doubler

[papa]

Just started last summer with a fairly large (homemade)copper still,just doing single runs.This next season I plan on using a doubler between the still and the worm using mash made as same as the main run in the still.My question is; should I heat the mash in the doubler,( I have the capability ), or leave it at ambient temperture?

The mash will heat when you start running.

the thumper does its magic by creating a thermal difference between the two stages. it is this difference that encouraged water to drop out of the vapor, and alcohol to continue.

heating your thumper might not hurt for initial warm up, but I would shut the heat down once you're up to temp.
