I find the ales I brew, which are generally lighter of the style, tends to come into its best after week 2 to 3. Yes they are carbed up, but they still seem to meld together better after that time, in the keg, I don't drink from the fermenter....very often, sometimes the supplies get low and I try the old timey method of dunking my tankard into the fermenter...I read it in a D&D book once.
My experience with lagers is that they turn out better when they aren't quickly dropped down in temperature for the lagering phase, rather ramped down over a few days. The main advantage of a freezer is better insulation, which would be pretty useful up in FNQ. Other than that, it probably uses a bit less power when bringing the temp down the fractions of a degree during fermentation but I doubt it'd be noticed on a power bill.
Yeah it was on tap there John, & I nearly had one as it was a damn cold day there that day. But I wanted to get around the place & try beers from as many of the breweries as I could for information gathering purposes, but didn't want to end up a crab-walking drunk by the end of it, so behaved myself to a fair degree. Off the back of your very own recommendation of the Crankshaft IPA, I made sure it was one of the beers I tried on the day. Damn glad I did. Unfortunately they lack a distribution network here in SA for their beers, so they are very scarce to non-existent, that is a real shame.
