I use Glencairn glasses for all my spirits. The tulip shape performs the same function as the snifter, concentrating the aromas to enhance the flavor experience. I wash them by hand and then rinse with water from the R/O spigot. That might be a little over the top, but they never have residual smells that way. My favorite beer glasses look like larger versions of the Glencairn glasses. They are sort of like snifters except tulip shaped. One has the Duvel name on it and the other has Hoegaarden. Both are nicely aromatic Belgian beers.
