If I'm drinking for enjoyment, some sake, plum wine, or a nice beer are great. Darker porter/stout beers like Guinness are my favorite, but I like some lighter beers too like Kona Brewing Co. or Kirin. I'm not too picky if I have to deal with something cheaper unless it tastes like lighter fluid.
Hard liquor's great too, but I get drunk easy so I can't have as much as I'd hope. I prefer the kick in the ass, so I usually drink liquor neat or on-ice. I have a hard time finding a go-to cocktail, but caipirinha, gin & juice, Irish coffee, and mojitos are pretty good.
As for which one's I enjoy, it'd have to be rum, gin, whisky/scotch, and tequila. Almost everything except vodka. Some favorites include Barbancourt, Hendricks, and Suntory.
