>I'm not too interested in the calories, just the carbs.
I was just thinking about this. This would be of value to diabetics, as
well as people like me who are just trying to shed a few pounds.
I figured out a few ways of crudely guesstimating carbs, but hopefully
those chemists out there can do better. Anyway, here goes:
Max carbos could be estimated from the original gravity. i.e. if the beer
was 1.045 OG, this would imply that there is the equivalent of 1 pound
of sugar per gallon since sugar has 45 'degrees' of extract. (I know,
I know. Different carbohydrates could have different gravities.
Remember, I am crudely guessing here.). 1 pound of sugar per gallon
would be about 450 grams or about 45 grams per 12 oz bottle. I think
this would be the outside limit of carbos in the finished beer. I think
some of these carbos break down into non-carbo stuff such as
CO2, etc., so the actual # of grams would probably be less. (Chemists:
please help!)
Looking at it from the viewpoint of the finished beer: If you know the
finishing gravity and the % alcohol (derived from the starting gravity),
you can estimate the residual carbos like above and add to it the
carbos from the alcohol. The biggest fly in the ointment here is the
finishing gravity is distorted by the alcohol being lighter than the water
making up the bulk of the solution. Using this method:
1.011 would imply 1/4 pound of sugar left in solution (see caveats
above) per gallon, or about 11 or so grams per bottle. Now for the
alcohol component: 1 12 oz bottle is about 1/3 liter, or lets say 350ml
(I don't have the exact conversion in front of me). If the beer is 3.0%,
this would be 10.5 grams of alcohol, giving the total carbos to be
21.5 grams per bottle. This method probably underestimates the
actual content. I use an average of this method and that one in the
previous paragraph.
Boy, I sure hope someone actually knows the correct answer to
this one.

Subject: Spring house lagering...rims cleaning
Hello all,
I happen to have an old spring house foundation and a good year-round spring.
Seems like this could be the ideal setup for lagering...or even perhaps for
summer ale making. Just build a new spring house...and I will be in business.
Anyone out there use a spring for keeping the fermenting wort cool? I have
not measured the spring temperature...but in summer it is quite
cold...about 55F or less?
Rims question:
I am probably (almost certainly, already have two kegs...) going to build a
3-tier system...but I wonder...how much hassle is a rims system with
respect to cleaning/sanitizing? We hear much about the advantages of
rims...in the _beer making_ process...but how about the disadvanteges of
rims related to cleaning the system? Much different than a 3-tier system? I
could afford to build a rims I think...but wonder if I would properly
sanitize the system after building it. I can imagine what needs to be done
with the 3-tier...is a rims sysem that much different, for cleaning?
Been lurking for a year or so...don't think the spring question has come up
in this time...if ever. I have tried to check the archives...but mostly
find seasonal spring or mechanical spring...

Subject: Berliner Weisse questions
I'm planning a Berliner-Weisse as my first all-grain, any advice from the
gurus is welcomed. Guessed (5-gal) recipe so far is:
2.5# pale malt (2-row or 6-row?) (American or British?)
2.5# German wheat malt
0.5oz Hallertauer (probably Yakima Valley, USA type) - 60min
0.5oz Hallertauer - 10 min
Leftover AmericanII Wyeast from last low-gravity batch
Infusion mashing in 5-gal brewpot with homemade EZmasher, target 155F.
60 min full volume boil.
Crash chill with immersion chiller to 70F.
Rack off trub and debris, primary in plastic for ~three days.
Split secondary, half over raspberry fruit, half plain.
At racking to secondary, add unknown quantity (I've read 1tsp/5gal) of 88%
food-grade lactic acid to taste.
None of the books I've looked at (so far) have any info, besides style
descriptions and mention of L. delbruckii inoculation at pitching. I don't
really want to pitch bacteria this early in my experimentation, so I'm
willing to just go for the 1-dimensional sourness of lactic acid. In all
other ways, I want to keep it as simple as possible on brewday.
Thanks for any help you can offer.

Subject: Re:Thermostat
Jon, The reason you are not supposed to cycle a freezer at higher
temperatures is because at higher temperatures the compressor is running
at higher internal pressures causing the compressor to work harder.
If you set a thermostat up with a differential of about 3 degrees (F)
you should not have a problem.
I purchased a Ranco thermostat which has a LCD readout of actual
temperature, diagnostics, a 1 to 33 degree F adjustable differential, a
built in timer to prevent the compressor from turning back on after a
power outage (this prevents compressor overload if you had a brief
outage or brownout).
Available at WW Grainger here in the states. Ranco number
ETC-111000-000.
It also has a flexible temperature probe that won't get damaged by
laying it between the lid and the base of the freezer.
I bought it for about $50.00, this is probably one of my better finds.
Incidentally for all you gadgeteers, Ranco also makes a temperature
controller (same style) with a 0-10V analog output.
I suppose you could use this for heating as well because it is a
heating/cooling thermostat and has a operating range of -30F to 220F

I don't think a bronze body is going to hold up real well against the
acidity of the wort. Ideally it would be made entirely out of
Polyphenylene Sulfide (PPS- Ryton TM, Fortron TM). My pump is made out
of Polysulphone which really is a bit overkill from a design standpoint
for our application, but I couldn't get one out of PPS. Incidentally,
I bought mine from Moving Brews. Don't have the address but they are

"My initial batch used 9.5 lbs of grain and 3.5 gals water. This fills a

I would think that changing nothing but the fan blade size (smaller)

Sounds like you are having fun but I feel it's only a matter of
evolution that folks gravitate to 10 gallon batches sooner or later.

Hello brewers,
AJ writes in HBD 2664 about a microscope. I have bought a used one (in
good condition) and I'm trying to use it for checking my brews.
Enlargment possible 15 x 40 and even 15 x 100 with oil-immersionlens.
But I'm not sure how to distinguish between small bacteria (coccus,
sarcina) and trub. I can recognize for instance Lactobacteria (rods with
approx. 1/2 length of the diameter of a yeastcel (not often Thank

Is there a good book which I should read?

Subject: baker's yeast
Jeff Renner and HBDers,
I was interested in Jeff Renner's recent HBD post (#2670-13) on baker's
yeast.
My understanding was that baker's yeast (e.g., Fleishman's) has an
enormous supply of glycogen and that this must be depleted before the
yeast uses an exogenous sugar. In fact, when I was a biology TA (at
Univ. of Michigan, BTW), we used baker's yeast for student
demonstrations/experiments which were based on very well known studies
of yeast respiration from the 1960's (by Britton Chance et al. of the
Johnson Institute, Univ. of Penn.). One basic experiment compared two
batches of yeast:
Batch #1 preparation: dissolve baker's yeast in buffer and "wash" them.
Batch #2 preparation: dissolve baker's yeast in buffer and "wash" them,
then "starve" them for 2-3 days by vigorously bubbling in air.
We had students measure respiration of the two batches of yeast with an
oxygen electrode. Batch #1 respired rapidly; however, respiration did
not increase when glucose was added, presumably because the yeast had so
much internal glycogen. Batch #2 respired slowly because it had little
internal carbohydrate; however, adding glucose dramatically increased
the respiration rate.
I have difficulty reconciling these results with your post that baker's
yeast use the carbohydrates present in flour. Could you please
enlighten us?
TIA,

Subject: Element in boiler
First of all, thanks to all who answered my question on "mash water
calculations" a while back. I tried all the calculations/programs, but I
still didn't get close to the amount I use. I haven't had time to perform
any experiments, but next time I'll check the temp. of my "boiling" water. I
suspect that might be the problem.
To the point; we plan to upgrade our brewing system to 12-13 gal batches. We
have a great SS vessel, and our intention was to use an electric water
heater element in the boiler. Would a 4500 W (240 V) element be OK, or would
it scorch the wort? Has anyone tried this? (we use 240 V here in Europe). I
know low density elements are the ones to use, but on
PlumbingSupply/warehouse/world.com (does anyone know this company??) I saw
something called "Extra Low Density incoloy/wrinkle style" elements ($23).
Is anyone familiar with this type of element, would it be better to use in a
boiler?
Advice apperciated
TIA,
Lars Bjornstad

Subject: Using a handpull beer engine to dispense from corn kegs
Hi All,
I am intending to add a corny keg setup to my bits and pieces to play
with. I have found a homebrew dealer in the UK that sells everything I
need (Kegs are expensive at 35 pounds each). One thing I noticed in the
shop was a really nice handpull beer engine that I think will look great
on the bar.
How can I connect this up to a corny keg? According to the guy at the
shop you can only pressurize the keg to 2-3 psi, before it overcomes the
seals in the handpull and out flows your beer.
I know about setting up a balanced dispense system by varying the length
of the beer line, does this only affect the dynamic pressure drop whilst
serving, or does it also decrease the static pressure while the tap is
closed.
I would really like to hit the keg pressure up to about 25 psi and then
drop it down using 12 ft of 3/8" dispense line. If I can't do that then
I intend to get a 3 or 4 tap Scottish style dispenser, which really
looks the business.
Wassail and TIA

B-Brite is NOT a sanitizer, it is a mighty effective cleaner, but has no
or very little sanitizing capability. If you don't believe me, read the
label and look for the word "sanitizer", you won't find it. The only
batch of beer I ever infected was when I assumed, as do many folks, that
B-Brite would sanitize my starter bottle. It did not, and I know this
because the starter was used in a split batch and only the one half got
infected (the other non-infected starter was boiled and cooled in a
Pyrex flask).
I still use B-Brite for most of my cleaning needs (it is the most
effective remover of hop residue I've seen). I think a lot of folks get
away with using B-Brite as a sanitizer simply because it CLEANS so well,
but in my experience, it can't be counted on to really kill any bugs. (I
hope this doesn't start a war, as this is my first post here).

Subject: Dunkels
HBDers -
Matt writes in distress about the lack of Dunkle formulations around. Try
and get a copy of an old BT (spring 95, i think); it had a very interesting
article on this style. The upshot, as I recall, is that most German
brewers go with a mash of almost 100% Munich malt and either double or
triple decoct. I simply love this style -- and its brother, Schwartzbier,
and was also disappointed that it did not make Ray's book (guess you gotta
stop somewhere).
Here are my suggestions:
Use at least 50% Munich malt, with the balance lager (Klages is fine) and
specialty malts
I like to use a measured amount of special B and Biscuit
I also use a small amount of chocolate malt (1/8# per 5 ga), even though
the AHA Guidelines recommend against this
Try a bunch of different Munich malts -- I used 3 kinds this year: Durst,
Monravian, and DWC
I wouldn't think of using anything but Wyeast Bavarian strain, preferably
on its second pitch
You've got the IBUs pegged right -- depends a lot on you water sulfate
makeup -- but hop flavor is up to you. I personally don't like to have the
hop flavor compete with the maltiness of the brew. A Schwartzbier, OTOH,
is a bit heavier and has the malt backbone to stand up to some pretty hefty
hop flavor additions.
Happy Brewing,

Well, I leave the detailed biochemistry to biochemists or microbiologists
(although I do have an M.S. in biology myself). Baker's yeast may have
lots of glycogen, but I suspect that they are reproducing, so that in
itself would decrease the glycogen reserves per cell. Regardless, I suspect
the glycogen reserves would be depleted pretty quickly. At any rate,
bakers' yeast certainly consumes sugars and produces alcohol and CO2, just
like brewer's yeast:
>From _Ingredients for Bakers_, Samuel A. Matz, Pan-Tech International
(McAllen, TX: 1987), p 51: "The sugars which are consumed in fermentation
are usually the simplest sugars glucose or fructose which result from the
action of enzymes on the larger molecules of sucrose, maltose, starch or
similar relatively complex carbohydrates. ... starch and dextrins cannot be
broken down by bakers' yeast. Enzymes present in flour, or diastaatic
malt, are responsible for the production of sugars from the starches
present in doughs."
If it weren't for this phenomonen, dough would hardly rise at all. I
certainly see evidence of this all the time, as I posted, in the slower
browning of loaves of long fermented dough in the oven. A slice of my
French bread (fermented >18 hours) takes a much higher toaster setting to
color, than does commercial 3 hour bread. (As you probably know, there is
a similar movement in the bread business to brewing for hand crafted,
quality, traditional products- I have a "microbakery.")

I would be very happy to hear from those of you who re-pitch your yeast from
batch to batch. How do you wash your yeast? I have read about washing the
yeast before re-pitching but very little on the actual mechanics. I use a
conical fermentor that works great for harvesting the yeast, but it is never
the beautiful creamy white layer that is read about even after allowing it to
set in the refrigerator and settle. I brew mainly light colored German style
lagers but there is always a lot of gunk mixed in with the yeast coloring it
as well as creating a very unpleasant look. I have tried adding water and
decanting it off of the bottom numerous times and it gets better, but never as
good as I would like. It works well when repitching with very little lag
time, but I usually cringe when I pour it back into a new wort. I haven't
been able to detect any detriment to the finished product however so maybe I
am worry too much. I would appreciate any comments.

Subject: Talking Thermometer
A month or so ago the HBD's own blind brewer was inquiring about a
talking thermometer to assist him with his brews. I stumbled across
what is called an alarm thermometer. It has an audible alarm that
signals when the temp is out of your range. Here is the VWR catalog
description:
* Traceable
* Reads in Fahrenheit and Celsius
* Audible Alarm Signals Out of Range
* Auto Alarm Reset
Perfect for measuring temperatures in cuvets, gas systems, soil, water
baths, incubators, foods, waste water, etc. Designed for years of
reliable service even in severe lab or harsh plant environments.
This VWRbrand Alarm Thermometer measures to 0.1deg. with accuracy of
1deg.. Readout and alarm ranges are -67.0 to 298.8deg.F and -55 to
148.8deg.C. When temperature rises above or falls below the programmable
set point, an audible alarm signals. Alarm automatically resets when
temperature returns "in range." Alarm mode may be switched off.
Supplied with a fast response, universal 17.8 cm probe (liquids,
semisolids and air/gas), with 3 ft. cable. Equipped with replaceable AAA
battery. Supplied with a serial numbered certificate to indicate
traceability to standards provided by the National Institute of
Standards and Technology. Six year warranty.
Description VWR Catalog # Price
Alarm Thermometer 61161-274 42.75
You can find the VWR (telephone 1 800 932 5000) catalog at:
http://www.vwrsp.com/catalog/catalog2.html
I am not sure, but I am guessing that this thermometer has a memory so
when you shut it off it will retain your range. This could be perfect
for mashing, just set a high range of 151 F and a low range of 149 F,
crank up the heat when the temp falls and the alarm sounds, then turn
the heat off when it sounds again. Maybe you could get another one for
the sparge water.

Do lactose and Malto Dextrin have the same effect and can they be used

the Lactose/malto dextrin be added at bottling so I only run the risk of
ruining half the batch? Is lactose mainly for stouts? If so does it's
effects go beyond just "body" - i.e. is there an effect on color, head
retention, reduction in bitterness (it is a sugar of sorts - yes?)?

My questions are 1) does the Wyeast 2565 "Kolsch" yeast throw a corn/DMS
twang? 2) Did the absence of the cold lagering and subsequent DMS
consumption rest at 60F contribute to the corn smell? Does the DMS fit
in the kolsch profile?
Incidentally, Ray Danials in "Designing Great Beers" makes no mention of
water softness for Kolsch, while the latest BT article on Kolsch
emphasizes soft water is essential. The excellent BT issue came too
late for me to use a blend of RO water as per my lagers.

Subject: hop tea haze
Dan Morley reports that adding a hop tea at bottling time made his
beer hazy.
My guess is that the hop tea introduced tannins (polyphenols) to the
beer and these reacted with the left over protein and created
protein/polyphenol complexes that manifest as haze. Basically this
is a chill haze that occurs at room temp. It will settle over time,
perhaps over a long time. The good news is that it has no effect
on flavor.
Cheers!

Subject: RE:Munich Dunkel
In HDB2672 Matthew Arnold asks for help with a recipe for Munich Dunkel:
Matthew,
I too wanted to brew this fine style after a recent visit to Vail,
Colorado and sampling (or more appropriately quaffing) it at a new
brauhaus (sp) there. I searched all over for some recipes and didn't
find much. I personally have never followed any recipes exactly, but
more or less use them as guidelines. After reviewing Greg Noonan's book,
New Brewing Lager Beer, I decided to use his recipe for Munich Dark as a
guideline. I have long regarded him as the Lager Guru for sure!
Anyway, I came up with this following recipe and brewed it about a week
ago. I cannot attest to the outcome yet because it is still in the
primary fermenter, but all signs indicate that it will come out fine.
Here it is:
Grand Slam Dunkel - 6 US Gallons
Water - 9 gallons (6.3 pure, 2.7 tap) .25 tsp Citric acid for 5.8 pH
Treatment - 1 tsp CaCO3, .5 tsp CaSO4, .25 tsp CaCl
- (note: All salts added to the mash)
5# - Weyermann Pilsner Malt
5# - Weyermann Light Munich Malt
2# - Briess American 6 Row Malt
1# - CaraMunich Malt
8 oz - Crystal Malt (40L)
2 oz - Chocolate Malt
1 oz - Black Patent Malt
1 oz - Mt. Hood hop plugs (4.2% - boil 75 min)
1 oz - Liberty hop plus (3.3% - boil 45 min)
1 oz - German Mittelfruh (yes real ones!) whole hops (4.8% - boil 15 min
1 tsp Irish Moss Flakes (in boil 15 min)
1800 ml Wyeast #2206 Bavarian Lager
I used a combination single decoction, step mash routine with the temp
rests at 105/138/153F and did a 10 min. mashout at 167. Lautering and
boiling and all the rest is pretty much the same as any lager brewing.
The above recipes numbers are a touch high according to AHA style
standards as far as IBU's are concerned, but that all depends on how you
figure your hop efficiency. Additionally, I ended up with alot higher OG
and extract efficiency than I had planned. I collected 6.25 gallons of
1.064 wort which according to my brewing software is about 91% EE. YMMV.
It might have been due to the new MaltMill (tm) I used or the decoction.
The jury is still out on that one! (See recent post in HBD). I am now
fermenting it at 50F and plan on doing a 48F secondary and then lagering
it for a month or so. I do six gallon batches so I can keg 5, and bottle
the rest for friends, competitions, etc.
Anyway, just thought you might like the recipe.
Good Luck and Cheers!

Subject: Proposed USA Federal 0.08 percent driving limit
Greetings,
I apologize for this use of bandwidth. I want to explain to our
foreign readers why some of us oppose the proposed USA federal 0.08
percent blood-alcohol driving limit.
I also want to get our USA readers to contact their congresspersons.
I don't believe this proposal is about road safety. It's about
building a national prohibitionist political power base. We don't
want that. It's the kind of "salami" tactics that gave us prohibition
before. (Get the salami one slice at a time.)
Note, however, that many MADD people work with states, cities and
communities for education, more road patrols, stricter and more
even-handed sentencing. These don't build a prohibitionist power
base, they just reduce accidents and deaths. I applaud these people.
I hate drunk driving. A friend and mentor of mine, and his family,
were killed by a drunk driver. Someone who drinks and drives home is
a murder waiting to happen.
But I oppose this particular federal boondoggle.
FIRST, IT WILL ACCOMPLISH NOTHING. No horde of drivers is being
stopped, released for a BAC of 0.08 to 0.10, and then wreaking havoc.
As James Tomlinson said on alt.politics:
85 percent of ... crash injuries involve drivers with no blood
alcohol at all. [Of the rest] 93 percent involve drivers with a
BAC of 0.10 or higher.
David Howse writes that Australia has had a uniform limit of 0.05 for
years. The state of Victoria doubled random breath testing from 1994
to 1994. 20% fewer people died, and the number of drivers testing
over the legal limit decreased 21.6%. He meant to support a 0.05
percent limit, yet his own data show that the difference was improving
enforcement, NOT reducing the limit.
People either drink and drive, or they don't. They don't monitor
their blood alcohol to within 0.02 percent. This mandate will make no
real change.
SECOND, IT WILL DIVERT ENFORCEMENT FUNDS. Changing a law costs a lot:
reprinting documents, retraining officers, publicizing the change,
processing borderline cases. That money comes from the same bucket as
enforcement money. James Tomlinson noted:
this proposed federal bludgeoning will divert limited police,
prosecutorial, and judicial resources away from drinker-drivers
that account for 93 percent of the problem and toward a low-risk
group that accounts for only 2.6 percent of the problem -- which
is exactly why the founder of MADD, whose daughter was killed by
a repeat offender with a BAC over 0.20, is publicly opposed to
lowering the permissible BAC.
THIRD, MATTERS LIKE DRUNK DRIVING POLICY ARE STATE ISSUES. In the
USA, power is balanced between the states and the federal government.
The states would be blackmailed: enact Federal policy, or they'll tax
you anyway and return nothing. Yes, this has been done before. It
was wrong then, it's wrong now.
Yours for responsible and safe brewing, consumption and government,
Samuel Mize

<snip>
Seems as though the people at Wine & brew By you INC. have had a change
of heart. About 8 years ago, I placed an order with them and received
nine-month-old Wyeast. When I called and complained that the package said
that it should be used within 4 months, I was told by a very angry
man to send back the yeast and that he would refund my money. I told him
that I did not contest the fact that the yeast could still be used to make
fine beer but rather that I did not want to pay full price for outdated yeast.
He then said, "I know who you are... you're one of those guys from
the brew network!" He refered to us as "a strange group of weirdos"
and "cheapskate weirdos." He said that he has been brewing for
30 years, and knew more about brewing than anybody on the network.
Strangely enough, he *asked* me to tell you to not order anything
from him. He repeatedly stressed that his was "a legitimate business"
not "some guy working out of his bedroom." I would like to point out
that I never said anything to incite this kind of reaction, was very
polite as I asked for reimbursement, and even gave him several chances
to apologize. He continued to flame about us digest members.
He said that he will make a batch of beer with the yeast I return to
him, he will use $50 (!) worth of malt, he will have Mr. Mossberg review
the beer and post the review to the digest.
I sent back the yeast AND the devices for modifying a keg to draw beer from
the top in stead of the bottom. Alas, eight years later and I still have
not gotten a credit for the $23.70 desipite several phone calls.
Now, it seems that Wine & brew By you INC. feels that we in the HBD
may know something about brewing. Well, I do happen to know what
yeast you have there and I'll tell you if you send me a check for $23.70.

P.S. I still haven't seen a review of the beer by Mr. Mossberg, incidentally.

Hops have a lot of polyphenols. Despite the small amount used (relative
to the weight of the malt), hops contribute about 1/3 of the polyphenols
(tannins) in the beer. When you boil hops in wort, you are boiling them
in a liquid that's 5.5 pH or less. When you boil or steep them in plain
water, you could have a pH of 7.0 or higher! My water is around 8.5
out of the faucet.
I suspect that you added a lot of polyphenols with the hop tea and these
complexed with proteins to give you chill haze. You can remove some
of this haze with Polyclar (PVPP), but be warned that this will reduce
the bitterness a little (5 or 10%).
You also probably added some oxygen via the straining which is part of
the polyphenol-protein chillhase problem... I've read where only oxidized
polyphenols will contribute to haze.

David Hill asked:
> What are the advantages of yeast storage under distilled water
> compared with just holding a bottle of beer in the fridge?
First, it isn't distilled water storage, it's *sterile* water storage.
Big difference. The water (and test tubes, petri dishes, whatever) is
usually sterilized by holding it at 240F for 15 minutes in a pressure
cooker or some other autoclave-type device.
I'm not sure whether you mean storing a large volume of harvested
yeast from a primary under water, or you're talking about storing
small numbers of cells for long-term storage. I'll assume the latter.
I've been using this method for a couple of years, and I maintain over
a dozen different strains (and growing). I've had no problems
re-culturing after over a year of storage.
The idea with sterile water storage is to get the yeast to go dormant
by removing all sources of food for them. What dormant actually means
to a yeast cell I don't know, but I assume their reproductive/survival
mechanism basically slows down to a crawl. If yeast are left under
beer, then they will not go dormant since there will still be
nutrients around that they can process, including other yeast cells
that have bit the dust. I've never used the method myself, but others
here and in books (sic) have mentioned being able to store yeast under
beer on the order of a few weeks without problems. I've stored large
volumes of yeast harvested from a primary under water for a few weeks,
but longer than that and all I have is a jar of (effectively) dead
yeast.

Subject: Garbage bag fermenting and mudbugs
Hi all,
I have several 15 gallon plastic barrels that I got from St. Pats
that were used for shipping extract. They make good primary fermenters
but are a real pain in the butt to clean. Even if you think they're clean
you really can't see into them good enough to be sure. I heard somewhere
that you can use a big plastic garbage bag to line the fermenter. Is this
true? It would make life much easier to sanitize a bag and insert it
through the bung hole, rack into it, and hold it all in place with the
airlock. Any specific type of bag needed or will it produce off flavors.
To Kathy coming down I-65, I'm sure by the time you hit southern
Alabama you'll be able to find some Mudbugs. They're in prime season
right now. they will be around most of the summer but tend to be much
bigger in the spring. Get em spicy hot and find someone serving crawfish
ettouffe (sp.) Yum, yum!
