Subject: Rice And Nasty Names
I am a little bit behind trying to respond to Jeff Renner on the matter of
rice mashing. Every so often I am unceremoniously plucked from home and sent
off for several arduous days work. I find it most disruptive!
All I wanted to say on the matter of rice mashing was that Jeff's last post
completed the picture for me. I asked how can you mash ungelatinised rice?
Jeff explained he grinds it first.
Now I realise he is doing with rice just as he does with corn. I have
followed Jeff's corn procedure in the production of Mudgee Mud and found the
whole process to work very well. And I think during the consumption of that
beer, the six scantily dressed ladies brought along their younger sisters
and cousins as well! It was not around for long and even the sample I had
saved for Jeff was consumed (though I recall I was the culprit responsible).
This discussion started because I mentioned that I had switched to using
flaked rice to avoid the cooking process. Jeff has enlightened me yet again.
On the recent spat of nasty name calling, I must apologise. Doc Pivo is not
usually allowed anywhere near the keyboard unless under constant supervision
and heavy sedation, but every so often he sneaks out on his own. To all
nerds, whimps, dolts and narcissistically inclined personalities, I am truly
sorry for your being named. We hope this outrage will not happen again.
We also hope that you will not be asked to read the same HBD ten times over
as I did with HBD #3282. I kept asking myself "Just what point in here is
Pat desperately trying to drive home?"
Apparently there was no point at all.
Cheers
Phil.

Subject: Mail order Phil's Philler?
I asked this once before, but the post didn't go through or something (?),
so it didn't get answered. In any case, my wonderful brass Phil's Philler
broke ... something about a 1/3rd full carboy coming down off a counter and
bouncing around the kitchen while trying to bottle my latest creation ...
and now I need a new Philler. Local brew shops do NOT carry it anymore and
don't seem to be very successful at getting them ... who knows why?
Listermann Mfg's web site gives the impression that they don't do mail order
directly.
Does anyone know of an online store, or have the phone number of a shop that
does mail order, that DOES carry the Phil's Philler? My initial searches
have turned up zilch ...
Also, it seems I remember that the Phil's Philler was offered for a time
with either nickel or chrome plating ... is my imagination going wild, or
does anyone know anything about this? If it's true, then is the plated
version or the plain brass version better? Why?
Thx MUCHO Amigo!

Subject: mashout
Steve said >>Tables show that 1 pound
of stuff in a gallon of solution at 20C gives:
dextrose(glucose) SG = 1.0435
Fructose SG=1.0465
sucrose SG=1.0461 (see AJ's 1.04622 note in HBD 3205).
maltose SG=1.0461
dextran (avg weight 420 glucose units) SG=1.0438<<
>>You seem to be confusing 1gal of solution containing 1# of stuff
(typical brewing measure) vs 1# of stuff added to 1gal of water.<<
The references I looked don't specify If it is 1lb in 1 gallon of solution
or 1 lb into 1 gallon of
water. Looking at your numbers and the variation from the 1044 for sucrose
I mentioned would
seem to point to that my references were 1# into 1 gallon of water. This is
also indicated by the
extreme difference between our numbers for the gravity of glucose; if
adding 1 lb of glucose to 1 gallon
the water of hydration would depress the specific gravity.
>>No literature or experiment anywhere suggests
that lowering temps can increase BA activity again. The thermal
denaturing of malt BA is irreversible and the specific activity is
monotonically increasing with temperature.<<
At least as legitimate as you 11 trails sans mashout; I have tried at least
that many in a Phils
lauter tun, I found that if I wrapped 1 towel around the tun my RDFs
stabilized and foam stand improved. Wrapping a second towel around the mash
tun maintained the temperature nicely. Keeping my mash temperature "up
there" indicated to me that there was significant effect on RDF. A
particular session
comes to mind where it was -10 degrees out and the wind blowing in the
window was coolling the mash tun
significantly, no,_a_lot_. I mashed in at 160 and every 10 minutes had to
add boiling water to raise the temperature back up from 154 or 155. This
beer finished off about as dry as any I've tasted.
Do consider that if any B amylase survives (even 10%) as temperature
slips downward the BA now enters a range of its' most aggressive activity.
Causing an even more rapid reduction of the starch.

Personal communication with Dr. G. Fix . He didn't mention his source. I
used to skip my mash out also,
believing the texts that the enzymes were denatured by the end of my 162
rest. It wasn't until I started doing
a mashout that RDFs became what they were intended and foam stand became
superlative. I don't know maybe it's just coincidence.
>>after finishing a mash I'd like to save time and get up

>> It cannot "save" energy since you expend even more energy when you
boosted the mash + grist. It also can't save you TIME unless you
ignore
the mashout boost and rest time.<<
Read what I said carefully. I was refering to getting things up to boil. I
guess you haven't been at the computer for a week or so, business happens,
Dave asked me this but since I use hot water from the water heater little
time is spent heating mash and sparge water, and I do realize a savings in
propane this way.
As to the Tuborg experiment.
>>Proctor malt,
mash-in 30'@126F, boost to 145.4F for 60' then boost to mashout
172.4F for 10 minutes. All boosts at 2C/min rate. Wort sampled
at 10' intervals and enzymatic action was prevented in the samples.<<
With such a long rest at 145, no rest at 158 why would there be significant
change in extract with the
mashout?
>>Detailed carbo assays were performed and the pre-mashout wort
was evaluated as 70.5% attenuable vs 70.3% after mashout.
At the 2C/min pass through Alpha range I would expect only a slight drop in
attenuability.
The experiment doesn't show what lautering at 145 would do to brewhouse
efficiency. I have purged my in basket and can't quote back positively but
your original "skip the mashout" post seemed to infer that a low
temperature lauter was OK and wouldn't hurt mash tun efficiency; you had
cited an experiment of a lauter
approaching 1 degree C (wasn't that to avoid tannin extraction?). The
Tuborg experiment proves nothing to this issue. If I understood correctly,
and you quoted exactly, all samples were pre-lauter.
>>"Del sez so", just isn't the basis
for an interesting or productive discussion.<<
Well, it has become that, so maybe it was! To counter, your "skip the mash
out" post didn't offer more
than some test batches in your brewery and the blanket statement that we
shouldn't be recommend a mash-
out in the HBD.
Isn't that just a "Steve says so"? In fact, that's what got me fired
up.

Subject: FWH ?
Bob McDonald asks >>Everything I've read
about hops says that the delicate aromatic compounds
that provide hop aroma and flavor are driven off in
the boil. If this is so, how can hops added before
the boil add flavor and aroma? <<
I think _perhaps_the key here is the "driven off in the boil" aspect.
Since in FWH the hops steep in wort
below boiling, it is possible that the aroma compounds have time to bind to
the wort in a way yet to be described; so that when the boil is reached
they can't be driven off. Purely conjecture though, but it seems to work.
And Lynn says,>>The use of the term FWH is creating some
confusion because it has been too narrowly defined based on the Brauwelt
article. I would like to see it used to mean simply adding hops to the
first wort. One could also have middle wort or late wort hopping. FWH
should not carry any implied meaning of omitting the last addition IMHO.<<
I agree, (see I wasn't ripping on you before), though I wish there was
some more indication of the time needed in the not yet boiling wort to
produce the desired effect. In the article I read they mentioned that in
late hopping some undesirable character was added to the wort, so a late
addition may undo the purpose/benefit of FWH, the beer would still in
essence be FWHed.
This is America, brew your beer the way _you_ like!

I use a brinkman burner. To fix this problem I went to the hardware store
and bought 3 small C clamps. Clamp them on the top outside ring of the
burner at equal spacing and let the keg sit on the clamps. This simple
modification allows you to remove the clamps when it comes time to actually
use the burner with the intended grill.

Subject: Great new product
just stopped by my local homebrew store and saw what I though to be one of
the greatest new products available on the market.
This is a product called MicroWorts. What they have done is contract with
some of the local microbreweries to aseptically package their wort right off
the same line used at the brewery (there is a tap right before the chiller
for packaging). This wort is vacuum packed full volume wort. Simply open
the container, add yeast and let it ferment. Of course, you can transfer to
a carboy or add anything you want to make it special.
The product is about $18.00 and contains 2.5 gallons of wort. This is great
for the "Mr. Beer" guys just trying brewing out for a lark and for the
experienced brewer that occasionally runs out of beer and can't schedule a
days brewing session. Since these guys will deliver anywhere in the
country, this also gives people the opportunity to have readily available
beers that they ordinarily can not get locally (Think Doninion Ale in
California). Currently available are beers from Dominion Brewing in
Ashburn, VA with other local DC area breweries coming on-line soon.
This is really cool. Not just for beginners, but for everyone wither as a
fill in or to try new beers quickly and fairly inexpensively.
Check it out at http://www.haveahomebrew.com/microworts As always, no
affiliation just a satisfied customer.

Guy asks about using rye, and I like this especially in my 'lawn mower
beer'. I know this will bring up many other notes, but for me lawn mower
does not imply american style pilsner. I want something smooth, interesting,
with hop and malt in nice balance, and with a low OG for quenching my thirst
in volume. I like to drink it cold too so the typical ale is not what I am
after. I use pils as the base malt and ferment with an english ale yeast and
then cold condition, keg, force carbonate, and have a nice hot summer. Basic
profile is as follows:
Modified pils base 52%
Biscuit 15%
Munich 15%
Flaked Rye 18%
Single temp infusion 152/53F OG 1.037 FG 1.010 ABV ~3.3%
West coast hops equal parts by weight 60/30/15 mins for 20IBU

Dan describes exactly what I have with his Brinkman burner
and modified sankey keg set up. The lip of the keg fits
precisely on the outer ring of the burner. You probably
wouldnt get a closer fit if it was designed to do so.
The only problem is that the keg WILL fall off the burner
with the slightest bump. Dont even think about firing it up
without modification.
At first I tried clamping the keg to the burner with four
C-clamps positioned at 90-degree intervals clamping the
inside lip of the keg to the burner ring. This didnt work
so well. At first the calmps were tight, but after turning
red-hot from the flames, I wasnt so sure they would stay
tight. Once they cooled, it was almost impossible to
remove the clamps. Anyway, It worked, I didnt get
burned, but I dont recommend it.
You need to permanantly weld support tabs to the
burner ring. I used pieces of 1/8th-inch thick by 1-inch
wide steel stock for tabs. You can get a 4-foot length
(about 3 feet more than you really need) of the stuff
from any hardware store for a few bucks. Cut (hack saw)
the stock into 4 pieces; each piece with a 2-inch length.
Put about 1/2 of the length of each 2-inch long piece
(about 1 inch, duh.) in a vice and hammer away so
that you get a nice 90-degree bend in it.
Get a welder, or find someone who knows how to weld
(I finally found a use for my un-employed brother-in-law
who speciallized in welding technology at vo-tech school)
and weld the support tabs around the outer
ring of the burner. Position the tabs so that they are
located just ouside of the outside wall of the keg.
Make sure you have your modified keg handy so you can
place it on top of the burner and position the tabs correctly.
I used four tabs and they work extremely well.

Subject: FWH definition
To my way of thinking, FWH should be defined by the objectives we are trying
to achieve, namely improved hop flavor and aroma. The procedures would then
flow logically out of that. A broad definition as you propose MAY not result
in the desired effects. Factors such as wort temperature and steeping time
could be an important part of this, and I think it is important that we not
lose sight of that. As for the final addition of hops for aroma, only
experimentation will tell us whether it is necessary or detrimental, and
whether FWH improves the quality of late additions. Although I am not
familiar with the research in question, I am told that George Fix feels that
late hop additions contribute negatively to overall beer quality, and I
would certainly like to know more about this.

I agree with this and it is my practice to still use some late addition
hops when I FWH. I think the brewers reported on in Brauwelt were trying
to test FWH agains late additions and so would have left late additions out
for testing purposes so as not to confound the results.
Bob McDonald <rcmcdonald@yahoo.com> asked:

That's the big question that no one on HBD has found the answer to yet,
either in the literature or otherwise, but it really works. There is a
summary of FWH by Dave Draper at hbd.org, I think.

Hi everyone. MCAB sure was a pleasure. I was most impressed by the quality
of the hospitality beers brewed up by the members of the St. Louis Brews.
Here is a toast to Bob, John, Terry, LuAnne, Mark, Louis, Pat and everyone
else involved in this fine event.
Several of you in St.Louis mentioned that you were interested in joining the
AHA so that you could vote on the slate of AHA Board of Advisor candidates
in the upcoming election. Each AHA member gets four votes (one for each open
slot). The candidates are Scott Abene, Pat Babcock, Louis Bonham, John
Carlson, Jr., Steven Mallery, Dave Miller, Randy Mosher, Lynne O'Connor and
Martin Stokes. To receive the May/June Zymurgy, which includes the
candidate statements and ballot, we need your membership by this Friday,
March 31. Friday is the day we run the report of mailing labels to send to
the printer. The Zymurgy mails April 13, with ballots due by a May 15
postmark.
This issue of Zymurgy is the first since Ray Daniels has taken the helm of
Zymurgy, and is the highest quality issue in my opinion since I came on
board in 1998. The focus is on honey and brewing, both from a beermaking and
meadmaking context. Ray has diversified our author pool to include Ken
Schramm and Dan McConnell, Byron Burch and Brad Kraus for this issue. I urge
you to take another look at Zymurgy and vote for the new AHA Board
candidates. You may join the AHA at http://www.beertown.org.

From: cbuckley@newsoft.com
Subject: yeast and alcohol
I have two related but separate questions.
I have been looking at some different recipes for high gravity beer. My
questions are about yeasts ability to live in high alcohol, and attenuation of
high gravity worts. First question is how much alcohol can a "average" ale
yeast tolerate? secondly is the attenuation needed to produce a high alcohol
beer from a high gravity wort. I'm assuming that I am using the word
"attenuation" correctly. To me it is the amount or percentage of the available
'food' that a yeast strain can ferment. I have made one lager that had an
apparent attenuation of 83%. I have had ales as low as 60%. Back to the
recipes. I have seen some recipes that show a OG of 1.090+ and a FG of 1.014.
To me that is close to 85% attenuation from an ale yeast and an alcohol of 9%+.
If that's true than why don't my lower gravity worts finish with a lower FG, or
85+/-% attenuation.
I have made six ales and one lager all from extract. All have tasted good
(the lager is still conditioning). Two have been stouts that started at 1.048 -
1.050 and finished at about 1.014. That's about 72% attenuation. I have not
seen a connection between a higher OG and higher attenuation. I would like to
try a beer with a OG around 1.080 and I want to know where the FG should be. Is
it dependent on the extract or malt? Do I need to use yeast nutrients or
enzyme? Can I get high alcohol and attenuation with extract? Am I way off in
my thinking or am I missing a big piece of the puzzle?
I hope that doesn't sound too much like the ramblings of a pure novice (I
am one though) and I thank you for any advice or clarification.
On another note ---- a couple of weeks ago I asked a question about yeast
starters and why I should use them. Well I did use one in the stout that I
brewed last week and the lag time was less than 12 hours!! I was able to rack
it after only four days in the primary. While that may not sound impressive to
some of you I'm very excited. Previously I had lag times averaging a few days.
Thanks to all who responded and helped me decide to use starters.!! I'm
glad there are experienced people out there that are willing to help us newbies
understand how everything works.
Happily brewing in NH

Ok, it is becoming clear that the Stainless tubing is painfully
expensive. Is it acceptable to use copper refrigeration line instead??

Subject: Cell Counts
Sorry for the delay in getting back to this. I spoke yesterday with the
gentleman at Analytical Food Labs (AFL) who did the tests.
1. Only viable cells were counted. Cells were not counted by
microscope--this is typically done only in the dairy industry. Several
plate dilutions were counted (log 2,4,6,8,9 dilutions for each sample).
2. Contamination testing was done. No contamination was found, only product.
3. Regarding 1" thick:
This issue, i.e., when is the optimal time to pitch Wyeast, was the main
focus of these tests for me. In my original post I understated how many
Wyeast packs were checked and at what thickness. AFL checked numerous
packs ranging from immediately smacked to fully risen at a number of
thicknesses to answer this question. This was an iterative process that
funneled down to the 1" thick pouch.
AFL states that Wyeast is at its optimal when its 1" thick because this is
the point at which there is maximum cellular budding of the yeast. After
this point there is a little more growth of yeast, but the wort (food
source) is being used up and the yeast are starting to give off their waste
products and saturate their system leading to a falling off of viable yeast
until they reach a stationary phase. Also, alcohol is being given off and
the activity of the yeast starts to decrease.
What is interesting is that the optimum time to pitch does not coincide
with maximum cell counts, which occurs a little later.
4. Jim Liddil wonders why Analytical Food Labs data is more or less valid
than that included in the Zymurgy 1998 special issue. I will repeat that
the tests that I reported were done by a professional lab, that the yeast
suppliers had no knowledge whatsoever that the tests were going to be done,
the products got to the lab in about as good a condition as possible.
Here are the facts of which I am certain regarding the Zymurgy article.
The cell counts, for both White Labs and Wyeast, in the table of the
Zymurgy special issue were provided to the author by White Labs. This is
not stated in the article. The White Labs data sheet containing these cell
counts clearly states the tests on Wyeast were done on 2 week old packs
obtained secondhand. This information is not provided in the article.
The Zymurgy table contains information that disagrees
with what is printed on the Wyeast package although there is no explanation
as to why or on what basis the author chose to disagree with this information.
The Zymurgy article contains the recommendation that brewers should
pitch 3 vials of White Labs for a 5 gallon batch (if the vials are over
1 week old). That's ~$20/batch. The author offered the following
insight "It may seem like you are spending a small fortune on yeast by
doing this,"
There was a Zymurgy letter in a following issue from White Labs that
disputed some of the information in the article, viz,
it wasn't really necessary to spend $20/batch on yeast,
that the White Labs retail price in the table was off by 50% or more, and
that White Labs shelf life was much longer than stated in the table and
text.

Subject: Counterflow chiller
Greetings, all.
I'm planning on making a counterflow wort chiller using 3/4"
ID copper tubing with 3/8" OD copper tubing inside. I'll use
refrigeration tubing for the 3/8" because it has half the
wall thickness, and I figured it would transfer the heat
quicker. Hopefully this will save another 30-60 minutes on
brew day.
My plans are this:
Solder a 3/4 X 3/4 X 3/4 tee on each end of the outer
tubing, then solder 3/4 x 3/8 reducers to them. I'll have to
drill out the 3/8" end of the reducers to remove the small
stop tabs, and then run the 3/8" tubing thru the whole
thing, soldering those connections. I'd leave an inch or two
extending out to clamp my 3/8" id vinyl tubing on to. Then,
solder reducers on the tees and clamp on my water supply
tubing (also 3/8"). Actually, I'll assembly it dry and then
solder the whole thing.
I was wondering what the minimum overall length of the
tubing should be to be effective at chilling to within 5
degrees of the water. A 25' coil would cost me about $50 to
build, so I'd like to make it smaller if possible. I noticed
St Pats now has such an animal but they use stainless for
the inner coil, and theirs is 11 ft. long. I have to wonder
about its effectiveness since stainless is not near as good
a conductor of heat.
Does anyone have any ideas on how long I should make it?
Thanks
Steve

I have one of these burners too and a keg and agree that it is not a
good idea to have boiling liquid with such a close fit. I put a metal
grate on the burner and the keg on it, works great.
