I am a new all grain brewer. I recently brewed a 5 gallon batch using a clone recipe for Courage Director's bitter. Four days later I racked it to a secondary fermenter and put a five gallon batch of oatmeal stout on the yeast bed from the first batch. I am fermenting in plastic pails. I started with seven gallons of wort in the second batch thinking I would do a 90 minute boil and reduce it down to about 5.5 gallons. I then remembered a previous appointment and had to leave so I cut the boil to 60 minutes which meant a full six gallons went into the bucket with the yeast bed. The next morning I went downstairs to check on progress and found the lid of the bucket tilted up and some beer and kreuzen on the floor. I put the lid back on and some more vodka in the air trap and it was literally blowing bubbles constantly and is still blowing some kreuzen through. My question are: Should I always expect that kind of super activity when getting two batches out of one yeast packet? Do I need to be concerned about contamination in the batch of oatmeal stout? Does anyone have any general advice about putting successive batches of beer on the same yeast bed?
I decided to jump directly into all grain brewing as a new brewer and am having a blast. (No pun intended) The two batches referred to above are numbers three and four. Also, the first two using BS and I really like the software. I look forward to hearing what anyone has to say.
