Brewlabs yeast slant question?

[Martin G]

Did you factor in the reduced boil off? If you went from 90 to 60 mins it should be one third less.

[molehill]

When you say one third less.... Is that the percentage loss due to evaporation during the boil i.e reduce the percentage from 15% down to 10%? I refer to the sparge calculator.

[Martin G]

Yep, not familiar with the sparge calculator, but yes, I meant accounting for the reduction in evaporation as you state, due to the fact that the loss is proportional to boil time if heating is constant.
