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?
Too high of a pressure?

One of my best lagers reached about 33psi on accident. It'll be fine
Did that as soon as I caught it. Thanks.
The pressure isn't too terrible for the yeast. You can go pretty high rates before any significant issues happen. A lot of breweries maintain ~28psi pressure on their lagers. I have tried that before in the past with a few lagers as well with great success. Of course I had to plan and severely overpitch the yeast but it worked like a charm. Worst thing you likely did was mute a lot of the flavors on the yeast which is likely what you wanted anyways with the 34/70. Let us know how it turned out! But it should be just fine.
Forgot to update the thread, thanks for the reminder. I don't know that my palate's all that refined, but the beer seems pretty good to me. It's been in the keg about 1.5 weeks, and tastes pretty much like what I was trying to clone, with no ill effects that I can notice.
