Extract brewer here - I attempted an IPA that was supposed to have an OG of 1.070 and FG of 1.016 using white labs WLP001 yeast and pilsen DME. I made a starter for this, my first time doing so, and don't have a magnetic stirrer so I used the 'shake whenever you're around method' for about 32 hours before pitching.
Anyway, the OG came out near-perfect at 1.069, but the FG was at 1.005 (0.011 too low) after 15 days of fermenting. I then cold-crashed (3 days around 33 F) and kegged the beer. The resulting beer tastes pretty bad, solvent-like (paint thinner?) and harsh on the back of the throat.
So I read about solvent-like flavors and it's supposed to be from fermenting at too high temperatures. However, I use a temperature-controlled cooler, and my recorded temp range for the 15 days was max 72.0 F and min 66.6 F, which is pretty close to the recc'd range for wlp001 (68-73 F optimum). To control the temp, I tape the temp-controller probe to the side of the fermenting bucket near the middle.
Could the internal temp in the bucket be significantly higher? Or could I be dealing with an infection instead? This isn't something I've seen before (about 5 good batches brewed in the past). Thanks for any help!
