Hi - I'm trying to piece together a technique to do an all grain brew with limited equipment.
My plan is based on the Maxi-BIAB concept, but I'm aiming for the highest possible pre-boil volume so I don't have to worry about boil additions. Can anyone see any major flaws in the following.....
Mash 4.8kg of grain (in a bag) in my 20l brew pot in 12 litres of water (2.5l per kg)
Near the end of the mash, heat another 12l of water to sparge temperature (I'll take the brew pot of the burner while mashing to free it up to heat the sparge water).
Add this 12l of sparge water to a bucket (I'm thinking a spare plastic fermentation bucket).
When mash is over, pull the bag, let it drip before dropping into sparge water in fermentation bucket, stir, squeeze, dunk etc.
Meanwhile start heating liquid left in brew pot.
When done sparging, tip water out of fermentation bucket into brew pot and commence boil.
By my calculations....
from the initial 12l litres of mash water, Ill be left with approx 7.2 litres in the brew/mash pot (12l less absorption of grains own weight (4.8l))
addition of 12l from sparge bucket
total initial boil volume of 19.2l
Post boil, I'll top fermenter up to desired volume (21 litres) diluting to desired gravity.
