OTOH, let me suggest an alternative I suggest every few years,
Irish-American Red Ale. Here is my post from several years ago. I've
received good feedback from happy brewers. Feel free to substitute
ingredients or modify procedure, of course. I do think I'd just do a
single step mash for simplicity's sake. Let me know how it turns out if
you do brew it.
-=-=-=-=-=-=-
It's about time to think about brewing a beer for a St. Paddy's Day party.
How about something different from the usual stout or green beer, something
with an American touch? I've made an Irish-American ale that I figure is
similar to what was served in Irish neighborhood taverns in the Northeast
100 years ago, although I have no proof. Maybe like McSorley's? It's sort
of a red ale with corn, flaked barley, medium crystal and a touch of
chocolate. It's a little stronger than a British session beer, a little
less than typical US beers (due to higher FG), and certainly less strong
than the authentic ales of a century ago, but they didn't have to drive
home then. This is popular with Killian's drinkers as well as real ale
fans as it has enough interest to hold them. Resist the temptation to up
the bitterness as it is inappropriate in this style.
McGinty's Irish-American Ale
5.25 gallons @ 1.044
5.5 lbs 6-row (US 2-row should work, too)
1.75 lbs flaked maize
.75 lbs flaked barley
0.5 lbs crystal 30L
2 oz. chocolate
Mash 154F 60 minutes. Actually, though, I did a 40/60/70C mash (30 minutes
at each step) adding the corn at 60C. The 40C rest may have helped break
down beta-glucans in the barley, and passing from 40 to 60 over 30 minutes
or so effectively gave me a protein rest, which may have made the beer
clearer. Irish moss might not hurt.
Bittering hops - Cluster (I used 3/4 oz for 19 IBU)
Finishing hops - Golding (Domestic would be fine) (I used 1/2 oz for 15

Subject: Stuck fermentation... Not!
List:
I had a most amazing thing happen to me moments ago: I found out that the
beer I have in my carboy is going to ferment after all!
Perhaps a little background is in order.
Since I'm still a novice to this hobby, I've been experimenting with malt
extract syrups and pre-hopped malt extracts. I also decided that, as my
second brew, I would try steeping a bag of 60L Crystal malt in the boil to
at least make it more interesting. So, I believe I had followed all the
directions and put the wort into my primary to get started. I shook and
shook it as many homebrew novices would. The wort was still a little warm
(high 80's), but I was anxious and pitched at that higher temperature.
I was mortified by the results. The yeast almost immediately sank to the
bottom and it looked like my beer was going to go nowhere. That was this
last Saturday (1/15/00). The next morning, there was a one-inch thick layer
of sediment at the bottom, and it appeared hopeless. None of the books or
websites told of such things happening, so I feared the worst: my beer was
ruined and would never ferment.
I checked it each day until Thursday, getting more depressed each time. On
two occasions, I nearly decided to pop the airlock and ditch the failed
brew. After Thursday, I didn't bother checking anymore. There was no change
from day to day, and by now there had to be something wrong.
Fast forward to 20 minutes ago...
Imagine my surprise when I walk in and see that it's krauesening and the
airlock is bubbling furiously and beer-making seems to be commencing
normally. I'm both thrilled and troubled, as I have no idea if the beer will
be any good after sitting so long without fermentation going full steam...
So here's the question to the list:
Is a 5-6 day waiting period normal for primary fermentation to begin?
I'll keep the list posted as to the result, as I'm sure you all care
enormously ;)
Cheers,
Randy

Subject: wyeast kolsch 2565 off-flavor
Hello.
I was wondering if any has encountered any off flavors when
using Wyeast kolsch 2565. When I racked the beer into the
secondary, and even after tasting the beer a week after bottling, it
had a distinctive mineral, almost medicinal, taste that seems to
linger. I fermented in the mid-to-upper 60s and did not notice any
obvious quirks.
I am very new to homebrewing - 1 extract and this is my second all grain
recipe - so, it is quite possible that there is a problem in my process.
Although my first all-grain, a brown ale, came out quite well. Thanks in
advance for any advice...

Subject: Mill competition solved!
Hi Y'all,
I've found a solution to the problem of which Mill should I buy/which mill is
best/which mill doesn't charge a handling fee.
I use a JSP Malt Mill (tm) for pale and pilsner malts. It's an adjustable
one, but if I had to do it again, I would go with the standard mill. It's way
faster than the Phil Mill, so twenty to thirty pounds or grain are no big
deal to crush.
For high kilned, dark and roasted grains, I use a Phil's (Phabulous)
PhilMill. This way, I don't get little dark pieces of roasted barley mixed in
with my German lager malt. I can adjust it to just barely crack the brittle
dark grains.
I've never seen a Valley Mill, so I don't feel like I'm letting anyone down.
Is that politicaly correct or what?
I've mounted both mills permanently to a unit of commercial steel shelving.
It's sort of a grain mill 'station'. The JSP mounts on top of a shelf. The
shelf has a slot cut in it. The ground grain falls through the slot into the
bucket below. I like it because it is very rigid, and makes very little mess.
The Phils Mill mounts on a curved steel arm which is bolted the the side of
the shelving unit. The crushed grains fall into a smaller catch bucket. Both
mills have an extended homemade hopper.
Oh, and my old Corona Mill? I sold it really cheap to an extract brewer who
did not have a lot of money to spend.
(I've been thinking of taking the couple of bucks I got for the Corona and
sending it to the Meeker defense fund.)
Best Brewing,

Subject: Bottling with coffee flavors
Primed a few bottles of stout two weeks ago with 3/4 tbsp. of flavored coffee
syrups. Had the first one tonight and it tastes pretty darn good. The
carbonation is much coarser than the carbonation from corn sugar, it is kind
of like bottling with brown sugar or molasses. Doesn't have the nice fine
creamy head that the corn sugar bottles have either. The hazlenut flavor and
aroma is dominant. Wouldn't reccommend doing an entire batch, but try a few
bottles next time you brew a stout.

Yes, I DO KNOW it's a little late, but I try to catch up.
I searched my data base and found, that this chili beer was
even sold in Germany - I drank it in april '95. Written on the
label it had the text:
"Crazy Ed's Original Cave Creek Chili Beer
Black Mountain Brewing Co. Inc."
and was brewed somewhere in Arizona. Its alcohol content
was 4,7% by volume.
Hey, I even found, that I have a thumbnail of its label, but -
sorry! - in awful quality. 6 kB, if anyone is interested...

Anyone ever had problems with a stuck sparge using an Easy Masher? This is
my second try with the Gott Cooler version and second stuck sparge. I crushed
with the JSP mill. I collected my first 2 gallons at full flow, poured it
back in to filter, collected a second 2 gallons of very clear wort at full
flow, then suddenly, STUCK SPARGE. Almost an hour later I managed to collect
my 7 gallons. I ended up getting quite aggressive, racking the screen with
a spoon, moving it around with the spoon ect. I'm very dissapointed, never
had collected wort that clear before, just ended up getting cloudy again from
all the stirring around.

Doughed in using 24 oz per pound of malt using room temp water, allowed to
stand for 30 min, then added 12 oz per pound of boiling water and boosted to
95 F for 30 min (pH 5.38), then boiling water and external heat to 131 F for
1 hour, decocted 0.5 quarts per pound of malt (about 5 quarts, held at 155
for 10 min.) and boosted with external temp to 150 for 75 min. Collected 7
gallons after sparge at 1042. Got a finishing gravity of 1051. The clone
brew book called for 1048 to 1051. Never reached the gravity stated in a
recipe until now. My efficiency increased by 5 to 7 points, apparently due
to the decoction.

Subject: thermowells
Thermowells are usually filled with a heat transfer gel that makes up
for some of the lag time in temp readings. Regardless of what you do,
the readings will be somewhat slower on the uptake. The prime reason
for thermowells is to protect the bimetal strips inside in the end of
the thermometer from bumps and dings as you stir. If there is no chance
of these two things happening, then the thermometer will read more
quickly without the well. The fact that the well is brass (although
most I have seen are stainless) has little to do with the heat transfer
which in the best of conditions is going to be a bit slower. The other
reason for a well is to allow the removal of the thermometer without
creating a hole in the tank.

Hi all,
Just a comment to say that AFAIK its only the Guinness Foreign extra stout
thats deliberately soured. Hidden away at the back of the St James Gate
brewery (Well away from the public on the 'tour') are a couple of wooden
storage vats for extended ageing / souring of stout. Apparently 3% of this
is added to the Foreign extra, before bottling. Of course there are dozens
of different Guinness breweries throughout the world, and they don't always
produce and sell the same beer by the same name.

I never had any trouble back when I bottled lagers (and I'm going to be
bottling some shortly again). I always made sure to pick up just a little
extra yeast when I was racking to my priming bucket. Not a lot, though.
Then prime and bottle as usual. Don't forget to take into account that
you'll have a lot more dissolved CO2 in that very cold beer than in a
cellar temp. ale. There are charts to show saturation levels at given
temps. you'll have to fudge just a little since you'll probably knock some
out with the racking and stirring in of the priming sugar.
Then allow two weeks or so at cellar temps to carbonate and sample. If you
can store all the carbonated bottles cold, that is best.

Dana, I have never tried making starters w/ pump aeration so I will leave
that to others to comment on. I will propose an alternative method that you
may wish to think about - using a magnetic stir plate. This is the way I
make most of my yeast starters. It couldn't be simpler, works great and
seems to avoid some of the complications of using a pump such as the ones
you ask about (need for sterile tubing, need for filtration of the air,
keeping yeast in suspension, etc..) While a brand new stirrer can be
somewhat expensive, if you are crafty (or someone you know is) you can
cobble together a stirrer pretty cheaply from old fan motors and radio shack
parts. Used stirrers are out there too, especially on the net. Feel free to

Hello all,
DeVaux Gauger asks about water filters for removing
chlorine. DeVaux, almost any activated carbon filter will
remove 95-99% of chlorine (and chloramines,) if you keep the
flow within the range given on the filter. If you're setting
up a basement system, I'd suggest a cannister filter. They're
often listed as "below sink" or "whole house" filters, available
for about $10-15 from Sears, among others. The filter elements
vary considerably in price, from about $6 for standard carbon and
fiber on up. The basic carbon and fiber element is rated to remove
95-99% of chlorine and chloramines at a nice flow rate (about 2
gallons per minute, as I recall.) You might want to disasemble
the filter after each use, to avoid bacterial growth.
For those with more experience than I with these filters,
I have a quick question. The instructions (for all the brands
I've seen) specify that one should not run hot water through the
filter, although this is usually paired with a suggestion not to run
any contaminated water through it. Is this just to avoid bacterial
problems, or does activated charcoal have problems at higher temperatures?
In particular, would 120-130F water from the hot water tank be less
likely to be dechlorinated? Would it pick up off flavors from the
filter? I'm asking because my tap water is finally down to near 50F
(good for chilling,) and it takes a lot longer to get 8 gallons up to
mash temperature. It's nice to mash in 25 minutes after starting the
burner, rather than 50. Thanks in advance.

Subject: Faking a Decoction
A member of my Homebrew club and I have a recipe for a MaiBock
that was double decocted. A local brewpub has offered to brew the beer
as a guest beer. The problem is that they can only do a single infusion
mash and much of the beers character comes from the decoctions. What
would you add to a 5 gallon recipe to at least mimic the effects of the
decoctions?
I'm thinking perhaps of adding .25# of belgian aromatic and .25# of
Melanoidin malt. Any other ideas?

Subject: Germany Beer Tour
Hi all,
With plane fare to Europe in the $250-350 range, its just too cheap not to go
while I have the chance.
I have a week, a car, and 2 friends to Brewery hop. (pun intended) The
Preliminary Route is to fly into Frankfurt 1 April, drive to a friends in
Stutgartt, then to Munich, Budvar, Prauge, Pilsen, long trip to Dortmund (via
Berlin?), Dusseldorf, Koln, and back to Frankfurt to fly home 8 April.
That is the general Idea. Aggressive--yes! But alot of fun too! One of us has
been to Germany and speaks some german, but he didn't really go on a "beer tour"
when he was there. So What I am asking for are specific places to visit in each
of the locations. Addresses, Directions, Contact people, phone #s and the like.
Has anyone collected this kind of info before? (other than Michael Jackson?) I
get thirsty just thinking about it.
Eckard Witte--Where in Koln do I find good Koelsch?
After I leave Zum Urgie where is my next Alt stop?
Dr. Pivo--Where do I go in Prauge?
There are a bazillion places to go in Munich. Anyone care to rank them?
Gleefully yours,

Subject: Re: Beer Color (SRM to RGB?)
AJ,
Thank you for your excellent exposition on beer color. However, as a
former computer graphics researcher, I'd like to point out that the
transformation from the tristiumuls values xyY to RGB is not "fixed"
as you imply. Or rather, it is very unlikely that, in general, the
color thus obtained will be correct for an arbitrary computer display.
The commonly quoted transformation between RGB and xyY depends on
having a properly calibrated monitor. Almost nobody's monitor is
properly calibrated. A simple touch to the brightness or contrast
controls is sufficient to decalibrate it. If it was calibrated
yesterday, it is almost certainly not still in calibration today.
Furthermore, the mapping from RGB values to brightness is, on most
monitors, non-linear. Unless your monitor or operating system
incorporates "gamma correction" a doubling of RGB values will cause
the brightness to increase by a factor of about 4.6. So, without
gamma correction, even with a properly calibrated monitor, the RGB
values that are calculated by linear transformation from the
tristimulus values will not give the correct color on the screen. (I
will note in passing that the only computer that routinely provides
gamma correction is the Macintosh. Is it a coincidence that many
graphics professionals still use Macs? Probably not.)
I won't even touch on the problems of mapping on-screen colors to
colors printed on paper, on the differing color perception of
reflected (from paper) versus transmitted (through beer) versus
emitted (from your computer screen) colors; the effects of ambient
illumination on color perception; and so on.
Suffice it to say that a file of RGB values is unlikely to get you any
closer to your beer color than the descriptions commonly found in
homebrew books. And those same RGB values are going to look different
on my computer than the do on yours. And forget trying to print them
out!

Subject: Temp of pH measurements
Brewsters:
Congrats to Rob ( Jethro) Moline on his
recent new Brewster! Thanks for the info
on Lallemand.
- ----------------
Kyle asks about which temperature
we are talking about for measuring pH.
pH is temprature dependent. We have
discussed this here in the past and I
believe M&BS ( and DeClerk?) says make
the measurement at room temperature.
This would make some sense as
temperature compensating probes
were not really available until fairly recently.
I suggest you do this for paper pH strips
as I don't know what would happen to these,
and I have read somewhere ( probably on
the bottle) that these are to be used at
20C.
- ----------------------
A.J when you get back I'd like the
opportunity to more completely understand
your points on using spectrophotometric color
measurement of beer. Do you have
some other stuff written?
Don't the lighter beers remind you of
Corona? They did to me. Same cane taste.
Also try some "cane" distilled liquor if you
haven't already.
Have you been in any sugar storage
warehouses? They are awesomely huge
as is the taste of raw sugar ( illegal in the US).
- ---------------------
DeVeaux Gauger asks about water
treatment systems. I would start
with your home water, but RO is the
best in my opinon as it gets a carbon
filtration as well as purified of all ions.
RO is especially desirable with a well,
but be sure you decarbonate the RO
water by pouring it through the air or
bubbling in air or heating it.

Subject: Body and mouthfeel
Brewsters:
Paul Smith provided some information on
mouthfeel that I think we both agree on, but
I must admit when I finished reading his
note, I couldn't tell if he was saying that
he believes dextrins are implicated in
mouthfeel or not. If he was saying
they do have a positive major effect,
the argument certainly was not convincing
I was puzzled by Table 23.8 which Paul
commented on since it somehow links
OG, isoamyl alcohol, 2-methyl butanol,
total carbohydrate and dextrins under
"flavour terms" called Body, Estery,
Fruity and Viscous. If I read it the way
he did that dextrins were related to
viscosity I would have to believe that
the table authors meant that iso-amy
alcohol corresponds to body, 2-methyl
butanol to estery and total carbohydrate
to fruity... I don't think so. I really can't
understand the table, but I think
Paul's interpretation is incorrect,
if I understood what he meant.
Without reading the paper, I doubt
if a good understanding of the table
can be made. It certainly can't be
used to make a point as Paul
apparently tried to do.
Also, this table has no comment on
beta glucans and proteinaceous
compounds at all, which is what
M&BS says quite clearly relates to
a full mouthfeel in the quote I provided.
I recall reading, perhaps in the old
M&BS or DeClerk that dextrins are
definitely not implicated in mouthfeel
based on an experiment to test the
theory. This is consistent with the M&BS
quote I provided. I just can't locate it.
Dextrins are typically not that high
molecular weight to have a real impact
on viscosity except at high levels and
as M&BS says there is not enough
work to demonstrate a correspondence
of viscosity with anything
I suspect dextrins will be around
30 or so sucrose units at the
maximum if they have been exposed
to alpha amylase for a reasonable
period of time in the absence of beta
amylase. These do not fall into the
class of macromolecules which M&BS
says is necessary ( or at least how
I interpret their statement) to
impart a full mouth or high body.
Paul also states that with highly
modified modern malts for some reason
no proteolysis takes place in the
mash.
Page 270 vol 1 M&BS says:
"More recent experiments indicate
that previously the estimate of
proteolysis during mashing has
been under estimated. Revised
estimates indicate that in infusion
mashes proteolysis accounts for
the formation of half of the TSN
(total soluble nitrogen -DRB) and
half of the amino nitrogen found
in the wort"
I point out that British malts have
always been highly modified. So
Paul's ( and others in the past)
implication that somehow we
cannot effect proteolysis in the
mash because the malts are
already highly modified is incorrect.
Page 270 op cit says:
"The formation of soluble nitrogenous
substrates in mashing is due to
the comparitively heat stable
with carboxy peptidases........
The presence of large quantities
high-molecular weight material,
reflecting < inadequate proteolysis
in the mash >, may contribute to
haze formation in the beer"
Page 269 op cit says:
"The calorific food value of beer
is principally due to the ethanol
and unfermented carbohydrates,
but it is doubtful whether the latter
contribute to any other beer character,
although glycoproteins may act as
foam stabilizers."
I find no evidence that dextrins
contribute to mouth fullness.

Subject: Cave Creek Chili beer
Living just down the road from Cave Creek Brewery I thought I'd give
them a call. Just got off the phone with one of the brewers there.
They still brew on premises and do use saranno peppers. The reason
no-one can find Cave Creek Beer is that they have gone through a
few name changes. Cave Creek Brewery -> Chili Beer brewery -> to
the present day Black Mountain Brewery. Those are the ones I know
of (don't shoot if there are others). He also said that they still
distribute across the US.
So if you see a black mountain chili beer it is the good ole cave creek
chili beer under a new name.
No affiliation other then I happen to brew within a few miles of them
and have enjoyed some of their offerings.

Kyle:
Yes, consider it 'brewhouse efficiency'. That is; 92% of the theoretical
extract of 1.036 for domestic 2 row pale malt giving me 32pts. + per lb. of
malt. This is based on the measure of the OG of the final volume of cooled
wort before pitching.
Big Fun Brewing has calibrated sight glasses on the HLT and Brew Kettle and
volume markers on the 5 and 6 gallon fermenters. The system losses are
measured to keep the efficiency numbers 'based in reality'. These system
parameters are dialed in ProMash and my recipes are repeatable within a point
or two if the exact same ingredients are use. Download the trial version of
ProMash and run the numbers of three or your favorite recipes to get an idea
of your brewhouse numbers.
The malt type/crush makes a measurable difference. Imported DWC malts are
plumper and are a good match for my MaltMill. Domestic 6 row with same
system, mash schedule and Malt Mill, drops my brewhouse efficiency to 85%.
Did a CAP this summer with 6 row and 24% flaked corn and it came in at 82%.
In the past, I would fret over those numbers, but now as long as the beer is
good and the recipes are repeatable, I am happy.

I've been wanting to get a pump to do exactly the same job as you have in

What I've been looking for is a peristaltic pump, ideally with a
