    Cold crash suck-back volume estimate?

    is there any general guidance for the volume of gas being sucked back when cold crashing? E.g. if I have a 6.5g carboy and 5.5g of beer, and I cold crash from 68F to 35F, what volume of gas should I expect to suck-back? if this is pretty constant and predictable, I'd like to create a large...

    Calculating partial boil recipes and Beersmith

    I'm sure I'm overlooking something obvious, but I just can't see it... I'm trying to calculate a few recipes for a stove-top partial boil in small pots. Instead of boiling 3kg of malt extract topped up to 15 liters, I want to boil 1kg of malt extract topped up to 5 liters, then add the...
