Picture of Mashbills, Geeky Information and Resources

This is the last installment in a series on Bourbon by Zach Pearson. Read them all: Bourbon, Bourbon After the Act, Bourbon: What it is ... and isn't, Making Bourbon, Who Makes My Bourbon, Producer Capsules., Finding the Good Stuff, Tasting the Good Stuff, Neat, Mashbills, Geeky Information and Resources.

As a note, I can’t claim credit for any of this. This section is the work of a couple of users on the StraightBourbon.com website, mainly Josh, Oscar and a guy named Taanstafl2 – and see the note just below. But it’s too important to leave out even if it’s a bit more advanced.

For mashbills, I referred to The Book of Bourbon and Other Fine American Whiskeys by Regan & Regan, 2009, unless otherwise noted. Barton, WT, and Dickel are noted as approximate.

I use the format: Distillery Brand Name (%corn/%rye or wheat/%malted barley). This is a breakdown of "macro" distillers. Wondering what the different char levels look like? This is a good illustration.
