I think I need several pints of Coopers if I am to even begin to understand all that - and I need to start on it right now. What a great excuse.6470zzy wrote:"Isoamyl alcohol and acetic acid can combine to form isoamyl acetate, which can give beer a banana-like flavor. Since a given yeast strain can uniquely determine which acids and alcohols are produced during fermentation (and in what quantities), it makes sense that ester production is also a characteristic of a given yeast.
Ester production increases with higher fermentation temperature, lower levels of dissolved oxygen, higher gravity wort, and lower pitching rates. If you’ve noticed fruity, solvent-like, or banana flavors in your beer, try brewing a few mid-gravity beers with original gravities around 1.050 or below, aerating well (better than you have been), and using an adequate pitching rate."
That info is what I just lifted from an article in BYO magazine and I believe that it adds to the discussion, what do you think?
Cheers
Thanks and Cheers:)
