Kegged some truly awesome beer yesterday, an Amber German Lager. It was so good, we were sampling it right out of the fermenter.
Harvested the yeast (3rd Gen, 34/70), in a large glass jug with an airlock. It is being stored in a spare kegerator, at 36-38F
But it is now fermenting like crazy, with a large thick krausen built up, and bubbling away. Is this to be expected? My other yeasts in storage (same location) are pretty much dormant.
