is to take a chilled bottle out of the fridge 15-30
min before drinking to let it warm up. Now I have to
convince friends that my warm beer really does taste
better warm.

Another major incorrect assumption is that the reports in the books are
correct. Most of them are demonstrably wrong. Add up the charges and
calculate the pH required for balance. Often this will be 10 or 11.
Alternatively assume a pH like 8.4 and calculate the charge imbalance.
It is often a couple of milliequivalents/L.

Subject: Re: questions on priming and bottle cappers
Dawn Watkins asked about how much priming sugar to use in bottles of cider.
Well, I never made a cider, but I have primed a 'few' batches of beer and
would recommend that you don't bottle prime, but batch prime instead.
Unfortunately I prime with dried malt extract and I don't recall how much
corn sugar to use, maybe 3/4 cup for 5 gallons? Others will surely jump in
on that if it's wrong, and even if they don't, just look it up in any
homebrew book. You also asked about corn syrup, I don't have a clue if this
is ok to use. you can get corn sugar at a homebrew/wine supply store.
Black beauty capper? I have use it and it works fine.
Your final question was if you can brew less than a 5 gallon batch, yes you
can, but why? The beer will keep a long time if you keep it fairly cool. I
have had beers taste fine after 11 months, unrefrigerated.
Good luck,

Subject: Extra High Extraction Rate
PJ-
One thing to not lose sight of in high gravity brewing/dilution is your hop
rate. Hopefully, you noticed your higher than expected gravity while it was
in the brew pot and hopped accordingly: While diluting to a lower effective
OG is fine, be aware that you are also diluting your bitterness (I wonder if
this would work on my wife?).
From: Dan Cole
spending an additional $50 for one with the spigot, I decided on one
of the weld-free setups. Just drill a hole and use the included
compression fitting and the spigot.
Any advice?
Here in The Craft Corner, we routinely put weld-free side drains in 5 gallon
pots, 15 gallon kegs and 55 gallon drums of K-Y. I just go down to Ace
Hardware and pick up a 3/8" ball valve with 3/8" male flare fittings on either
end. Drill the appropriate sized hole in the side using a step drill
(Unibit). On the inside, I like to use fitting the has a 3/8" female flare to
3/8" male compression. A few washers and a roll of Teflon tape from the Bent
Dick Toolbox, and the bulkhead seals up fine.
From: Steve Gibbs
there any consensus as to good or bad points in having a long mash (ie.
degradation of proteins etc.) or has the addition of a decoction in my
process potentially helped in the problem areas?
Happy Brewing
Steve, I don't think there is much of a problem with doing overnight mashes
(hell, I almost did one myself!), but I think there is a problem with a post
overnight mash decoction: You are sure to have liberated some extra starches
from the decoction, and added them back to a mash where the enzymes have all
pooped out. I doubt many enzymes survived the overnight mash.
Speaking of overnight mashing, I was in the park the other night and....
Sorry, that's all the time Fred has for todays HBD. I've sent out to the back
forty to give the hop shoots a nice Epsom salt soak.

Two thoughts regarding the above news:
Are your going to establish an informal question format for questions to be
answered by the Siebels Staff? I was fortunate to have a tour of the facility
last month by the teaching staff. They were all willing to answer as many
questions as time permitted. For every question that they answered, I had two
more. The HBD queue will certainly be over the 47K limit for quite some time
afterwards.
The 1999 Siebel Course Catalog points out that attendance fell for regularly
scheduled 1998 courses. They suggest that depending on this years (1999)
enrollment, some classes could be eliminated or only offered every second or
third year. I hope that Siebels participation on the HBD can somehow help
them to continue to provide the range of services they have in the past. They
have 127 years of experience teaching brewing technology and some of that
info is shared here on the HBD.

Subject: diacetyl confusion
I think I see where the debate over diacetyl popped up.
In #3000 Dave says,
"Diacetyl in lagers *is* considered a fault as it can be
present in large quantities in lager due to a pediococcus
infection, but it and the pentane dione is normally
present in low quantities ( if the above referenced
table is correct) as I have indicated._Diacetyl should
not be considered a fault in low concentrations._" (emphasis mine)
Probably another reader saw red before he really finished reading the
first
sentence. Perhaps a better wording would have been..."Diacetyl in
lagers_may_
be considered a fault when present due to a pediococcus...."
Even then I would need to ask; is the diacetyl the fault or the
pediococus
infection?
What is a fault anyway? Isn't acetaldehyde a fault? but isn't the
distinctive
character of Mudweiser? then it can't be a "fault", but I wouldn't want
it
in
my CAP. Anything can be considered a fault when out of context and out of
style.
Seven % alcohol in a Berliner Weisse would be a fault, but alcohol is
certainly
not generally considered a fault.
I can see someone jumping to argue the point of "diacetyl in a lager is
a
fault." I hear too many judges whose vocabularies seem to consist of two
words;
"diacetyl" and "phenolics." Stripped of phenolics _most_beers would taste
very
flat and one dimensional, but diacetyl has its' place.
My peave is that in that same mindset, someone thinks diacetyl in a CAP
is
a fault. Lets look at history; lager brewing was in its' infancy at the
turn of
the century. Diacetyl wasn't even a word then. Refrigerated brewing was
also
in its' early stages. Do you really think the brewers would manipulate
their
process to minimize diacetyl production? They didn't even know what it
was.
In a CAP diacetyl is not a defect. This beer has a slight "corn
sweetness"
(not exactly but that is how it is best described) so who here doesn't
butter
their corn to "richen" it a bit? Someone with the "no diacetyl in lagers"
frame of mind insisted the BJCP not allow diacetyl in the CAP
description.
This may also come from the mindset of the "AHA guideliines are all
wrong."
That one being one of the newest is certainly not "wrong." Dr. Fix worked
with Jeff Renner and Peter Garofalo and me to get that one description
correct. Mindset in brewing is a very bad thing, it leads to a
de-evolution
of beer. The big brewer's have successfully managed to remove any
"cloying
maltiness", "lingering bitterness", any "possibly offensive to _someone_"
character from beer. And look where that left us.
I will leave you with a quote from Pierre Celis, "Just when you think
you know all you need to know about brewing, it is time to go back to the
beginning and start shoveling out mash-tuns again."
Oh heck, here's one from me, "Read 3 different books on brewing and
you'll
come up with 6 different opinions."

Subject: Gravity fed real ale.
Has anyone ever toyed around with a corney keg so that the beer can be
drawn by gravity alone?
Some pubs in England serve pints out of kegs which are kept on their side
and the ale is drawn out of a spiget at the lower end of the front side.
Also in England, the homebrew shops sell plastic kegs that are operated by
gravity and adjusted by an adjustable intake for the air to enter into.
Is there any real benefit to this method? I believe that this is method of
serving "Real Ale" and would like to try it myself here in the US of A.
I have the CO2 set up but want to try something new.Any suggestions or
comments will be appreciated either of the discussion

Also, I would like to plug our Grand Opening Party with Michael Jackson.
It's Saturday, May 15. I have commitments from 18 Texas breweries from
all over the state to bring beer--it's free and lasts from 2-8 pm. There
is also a Michael Jackson Tutored Tasting at 3 pm. Tickets are $15 and I
don't have many left but Michael will be around all day to chat and sign
books etc. This is really an event for homebrewers, I have not and will not
advertise it to the general public. Everyone is welcome, well almost
everyone :)
There is also a brewers only reception for Michael on Friday evening. Most
of the Texas brewers are coming but any brewers from outside Texas are
welcome as well. Give me a call or email if you would like to come.

Hi There,
I've been lurking here in the UK for a while and just had to respond to
this.
What is the problem with a 1073 Porter? Whenever I make Porter I aim for
1065 - 1070, which as far as I know is the gravity that this type of beer
used to be made to in the 'good old days'.
I'd say bottle away and enjoy a fine high gravity beer.

Subject: Sanitizing with lactic acid
Out here in So Cal its popular to brew orange blossom pale ale
this time of year. Throw a quarter pound of blossoms in the boil
for 1 minute. Any more than 1 minute and you extract too much
bitterness. (harsh bitterness not a malt sweetness/hop bitterness
type of thing) My goal is to try and dry hop with the blossoms.
This poses hugh sanitation problems. Some questions
1) Would it be possible to sanitize the orange blossoms using a
water/lactic acid solution at room temp with a very low pH?
2) If possible, what pH should I adjust to?
3) Would 1 pint of the water/lactic acid solution override
(I don't know the proper term)
the buffering ability of the already fermented beer? ( 5 gallons)
4) If the above is not possible, is there another way to sanitize
orange blossoms? (besides heat or acid)
Thanks in advance, Mike Rose Riverside, CA

Hello All,
I recently posted a request for information about what equipment you

responses by email and I appreciate each one. I did not realize that so
much of what I have used to make wine with could be used for brewignas
well. I have decided to "put together" my own two stage, glass, brewing
kit. Finding carboys reasonbly priced (I kept seeing prices like $25.00
plus shipping) proved to be a challenge. I have found a distributor of
mexican laboratory glass that will sell direct to me for $12.50 each for
a 6.5 gallon carboy. The catch is that I have to buy 10 of them. I
only need (or want) three. If anyone wants one, email me at
baspivy@softdisk.com and give me your mailing address with ZIP code so
I can estimate shipping costs.
Thanx . . .

Subject: Sanitation and septic systems
I'm sure not everyone brewing has city sewer, whereas you can dump
anything that doesn't rot out or clog your drain pipes. What do the
brewers with septic systems do with their used sanitation fluid of
choice? I go to great extremes to not let my iodophor mix and my
chlorine water go down the drain. Since they are designed to kill off
microbes, which your septic tank depends on, how do other brewers dispose
of their spent liquids? I toss mine on my driveway or where I have
unwanted vegetation, but it doesn't seem to hinder plant growth. All
this siphoning and lugging of buckets is bothersome. Of course, I'm only
looking for serious replies, if that's possible Considering some posts
of late, that may not be a reality. TIA.

There is a common product (here in California) called TSP in big letters in
a cardboard box. It is sold at Home Depot and Von's grocery store AND it is
NOT Tri-Sodium Phosphate. In fact it even says Contains no phospates. The
TSP stands for Totally Superior Product, and it is your average sodium
carbonate cleaner, just like Arm and Hammer Super Washing Soda. I really
don't know if true Na3PO4 is still available.
And contrary to the rumor mill, PBW is sodium PERcarbonate and sodium
metasilicate plus a few other additives. It is much more effective than
sodium percarbonate alone. By the way, these are cleaners, not sanitizers.
Five Star, the maker of PBW, has a web page at http://www.FivestarAF.com

It is - it just depends on _where_ you are. Phosphates have been banned in
many states as a major pollutant on inland waterways due, particularly, to
phosphated laundry detergents. I can still buy it here in MI at the
hardware (though I have to admit to not having checked in quite a

Subject: Maximum Rims Return Temperature Target?
Hi All,
I know this is a simple question, perhaps one I should be
able to deduce on my own, but knowing how I sometimes
miss the obvious, here goes...
As I mentioned in a couple previous posts, I have a newly
built steam-injected rims that has two batches under its belt.
After some modifications it appears I am able to get
satisfactory recirculation rates. I estimate between 1.0 to
1.5 GPM from the start, but I have not measured this.
What is the desirable maximum temperature of the wort
being returned to the mash tun?
For my second batch on this rims I limited the return
temperature to 168-170 F. range. I could get more, but was
concerned about tannin extraction and possibly denaturing
enzymes.
Limiting temperature in this way limits how quickly I can
make transitions from one point to another. For a given
flow rate I certainly could jump from one temperature to
another more quickly if my return wort was at 190, rather
than 170.
Limiting the return temperature also increases the time to
get to mashout temperature of 168, because the delta T
drops as I approach 168, and I must cut back on steam
input to avoid overshooting my self-imposed target.
What are other rimsers doing along these lines? What is
the maximum recommended temperature for the returned
wort? I'll bet I could go to 175 without problem, at least
when the average tun temperature was on the low side.
I am not sure what the maximum temperature attainable on
my system is, other than steam is self-limiting at about 212
degrees F. My goal is not maximum temperature anyway,
but rather maximum heat transfer from my steam source to
the mash tun. What I try to do is to get maximum
recirculation rate while limiting the temperature of the
return to a safe value. I just do not have any idea what the
maximum safe value is, and have probably set a limit that is
too conservative at 170 F.
I see the rims return wort differntly than an infusion of
boiling water, since no mixing is done and the returned wort
in my system remains in a kind of stratified layer that
gradually works it way downward through the mash. In other
words, the delta T I have across my steam injector is the
same as what exists across the mash itself. The grain at
the top of the filter bed is close to the temperature of
the returned, heated wort.
Any and all comments/recommendations highly
appreciated!

I think it is not so much *mash time* as it is *mash temp*. I think that at
least one reason you are getting more body from a shorter mash is that
you get a more dextrinous product at the high end of the temp range
(158F?), and a thinner, dryer product at the lower end of the temp range
(152F?), shorter mash = less temperature drop, so your mash doesn't
fall into the lower range, or is there for a shorter time. This *may*
explain why some beer has higher FG than others, given similar OG.
That said, a higher start temp and higher finishing temp on the mash
should add the body you are looking for in your beer.

Preferred soil and weather characteristics? We would be growing in
western Washington state, where the climate should be similar to Brussels,
with perhaps lesser temperature extremes.
We are of course aware that this needs long-term commitment in order to
