I drink occasionally, although the long term medication I'm on says to avoid alcohol altogether.
I like some wines, and Bailey's/Amarula type liqueurs. I also like fruit ciders, Crabbie's Ginger beer, schnapps, sherry and port.
My OH likes sweet wine, fruit ciders and single malt whisky. He also only drinks occasionally.
Now for my confession: 
I seem to have a bit of an obsession with collecting bottles of alcohol, so my collection is pretty large and wide ranging, and includes things that we don't really drink.
I'm a sucker for a good description or unusual bottle too!
Tbf, I was always brought up that you have things availible/cater for guests, but as we don't have very many, my collection just gets bigger!
I have around 130 bottles including:
Kraken spiced rum (loved the bottle and description, but haven't tried it & don't think I'd like it)
Cognac (never tried it)
Brandy
Gin (don't like it)
Flavoured vodkas (again we don't drink vodka, but they sounded nice & others will)
Various fruit liqueurs eg, orange, cherry, raspberry, etc.
About 30 bottles of red, white and rose wines
About 15 bottles of sweet liqueur wines including Tokaji, red and white Muscat, semillon, and eiswein
About 30 bottles of various single malt whiskies (Jura, Glenmorangie, Oban, etc)
Various ports ranging between 10 and 40 years old and various bottles of sherry (probably about 15 bottles altogether)
Malibu
Various bottles of schnapps
Tia Maria (yuck!), Cointreau, Bailey's, Amarula, and various other drinks.
Also I have various ciders, alcoholic ginger beers, some craft beers (for a friend) and wine for cooking.
I'm going to have a party next summer, so I will hopefully use up a lot of it then (and can then start collecting again
).
