I am currently using an 8 gallon Enameled kettle to do the BIAB method using 16 pounds of grain. I start with 6 gallons of water and fly sparge another 2 gallons over the top. I end up boiling 7.5 gallons and have 5.5 gallons of wort post-boil. I'm getting between 70-75% efficiency and around 6.5% alcohol content.
I'd like to get a higher alcohol content, so I'm in the market for a larger kettle. I'm not sure if I should get the 10 or 15 gallon. I know that a 15 gallon kettle will be all that I will ever need because I enjoy 5 gallon batches and love having variety.
But I am thinking that the fly sparge and/or a mash out is necessary in order to get better efficiency using the BIAB method. In that case I don't think that I'll need anything bigger than a 10 gallon kettle for my 5-6 gallon batches.
What do you think?
