Blow off question
« on: August 27, 2016, 04:28:20 PM »
A week ago I brewed an ale-toberfest.  The OG was 1.062.  I pitched a 1 liter starter with 2 packets of wyeast 1007 in it.  I put it in my chest freezer and set the temp to 58.  I set it up with a blow off into a 1 gallon carboy half full of sanitized solution.

Upon my return from a week long work trip today, I see that the fermentation overflowed the 1 gallon carboy and made a nice mess.  In the 1 gallon carboy there was roughly 3/4 inch of a yeast bed.  In the freezer there was quite a bit of yeast as I was wiping up.  I took a gravity reading as well and I'm sitting at 1.030.

I am not too worried about t he gravity right now as it's a little early to tell but my question is this...do I need to add more yeast to account for all the lost yeast in the blow off carboy and bottom of the freezer?

I'd say absolutely not.  You already way overpitched.  There should still be plenty of yeast left in the beer.

While I haven't had the overflow, I have always wondered about the blown yeast. I figure the remaining yeast would bud to makeup for the loss.

What do you consider an over pitch?  Beer smith estimated I needed 227 billion cells and my starter would have been roughly 265.  I figured that would be okay especially fermenting on the lower side of the temp scale for my strain.

I have stopped using yeast calculators.  In real life it doesn't make that much difference.  I've found by experience that a 1 qt., 24 hour, SNS starter is sufficient for my beers up to a mid 70s gravity.  That's all I need to know.

Fair enough...maybe I should start doing this.  I feel like I stress too much about pitching rate.  I know this is a real silly question but what do you mean by an SNS starter?

I would assume that someone, like me, who usually brews three gallon batches could go up to 1.100, or higher with a 1 qt., 24 hour, SNS starter.

Also, not really sure how much yeast you are actually growing with 2 packets in only a 1 liter starter. I would bet that those yeast would just be getting going with that amount of medium to consume. Typically, I would not go any smaller than a 1:1 ratio of yeast packet to starter size (quart/liter).
