I took a brown ale recipe I thoroughly enjoy from time to time, and I took out the dark grains, and added a half ounce kent goldings dry hop for a nice summer ale.
Fermented with wlp005 at 67F in a temp controlled fridge.
Things that happened during my brewday that I am thinking could have caused this off flavor...
I like to decant my starters after I mash during brewday, and add a pint of sterile wort to get the yeast active again for pitching. After I add the pint of sterile wort, I put it in a temp controlled fridge at my pitching temp.
Problem this brewday was that I forgot to plug in the fridge, so by the time I was going to pitch, my starter was rocking @ 74-75F. So I had to chill down to my wort temp, which was around 60F and pitch, this took about 20 minutes. By morning it had a nice krausen that fell and cleared in 3-4 days.
This was also the first time I added lactic acid to my sparge water to lower the pH. I added 1/3 of a tsp to 6 gallons.
As of now I don't think it was the lactic acid, and am leaning more towards my starter temp, but I just don't know. Would that cooling down, cause enough stress on the yeast?
The beer is young for most beers...day 9 from fermentation, but I've successfully made the darker version of this, from grains to glass in 10 days before.
As of now, the beer is sitting in a keg, in my fridge at 70F conditioning more.
Any ideas of what went wrong here?
