Jack Daniels is NOT a bourbon whiskey....It is a sour mash whiskey...
Quite right, my bad. Another reason that I don’t drink it.
Pretty much all bourbon is actually sour mash. All that refers to is the use of some previously fermented mash from a previous batch (with active yeast) in each new batch, sort of like sourdough bread starter. Most bourbon distillers mention this process somewhere on their websites.
Some Tennessee Whiskeys use the "sour mash" designation on their labels simply because they can't legally use the word "Bourbon".
Thank you. Living about 50 miles north of the facility in Lynchburg we know the difference.
