Less than four years old (from major producers)

[Brisko]

look at the neck band. That's where the 36 month statement is, not on the main label.

I don't know if this counts since you mentioned HH Ultra Deluxe, but Heaven Hill as such (no qualifier, the gold-and-black label and 40% ABV) also is 36 months now. I seem to recall it being NAS in the past, but maybe I never looked carefully enough because I almost never buy it, the HH Bonded is indeed the way to go (IMO) for its lower end.

Don't worry Brisko, I was just in a store earlier that day and found the AA age statement myself.

Yellowstone is also 3 years old according to my 90 proof bottle. Then there's the Hirsch/McCormic corn whiskies that are aged for only a few months.....
