With well-modified malts I don't think that the increase in nitrogen levels
is not as big a factor as if the malts were less-modified. Also, this
increase, I believe, has been a small amount over the course of the last
25 years, so I don't think that it is a "problem" that we need to immediately
address in our brewing.
The level protein in your wort can be a positive or a negative, depending
on what you are trying to do AND on the size of the proteins. Amino acids
(the building blocks of proteins) are yeast nutrients, for the most part,
although higher levels of some can increase higher alcohol levels (each
higher alcohol has a corresponding amino acid associated with it's production,
if I'm not mistaken). Small and medium-sized proteins are what give beers
body and head retention. Large proteins are what's in hot and cold break,
chill haze (after reaction with polyphenols, aka tannins) and are reported
to give bacteria something to eat (although if sanitation is good and
the levels of bacteria are low, we're simply talking about the difference
between long shelf-life and shorter shelf-life). If you are really
interested in this stuff, I recommend Malting and Brewing Science (about
$200) and DeClerck's A Textbook of Brewing (about $100).

It is a misnomer used typically by homebrewers and some professionals, but
not growers or dealers, I think. Most hop growers call them "raw hops" bu
some also say "whole hops." Please note that I'm not talking about
homebrewing supply wholesalers (some of which do (incorrectly) use the term
"leaf hops"). To the best of my memory, I have never seen "leaf hops" in
anything from HopUnion, Freshops, J.I.Haas or H.H.Steiner.

Perhaps I was unclear, but what I meant was that we should not equate
"pale malt" with *JUST* "lager" and "pils" malts. Similarly to what
Jim is pointing out here, , In another post of mine, I pointed out that
Schreier Malting does not label their basic malt with any of these titles
and rather calls it "2-row Brewers' Malt." In my experience, it behaves
like and results in beer that implies it is more like a "Pilsner" malt than
a "Pale Ale" malt.
I am not aware of any midwestern distributors that carry Gambrinus or
Canada Malting and therefore have not seen their literature. If they
do have a "Pale Ale" malt and "Pale" malt, it seems that this would
result in a lot of confusion, wouldn't it? If they don't have a "Pale
Ale" malt and indeed this is their only pale-coloured base malt, then
it's simply important for brewers to know that when they buy Gambrinus'
or Canada Malting's "Pale" malt, it behaves like a "Pilsner" malt (i.e.
has higher levels of SMM, lower levels of melanoidins and lower levels
of caramelly flavours). Alas, many retailers buy whatever malt they
get the best deal on that month and don't label it with the maltster's
name or even what the maltster calls the malt.
Just as it took a while for the retailers to get pressured into using
the proper (oxygen barrier) hop packaging, I imagine it will take some
time for them to realize that homebrewers really *do* care if their
"American 2-row" is from Schreier, Canada Malting, GWM, Gambrinus, etc.
Fred's post regarding "Light Peat" versus "Medium Peat" is a similar
issue. How hard is it for retailers to label their supplies properly?
I'm planning to do my part in this battle and hope that you all join me.

Subject: Infusion mash
Hello!
1.) With a single step infusion mash it seems that the idea is to add the
cold grains to hot water so that the final temperature is somewhere between
150-158 F degrees. Why not simply heat the grain and the water together
untill it reaches the target temperature?
2.) Charlie Papazian in his book "The New Joy..." claims that Alpha-amylase
works best in the 149-153 degrees F range and Beta-amylase works best in the
126-144 degree range but that the two enzymes together work best in the
145-158 degrees F range. Why would the ideal be so much higher with the two
together? Why not 144-149 degree F range?

Sorry Brian, I have to disagree. Carbonation is carbonation no matter
how you make it: priming or forced.
Incidentally, this reminds me that I ran into Brian at the Real Ale Fest
in Chicago this last weekend. I'd just like to note that despite the
lines at the beginning of the fest, it was fantastic! Sunday there were
no lines at all, incidentally... It is rare that I can go to a beer
tasting an not have ever tasted 80% of the beers. Furthermore, except
for one unfortunate cask, all the beers that were air-freighted from
Britain were great. Fuller's ESB won Champion Beer (surprise, surprise!)
and all but three or four beers were at least very good. 30 cask-conditioned
ales from all over the US and Britain (Marstons, Fullers and Youngs) all
either on handpump or gravity feed (and some even available on both!). It
was great! I'm sure there are still shirts (nice, embroidered polo shirts),
handpumps and other stuff available for sale (contact Ray Daniels at
71261.705@compuserve.com) if you are interested and you can let Ray know
you want information on the 1997 Real Ale Fest when it becomes available.
[No, I'm not making money on this. I'm just a satisfied customer].

I did this and I'll tell you what I've found: I bottled the entire batch
and lagered half the bottles at 40F and the other half were at 60 to 70F
for six months. After a few weeks, there was no difference. After the
entire six months, the cold-conditioned (lagered) bottles were *fruitier*
whereas the warm-conditioned were very slightly more bitter. All I can
suggest is that perhaps the warm-conditioned bottles' yeast kept working
a little longer and lowered the FG a little making the beer appear to be
more bitter. Odd, no? I still have a few bottles left, although they
are now over a year old. The bitterness has faded (from the initial
50 IBUs) to what *tastes* more like about 30 IBUs. I should really taste
them again side-by-side and see if the differences have evened out.

That was me and I was referring to crystal malts and dark grains and this
is only true if you have relatively low carbonate levels. If your carbonate
levels are high, you either need to pre-boil your water before using it to
steep the grains or you must use less water. The issue here is the pH of
the steep. You can buy some pH papers and check it -- if, after adding
the grains, your pH is more than 6, you need to either pre-boil and decant
the water off the precipitated carbonate or use less water or add acids.
Also, the darker the grains, the more carbonate/more water you can tolerate.
Darrin also asks:
>I'm confused about enzymes and conversions (not to mention

Any reasonable brewing text will tell you which malts need to be mashed and
which don't although I have seen a recent release (Beer From Kits) which
tells you to steep crushed toasted malt (without mashing) and this is
absolutely wrong.

Maybe, maybe not, but if in doubt, put fences around the hop plants.
I did it to keep the bunnies from munching them, you would just have
to use a higher fence. I used a sort of graduated fencing -- it is
more dense at the bottom than at the top (probably because taller
animals have bigger heads, right?).

While I am a great fan of cask-conditioned beer and am a card-carrying
member of CAMRA, I want to address the last point made by Geoff. According
to Philippe Perpete (studying for his PhD in Brewing at Catholic University
in Louvain, Belgium, if I'm not mistaken) the addition of sucrose actually
*DECREASES* higher alcohol production. Since higher alcohols have been
implicated in (or at least many have suggested that they are associated
with) hangovers, it seems to me that it may be wrong to simply blame "added
sugars" for hangovers. I think that the production of higher alcohols,
if indeed they are the source of hangovers (and my experience certainly
correlates with this), is quite complicated and the factors infolved are
not all fully understood. Consider that high fermentation temperatures
are blamed for higher alcohol production (this is proven), but that there
are significant levels of higher alcohols in many lagers, which are
fermented at cooler temperatures. Clearly, there is no simple answer
here.
Incidentally, 50-55F is the proper temperature for serving English Ale
(this from Mark Dorber's Cellarmanship lecture at the Real Ale Festival
this weekend) not room temperature. I'm sure Geoff meant cellar temperature.

Careful... remember that the enzymes are in the *liquid* part of the
mash and that having a larger amount of liquid under the screen and
being subjected to direct heat could result in more enzymes being
denatured during the heating periods. Personally, I feel that if
heating by direct fire, the smaller false bottom would be safer.
This is not to say that it cannot make good beer, just that you need
to be more careful with a larger volume of mash liquid under the
false bottom.

I can't tell you. No, really, I can't tell until you add the water to
the grain. If you want to know in advance if you will need to add
calcium or acids, scale your recipe down to 1 ounce of grain (like
7/8 oz of pale, 1/8 oz of crystal) and then add 2.5 ounces of water to
the crushed malt and mix well. Check the pH. If it is between 5.0 and
5.5 you are in fine shape. If it is between 5.5 and 5.8 you will probably
be okay for the mash, but will need to acidify your sparge water down
to maybe 5.8 or so. If it's well above 6.0, you can try again with
pre-boiled and decanted water. If that fails, you had better be prepared
to add a lot of gypsum (if it's a pale ale) or acids if it's a low-sulphate
style like a Pilsner.
***
Please, please... don't mess with sanitizing the inline air filters. If
you use them always in the same direction and sanitize the hose and
stone, you should be just fine even if the media did not come sterile.
You will introduce far more wild yeasts and bacteria transfering the
wort than you will by using an unsterilized air filter.
***
Regarding making a mead starter, I'm not a mead maker, but it seems to
me that a malt-based starter would be fine and would have a lot more
nutrients than a juice- or honey-based starter.

Sure. The flavour was from higher alcohols which were created by the
high-temperature ferment. As long as you don't filter or centrifuge
the beer, the yeast will convert the alcohols to esters by a process
called esterification. I'll bet that not only is this beer smoother,
softer and less harsh, but it also smells fruitier, right? A good
Barleywine (in my opinion) will be undrinkably harsh for at least 6
months.

Subject: The Soghrum Beer Challange
Fellow brewers,
In August a number of us witnessed a thread that began with comments
about IBS's recent facination with sorghum malt; ending with a challange for a
few brewers to make a batch of sorghum beer, "opaque beer, " then describing
the
result with the HBD crowd.
The recipie for six liters was as follows:
1 K Sorghum Mash
.5K Unmalted Winter Wheat
10g Generic Ale Yeast, Muntons
Cooked crushed wheat on a boil for 15 minutes. Removed liquid. Added
sorghum and enough water to paste the grains (looked like creamy oatmeal). Kept
mash at 65 degrees C for 90 minutes. Sparged with six liters of 75 degree C
water. Let cool naturally, measure OG (calculated to 60 degrees F), pitched dry
yeast when "wort" was at 30 degrees C. Airlock was active in about three hours.
Everything went well for about 24 hours, then fermentation slowed to a trickle.
Racked and cooled in the fridge.
The first taste caught me off guard. Fellow homebrewers, you've never
tasted anything like this before. It had a unique aroma and taste, sort of
reminded me of fermenting Japanese saki. The texture milky and a color similiar
to Yoo Hoo chocolate drink. The wheat added the after taste. I also tested
this on my wife, she's not a beer drinker or even a sipper, but she's the one
that found to words to describe the aroma and taste. Her father used to make
his own saki.
It's drinkable enough that I plan to finish the six liters I have (with a
little help from unsuspecting friends and neighbors), but I wouldn't choose it
over an Andek Pils or an Erdinger Weizen.
I want to thank: Michel Vandenplas for the opportunity to make a truely
exotic fermented beverage. It's people like you that help us deepen our
appreciation for our hobby. Bill Ridgely for all the recipies and advice on
ingredents and methods.

Subject: Keg vs. Gott mash/lauter tuns
I am currently working on putting together an all-grain setup. Initially,
I intended to use a converted keg as a kettle and a 10-gallon Gott cooler as
a mash/lauter tun. However, I now have 3 kegs (2 50L and 1 30L). I'm now
thinking that I could save some money by mashing/lautering in the 2nd 50L
keg and use the 30L keg as a sparge water tank. Is the geometry of the 50L
(13 gallon) keg suitable for mashing 5 gallon batches? I wondered if it might
be too large in diameter (too shallow a grain bed).
On a similar note... is there some reason why I really should go with the
Gott setup? Is it much easier, for example? I figured that I could use some of
that spray-in insulation and a cardboard 'mold' to make a jacket for the keg
to help maintain a more constant temperature during mashing. Since I have to
get some welding/cutting done on my other kegs, an extra keg shouldn't be
much more. Perhaps the added flexability of being able to boost the temp. of
the keg with direct heat is well worth the effort?
any thoughts on all this babble would be most welcome...

IMHO There are three choices, No. 1 on my list is Hugh Baird pale ale malt and
No. 2 would be Munton & Fisons Pale ale,and No. 3 would be De Wolf-Cosyns Pale
ale malt. The first two are grand examples of classic English malts that seem
to fit the style you are brewing. DWC is a Belgian malt I like to use a lot of.
It has a different taste than the British malts but it is not a "weak" malt in
any sense of the word. Give them all a try and post what you think is the best
for you.

Depending on where you live, get a bag of British pale ale malt or the
equivalent from a North American maltster. Out here in the Northwest, we
can get very good ale malts now from Gambrinus and Great Western, but
British malts are pretty spendy after having been shipped all this way. If
you live back east, British malts might be less money. Could be that Briess
or Schreier is now making a 2-row ale malt. Check it out. But in any case,
the flavors will be better than using 2-row lager malt.

Ray, except for the gushers, your problem might not be an infection.
I've had inexplicable (due to anal-retentive cleanliness levels) sour
batches in the past and found that my fermentation temp was too high.
Your's was 75F, around where mine were. I lowered my temps by putting
the fermenter next to the open door of a "dorm"-sized fridge set on low
(power, not temp) and insulating (sorta) the open areas with a towel.
I'd have prefered a less wasteful method, but the carboy just doesn't
fit in there. For milder temperature control, you can use just a wet
towel around the fermenter and/or an iced water bath. This kept my
temps in the 60's. I've not had a problem with this since.

I started doing starters around the time I started all-grain brewing (ie,
four or five batches ago). Here's what I do:
Take an erlenmeyer flask (while you can do without one, the fact that you
can boil in it right on the stove and then plunge it into an ice bath
without worrying about it breaking is fantastic) and put 3 level
tablespoons of extra-dry DME in it. Add 2 cups of water. Put it on heat
and boil gently (it may tend to foam over if you're not very careful with
slowly applying heat) for 15 minutes. Cover with foil soaked in iodophor
and pierced with a couple of holes to let air in as the mixture cools. Put
it in an ice bath.
Once it's cooled down to 70-80F (I usually wait unitl 75), take it out of
the bath, remove the foil, cover with an undrilled stopper that's been
soaking in iodophor and shake the living daylights out of to aerate. You
should get a ton of foam.
I should've mentioned that, at the same time you made the iodophor bath for
the stopper and foil, you should have put an airlock, scissors and
thermometer in it as well. At this point, as the foam starts to recede,
soak the corner of a Wyeast packet in iodophor for a few minutes. Shake
off the excess but don't rinse it. Cut with scissors and pour carefully
into the flask. Immediately put the airlock in place and place the flask
in a dark place, I use beneath my sink.
You didn't specifically ask, but allow about 24 hours from the time you
smack the packet until you pitch it into the starter (adjusting this time
for the age of the yeast, of course). Allow about 24 hours from the time
you make the starter until you're planning to finish your brew day. I
personally don't worry overmuch about pitching exactly at high krausen, I'm
not sure it's really all that detectable in a 2C wort starter.
I look forward to anyone pointing out problems or improvements to this....

I help keep my carboy a little bit cooler than the ambient air simply by
placing the fermenter in a $5.00 big plastic bucket I got at my local
hardware super-store, filling it with an inch or two of water, and wrapping
a wet towel around the carboy. It wicks water up from the pool and the
evaporative effect helps keep the carboy around 5*F cooler than the
surrounding air.
This especially helps during summer months, when it costs *way* too much to
run my AC at 65, and I don't have a second fridge (yet).
As for whether it changes the flavor, higher fermentation temperatures tend
to produce more off-flavors than do lower ones. I'd stick to the
low-to-middle range for the strain you're using. In general. :-)

Subject: starter conundrum
I built a 40 oz. starter wort and added the sediment from two bottles of
SNPA last Wednesday. By Saturday morning the starter had shown little, if
any, activity. Upon inspection there appeared to be about 1/3 inch of
yeasty sediment in the starter. Perplexed, I picked up the starter and the
slight agitation caused the airlock to begin bubbling. I figured the
starter was just getting started and left it alone. Later that day it was
not showing any signs of activity so I picked it up and again the airlock
began bubbling. I then shook the starter and it formed a thick head and
the airlock began blooping so rapidly that the water shot out the top of
the airlock. Anywho, I pitched the yeast Sunday and the wort was boiling 7
hours later. Has anyone else had similar experiences with this yeast, or
with any yeast for that matter? I know what you are thinking but no, the
airlock was not clogged. For some reason the starter decided to carbonate
rather than give off CO2. Truly strange...
BTW, here's a nifty improvement for listermann's psyphon starter: replace
the plastic ball with a stainless steel ball of the same size. Psyphons
far faster with half the hassle. (say that fast)

Subject: RO Water and Nutrients
I exclusively brew with RO water because of water problems in my area (lots
of hardness and oily scum). I seem to have more than my share of stuck
fermentations. I have just read a letter from a subscriber in Brewing
Techniques (Sept/Oct 96) Readers' Tech Notes column about trubless
fermentations. This isn't my problem because I don't rack off the cold
break in my ales and only occasionally in lagers. But the editors response
did get me to thinking, Don Put suggested that RO water has almost all the
minerals and healthy fermentation nutrients stripped out. This made alot of
sense to me because going through my records I noticed that any ale that I
made where I
Burtonized the water always fully attenuated. As background information, I
am an
all grain brewer, I usually pull my yeast off of slants, use yeast
nutrients in my starter, have half of a gallon of starter fermenting when I
start brewing, use an aeration stone to oxygenate my cooled wort and
usually have active fermentation within four to six hours of brewing.
Does anyone think adding yeast nutrients to my wort would solve my problem
(I use G.W. Kent
Yeast Nutrients for my starters). Or should I be adding a base line of
minerals back into my water? If I add a base line back in, I would like to
stay light with a Pilsen or Belgium soft water profile and beef up from
there for specific styles. Does anyone think that would be sufficent
minerals
and what would they suggest for minerals and concentration to add to my
water?
Thanks....Bill Ballhorn (sometimes stuck in Iowa).

While it's true that there is a group of mints called bergamots, the plant
which gives Earl Grey tea its flavor is actually a citrus, _Citrina
bergamia_ (from the Italian city Bergamo). The rind of the bergamot orange
is used to make a greenish-yellow liquid called oil of bergamot. I agree
that I'd certainly hold out for food grade.

While it is true that there is a group of mints (in the genera _Monarda_
and _Mentha_) called bergamots, the plant that gives Earl Grey tea its
flavor is actually a citrus, bergamot orange, _Citrina bergamia_ (named for
the Italian city of Bergamo). Its rind used to make oil of bergamot. I'd

That is not the real thing, but an American plant of the mint family (also
known as Oswego tea). True bergamot is a tree of the citrus family (Citrus
aurantium bergamia) with small orange-like fruit. The essence known as
"oil of bergamot" is extracted from the rind of that fruit.
The principal flavoring ingredient is linalyl acetate, which is used
extensively in perfumery.
In the amounts needed as beer flavoring there is no problem of insoluble
oils. It is very intensely flavored and a few drops will go a long way.
I bought my oil of bergamot in a pharmacy in France some years ago. I
don't know whether it is readily available in the US, but a small bribe to
a chemistry graduate student should be able to produce linalyl acetate
quite readily (Aldrich cat # L280-7; CA # 115-95-7).

I would sincerely doubt it. Our sense of taste is pretty sensitive, perhaps if
you drank the entire batch at one time you would ingest enough copper to be
harmful, but I really doubt That much copper dissolved due into the wort.
>2. Will the copper taste diminish in the bottle over time?
If there is a lot of yeast still in the bottles, it might.

I would always store the chillers dry. You should clean it thoroughly after you
are done using it though. Use a detergent such as B-Brite to make sure it is
clean and rinse it thoroughly with hot water before draining. IF the water in
your area causes copper pipes to corrode, turn green, then you should add some
amount of vinegar to your rinse water. The amount will depend on your local
conditions but diluting it to a quarter would probably be a good place to
start.
After rinsing, allow it to drain as much as possible. With use, the metallic
taste should disappear.

Subject: Dream Six-Pack Results
In #2220 Kenny published the results, reporting a few votes for Bud, to his
surprise. I can honestly say that I would also specify a Budweiser over
Pilsner Uruquell, based on the fact I've never had a drinkable one, and if
I had to have just one six-pack, I'd not want to take the chance!
Now, if someone can point me to a source of draft PU in Colorado, I'd
appreciate it! I'd really like to give this a fair shake. As for the
Celit Wit--yes I agree, assuming I had nothing else to brush my teeth with!
