Off the top of my head, I know that my home bar has:
Scotch Whisky: Ardbeg, Lagavulin, Laprhroig, Macallan 12
Irish Whiskey: Jamesons
Bourbon: Maker's Mark
Not Bourbon: Jack Daniels
Rye: Old Overholt, Bulleit
Canadian blended whiskey: Crown Royal
Tequila: Don Julio anejo, Espolon blanco, Espolon anejo, Cazzadores reposado
Vodka: Tito's, Dripping Springs Ruby Redbird (grapefruit)
Not vodka: Bombay Sapphire gin, Hendricks gin
Rum: Appleton Estate Reserve, Bacardi Gold
Cachaca: Leblon, Pitu
Cognac: Hennessey XO (this one was a gift), Remy Martin VSOP
Pastis: Ricard
It sounds like a lot, and there are probably a handful more, but like I said earlier, I like to host the occasional nostalgic Cocktail Party, and I like to have a variety for that. I really, honestly don't drink much hard liquor so my bottles tend to linger for a while. The Scotch, gin, and tequila are what I go through quickest.
