What is the proof of this Yellowstone bourbon now?
Back in the mid-70s, my parents bought a bottle of Yellowstone Kentucky Straight Bourbon. It was used mainly for fruitcakes and spiking egg nog at Christmas. Both my parents are deceased and I have the job of empyting their house and selling it. Cleaning out the fridge, I found this half bottle 4/5 quart of Yellowstone Bourbon, still in its box. Question: if the proof was 90 back in the 70s, what would its proof be today, after 32 years and would it be safe to make a “drink” from it?
