IMO, Pikesville is the gold standard and I have that. You can't beat it for the price. I just opened a bottle of Fiddler Toasted Rye which is good. I'm not a huge fan of JD Single Barrel Rye. Whistle Pig is very mediocre for the price.
Any suggestions in the sub $100 category that isn't allocated?
If it's distributed near you, Riverset Rye single barrel cask strength (not the basic 94 proof version) is great and very high value for the price (~$45ish).
Wild turkey rare breed rye and Russell's single barrel rye are both good. Rare Breed is higher proof and more intense, Russell's is an easier sipper (104 proof). My last Russell's reminded me of Apple Jacks.
I'll add another vote for Whistlepig 10 yr. My dad found a bottle for $65 which is fantastic value. It's $90 here in Alabama, which is pushing it. It's friggin delicious though. Great sweet oak and baking spice balance.
I've also heard Wilderness Trail Rye is really good (especially the store picks), but I've never had it.
