Default Oxidation

How likely is oxidation to occur when the beer is in the secondary and you break the seal on the carboy to theif out some beer to take a gravity reading? Also how quickly can beer become yeasty during sitting in the secondary? Months? Years? I know it's a process that takes time, but what I'm getting at is I know year old beer taste differently that month old beer. Obviously that takes a year, but when does the change really start to occur?

Thanks,
Mike

Oxidation is not likely...

What do you mean by becoming yeasty? Are you referring to autolysis?

No chance for oxidation getting a sample unless you decide pick up your carboy and shake the heck out of it.

I don't know what you mean by yeasty but I've left beer in secondary anywhere from a couple weeks to 18 months and they all tasted fine when they were drank.

A year old beer does taste different than a month old beer but it really depends on the beer. Some beers just get better after sitting a year and some not so good.

The flavor change/improvement of the average beer comes at about 2 to 3 months after making.

Extremely unlikely.

(Is Budweiser distributing pamphlets about how hard it is to make beer at home?!! If not, why are there so many 'scared' posts this week?)

The second part of your question is a little bit impossible to answer. Yeast is a very hardy thing. Autolysis is highly unlikely for the homebrewer. 'Change' starts to occur the moment you put yeast in, and it never stops. When that change becomes noticeable is impossible to determine in this case - it can vary with every brew.

I'll say this, good homebrewers have beer that is 4,5,6.... and so on years old. It it's stellar, award winning stuff. And some people have 6 month old beer that sucks.

That's a pretty broad statement. It might be true if you're talking about some form of lambic or Belgian style. Generally most styles won't hold up that well no matter how good the homebrewer is. Maybe I just like to drink 'em young.


I'll wait on my Flanders Red for a couple of years though...

Just curious, why a gravity reading in secondary? Fermentation should have completed before the transfer.

I should have said, good homebrewers CAN have beer that is that old. Stored cold, properly, and made with clean sanitation many but the lightest styles should be fine.

Jamil enter 6 year old beers into competition this year that weren't lambics, from what I heard.

Anyway, it's possible. So you can't throw an opposing broad statement (not that you did) that beer will begin to suffer the effects of ageing at XX point. Because that simple isn't the case - That's all I was trying to say.

I also do not understand your use of yeasty.

If you're using Jamil Z. or some of the other rock star brewers as standard examples of good homebrewers, then you eliminate many good homebrewers. That's all I was trying to say.

Yes, it is possible, but many styles, regardless of the brewer's ability, do not have a long shelf life.

peace

still missing my point man.... i didn't say beer will last 6 years. i didn't say it won't. i said it does, and it may, and it may not.

JZ or me, or you....doesn't matter. My point is that there's no answer this guys question of "when does the change start to occur" other than that "change is ALWAYS occuring".

Good beer has no predefined time limit. I think we agree on that.
