Yast Starter Calculation wrong
« on: January 13, 2019, 03:22:24 AM »
I using Metric Units.
I realized that the yeast starter Calculation seems to be wrong.

For 23,4g of Dry Yeast i should add 585 ml Waster and a CRAZY HIGH amount of GoFerm (29,3g)

GoFerm dosage is ~25g per 100 Liter so this can't be correct in any way.

Fro the scott labs web site here they mention for an arbitrary pitch rate (at the bottom) use:
  1 part yeast to 1.25 parts Go-Ferm.

I believe that is what BeerSmith is using.  If you read it carefully they are recommending 30g/hL of goferm but that is based on a yeast dosage of 25g/hL.  So those numbers are also consistent with the BeeeSmith recommendation.

23.4 g of yeast is quite a bit...enough for almost 100 L at the pitch rates Scott labs is using.
