I went to the store to look for something inexpensive enough that I wouldn't feel bad using it for baking (bourbon pecan pie) and soaking cocoa nibs for a homebrew, but also nice enough that I could still drink it. A couple things caught my eye and what I ended up grabbing was Old Grand-Dad 100 proof bottled in bond. I'm pretty sure it's been talked about on here which is probably why I recognized it.
It's really good. Super smooth, heavy vanilla aroma, light cinnamon spice from the rye. Easy to drink neat, even smoother with a small chip of ice. Not much heat or burn for being 50%. I'd argue it's much better than Jim Beam even though OGD is "made by Jim Beam".
It's $24/750ml here in Oregon, so not dirt cheap but also not top shelf. It's in the same price range as Buffalo Trace, Bulleit Rye, Evan Williams Green Label, Makers Mark, Old Forester 100 proof and a few others. I'd say it's likely better than most of those, except the Bulleit Rye which is one of my all time favorites. It's funny now to scan the price list and see Bulliet the same price as Evan Williams. I wouldn't pay half that for EW.
Based on store placement, you'd think it wasn't very popular. It was on the shelf one up from the bottom, and right on the edge between whiskey and rum. It was almost "hidden". Although, when I had it in my hand one of the people working at the store asked if I needed help and then said "That's a good choice right there". They were right.
