Subject: Warm-Side-Aeration????
Al writes about HSA:

If you mixed equal volumes (2.5 gallons each) of, say 200F wort with
40F water, I assumed the resulting mixture would stabilize initially
at approximately 240/2 = 120F (Actually higher since the thermal
capacity of wort is higher than water). Ignoring thermal capacities,
the volume of hot wort would have to be less than 1.875 gallons to
bring the final temperature below 100F in a 5 gallon batch. This
would, of course, require a very concentrated boil.
I guess the only reason I pursued this is the question of how cool
does the wort need to be to discount possible HSA? Is 120F considered
safe? I thought it would be much cooler. The reason I ask this is
that I have toyed with the idea of building some sort of aeration
gadget that would connect to my Easymasher spigot to aerate the wort
during chilling when the wort had cooled down to a "safe" point. My
immersion chiller is very efficient taking boiling wort down to a
certain point, but takes forever to take the temperature further down
to pitching temp. I envisioned pumping filtered air through the
spigot into an immediate elbow that would jet the air alongside the
inner wall of my kettle. This would serve two purposes: initial
oxygenation of the wort; and provide a whirlpool type movement of the
wort around my chiller without having to move the chiller manually
(the lid stays on). I gave up on this idea for two reasons -- HSA,
and the need for a fairly powerful air pump to make this work. If HSA
risks can be discounted as high as 120F, I may actually pursue the
second problem. What does the collective think? Does this have any
merit worth pursuing? More importantly, what would Dateline think?
If they say its a no-go, then that's the end of that :-)

If they're grown over here (and here isn't Kent), they sure as hell aren't
East Kent Goldings. Goldings, sure, but... I've had some wonderful Goldings
from British Columbia, but they don't taste anything like the British blend.
Something changes hops when they're grown in different regions, even from
the same cultivars. One of the reasons why Saaz hops from the Czech Republic
are in such high demand, even with attempts to grown them elsewhere. The soil?
Dunno, but probably. Same goes for Goldings; you can plant them elsewhere and
even grow them, even get good hops, but they simply aren't the same thing.
But use the hops anyway; you've got 'em and they'll certainly make good beer.
===========
On the subject of sanitizing carboys: do you guys really soak carboys in
bleach for a week? Whatever the hell for? Is there some magic point
(beyond one hour) where chlorine sanitizes?
Maybe it's time to switch to Iodophor (hint: two minutes).

Hi all,

*rant mode on*
I also don't like the disappointment of buying a promising looking micro
only to have it turn out to be swill. But please, please don't advocate
more government regulation. If it's a health issue, fine. But every
homebrewer should be aware of the history of prohibition (gov't regulation
gone wacko) and the devastating affect that it had on U.S. brewing in
general and homebrewing in particular until very recently. We, as consumers
already have an arsenal of weapons to combat fraud in the marketplace.
Complain to the establishment that sold it to you. Complain in writing to
the brewery. Most of all, don't buy the product again, and tell everyone
you know not to buy it. The price of an insipid sixer is small indeed
compared to the specter of *big brother* legislating proper beer styles.
*rant mode off*
Ed also mentioned a tasting where all homebrews were appreciated, with the
exception of a chili beer. It sounds like Ed makes good beer, so I guess
they just weren't chili heads. I am planning an amber chili ale (non-chili
lovers be damned) and would appreciate some tales of grand success,
collossal failure, or just guidance on varietal preferences, fresh vs.
dried, primary vs. secondary, etc. E-mail would be great.
TIA.
BTW, Just about split a gut when I read John (the Coyote) Wyllie's musings
on bergamots, marmots, and Dr. Suess mopheads. Thanks John (and others) for
the humorous side of beer. It really adds a lovely aroma (as in late
hopping) to the digest.

Subject: Botulism, bleach, my first batch of mead
Dear Friends:
I started. My first batch will soon be ready. I decided to prepare a mead
first. Next time I will go for my first batch of beer. So far, everything
has been OK. It has been fermenting since last
saturday night. Fermentation started an hour after pitching and it has
been bubbling without interruption since then. I will rack it to the
secondary as soon as bubbling stops.
I have purchase a plastic carboy (LDPE-low density poly ethylene) and
will probably prepare my first batch of beer next week. I will use an
extract I could find here and the recipe that D. Burley mailed me a
couple of weeks ago. Hopefully, everything will be fine. I will use
plastic for the primary and glass for the secondary.
I have a couple of question though. Is there any chance to have an
infection with C. botulinum? I am concerned about the possibility that
people who drink my beer could get botulismn. What should I do to
minimize the chance to get an infection from this microbe or any other in
my beer? How would I recognize it?
I have another question. The bleach that you all use to sanitize your
carboys, does it contain chlorine or not? I sanitize with a product that
contains chlorine (HClO - sodium hypochloride) and also used another
product which contains ammonia. I rinsed with tap water several times until
there is no signs of these products. Did I work correctly? I am concern
that the chlorine could give some strange flavor to the mead.
I also need the dimensions for a copper immersion wort chiller (3/8" or
1/4" or 1/2" internal diameter) which allows me to chill aproximately 6
gallons in a standard time (say 15 minutes). Any suggestions. I worked on
it and calculated that I would need aproximately 10 feet of copper
tubing. Am I correct? I will use tap water in the coils and will immerse
it in pot.
Thanks in advance for your suggestions.

Subject: unplanted hop rhizomes
I've commited a sin!
I obtained about a dozen hop rhizomes last spring that I was to plant
along a fence that never got built. The rhizomes have been sitting in the
fridge ever since.
My question to the green thumbs out there is:
What should I do with the rhizomes?
Should I:
A. plant them in small pots until they start to shoot in spring
B. leave them in the fridge and plant them in the spring
C. give up all hope and purchase fresh rhizomes in the spring
There are still shoots on some of the rhizomes that been hibernating.
There's some white garden mold/fungus that's lightly gathering around a
few of them.
Thanks for any input!!

Subject: Glass Vs. Plastic Thing
Loathe as I am to wade into the whole controversy about glass vs.
plastic... I would offer a few observations. 1.) In 25 years of
off-and-on homebrewing I have NEVER used anything but plastic. We are
talking at a fair guess, several HUNDRED homebrews. In that time, I have
NEVER had a brew that suffered ANY of the multitude of sins that are
laid at the doorstep of plastic. Anecdotal, yes, but I offer it as
empirical evidence. I think you can safely say it is of some value as a
statistical baseline. Now that is not to say that I have had every beer
come out perfect. I've made plenty of damn fool mistakes (Iodine
flavored beer (from not rinsing out the too-strong idophor solution)and
had a few "experiments" go south... (The notorious Ovaltine beer, for
example)but never any oxidized beer or any abundance of aldehydes, and
I've never heard in real life of such problems arising where the blame
could not CLEARLY be laid to poor sanitation or other fault. I'm sorry,
and i mean no disrespect, but in my experience, it just doesn't happen.
I speak here largely of polyethylene, but it should also apply, even
more so to polycarbonate (plastic carboys) because of their tighter
molecular structure. I have never used vinyl for anything but tubing and
because of the large amount of volatiles emitted by them, I would avoid
their use for fermenters, etc. But as regards polyethylene, I am totally
comfortable in their use because of personal experience, and because of
a lengthy conversation I had on the subject with a Phillips
petrochemical engineer who helped to manufacture polyethylene at their
Odessa, Texas plant. he told me that the possibility of oxygen transfer
through even low density poly was extremely unlikely, because of poly's
crystalline structure, which he said had high resistance to penetration
by water vapor and gasses. "Think about it," he told me. "If poly was
that penatrable to oxygen, there would be oxidized milk, oxidized food,
all kinds of problems. It just doesn't happen. Why do you think everyone
is switching from glass to plastic? Because plastic is cheaper, lighter
and it works." He also pointed out that polyethylene is the PREFERED
material for lab work and storage of highly reactive substances
precisely because it is inert and resistant to oxygen transter. Check to
see what the ONLY approved transfer containers for items like nitric and
flouric acid. Poly. Oh yes... If you drop a poly container of flouric
acid on the floor, what happens? It bounces. Drop a glass beaker... Hit
the decontam shower and call the HAZMAT hotline. To conclude, I have for
several years used five gallon poly containers I get free from
restaraunts (They use em to ship liquid shortning for french Fries) for
both primary and secondary fermenters. They are easy to put spigots on,
easy to drill caps for fermentation locks, and a thorough cleaning with
commercial restaurant de-greaser and VERY hot water gets em totally
grease free in short order. I use em a couple of times and toss em out
(They do ding, and I want to avoid leaks.) because they are so cheap. If
I have an espcially messy trubby brew, I don't scrub, I toss. Ease of
cleaning? Tell me about it. Again. I mean no disrespect by this, and I
do not claim to be the final word here. I am not an organic chemist,
just a homebrewer who knows what has worked for me. Nuff said.

Subject: new address complexities
Dear Mike:
I just subscribed to the HBD to my new email address. Why? Because on
Tuesday morning this past week, my university officials decided, without
prior warning, to cut me off from server access. My homepage files and my
email account were seized and placed under lock and key. I have no idea if
the account has been accepting new messages or what, because the university
won't let me know anything at all. Obviously, this is somewhat frustrating.
Also, since my comp and lit course syllabus was online, my students
couldn't find their assignments and I had to (gasp) use paper and rewrite
everything for the past two and future two weeks. Ergh.
Anyways, if you could possibly cancel the subscription I had to the
address: matthew.t.apple.1@nd.edu -- I would greatly appreciate it. I
can't figure out how else to cancel a subscription to an address I no
longer control.
So, my new address is mapple@skyenet.net, and my new brew (the first since
late May!) is a sort of nutty brown ale kinda thingey with LOTS of hops. I
used a yeast starter for the first time, and the fermentation began less
than 12 hours after innoculation. After about a day and a half the yeast
kind of pooped out, so I'm debating whether I should use another dry yeast
packet when I siphon the beer to the secondary. I've experienced some
fairly weak brews the past couple of batches, and I want to avoid that.
Thanks for all your help.

Subject: traveling beer
HBDers,
Just one more datapoint on traveling by air with beer. I was
visiting a friend in San Francisco and wanted to bring homebrew. I called
the airline I was flying (Continental....no afffiliation and I actually
didn't like the flight much anyway) to ask if it was ok. They said no
problem and I took it in my carry-on luggage. It went through the x-ray
machine.....and the operator made a comment about me having a happy
flight. So, my point is that this airline......Continental.....had no
problems with me carrying beer with me, even when I made sure they knew I
was taking it with me.
Murphy's law says your mileage will vary, but of course Murphy
hasn't been batting so well as evidenced by that dropped yet not busted
carboy.

Subject: RIMS Question: Lautering
A question for all you experienced RIMS'ers out there: How do you handle
sparging? I just sampled my first batch on the new RIMS and was shocked at
the astringency of this batch. This was one of my standard recipes so I am
sure the problem relates to inexperience with my new system. This was a 5
gallon batch. I mashed in at 135F adjusted ph to 5.2 by adding 2 tsp chalk
(for some reason pre-boiling my brew water REALLY drops the ph of the water)
and held a 30 minute rest. Ramped to 148F for a 40 minute rest then to 158F
for 30 minutes. I mashed out at 168F and held this temp for 10 minutes
before beginning my sparge. I add nothing to my sparge water (since it is
low ph to begin with). Here is where I may have messed up - during
lautering, I continued recirculating the mash while diverting a small
portion to the brewpot rather than just allowing the entire mash runoff to
flow slowly to the kettle. I periodically pumped more sparge water into the
mash tun to keep the level above the grain bed. I am wondering if the
recirculation during lautering, particularly late during the process was,
in effect, over sparging? I did not take gravity readings or ph readings of
the run off, since in the 20 or so times I have brewed this recipe with my
old system, I just collected a fixed amount of wort for the boil and never
had any astringency problem. The only change to my recipe this time was the
use of Great Western 2 Row as opposed to my usual Breiss 2 Row, but I doubt
that would account for the problems. Any advice appreciated!

collective homebrew conscience:
i have been in maryland for the past two weeks, and away from the forum. man,
this stuff piles up fast.
just a recent experience to share: i bought a 6 of oregon pale ale the other
night. took it to my hotel room, poured the first bottle, and , ugh! a
bunch of nasty trub-looking crap started coming out. inspection of the
other 5 revealed what looked like proteinaceous material in the bottoms of
each of them. and quite a bit. so i took the beer back and got an exchange.
i noticed also that the expiration date was april of this year.
i've commented before about the importance of freshness and shelf life, and
this experience only reaffirms the notion in my mind.
anheuser may be using this "born on" dating as a marketing tool, but i think
i would actually prefer to know when a beer was bottled than not have that
information.
of course we homebrewers have the best situation in this regard.

Subject: Filtering Question !?
Hello all,
I filtered my first batch of beer last night using my new filter.
Although the beer turned out great, I was wondering something.
I racked my beer from the fermenter into a keg, hooked up keg taps
to both "OUT's" on the kegs, and hooked up the filter between the
two. I then applied what I thought would be an adequate PSI to
push the beer through, 5psi. It started veeeery slowly, so I started
inching up the psi. I ended up pushing the beer through using about
25psi, and although it was foaming, the foam settled out in the
final keg and everything was OK. The entire process took about 2
hours, however, and although I enjoyed the time to drink a few
brews, it was rather slow.
What psi does everyone else use? Would chilling the beer before
filtering help? What other processes would help/do people do?
Thanks for any info.

Subject: Carbonater Caps
I just bit the bullet and bought a carbonater cap a week ago, and I've
got to admit while it's pricey as hell, I wish *I* had thought of it.
I want to bottle part of a batch in 20 oz PET Coke bottles (thinking,
wow... an imperial pint, ready to go, in minutes...) My experiments with
force carbonating in these has been pretty favorable so far; I've
carbonated just about every liquid I can get in the refrigerator.
So here's the question: Once you carbonate one of these Coke bottles,
are you stuck with leaving the $12 carbonater cap on there until you
drink it, or can you take it off, replace it with the regular bottle cap,
and then do the next one?
How about if you chill them to near freezing first to increase the gas
solubility, and then the pressure that you lose switching caps wouldn't
be so great at a normal refrigerated temperature? Any experience in this
regard?
Carbonating one at a time as they're consumed seems kind of a pain in the
ass, and I'm *way* too cheap to buy enough Carbonater caps to do a whole
batch at once. And no, I'm not too interested in using 2 liter PET
bottles, although I might have to reconsider.
Thanks,

Subject: plastic
Hi.
I don't want this to go into one of these never-ending threads that bore
everybody to death, but there are a couple of questions that need answering.
>From Guy Gregory..
>The tone of the conversation thus far suggests to me that we US'ers are
>overafraid of oxidation reactions and scratching of proper plastic, and I
>think the "Oz"zies are overconcerned about the danger of glass carboys.
Aussies scared of anything? Hah!
I have both types and use both. I mentioned a friend who had a very nasty
accident with a glass carboy. This happened, but it just means you have to
be careful (which I am). I can assure you the danger thing is not a real
issue for us.
The main reasons I prefer plastic were posted previously. My 60l glass
carboy does not fit in *any* fridge I own. Very inconvenient. It is a
practical thing and the beer quality does not appear to suffer by using
plastic.
> Lets relax, OK? Brew with what ya got. What kinda plastic are you using,
>mates? It does make a difference.
The plastic we use is HDPE (which *was* mentioned in my previous post).
Remember this thread started because there was an ignorant assertion made
that use of plastic in brewing leads to stale and/or infected beer. This is
a recurring issue on the HBD that needed correcting. That's it. I'm certain
that even my rantings will make zero difference, and we'll still see this
type of statement again in a few months.
and from Michael Owings..
> Andy, do you feel the extra head space in the bucket
>poses a problem for secondary use? I gather the HDP cubes you mention
>are somewhat more airtight than the buckets (assuming I'm thinking of
>the right HDP cubes).
>
The cubes we have here are about 20l with a screw on lid that is about 8cm
in diameter. The plastic thickness is 3mm or so. They are pretty much
airtight, and you can throw them around without worrying about beer
splashing everywhere. I fill them to the brim to give minimal headspace.
Being stackable means they take up little floor area.
A normal primary bucket could be used, but the ones we get here don't seal
very well, which would concern me. The additional headspace would not be a
problem if you rack a little earlier than usual, while the beer was still
active. CO2 could also be used from your gas bottle to purge the thing
before use.
I'd be surprised if the cubes were not available in the USA. They are used
to carry water. Try a camping shop.

The real problem here, between the Ozzies and the Yank's is that
plastic in the Northern hemisphere doesn't react to oxygen permeability the
same way as plastic in the Southern hemisphere....This has been well
documented by Doctor Greg Waite of the "Cane Toad Institute" of Northern
Queensland in his treatise, "Cane Toads and Compact Disc's.....What's the
Deal?," published by the University of Queensland, Saint Lucia, Qld, and
co-authored by Joh Bjelke-Peterson. And the same thing that applies to
plastic CD's applies to fermentation vessels.....
So, read and learn....

And there you have it!!!!
In Australia, the plastic fermenting pails are ever so gently turned
in a lathe with decreasing grades of ever finer grit paper, such that there
is never a scratch evident to harbour bacteria!!! And everyone knows that in
the Southern hemisphere, the O2 concentration is less than in the Northern
Hemisphere, (less cars, and trees, you know!)...therefore less available O2
to permeate!!! (except in Melbourne!!)
Seppo's could learn much from this mob!!!
Hoo-ray!

Subject: fruit syrups
1) has anyone else brewed with fruit concentrates?? last time i used one,
within five or ten days at room tempature it tasted like sour fruit. not
just once but two or three times i have had similar experiences. when i
used real fruit it never has been a problem. my question: what is this?
i have one theory. i think that the syrup is rich in oxygen when it
arrives. whenever i've added it, it has been in the secondary. what
spawned this was papazian's association of oxidation with uric acid. wht
does anyone think.
Cheers to all,

Subject: Apples, Oranges, Hammers and Screwdrivers
From: Alex Santic <alex@brainlink.com>
>As A.K. pointed out, heat loss can be a problem using the EasyMasher with a
typical brew kettle. I've done one batch with it so far and was
pleased with how well it went, but maintaining a given temperature as
well as keeping it even throughout the mash was difficult.
Well, it sounds to me like you are trying to turn an apple into
an orange.
If one chooses to use a kettle for mashing, we assume the one does so in
order to get better control of the process, viz. any temp at any point
during the mash. The price one pays for this capability is gas (heat)
and the need to stir.
If you do not wish to be bothered with the addition of heat and stirring,
you should put the EM in an insulated cooler and just be satisfied with
simple infusion mashes. But to try to turn a kettle into an insulated
cooler does not seem to make much sense.
>I used almost-boiling water for the sparge and was never in danger of
overheating the mash.
Contrary to popular opinion, the temperature of the sparge water is
irrelevant. All that matters is the mash temp as you have noted. If
it takes boiling water to get it right, who cares?
>I probably will use a more typical sparge water temperature once I come up
with a solution for insulating the kettle.
A cooler would be a lot easier.
>Another potential heat-loss problem occurred to me as I was working. Itseems
plausible that it would be difficult to get a dextrinous wort, or
at least strike an intended balance, with a lot of cool areas in the
mash. The remaining beta-amylase might make short work of the dextrins
being created in the hotter parts of the mash.
Me thinks the gentleman worries too much. Do you think there would be
no stratification if it were insulated? The solution is to stir.
>Finally, the only solution to heat loss is to add heat, and when you dothat
you have to stir pretty well to get it distributed evenly.
Folks have been doing that since the dawn of brewing. That is, unless
they use insulated coolers.
> All the stirring actually aggravates the heat loss...
Yes but if you add heat, who cares?
> and I'm afraid it results in a good deal of aeration as well.
Rubbish. I have a continuous rotary mixer on my tun and so do many
big time brewers and aeration is not a problem at normal mixing
rates.
>Insulating the kettle may be a very important issue with the
Easymasher,otherwise it's a very useful device.
Again, you are trying to pound a nail with a screwdriver.

Subject: Goodbye and Thanks for the Beer!
Bye All,
I would like to sincerly thank all of you who have contributed to my
understanding of brewing over the last couple of years. It has been
stimulating and amazing at times.
However life is too short to read all the HBD's, (I'm 12 behind) so I can no
longer participate in discussions and threads. The digest is obviously
fermenting like a train.
I will post relevant summarys of my research occasionally, but replies will
have to be by email as I no longer subscribe.

Subject: quick fermenter?
Hello,
I'd like to thank everyone who helped me last week with my first
all-grain brew! I ran in to the exact opposite problem as I thought
I would have ... I had to get rid of heat! The mash was a little
hotter than I would have liked (.75 qts/lb @ 190F water) at about
165ish degrees after 15 minutes. I went with a lower volume
strike-in, assuming that I would have to add some heated water
later due to temp drop (I use buckets). Well, there was virtually
no drop without leaving the lid off!!
Anyways, I ended up with a little over 2 gallons ( i was shooting
for between 2 1/2 and 3) at 1.052 OG. Now the wierd part is that
I pitched about 8oz of yeast slurry (yeast started about 3 days
prior) and within 3 hours there was a serious storm going on inside
my carboy! I was psyched to see how fast fermentation began when
pitching a larger volume of yeast. However, after about 12 hours,
it has stopped. It looks done. 3/4 of an inch of sediment and
hardly any bubbles at all.
Anyways, thanks again to all who helped. If anyone has an idea about
what has happened or maybe some pointers for my next batch (i'll
probably go with 1 qt/lb @ 170 degrees) that would be great!

Subject: Killer-chiller
KennyEddy argues when discussing the killer chiller
that several flat spirals mounted horizontaly
one above the other in the wort
chill better because they overcome the problem of
temperature gradients forming in wort chilled with one
horizontal spiral and no agitation.
If that is the case would one flat spiral suspended verticaly
in the wort chill significantly better (faster) than the common
single flat spiral used horizontaly?.
If using the spiral in the vertical configuration is an improvement
it would be certainly simpler and cheaper to construct than the
four tier killer chiller.
Thoughts??
