HELP!!!!!!!!!!! ITS ATTACK OF GREEN APPLES IN MY AMBER ALE.
Ok so two weeks ago I kegged 5 gallons of an amber ale. I have been monitoring it and it tastes like green apples. Its only semi carbonated but smells and tastes like open a@@. Help.
from the BJCP study guide:
Acetaldehyde
This compound has the taste and aroma of fresh-cut green apples, and has also been compared to grass, green leaves and latex paint. It is normally reduced to ethanol by yeast during the secondary fermentation, but oxidation of the finished beer may reverse this process, converting ethanol to acetaldehyde. Elevated levels are generally present in green beer or if the beer is prematurely removed from the yeast. It can also be a product of bacterial spoilage by Zymomonas or Acetobacter. Background levels of acetaldehyde can be tasted in Budweiser due to the use of beechwood chips to drop the yeast before it can be reduced to ethanol.
So I am guessing you racked a bit too soon, not allowing the yeast to clean up. Typically I have found this in many beers that are made around this time of the year in competitions due to lack of temperature control, which will also contribute to this.
Hopefully it is a "green" beer thing (pardon the pun) and will subside some for you with age.
Awesome. Thanks
