I have an unusual aroma in a helles that I recently made I would describe it as Play-Doh or possibly wet flour (like bread dough before the yeast begin to rise. I have never come across this smell before and I have made this recipe 3 other times. In this case there were some strange things that happened on brew day because I was fiddling with my process a bit but fermentation went as expected.
Details:
10 gallon batch
95% Pilsner, 5% Munich, 19.5 IBU's from pearle at 60 min , .5oz hallertau at 15min
Shooting for 1.048 OG but ended up with 1.054 (efficiency of 82% due to process changes was higher then expected)
Yeast - repitch of wlp 830 from a 6% oktoberfest, pitched at 46 raised temp 1 degree per day to 50 and fermented for a total of 4 weeks.
final gravity is 1.008 (6.03%ABV) - in previous batches with old process FG was 1.011 for 4.85% ABV. Fermented in Morebeer cooled conical.
The slightest bit (maybe a few ounces) of star san might have been sucked through the blowoff into the beer (10 gallon batch)
Anythoughts on the play-doh / wet flour aroma? Thanks guys.
