I thought this was the right place for a discussion about the heritage of the Beam brand.

I note from the Jim Beam website that the first Beam, Jacob, is mentioned as a distiller and founder of the brand (presumably the recipe for what is called today Jim Beam bourbon). He lived in the late 1700's. The timeline states that he made "Old Jake's Sour Mash". That is a specific statement and I would assume just on face value it is true. Is this in fact not so, i.e., is there no evidence that he distilled or named his whiskey in this way? I honestly don't know and am just asking. I would like to read Still Life but haven't found a copy yet conveniently.
