Man, oh man!! I haven't seen this much intolerance for
a LONG time.
So what if someone wants to put vegetables or fruit or
spices, or whatever, in their brew?
If I decide to try something, your long winded post
filled with drivel isnt' going to make me change my
mind.
I have to admit, chili beer is not my cup of tea, but
I have sampled it and I could see where people that
like chili could like it (BTW: Chile is the country,
NOT the food). And there are a LOTS of people that
like it, especially in the Orient, where Cave Creek
Chili Beer is a big seller.

Subject: opinions and -S's boat of dung
If you like beer spiced with jalapeno, habanero, or whatever else, by
all means brew it and drink it. If you don't like it, why spend your
time trying to convince people that it's a colossal mistake or the
result of a simple, childlike palate? Steve, you said yourself that
it's not bad to disagree, so get over yourself and let people brew what
they like. No one said you have to like it, drink it, or accept it as a
bona fide style. Arguments like these do nothing to benefit the
homebrewing community and, in fact, make this digest--at times a
valuable resource--a pain to read. I'm sorry I don't have citations of
peer-reviewed essays and articles to support my stance on this issue.

Subject: RE: Jalapeno Lovers Unite! (somewhere else)/taste in food+beer
I couldn't DISagree with you more! Yes, there is
evidence that tastes evolve over time. But if you
look culturally and historically, most indigenous
dishes are starchy, and overspiced. Need I point out
mexican and Indian dishes? I've never tasted curry
and said, "My that is balanced!" Neither has that
been the case with Thai food. Even eaten Irish food?
That is about as bland and one-dimentional as it
comes. And yet they are masters of beer!
So where are you going with this, -s? Just a culinary
elitist?
Jazz is the only truely original american art form.
The spirit behind Jazz drives authentic american
creations. A benefit of not being a nation with deep
cultural roots, is that we are not bound to cultural
roots. That is the reason Jazz could be concieved in
the Mississippi delta.
So what is the difference in using jalapenos or orange
peel? One is traditional, one is not.

Subject: Skunking and light
There are lots of references out there. But here's a picture.
http://realbeer.com/spencer/bottle.html
What you see here is a graph of the light transmission characteristics
of various kinds of bottles. The higher the line on the graph, the LESS
light of that color gets through. You can see that all glass is fairly
opaque in the UV part of the spectrum, and that the main difference
between brown & green glass is in the blue-green part. So, if brown
bottles protect from skunking better than green bottles do, the
blue-green part of the spectrum must contribute to skunking.
I've got some real references around somewhere, but undoubtedly another
HBD reader will come up with them before I can find them. :-)

There were those who argued in the 16th century hops didn't have any
business being in ale either. Particularly the biships that were producing
gruit and supporting the church with the profit. There were penalties
imposed by the church for importing hopped ales. Another group who will
tell you the ubiquitious hop isn't all its cracked up to be are herbalists.
Hops are a well known estrogenic and diuretic. This makes for a rather
potent anaaphrodisiac in men. There is a condition known as Brewer's Droop
which I think is descriptive enough to get the point across. An
professional herbalist friend of mine refuses to drink hopped beers and so
makes his own "traditional" brews. These have included ingredients like
juniper, yarrow, heather, mugwort, worm wood and so forth. All of these
herbs have a number of medicinal uses and some are purported to make the
beer more inebriating well as an aphrodisiac. Lets not forget that most
primitive/traditional cultures that make beer are consuming it primarily for
religious/ritual purposes. It isn't out of the realm of reason to think
that beers in Europe developed in this manner also. My point being that it
is a bit short sighted to say that an addition of hot peppers to a beer
would be simplistic sort of thinking. Some might say the addition of hops is
a bit of a floppy proposition. If the base beer is for all intents and
purposes is a good beer, the style can be matched to the peppers in a
reasonable manner and not over done then I see no reason why the peppers
would not enhance the beer for those who have a taste for that sort of
thing.

Pick up an Indian cook book sometime. Ginger and cinnamon are in every
Indian dish I have ever made, not to mention the dreaded hot pepper. You
want to talk about pushing the edge of what sorts of strong flavors and
aromas go together? Try making Saag Gosht and let me know what your house
smells like for the next week. More than 1 billion people speaking Hindi

German-Style Dopplebock Tasting Summary
The beginning
On December 28, 2002 three good friends who enjoy beer got together for a
bit of blind taste testing. The style on tap this auspicious evening was
German Dopplebock, a favorite amongst the gathered. Seven likely suspects
were gathered for this flight, a few more than is probably good for testing,
but we really didn't care. BJCP this is definitely not.
Details
The reviewed beers are in alphabetical order:
Allegauer Cambonator
Augustiner Maximator
Ayinger Celebrator
Paulaner Salvator
Sam Adams Doublebock
Spaten Optimator
Wagner Valley (Lodi, NY) Sleddog Dopplebock
Each were evaluated against the (more or less) standard AHA description as
follows:
German-style Dopplebock
Malt sweetness is dominant but should not be cloying. Dopplebocks are full
bodied and deep amber to dark brown in color. Astringency from roast malt is
absent. Alcoholic strength is high, and hop rates increase with gravity. Hop
bitterness and flavor should be low and hop aroma absent. Fruity esters are
commonly perceived but at lot to moderate levels.
Original Gravity (Plato): 1.074-1.080 (18.5-20P)
Apparent Extract/Final Gravity (Plato): 1.020-1.028 (5-7P)
Alcohol by Weight (Volume): 5.2-6.2% (6.5-8%)
Bitterness: 17-27 IBU
Color SRM (EBC): 12-30 (24.0-60 EBC)
Each of the reviewed beers were evaluated by these experienced, yet
untrained, drinkers on the following characteristics:
Appearance
Aroma
Taste
Mouthfeel
Drinkability
Each evaluator rating the categories on an arbitrary scale of 1-5 with half
point increments. At the completion of tasting all seven entrants, each was
ranked from 1 to 7. These rankings were then compared between the evaluators
to determine the best in show. Now on with the results.
Raw Testing Results
(These have been omitted here for space, and the raw text format is not
conducive to tables, as you can see the final summary below. The formatted
version is much prettier and informative.)
Rankings
After the initial evaluation was completed, the testers then rank ordered
each against the other. Here are those results:
Beer T1 T2 T3 Rank
6 Augustiner Maximator 1 1 2 1.3
4 Ayinger Celebrator 2 4 1 2.3
7 Allegauer Cambonator 4 2 3 3.0
5 Sam Adams Doublebock 5 3 4 4.0
2 Paulaner Salvator 3 7 5 5.0
1 Wagner Valley Sleddog Dopplebock 6 5 5 5.3
3 Spaten Optimator 7 6 7 6.7
The best of the flight was straightforward with Augustiner Maximator being
selected as two number ones, and one two. The second best was slightly more
difficult with Allegauer Cambonator getting a two, three and four, and
Ayinger Celebrator getting a two, four, and one. The big disappointment was
last place Spaten Optimator, which had always been held in very high regard,
coming in a very distant last, being bested by the two American entries
which finished almost predictably behind nearly all of the German
contestants. Sam Adams did do a very respectable fourth ahead of even
eponymous Paulaner. Kudos should be extended to Wagner Valley for
respectfully stepping into a very difficult style category which hardly has
a huge following outside of the hardcore beer aficionados.
Bottomline
This was absolutely not a scientific determination of Dopplebocks, but more
of a reason for three friends to get together to have a few beers. I guess
we were running out of reasons for a while, but we're doing better now. No
one in the group is remotely qualified as a judge, but we all know a good
one when we see one. One of us is an active homebrewer (that's me) and avid
beer reader; two is a very active Beer Advocate Mug Clubber who spends many
hours perusing the aisles and internet for something he hasn't seen before;
while three just really enjoys having a few good beers, well maybe more than
a few.
The next time I'm looking for a good Dopplebock, I'll look beyond the
obvious suspects and try something a bit lesser known, but definitely not
smaller.
Future Steps
The next quarterly evaluation will expand slightly with the addition of two
other beer enthusiasts and will cover an appropriate seasonal style which
may prove difficult to fill out adequately: Marzen. (maybe)

From: "Doug Hurst" <DougH@theshowdept.com>
Subject: RE: Jalapeno Lovers Unite!
The brewer formerly known as Steve goes on a long diatribe about taste
combinations in food to explain his disgust for chili beer. Not until
the very end does he give us a real indication of the source of his
prejudice when he writes: "I first tried chili beer about 10 years ago
(Cave Creek), and have several times since and I always think it's one
step better than a phenolic infection and one step worse than excess
diacetyl."
Your problem with chili beer isn't the style, it's the particular
example of the style you've experienced. I agree that Cave Creek is a
terrible beer which is way out of balance. It's a light lager with an
actual Jalapeno in the bottle (if memory serves). It's way too hot and
there's nothing else in the beer to compliment the spiciness. I
remember my first sip was like being hit with pepper spray. After my
second sip I said "this is hot" with a strain on my face and rasp in my
voice. My third sip was only a reaction to wanting something to drink
because my mouth was on fire and drinking beer to cool down was an
instinctual reaction. Of course this only exacerbated the situation. I
think the rest of the 6-pack was used for cooking spicy food.
On the other hand, The Great Dane brewpub in Madison WI once made a
Habanero beer which made me realize this style has merit. It was based
on a APA recipe and wasn't at all overly spicy. It had a nice light
hoppy (fuggle perhaps) aroma. The chili was not evident. The first sip
gave you a nice APA flavor which was malty, somewhat sweet, with a nice
mild estery character. In the second sip you began to notice a slight
warming which actually complimented the spicy hop flavor of the beer. I
was able to finish the entire pint without my face turning red and
breaking out in a sweat. It certainly wasn't a session beer, but I did
have it on more than one visit to the pub.
I think the point is (and -S tries to make this point) that balance is
key. If done excessively chili beer is terrible. If done with
consideration and balance, it can make a great beer. It's similar to
the comments regarding Cascade hops. When used with thought and care,
Cascade is a fine American signature hop. But when heavy hands use too
much it's not fun anymore.
And that's *my* opinion.

Subject: Herb/Spice & Veggies in beer...
I've been following this thread with some interest, since I regularly
brew a Jalapeno Wee Heavy and win with it consistently in the category.
I'd say that your beer can have whatever you *want* in it. Two people
are quite outspoken in their opinion that the flavors just don't belong
together... I'd assert that when done properly, the flavors can make a
very persuasive argument, much like the smoked beers and fruit beers
do. Are there any commercial examples that are successful at this? I
have yet to find one, but homebrewed examples that do so successfully
are numerous. As far as whether peppers are a one-dimensional flavor,
I agree that it's distinctive, but there's an opportunity to go beyond
just the "burn" and successfully marry a richly flavored beer with a
distinctive element that compliments it rather than dominates it. I
had a smoked habanero beer once that was 3 beers from Best of Show at
Dixie Cup... It was wonderfully complex, with rich malt, a tinge of
smoke and a lingering spicy burn that snuck up on you.
I think it's interesting to note that one of the most richly flavored
barleywines I have ever tried was brewed from a very old (I want to say
1600's) English recipe. It included peas and carrots as a part of the
mash!
Experimentation is vital to the growth and health of the hobby. Our
competition, the Dixie Cup, annually celebrates the experimental by
offering a bizarre category designed to get people "outside the box."
Past efforts have included Breakfast cereal beer, Malt Liquor, Most
bitter beer (115 IBU's!), Big & Stupid (24 Carrot I.P.A. anyone?), The
Beer that Burns Twice (High gravity hot pepper beers) and the Monster
Mash (beer made with candy).
But what I find most disturbing about the debate is the vehemence with
which the anti-pepper folks attack the style. Live and let live,
guys... it's just beer and nobody's forcing you to drink it! :-)

Subject: UV versus Blue light in skunking
Guy from Los Gatos, CA asks:
>I thought UV light caused skunking, but someone said that
>it's the blue-violet region ... Could someone please shed
>some light on the subject and/or point me to some good sources?
I do not always fully appreciate the listing of obscure, dated
references in HBD; however a recent article is enlightening for those
with access to the current literature:
"Mechanism for Formation of the Lightstruck Flavor in Beer," in
Chemistry--A European Journal (volume 7, pp 4553-4561, November 2001)
by Malcolm Forbes and coworkers at UNC-Chapel Hill.
His research group followed the photodegradation of isohumulones to
form 3-methyl-2-butene-1-thiol following excitation at 308 nm
(ultraviolet region). Better still, Malcolm is an old graduate school
buddy of mine who always did know how to enjoy a fine pint. At the
conclusion of this study, he swore off Corona.
In Malcolm's words ...
"Although the iso-alfa-acids do not absorb in the visible region, the
thiol can be formed by exposure to visible light, most probably due to
sensitization by compounds such as riboflavin." The sensitization of
isohumulones is still under investigation.
So the answer is ... yes. UV light does cause the formation of "skunky
thiol," but so can light in the low-wavelength end of the visible
spectrum (400-750nm). Apparently, a plastic bottle (UV blocking) will
not save you from skunking your beer. OTOH, it has been reported
numerous times in HBD that cold, dark storage of lightstruck beer will
usually result in the gradual fading of the skunky-flavor.

Subject: Smoothies...and UV Light
I wasn't going to comment on the vegetable beer/blender gourmet
thread--really! But then Tom White replied to the Steak and Potato Cabernet
Smoothie:

"Steak and Potato Smoothie!!! That's a great idea! Thanks. Though, I
think I'll add green beans."
So I find myself remembering a time in the Navy... My friend, John, was on a
liquid diet because his jaw was wired shut after he broke it. He got so
desparate for pizza, that he popped a combo in a blender...and he had to use
some beer to get it liquid enough. Said John: "Mrrmmphhp, Thrt wrph
ggrddf", which I think meant, Mmmm....That was good!
Then, Guy, in Los Gatos asked about UV v. Blue-Violet light
"I thought UV light caused skunking, but someone said
that it's the blue-violet region that causes this, and
it's NOT the UV frequency that causes skunking. Is
blue-violet not considered UV?"
I can't really speak to the specific wavelength of light that causes
skunking, but I suspect it's probably a specific wavelength, or wavelengths,
that cause it. For example, in ultra-pure water systems, you use 254nm UV
light to kill the bacteria. Then you use 185nm UV light to oxidize the dead
particles so that they can be removed by your mixed bed ion exchanger. The
wavelengths required for these purposes are pretty narrow bands--there's not
a lot of difference between 185nm and 254nm...
So, I suspect that when they say "blue-violet" light, it's because most
light sources that produce it will include the wavelengths that initiate the
reaction. Fluourescent lights have a broad blue-violet spectrum, but
incandescent not so much. I'd be very surprised to hear that skunking
wouldn't occur by any wavelength in the UV spectrum, but then it probably
doesn't matter so much. If you're getting UV light, you're also getting at
least SOME light outside that range (and vice versa). Not very many light
sources have such a narrow spectral width as to be consider truly
monochromatic.

Blues band will be there both days as well as food, cigar and brew supply
vendors also all with their own booths. The Cass River Homebrewers will be
brewing all-grain and extract brews for fun and to attract more homebrewers
to the club. Please come join us! We will also have some fresh brews for
our fellow homebrewers to sample.
Hope to see you there,
Mike.

Subject: UV vs. violet-blue light and "skunky" beer
Guy in Los Gatos, CA was wondering about the "skunking" reaction from
exposing beer to UV light versus violet-blue light. The answer is that
BOTH forms of light cause the skunking reaction in beer.
UV light is higher energy, and will actually break bonds in hop oils.
Recombination of the pieces with sulfur-containing molecules gives the
"skunky" product. However, regular glass is a very effective blocking
filter for UV light.
The problem for us is a sensitization of the hop oil by Vitamin B
complexes (which are prevalent in beer). What I mean is that the vitamin
B will bind to certain hop oils - how strongly, I'm not sure - but this
binding rearranges the molecule making it relatively easier to break bonds
in the hop oils. Since these are now easier to break, it can be done with
a lower-energy form of light - specifically the violet-blue region of the
spectrum.
Bottling in brown bottles, really helps, since the amber color filters out
violet and blue wavelengths. Green is OK, but it still allows green light
to pass through it, and this reaction can also happen in the blue-green
region. Clear glass bottles will block UV, as will all the others, but
all other forms of visible light go right through.
Hope this helps your understanding.
Cheers,

Just in case there MIGHT be a digest reader who hasn't
tried it, I wanted to opine that Stone's Double
Bastard
is a MUCH more enjoyable brew, as it has a lot more
malt flavor going on, and better balance makes better
drinking, right? Just my two cents worth.
