Old Thompson is not a bourbon, but rather a blend of whiskeys coupled with neutral grain spirits (vodka).The nose is almost nonexistent with hints of gasoline and nail polish remover, along with the slightest whiff of what might be corn sweetness. On the palate, Old Thompson is harsher than its proof would suggest and offers an unpleasant sweetness that doesn’t seem to draw from the whiskey in the product. These flavors are followed by a short finish and lingering bitterness.
