I was thinking of making a geuze type lambic.
This would consist of making a batch every year for three years, then blending them.

I just don't want to have 15gals of brew.

I have 1 gallon jugs (lots of them)
I was thinking 2gallon batches for 3 years and I would end up with 6 gallons total.

I also would like to save some $$ and not buy the cultures every year.
Can I keep reculturing?
When I brew batch 2 rack onto the scum left from batch one?

any thoughts?
