This month let's expand on the distillation process and move from the still to the doubler. Sometimes called a "thumper", this device further refines the distillate and increases the proof of the whiskey before barreling. Discussion should include: How does one operate, the differences between a "thumper" and a "doubler", typical entry and exit proof, and other general comments by those familiar with the process.
Let's further refine our knowledge of the distillation process! (pun intended)
