protection against bacteria

Dec 25, 2004 3 Replies

Greetings, I'm an aspiring home-brewer, and the two batches I've done so far haven't quite lived up to my expectations. They seemed to have a "skunky" flavor to them, and I'm thinking it might be due to insufficient sanitization. I know one of the best ways to protect against bacterial contamination is to get the yeast active as quickly as possible, as the resulting alcohol will help kill any resident bacteria. That being said, has anyone ever tried adding a half-shot or so of grain alcohol to the wort, to provide a bit of protection until the yeast gets going? Obviously, the real solution is to sanitize everything better, but this would serve as another layer of defense. My concern is that it might stunt the yeast growth (the amount necessary to prove fatal to bacteria would also prove fatal to the yeast), so I wanted to get a professional opinion first. Thanks,



Terrence

I don't think you are on the right track, skunky aroma and flavor is due to light, some wavelenght of sunlight and neon light passing thrue the beer split hops oil molecule in half and one part remaning is verry close to the smelly oil that skunk produce. If it's realy the problem, try ro keep your beer in the dark during the whole process and use dark bottle instead of clear or green. Last sring i was at a terrace sipping a bitter and after less than 10 minute in the sun you could already smell de difference between a fresh served one.

If sunlight is not the problem, i would sugest making a starter, aerate your wort pitch yeast and leave it alone. Adding alcohol may be harmfull to yeast at this stage when it need to multiply, not fighting something that tries to kill it (alcohol is an antiseptic so it will attack anything living, including your yeast).

PS: Merry Xmass to all!

It won't hurt the yeast, but it won't help your beer, either. If the "skunkiness" isn't due to exposure to light, describe your cleaning and sanitizing procedures so we can see if we can help.

revieweed the comments to date Sunlight is your problem beer bottles are brown for a reason. it annoys me to go into the beer stores and see good wines basking in the sunshine. HELP, I SEE DEAD THINGS

wood grain alcohol is Not fit for huiman consumption though. besides causing death it can also cause blindness.

people have actually tried it. i only keep rubbing alcohol for cuts and scrapes. do not put it into beer or food
