I love the brulosophy temp experiments, but this one needs repeating. Marshall raised the temperature of the cold-fermented batch to same temp as the other batch when gravity had fallen from 1053 to 1032. Apparent attenuation 40%, actual attenuation 32%. The "cold-fermented" lager was actually mostly fermented warm, so of course it tasted just the same as the other. In the previous two lager temperature experiments the temp was also ramped up prematurely.
