Just kegged my Dunkelweizen, I let it sit in primary fermenter an extra 2 weeks (5 weeks total) due to some excess sulfur. The sulfur flavor is gone, but it kinda taste like tea, with a slight lemon flavor. I have not seen then in any off flavor guides. any ideas?
It’s quite likely an issue. PH strips tend to read a bit low, although pH of the water doesn’t tell you too much. What kind of filter? Do you have a water report? Water calculators are pretty accurate, so if you have a starting water profile, it makes the pH meter unnecessary.
Might make tannin extraction less likely. However, other flavors can mask it during earlier stages of fermentation. How have your previous batches turned out with the same water source?
However I think I might now what it is. Looks like it was infected. Still the flavor is pretty odd for an infection. This is my fermenter when I went to clean it out.
Also at one point the temp dropped in house creating a vacuum on the air lock. Some starsan got in there, so possibly some oxygen too. looks like it might be acetobacter infection…
Yeah, it looks like you had a pellicle on it when you transferred or bottled. Probably LAB, hence the lemon flavor. There’s an infected batch thread in recent topics, might be helpful in recovering. Drink it fast, and up your sanitation game for the next couple batches. Most of the equipment will be ok with a good cleaning.
So I just had a bottle of new glarus moon man (APA) from a trip last spring. And it tasted like… black tea with a slight lemon taste. Going to second loopie’s suggestion of oxidation. This beer is definitely oxidized, and having a sample in my glass, I get that flavor.
Why oh why would you treat my favorite beer like like!?!?!
All joking aside I can say I never had Moon Man sitting for almost a year. Have a trip planned in August as I will try to get tix to The Great Taste of the Midwest. May only bring back as much Moon Man as I can.
