Mash Volume Issue
« on: June 30, 2020, 03:07:09 PM »
I am using a 32 litre stainless steel brewpot (34cm wide, by 34cm tall) and a grain basket that is 30x24cm and holds about 8 kilos of grain.  I usually use around 4 kilos of grain, which takes up half of the basket and about two thirds of the pot height.  I mash and sparge in the pot. 
I followed the video on here as best I could to create my own equipment profile.
Beersmith tells me to mash with 9.65 litres, and sparge with 25.89, but 9.65 wouldn't cover the grains.  I mashed with 18.2 litres yesterday and it was right on the liner of the grains.  I sparged with 13.6 litres (so 7 gallons all in) and ended up with 19 litres when I was done.
Can anyone help with why BS says to use less water than it takes to reach the top of my grains?  Its saying use half as much as I actually need.

I can take a guess that you did not account for the deadspace under and around the basket, or you can post the recipe you are using as your example as a .bsmx file and we can give you better advice.
Recycle your grains, feed them to a goat!
