Hello all
i'm just watching the bunging of the first barrel in Munich's
Oktoberfest. (on the bavarian TV-Channel)
Hell, i'll probably go there this year again. (If you like to go, go on
a sunny weekday not too late, noon is cool, then have a Mass a
Weisswurstand and a Brezen(aka Pretzel in the US). Around 17:00 it will
get crowded on weekdays. Be shure to have a nice seating by then!)
Today we'll go to pick our hops, with my brewbuddies. Nice weather, 130
miles away from Munich.
Dave, i will try to translate the hop pruning instructions. Maybe Greg
Lehey will help a little bit, i sent him the instructions in german.
(It's called "The green leaflet" this is the german hopgrowers annual
publication)
I will send the pdf to you anyways. Since pictures say more than words.
Cheers and noamol oas. (Bavarian for one more, or another one)
Thomas

Subject: An essay on homebrewing
Inspired by some recent hbd posts that seemed like gibberish to me (and
another hbd'er), I played a joke by submitting some gibberish of my own.
I used this little program at www.EssayGenerator.com and typed in
"homebrewing". The result was posted:
http://www.hbd.org/hbd/archive/5059.html#5059-8
My apologies to the janitors.
Cheers!

Subject: Fourth SRM
I measured my Summer Weizen last night, got a pretty good result and
learned a lesson. I did the dilutions using a graduated cylinder and got
a very good fit (r=.9989) but the estimated SRM was 4.41 and the
spectrophotometer reported 6.5. Uh-oh. A look at the entire spectrum
quickly revealed what the problem was. The absorbtion at the red end was
high which is an idicator that the beer was turbid. That's why the SRM
method want's the second check reading made at 720 nm. This is a turbid
Hefe Weizen so I centrifuged it. When I returned the centrifuge tube to
vertical after pouring off the 25mL of sample for the photo I evidently
disturbed the pellet in the bottom. A quick recentrifuge of the
remaining liquid in the tube got the instrument reading down to SRM 5.1.
This is off by 0.7 SRM which is the worst agreement of the 4 we've
measured but still not bad.
Fred Johnson wrote offline asking for details on the filter being used
which suggests that he misunderstood but also suggests a possible
improvement to the method. There is no external filter. I am using the
color separation filter IN the camera. Most cameras still have 3 sensors
for R,G,and B whether they be 3 separate chips with filters in front of
them as in the case of fancier video cameras (which is what I am using)
or a Bayer mask (little tiny red, green and blue filters lain over a
single CCD chip). That's the scheme used in most still and video
cameras. Some manufacturers are producing cameras with more than 3 color
channels and, I assume, matrixing to R, G and B. I don't know whether
these would work or not. The 3 channel cameras, though, all have filters
with responses like the one whose specs I posted the other day.
Using an external filter is, however, a good idea! With a narrower
filter the response of a spectrophotomer would be better approximated
(though one problem with this is that very narrow filters don't pass
much light and you might need a really hefty source and long exposure).
Part of the beauty of this technique is that it seems pretty robust
using the camera's own filter but that doesn't mean it can't be
improved! This is because of the similarity in shape of beer spectra
(which is also why the SRM measurement does convey information about
actual color).
And that brings up another point for anyone that want's to try this.
Turn out room lights so that the only light reaching the camera lens
comes from the light table.
Cheers, A.J.

Subject: Mead
Wow, step away from the computer for a few days and all heck breaks
loose. Sorry I haven't responded to this earlier.
If you want to make a mead that will be drinkable in 6-7 weeks, here
are my comments: Go with the staggered nutrient additions that were
outlined earlier. Fast, healthy fermentation is paramount. Al did a
very good job of encapsulating that. I'd also shoot for a sweeter
mead, as it will be drinkable much sooner. 71B-1122 is the yeast.
Next, use 10-20 lbs of cherries or a berry fruit. They clear
quickly, and the big aroma, mouthfeel and body from the fruit
character masks off aromas or flavors. It may not be the crystal
clear, classic traditional that they might have had in their minds
eye, but hey, they didn't leave you a lot of options. 21- 28 days in
fermentation, rack off yeast for ~2 weeks in glass, and give it two
days in the keg or bottles.
Steven Parfitt;
Your recipes are for very low gravity meads, using a yeast that is
groomed for high gravity musts. At those finishing gravities, the
phenolic and/or higher alcohol character you are describing will take
a while to age out. All hope, however, is not lost.
If you sweeten them up, you could have a good shot at making them
enjoyably drinkable. I don't know when your fermentations ceased, but
I'd be tempted to add another couple of pounds of honey to each of
them to see if they get going again. If they do, I'd add another
four-six pounds, and a teaspoon of DAP. I'd shoot for FG
1.015-1.020 to make them palatable for the event.
So what it they don't restart? I'm hoping you have kegging gear.
Hit them with .5 tsp potassium sorbate per gallon. Wait a day. Then
sweeten them up to about 1.020, and force carbonate them in a keg.
Meads are harder to force carbonate than beers, but it can be done.
Refrigerate the keg at the serving location a couple of days ahead of
time to encourage as much clarity as you can manage.
Another suggestion: Lots of fruit character generally goes over
pretty well with a general public audience, like a wedding crowd.
You could find a source for blueberry juice concentrate, and mix that
in to taste (add small increments until you hit the level your
daughter likes) after the sorbate has done its job. That will help
hide the edges, too. If your daughter doesn't care, you can turn it
into a fruit bomb. You may think it's cheating, but those in
attendance will just think it tastes good.
On the traditional, you might want to try some pectic enzyme to see
if it will clear. I don't know why it works, but it has worked for
me in the past, it's fast (24 hours) and you don't have the risk of a
big sediment that you get from bentonite. Polyclar might be a good
alternative.
If you are dead set against tampering with the trad, I understand,
but If not, there are lots of ways you could doctor that with fruit
or spices to make it tasty by the big day. Drop a line off the
digest and we can sort that out.
I hope this helps.
Ken

Peter is right! There is an economic benefit to homebrewing. The other day I
stopped by the local mom and pop store, and picked up 2 six-packs of microbrew.
One was Magic Hat's Fat Angel, and the other was Lake Placid's Ubu. The total
bill was nearly 18 bucks!
When I got home, I punched the numbers (which I will share if anyone wishes to
see the "higher math" imbedded). When my wife got home, I told her that I
cannot afford to stop brewing. If I were to purchase all that I brewed, at
that price, I was SAVING $4,000.00 per year! I can't stop!
Economics indeed!
