I'm using Wyeast 1968 for the first time, in a 1.048 English Summer Ale (Randy Mosher's recipe). I pitched at 66F as planned, and seven hours later, the temp had risen to 68F and the beer was clearly fermenting. After this, I let the temp get away from me, and by the end of day 1 the temp had reached 72F before I cooled it down a bit. (It hovered at 68-70 overnight.)
At 72F, in the first day of primary fermentation, did I produce fruity esters, fusel alcohols, or both? I confess that the metabolic processes of yeast confuse me sometimes--I thought that esters were produced only during the adaptive and growth phase (when my beer was at 66-68), but I realize I could be wrong.
For those with experience with Wyeast 1968/ WLP002: given the fermentation regimen I described above, how crazy do you expect my ale to taste? I'll definitely try again with 1968 and monitor temps more carefully, but what flavors would you expect to result from a 72F ferment?
Thanks in advance for your input.
