Bourbon Family Tree from GQ Compared to something like the number of Scotch producers, there are relatively few producers of bourbon - most are related by production lines and distilleries. GQ published a nice info-graphic which has been excerpted from The Kings County Distillery’s Guide to Urban Moonshining. It doesn’t have some of the other brands, like Hudson, but it does a great job of showing how most of the different brands and makes of bourbon and rye are related.
