My g/f & I have a dozen or so single malt Scotches here. The favorite is a Balvenie 21yo Portwood, a close second is a Glen Rothes 29yo. We tend to like the Highlands the most. There is a bottle of Glenfiddich, but that was given to Deb as a gift.
We do have a couple of Irish whiskeys, John Powers (mostly for cooking, but does nicely on it's own,) and a couple of older Bushmills. And a bottle of Maker's Mark bourbon.
I found a tequila I can drink straight. Herradura Seleccion Suprema. It's an anejo, and while I can find it in this country, it's up around $270/bottle.
