Ed, since you are on here right now do you have any insights for me, it was fantastic for 2 weeks and now pretty skunky. Is that just the way wheats are?
That is NOT the way wheats are. If it's skunky, that could indicate that it got light struck. Did you have the fermenter or bottles out in the sunlight?
Generally wheat beers have a short life, but they are not usually skunky, and by short life I'm talking tasting stale. 3 weeks is not too young, and definitely not too old!
Pay attention to how much sun or flourescent light the beer gets during and after fermentation. Also watch for oxidation after fermentation, especially during bottling.
