Let's see... a lot of this is going to sound a little weird. But here goes.
For coffee, I've stayed with Gevalia's Stockholm Roast for ages. Favorite tea would be Earl Grey or the Queen Mary tea by Twinings (which I've never found available in the States), along with lots of the herbals... Red Zinger, Almond Sunset, and several others. Caffeinated soda favorites are Mtn. Dew and Dr. Pepper. I also use sodas mostly not as they are but just to add a hint of flavor to water. I don't really like drinking plain water, so I'll fill a glass about a 1/4 way with Sprite, then add water to the top. Rarely use ice or even bother to refrigerate my sodas/etc.
No real preference between American beers and I don't remember the names of those I liked best while I lived in Germany (early-mid 80s). For wines, I'll usually have a Piesporter or Riesling/Spatlese. Columbia Crest (Washington) puts out a Gewurztraminer that I really like. I've always intended to order that by the case, but never have. Also like a few of the sparkling wines or sekt.
As something of a family tradition, we celebrate special or fun days (birthdays, anniversaries, or events like the Super Bowl or Indy 500) by having a champagne breakfast.... which would be at least some cold ham and hot cinnamon rolls as a starting point, usually with either champagne cocktails or mimosa.
When having margaritas, I'd rather not have mine blended into a slush with crushed ice. If I'm out, I'll usually order something like scotch and water or maybe a gin and tonic. At home, I usually have some gin, Canadian whiskey, vodka, and tequila on hand. Favorite liquiors are Amaretto, Bailey's, Kirsch.
