I have a 70 litre pot and I've been doing 23L batches,however I really like my last Abbots ale
and I'm thinking of doing a double batch. My pot will only let me go to a 40l batch so I'm looking
at Maxi Biab and sparging with the extra 6 litres to get a better efficiency.
I thought it was a case of just doubling up on all ingredients but I've been told I should add an extra 10%
on all grain & hops to make up for the efficiency and lost hop utilisation.
How do others do it?
