Dam! That's a question that will take a long answer...
Red wines, I'm not prejudiced. So, in no particular order:
California zinfandels: Cardinal Zin (by Bonny Doon), St-Francis...
CA others: St-Francis cab ; Liberty school syrah; Ca Del Solo charbonno; Terre Rouge mourvèdre; Raymond cab...
French bordeaux: Haut-Médoc in general (St-Julien, St-Estèphe and Pessac-Leognan in particular), I always vary the vineyards - there are so many...
Other French: mostly Rhône syrah based wines, and small southern vineyards (like Bandol) who use mostly mourvèdre...
Italian Brunello di Montalcino: anything from Bruno Nardi; Italian chianti: I vary, but the Il Grigio is a staple...
Other italians: Valpollicella classicos, Sicilian wines (very surprising)...
Others: Chilean carmeneres (not the cheap ones); Australian syrah (not he cheap ones); tannats from Uruguay...
White wines: these days, I pine mostly for German rieslings, but the "kabinett" ones, which are dryest... I also enjoy rhône varietals from california and rieslings from Washington state...
Vin jaune (yellow wine), from Arbois, in France, is also a favorite, though I have it only rarely... Very particular wine...
Champagnes: definitely the Tainttinger or the Roederer, the regular, not the Cristal... I might add that the California Roederer is aslo very good, though it trades the characteristic "wet hay" champagne taste for something more citrusy...
