Title: beer contamintaion
Post by: eaholljr on November 06, 2009, 06:31:48 PM
Hello all!

I have a question about beer contaimintation:

How can you tell visually when your beer is contaminated. I'd like to know from primary, secondary, bottles, and kegs. If anyone has pictures of this, that would be a GREAT visual! Thx!

This one was done intentionally (see my mango beer recipe)

A big clue is that the beer is cloudy, but it's not chill haze or yeast.

The reason I am asking this is because I have NEVER had this happen to me yet.  Does mold look like mold (bread mold)? I just need some close ups pix or illustrations to give me an idea. I'd hate to work so hard at something and loose it all to contamination.

Thx

This is a good sign of an infection.  It was a stored yeast sample that accidentally got left out of the fridge.  The same thing hit my pear cider when, due to a set of unfortunate circumstances, I had to neglect for a month.  It is probably acetobacter from fruit flies.

But, just because your beer may look ok, doesn't mean it isn't contaminated.
