I am making my second beer (first lager). It is a Brewers Best dortmunder gold lager kit.
I made the wort and put it in a primary for 3 weeks at a fairly constant 54 degrees. I have moved it to a carboy, and been lowering the temperature on it daily for one week.
My problem is that I've kept it on the patio in a box to help maintain the temperature, but the temperature has gotten sunny here for the last couple days and I think my beer has probably gotten up to the mid to upper 40's, then back down to the lower 40's over night.
I asked my local brew store about this, and they pretty much claimed bloody murder saying that the beer is probably ruined, and I must bottle it to save it if it isn't already ruined. I read that people just let it lager for a long time though... so I'm confused.
