Subject: Moldy fridge
Hello HBD universe! I have resubscribed again after several years of
less than enough time for brewing (Shame on me).
Anyway, glad to see that Pat and company are still taking care of business.
Speaking of business, I have a wierd issue. I have had a keggerator for at
least 10 years. A few weeks ago when removing a dead soldier, I found what
looks like mold spots all over the inside - including on the beer and
CO2 tubing and the top of the keg. Where did it come from? I had no liquid,
no leaks, no nothing!
Even more important, does anyone have a suggestion for cleaning/sanitizing
the fridge so this doesn't recurr and spoil my beer? Is there any way to
somehow "fumigate" to get into all the nooks and crannies (like inside the
evaporator coil, tap tower, etc)?
I will surely remove the tubing and disassemble and clean and santize
the beer and gas fittings.
Thanks for your suggestions!
Happy Brewing

Fred,
I don't know what HSI is, but I have experienced this on multiple
occasions with different batches of hops. It's not just me but
obviously it's not everyone or nobody would ever brew with Galena.
It's just a factoid that was rattling around in my head that the two
Galena suggestions prompted me to post about. Or, as they say around
here, YMMV.

Subject: rice
Paul, et al;
I have used rice for several years, but usually the flaked rice that has
already been galatinized. I wonder: what are your views on the final product
with rice versus corn? I have also used flaked corn, and, for some reason I
prefer the final flavor of corn in a CAP than rice. I am not quite sure what
words to put on the flavor difference, perhaps slightly "sweeter" at the end,
ie not as dry with rice.
I wonder, Jeff, and others who do this regularly: what are the final taste
differences that you perceive with rice as opposed to corn?

HI Matt:
I believe that the Brewing book "Brewing" by Lewis and Young
is for the buck the best you can get.
The whole book is practical and scientific at the same time.

Subject: Diacetyl part 1 A
So,what can be done to have the proper level of diacetyl:
*Very vigourus boil, never less than 75 minutes.
I don't care if you hear the "60 minutes" boil, don't believe it !!!!!!!!
*If necessary, get some yeast nutrients, they help altimes giving your yeast
enough nutrients, or let's say, the more proper nutrients, such as Zink.
*If needed, start your fermentation with a warmer temperature (especially
Lagers),
to increase the yeast metabolism, which in return will have a Diacetyl
reduction.

Subject: Diacetyl
Here I am again:
Diacetyl is also caused by infections, bacterial infections, mostly by SARCINA.
In most cases I found that Diacety caused by infections could be traced back
to the end of the fermentation and most times associated by the yeast used.
Eliminate a delay in start of fermentation. Allow yeast to properly
start to work by increasing your pitching temperature, avoid over-oxygenation
your wort,
and most of all: KEEP IT CLEAN AND SANITARY.

Subject: re: Ancient History Revealed!
Pat & all,
I am also a long time reader of the HBD. In recent years
I've hardly posted at all, but I look for the HBD in my email
every morning. The things many of you have said in regards
to Pat's post resonate with me, they are in accord with my own thoughts.
Like Jeff, I am a member of the AHA Governing Committee.
When I first ran for election I was fairly unknown outside Florida
& I credit the HBD community with my election. The HBD
hosted my club website (Hogtown Brewers) for many years.
I've also made & later met many friends through the HBD.
It would be a shame if the HBD were to go away.
It's been an important part of our lives for a long time. We
owe Pat & the other janitors a huge debt for their endeavors.
I have emailed Gary Glass and the AHA GC in regards to
the HBD situation & suggested that the HBD could be mirrored
on the AHA server. I believe that Gary and/or Tim Sloan
(the AHA IT guy) should already be in contact with Pat on this.
The AHA brewing list, TechTalk, has grown tremendously over
the last several years. This growth has been at the same time as traffic
on the HBD has slacked off. While I'm gratified that TechTalk
has grown into an active & useful resource, it is only available
to AHA members (though I haven't been a regular poster there
either). I truly hope that the growth of TechTalk hasn't been the
cause of the HBD's slowdown. I suspect that it is one of a number
of factors. At anyrate, like all of us, I hope that HBD can continue
for many years.
Pat,
Without having a sponsor for HBD, how much do you need
each year to keep the HBD afloat? I will send a check. I used
to do that regularly, and have my club do that as well. I will
make a donation to the Server Fund again. Others have said
they will as well. Maybe we can turn this around ..... both
financially & with increased traffic.

I tried this yeast a few months ago and was very disappointed with it. I
started it at 68F and let it ramp up to 82F as I have done for the wlp 565
in the past. the resulting beer had a strange flavor. it wasn't nearly
as good as 565. it was sort of sour and somewhat off-putting. it tasted
like it had a slight infection, but i doubt that it did. as for
attentuation, mine was a bit disappointing. maybe it didn't like the hot
temps? it seemed like it slowed down as i pushed it past about 78F. it
was about 79% AA for a 1.061 beer with about 7 points worth of corn sugar.
i would expect 80-85% AA!
Darrell, what were your fermentation temps.

Subject: Samichlaus
There have been questions about this great beer,
and several correct answers.
In reference to the earlier mention of the beer
not being brewed since 1986, I think someone is
getting the information off the "new" HELLES
that was released last month. That label claims
it is the first time since 1986 that the helles
has been brewed.
The dark Samichlaus was dropped for a few years
in the late 90s, but I think it was only gone <4
years. I doubt the reference on the label to the
first brewing of the helles since 1986. I don't
have any left, but I am certain I remember
having had some of the helles from the early 90s
when Hurlimann was brewing.

It doesn't take much steam, but it takes it at the right time. What I
do is put a large cast iron skillet in on the bottom rack (with a
sealed burner, you could put it on the floor, maybe?) when I preheat
the oven. You want something that has a lot of thermal mass, and
won't warp. When I put the bread in, I toss a couple ice cubes in the
skillet. That gives steam as the ice melts and the water flashes off
the skillet. That's much easier and safer than trying to pour boiling
water into the oven, which is what I see in cookbooks.
My oven is a pretty crappy one, and doesn't have much thermal mass.
When I open the oven, the temperature drops, and takes a long time to
recover. So, I keep a baking stone in it when baking bread, even if
i'm baking in loaf pans. For stuff that gets baked at fairly high
temperature, I'll preheat the oven at 550F (higest temperature
setting) and turn it to what I'm baking at (400 or 450, usually) when
I'm about to put things in it.
Convection modes can be use to make great bread, but cooking times and
often temperature have to be adjusted, both down. I have little
experience with it, though.

Subject: no knead
Hi Mike
it seems we have brewers here, who know how to bake as well ;-)
I will give you my observations from my 15 years of homebaking.
If you think of the gluten-protein like a spiral spring, that you
stretch during kneading, folding it just gives it some more tension. If
you knead it sufficiently, folding is not necessary. A single fold
doesn't hurt 30 to 60 minutes after kneading. The less you knead, the
more folds are appropriate. Although i didn't try no knead breads, my
boss started to do it after he was in Ireland for some golfing and
didn't get decent bread in closeby stores. He only mixed the ingredients
in the evening, and baked the bread in the morning. The bread we both
like to make, is made from a very moist dough. (80% water)
This dough is so moist, you can't fold it. I let it "flow" out of the
proofing bowl, and shape it with my hands dipped in cold water. Then i
have to put it into the oven quickly, otherwise it would flow too wide.
What is really important, is a hot oven. I have two electric ovens and a
wood fired clay oven i built myself last summer. I heat it up to 535F
with a "pizza stone", then let it fall to 425F during the bake. With
such a moist dough, you don't really have to care much for steam. They
get a wonderfull oven spring, without even ripping. (remarkable given
the fact, that i can't give it a final proof after shaping)
The oven i use is rather small, but i can heat it up to 572F. My main
oven has a built in steam generator, but i can only heat it up to 450F.
I use it for croissants and braided breads, that have butter and eggs in
the dough. Or generally for less moist doughs. I'm just firing up my
clay oven to bake some "Flammkuchen" with my brew buddies this
afternoon. I bake pizza and flammkuchen in the range of 670F in 5 or so
minutes.
If you like to see it, go to instructables.com and search for "pizza
oven"... (it's a really cool site for us tinkerers anyway, although this
was rather hard work, than tinkering)
If you like to inject steam, put a heavy skillet on the oven floor, let
it heat up, then throw some ice cubes or not too much water in, just
before you put the dough in(you want it to boil instantly). But this
won't help much in terms of crust building. The high humidity helps in
delaying the building of a crust, since it will condense on the "cold"
dough and prevent the building of a crust during the oven spring. So
after about 4-5 minutes into the bake, you need to vent the steam off,
if you like a crunchy crust. I vent it 3-4 times more during the bake
and get a really crunchy crust. The most important thing for a good
crust is a relatively high moisture content in the dough and a high oven
temp in the beginning of the bake. With a high moisture content, i mean
in the range from 60 to 80% water by weight to the weight of the four.
As a next important thing, the amount of yeast given in most receipes or
on yeast packages is about 4 times too high. Especially if you give it a
long proofing, 1-2% of the weight of the flour is more than adequate.
The proofing button in your oven will bring it into the range from 77F
to 95F. I seldom use it, or would you ferment a lager at 70F? I like to
have a long ferment, or i use a 40% preferment.
Otherwise, i have one hint left: Do bake, it's very rewarding. It's so
contagious, my brew buddies started to bake as well. (it's fun having
your selfmade pretzels with a nice brew and a weisswurst)
I still have lots to learn, but it's worth it and it's fun.
I recently bought a bread baking machine, i don't use it for baking(no
crust and ugly shape...), but it's cool for having a dough ready kneaded
and proofed in the morning. I don't have to get up at 4 in the morning
to bake a bread at 8 o'clock. If you intend to buy one, take a "Unold"
brand. As far as i know, it's the only one that has a "free program"
feature. That means besides the fixed programs, you really can program
the kneading, proofing, degassing and if you really like, bake it in
this machine. I have bought a panasonic, it's of good quality but lacks
the "free" programmability. If i want to make a "timed" dough, i have to
use the bake program and zap the power before it starts to bake.
Cheers and crunch

Subject: Incredible head foam stability
I was on was on a plane the other day with the usual poor selection
of beers. I had a Michelob (or maybe it was a Miller Genuine Draft)
and I was impressed with the incredibly persistent head on this beer.
The foam on this was so thick at the crown of the head that I could
have spread it on toast.
Considering the low malt and hopping level of this beer, I assume the
brewer has added something to produce this meringue-like foam. I know
of some agents, Profoam for one, that are used for improving head
retention. Does anyone know what Anheuser-Busch (or Miller) is using
in this beer?

Subject: Foundation Space
While reading in the Northern Brewer catalogue about false bottoms it is
mentioned that minimizing the distance below the false bottom will increase
efficiency. I am trying to understand why. I use a converted Sanke and my
false bottom rests on a shoulder of the keg where it transitions from
cylinder to bottom dome. This makes it about 3 inches above the bottom of
the keg. I have installed a bottom drain in the keg.
When I mash I account for the water below the false bottom and add that
volume to the total mash volume (typically 1 qt. per lb). When I sparge I
keep sparging until I collect what I need in the boiler. I have not run
into any issues with low gravity runnings. I typically get 75 - 80%
efficiency. Is the foundation space BS with my system?
