There's no other category! First one or two pours of a new-to-me whisky go into a Glencairn glass, a souvenir from the Edinburgh Tattoo. As this is supposed to be the ultimate 'tasting' glass, I use it first. Next I might use a Reidel single malt glass, but not always. I use both of these as a tasting/sniffing/examining...glasses.
After that, once I have a feel for the whisky and just want to enjoy it (so, really, the vast majority - 600 + mls - of each bottle) I use a glass that Bruichladdich was giving away a few years ago in the 15yo cans. Sort of a tulip shaped tumbler that fits perfectly into my hand.
