Hard to choose a favorite - as they are all pretty good on their own. If I had to pick by a sub-catagory, it would look something like this:
Non-alcoholic:
Soda - Coke branded products, diet or regular
Tea - just about any oriental tea (flowers, leaves, roots, etc.)
Coffee - not a big coffee fan, unless it is the good stuff. Ones that I liked include Kona coffee (picked up some in Hawaii directly, it really does taste
different) and some of the seasonal gourmet varieties from Gevalia. Expresso, Lattes, etc. - doesn't work for me anymore - probably due to coworkers always dragging me down to have a "working" coffee break at Starbucks.
Just plain water, no "fitness" water or "imported, spring water"
No Milk - I drink Soy or Rice milk
Orange juice - only one that I will drink more once a week
Alcoholic:
Wine - Not a big fan of wine, unless it is homemade. Same with champagne
Beer - No favorite beer, probably due to the huge number of good, smaller microbreweries where I live at - I tend to prefer darker, beers - stouts, porters, brown ales, and Belgian ales. Not too many, as these are generally loaded with calories, some can be considered meal replacements.
Liquor and Spirits - all good - I stick will classics, of the liquors I tend to stick to these
scotch - good single malt scotch (Macallan or Lagavulin)
vodka - local Virginia variety Cirrus Vodka is really good and inexpensive to boot and the premium XO Vodka for flavor
tequila - Jose Cuervo Reserva de la Familia or Patron Reposado (almost like a rum)
rum - Havana Club Barrelproof or Bacardi Reserva
