As The Trub Turns

Came home to the Saison fermenting like crazy mad (technical term). What was most surprising was that the trub, which had been at least 5 inches thick, is now basically all swirling through the beer. It's a violent fermentation. There is also about 3/4th of an inch on the top. All signs point towards a strong fermentation for this beer. So much for a delayed start!
