I have a 3 gal. brew kettle and want to try "Texas two-step" brewing to avoid the caramel flavor I get from partial boils.
1) If I do two boils over two days, should I add all or part of my starter to the first half-batch?
2) Can you simply take a 5 gallon recipe and cut all the ingredients in half to make each half-batch? I also have several lab-grade 9.9 liter Pyrex carboys I want to use for small batches and I'm trying to figure how to adapt 5 gal. recipes.
I'm saving for a 8 gal. brew kettle and propane burner but in the meantime, any tips for doing this two step method would be greatly appreciated.
