I'm the same way....sampling the many bourbons that are still out there is challenging enough for me without adding the glassware variable into the equation. I'd like to purchase the Riedel glassware and the Blender's nosing glass at some future time but right now it's not a major concern.
I do have a couple of brandy snifters that I've occasionally used to sip bourbon but, like Greg, I find that the nose with these glasses is usually overpowering. I hope that when and if I purchase other nosing glasses like the Riedel that these glasses will provide better nosing than the snifters.
I almost always prefer to use my Jack Daniels lowball glass. I guess some here would consider that blasphemous, but I don't really care what's inscribed on the glass; just so long as it doesn't say something stupid like 'War Eagle' or 'AU'. (Had to throw that in since college football is right around the corner!).
Anyway, the JD lowball has thick glass sides and is nicely weighted. I really enjoy it. Strangely, I did not get it at any of the shops in Lynchburg but at some gift shop in a mall several years back. I actually haven't found any lowball glasses of similar quality in Lynchburg.
