The fault I am noticing smells and tastes strongly of hose water on a summer day when you first turn it on. I don't use hose water and I've had the majority of my batches come out smelling/tasting fine. Some information that might help diagnose what I am dealing with below.
1) My teacher in a home brew class brought in a beer with a fault that he called DMS. It smelled/tasted like what I am experiencing only not as pronounced.
2) I temperature ferment around 65 in a refrigerator that is holding its temperature steady.
3) I've brewed ~12-15 batches this year and 2 of them have had this fault to an extent where it is undrinkable, the other ones were fine.
4) I've given the first faulty batch (wheat pils)over 6 months to try and clear up to no avail. The second batch (oktoberfest fermented at 50F) is a couple months old and is still faulty as well.
5) I harvested American Ale II yeast from a pale ale that came out as my best batch of the year. I went to pitch it into a brown recently and upon smelling the first bottle it contained said fault. When I opened up a second bottle it smelled fine, worked fine. These bottles were harvested from the same batch and stored in the same conditions for the same amount of time.
6) Wort going into the carboy smells/tastes fine, beer coming out does not. I use diluted bleach to sanitize carboys and make sure to rinse thoroughly. This is the only thing I can think of that might be causing it other than under-sanitizing.
Thanks for your help!
