Just brewed my first lager over the weekend, which will hopefully come out as a good clone of Korbinian. It yields an OG of 1.078, calls for two packages of 34/70, and fermenting at 65°F under 15 psi for 14 days. I goofed setting my spunding valve, and by Monday morning the pressure was off the scale--I'd say 30+ psi. I turned it down at that point, and it continues to ferment away--SG has dropped from 1.055 to 1.040 according to my iSpindel since then. How badly is this likely to have messed up the beer?
