I have a five gallon batch of cider going that used wyeast champagne liquid. it has been fermenting for two weeks now in primary and still bubbles every nine seconds. is there any length of time that it needs to remain in the primary? or should i rack to secondary now to get it off of the spent yeast cake which is pretty big. I started this batch with five pounds of fermentable sugars. I'm imagining it will finish very dry. Thanks for any info.
