Thanks guise!
There should be little to no lag time since I'm planning on brewing today and the other beer is ready to rack whenever. There is currently an amber ale in the carboy and I was planning on doing something simple today like a SMASH pale ale, so I figure the small amount of amber...
What if one were to, say, rack a beer from the primary fermenter and add new wort directly onto the yeast cake left over from said racking? Would this yeast cake still be viable and would there be an enhanced risk of contamination with this method?
