Intermediate brewer that is very frustrated with yeasty off flavors after kegging and carbonating.
For the past three extract batches, I have ended up with strong yeast aroma and flavor alongside a water downed taste of the beer. I am a sanitation freak, and have never had this problem before. I started using a freezer with a temp controller for fermentation, so I am able to lock fermentation temps in better than I ever have before as well. The wort of each tasted/smelled great, the OG and FG were all spot on according to the instructions, and fermentation was without any hitch as well. I am careful to clean and sanitize my kegs and equipment, which I know this would likely be something in the keg or line creating the off flavor due to contamination. I just don’t know how.
I just can’t seem to shake the flavor off, and I plan on doing my first all-grain batch on Saturday and don’t want to end up wasting all that time and energy to end up with crappy yeast flowered beer in the end.
Any thoughts, suggestions, or solutions?
