confused by pitching rates on Mr. Malty
« on: October 12, 2012, 06:40:46 pm »
So I was entering my infor mation on Mr. Malty's yeast pitching calculator and noticed something that I found odd.  This is only my fifth yeast starter so maybe this should be obvious but here it goes. 

I'm doing a simple starter of WY1056 with intermittent shaking for a 5.25 gallon batch. When I entered the OG as 1.056 the calculator indicated I needed a 1.85 L starter.  When I entered an OG of 1.063 it recommended a starter of 1 L.  When I entered 1.07 it recommends a 1.21 L starter.  I thought a higher OG wort would need a larger starter.  Is there a zone of optimal development?  Is there a point of dininishing return?

When you entered the higher OG, did it bump up from one pack of yeast to two?

Ohhhhh, I feel stupid.  It bumped the number of vials/packs up to two.  Dohhh!  I'm blaming it on the glasses of Tank 7.

That's a damn good reason.

I was interpreting it as a 1L starter or 2 packs/vials of yeast- not a 1L starter made with 2 packs/vials of yeast.
