I was finally able to score a bottle of the George Dickel Rye. It came to $18.52 including Maryland's increased 9% sales tax.
I tasted it along with Pikesville Rye. I really did not notice much difference.
I don't know if Pikesville is 95% (or a great percentage) rye, but to me, with my taste test of rye neat, it was pretty much identical to Dickel Rye, and $5 or so cheaper.
I'll have to do a comparison with Manhattans, though if neat was similar to me, I don't think cocktails will be different.
One positive the Dickel had over Pikesville is that Dickel has a cork stopper and Pikesville is a screw-off cap.
