Ever hear of a Lagered Ale, Kolsch? Think thats supposed to be about 55 deg
Actually, no. I thought that Lager yeast thrived below 41 degrees during the final fermentation process...which are filtered out and the beer returned to warmer temps to stop any further fermentation. Thus the warm German beers.
Conversely, top fermenting ales utilize brewer's yeast that likes warm temps so after final filtration to remove the yeast beasties, the brew is kept cold to retard further further fermentation.
A Lagered Ale....sounds like an oxymoron.
But then...I don't brew 'em...I just drink 'em.
