I know that primary ale fermentation increases wort temps by 5 degrees or so, does this apply to lagers as well? Reason I ask is that I can't get my fridge up to sustain 50-55 degrees, my basement is too warm at 65 and my basement bulkhead is too cold at 46-48. I'm thinking that the bulkhead may be OK if the wort runs 5 degrees warmer, albeit on the low side of the fermentation temp range (WLP820 @ 52-58). Any thoughts? Should I throw it in a water bath with frozen water bottles instead?
