Umm... I hope everyone is ready to try a sour beer.
It already had a nice acidic backing to it, but I think its actually getting MORE sour as time goes on...
I tried to pasteurize it for 30 minutes about 5C below the ethanol evaporation point; a supposed "low temperature, long duration" method, but I'm thinking that SOMETHING survived the process; considering how fast the acidity has increased and considering that lacto has the highest heat tolerance I know where my money is.
By next Thursday I expect it will be more sour than roasty/bread crusty.
I still like it a LOT but I think I have more of a tolerance for sour than most.
(Looks like I'm going to be buying new keg gaskets and beer line after this one.... CRUD.)
Organisms that are both pretty temperature AND acid tolerant... what did I get myself into? -Maybe I should resort to a caustic cycle to make sure I can kill these things when its all said and done. (Caustic scares the crap out of me, though....)
Hmm... The CO2 is cranked WAY up and the temperature WAY down; CO2 is technically an acid. -John, do you notice an increased perception of acidity as CO2 levels go up, or are we talking about PH decreases below the perceptible level?
-I'm going to crank the CO2 down and taste again in 2 days.
[Edit] It WAS the insanely high CO2 + the low temps which were hiding the roasty/toasted bread notes. I like this one better with lower carbonation and higher temps. It's probably going to be a shock to the system for some people with brown malt, high acidity, brettanomyces flavours, and considerable oak flavours, so it could be 5 new flavour experiences in one beer.
