I would think that carbon monoxide wouldn't be a problem as long as the burner
is properly adjusted. After all, running your kitchen stove for hours at a
time won't kill you. Large stores and warehouses frequently power their
forklifts, floor-cleaning equipment, etc. with propane when they're operated
indoors.
My understanding of the matter is that you don't want yellow flame. That
indicates a too-rich fuel/air mixture, which produces soot and carbon monoxide.
If you lean out the mixture so that you get a consistent blue flame, you
should get little or no carbon monoxide.
I made a couple or three batches indoors with a turkey fryer, and I'm still
here. :-) It sent the indoor temperature skyrocketing into the low to mid-80s,
though, and I get piss-poor ventilation when I open the one window that I have
here.
I ended up going electric with my brewing:

I get a shorter warmup time and a stronger boil than I ever did with gas, which
leads to a better hot break. Between that and a better cold break from an
improved cooling setup after the boil (circulating tap water through an
immersion chiller to drop the temperature down to 100-110, then switching to
ice water recirculated with a swamp-cooler pump to drop it the rest of the
way), I'm making better beer than before. Because I'm dumping heat directly
into the wort (instead of onto a pot and then into the wort), heating
efficiency is greatly improved, as indicated by the indoor temperature barely
nudging upward from its usual setting in the mid-70s.
This also ends up being a safer setup for indoor use. It does away with the
potential open-flame and indoor-propane-tank hazards, and stopping a potential
boilover is as easy as flipping a switch.
There's usually more than one way to flay a feline in this hobby, but after
using the heatsticks, I don't think I'd want to go back to using gas unless I
had no other choice.

Subject: Hops and anticancer
Brewsters:
An interesting bit of health news from Food Navigator - USA
- ---------------------------
Hops rich in anti-cancer compounds
11/18/2005- New research into a flavonoid compound found only in hops shows
that it may help prevent cancer if a method to improve its absorption in the
body can be found.
The anti-cancer activity of xanthohumol was first discovered around 10 years
ago by a team at Oregon State University in the US.
But although some brewers are now marketing products enriched in the
compound, such as Germany's Xam, the US researchers say beer is unlikely to
offer any anti-cancer benefits.
Fred Stevens, based at Oregon's Linus Pauling Institute, told
NutraIngredients.com: "Even with higher levels of xanthuomol in beer it is
very hard to get the levels we tested in cell cultures into the
bloodstream."
"Absorption is very limited and even if it was all absorbed, there is very
active metabolism. The xanthuomol is mostly glucaronated."
Nevertheless, Stevens believes the findings are promising enough to merit
further research, and also to look at different methods of consumption.
"If you put the compound in a capsule, that's a whole different story," he
said.
A number of studies in cell culture and in animal models have demonstrated
the flavonoid's ability to kill cancer cells, including a recent study
presented at the AACR meeting in Baltimore earlier this month.
The poster presentation described how xanthohumol killed prostate cancer in
cells and animal models through apoptosis.
In previous work looking at breast, ovarian and colon cancer cells, the
researchers have also identified other mechanisms of anti-cancer action.
Xanthohumol, and other related flavonoids in hops, appear to inhibit the
family of enzymes commonly called cytochromes P450 that can activate the
cancer process.
It also induces activity in a 'quinone reductase' process that helps the
body detoxify carcinogens.
Other research groups have picked up on the research and are looking further
at the compound.
"The published literature and research on its properties are just exploding
at this point, and there's a great deal of interest," added Stevens.
It is thought that hops might be produced or genetically engineered to have
higher levels of xanthohumol, specifically to take advantage of its
anti-cancer properties.
Some beers already have higher levels of these compounds than others. Lager
and pilsner beers have fairly low levels of these compounds, but some
porter, stout and ale brews have much higher levels.
Ideally, researchers say, cancer chemoprevention is targeted at the early
stages of cancer development and prevented by long-term exposure to
non-toxic nutrients, food supplements or drugs that prevent the formation of
cancers.
With its broad spectrum activity, presence in food products, and ability to
inhibit cancer at low concentrations, xanthohumol might be a good candidate
for that list.
Meanwhile the US government's National Institutes of Health is funding a
study to test the potential for another hops compound, structurally very
similar but with oestrogenic properties, to help menopause symptoms.
- --------------------------
And in this last statement I am reminded of the joke about the effect of too
many beers on a bunch of guys and them becoming more feminine and now we
have scientific evidence - it must be the hops. {8^)
Keep on Brewin'

Subject: Lager darkened in keg
Brewed a basic BudMillerCoors American Lager that I've done a few times
before. Everything was fine going into the keg - golden color and the taste
I expected. After 3 weeks lagering in my kegerator I sampled it this evening
and the beer has noticeably darkened and tastes very different. Hard to
describe - bitterness going down but with a sickly sweet aftertaste.
Any ideas on what could have happened?

Subject: Blogging Homebrewers
Some people have mentioned that the number of posts on HBD has diminished
over the years, though readership, I imagine, is still pretty high. One of
the reasons for this, I think, is that the Internet is a bigger place, and
there are more places now where people talk about brewing. Discussions are
somewhat scattered.
I know for me that I tend to write stuff in my brewing blog and I also read
a lot of brewing blogs. Since HBD, in my opinion, is still the center of
the brewing universe, I thought I'd post about some of the blogs I read.
John, of The Musings of Fish, is a new homebrewer who has brewed with his
friend Matt of The Prancing Tarantula. He is working on building his brewery
at home, but wonders if his kitchen is big enough. John's blog is not
strictly about brewing; it is about his life, which includes occasional
posts about brewing.
http://fishmuse.blogspot.com/
Matt, on the other hand, of the afore mentioned The Prancing Tarantula, is
an experienced brewer, who also makes wine and other things. He is toying
with the idea of going all-grain. Matt's blog has a high percentage of
posts about brewing.
http://prantran.blogspot.com/
The Marcobrau Brew Journal is a very tight blog where the writer sticks to
his guns, blogging about batches he's done, his process, tasting notes, and
so on. Like clockwork, you know where he is in the process of doing each
batch. Most of the posts on this blog are about brewing.
http://marcobrau.blogspot.com/
SudsPundit is a group of blogging brewers, all writing about brewing on one
site. One of them in particular, Brian, is from Tucson, just like me. Like
the Marcobrau Brew Journal, mentioned above, it is a very tight blog. They
rarely deviate from the subject of brewing.
http://sudspundit.blogspot.com/
The last one listed here is Bad Ben's Ramblings. Ben is a very experienced
homebrewer who has done strictly all-grain brewing for 18 years. I was very
impressed by his massive, home built, conical fermenter, which he has
pictured on his site. Ben's blog, like John's above, is not just about
brewing; it is about his life, which includes posts about brewing, and other
things, like running.
http://badbenkc.blogspot.com/
I am curious as to how many other HBD readers also have blogs where they
post brewing discussions.
