I gotta tell ya, just between us girls, that Revvy is HOT. Very tall, gorgeous grey hair and a terrific smile. He's very good looking in person, with a charismatic personality... he drives like a ****ing maniac! - YooperBrew
I would like to know where this myth about not getting krausen when making cider came from. I have made literally hudreds of batchs of cider and somtimes you get krausen and sometimes you dont... its facts of life, based on many many variables, so dont think you sound not get krausen and you should be fine.
Also you might need a blow off tube, rig one just to be safe.
