Last weekend I made a partial mash that included 1.5 lbs of malted rye. Its been in my primary for 5 days now, and i still have a thick krausen. Is this normal for a beer with rye involved? I've read before that for some rye all grain brews that a stuck sparge coud be a problem. Does this have any connection to my krausen "sticking" around longer than normal? Should I wait until it goes down to rack to the secondary?
