Now the microbiologist/homebrewer/mead maker/new dad/entrepreneur/and general well-meaning
PITA enters the discussion... :)
Hi Dave et. al.,
In a nutshell.... excellent reply to Carole from David Berg. You could dress up as a
microbiologist tonight and even justify begging for some candy!! :P But watch out for
those nasty cavity-causing bacteria that live in the oral regions....they do like the
sugars found in Halloween goodies!
It is very true that known disease-causing microorganisms are not found in finished beer.
Even Belgian Lambic's, weird as they may be, are not beverages that would make one
nervous about getting sick. Cleaning out your digestive system and taking care of any
fecal constipation.... that may or may not occur..... ok, enough about that!!
Beer....even "Spoiled" beer is an interesting beverage. It also is a growth
substrate for a few organisms. Very few, actually. Dave's mention of low pH
(acidity), alcohol content, and presence of hop flower chemicals is right on target for
providing reasons that homebrew (or bad commercial beer, for that matter) is not a
worrisome beverage for us consumers/producers.
FYI, hop tea has been used as a beverage for a number of reasons besides providing hop
character to beer. Including usage as a sleep aid (well, that is somewhat debatable...but
go check out the history of hop usage), and as an aid for "bellyaches" (more
plausible). Hop analysis has shown many different types of interesting organic compounds,
some of which are very effective antimicrobials. OK, time to step away from the soapbox
again....
Charlie P. is not necessarily the world's leading authority on microbes and their
relationship to beer/mead/other quaffable stuff. But, he does have a basic grasp of what
is important. So do people like Dr. Michael Lewis and Greg Noonan and, may God rest his
soul, Dr. George Fix. What it comes down to is this, IMNSHOP..... clean your brew
equipment as best you can.... use good water, good grain or malt extract, use good, fresh
hops, and add lots of Saccharomyces cerevisiae (yeast), and then sit back and observe one
of nature's miracles take place....then relax, don't worry and drink your
homebrew!!
Just my more-than two cents worth..... :P
Best wishes to all for a Hoppy and safe Halloween!!

I'm no microbiologist, but I've thought of
playing one on TV.
Pathogens will not grow in beer due to the following reasons:
1. Acidity of beer
2. Alcohol
3. Hops
Also, yeast is pretty agressive in its fight for a food source, so it is
often hard for bacteria to get its foot in the door even.
We're not saying that yeast or bacteria can't grow in beer--just none
that will kill you.

I know I'm extrapolating this to another level, but I'm amazed (and
disappointed) about "Charly P." saying no pathogens survive in beer.
If
this were so, beer would be used to disinfect things like surgical
instruments. I'm not so sure I'd like my obstetrician or brain
surgeon
using beer for disinfection. (just hand that beer to ME). If YEAST
can
grow in beer, I'm sure there's some nasty bug that can kill you that
can
grow in beer. Any microbiologists care to set us straight? ;->

I am curious as to why contamination in wine can be
deadly whereas not so in beer? Does the acidity have
anything to do with it?

Someone said "sanitation is not as critical with
Mead and Wine" this is not my understanding. Fifteen
years ago Poison Control told me that contamination
in home-made wine was common and sometimes fatal.
Charly P. sez there are no known pathogens that
survive in beer.
