A thump keg is used in distillation to perform a secondary distillation, increasing the alcohol content and improving the flavor of the spirit. It utilizes heat from the main still to re-distill the liquid, making the process more efficient and effective for producing high-proof alcohol.
I don’t nor ever have distilled. I was studying to make craft beer, though.
I brew my own as well.
