I used to purchase this regularly, back in the day (early 70's). If I recall correctly, I think it was 90-proof back then. In those days, it seemed to me to be a great value - pretty good whiskey at a reasonable price. I moved away from it, literally, moving to a state where it was no longer available to me. So, I haven't had any in at least 30 years.
Now it is Heaven Hill whiskey and I feel like it should be a cut above their standard bottlings, but I don't know that for a fact. I would use it as an everyday pour and for mixing duty. My best advice is, try it and see.
PS - Maybe, after reading all of the above, it is not produced by Heaven Hill, only marketed by them. I really don't know.
