Liquor store is literally 30 seconds walk from home so never a major concern, but I'll typically have at least one each of: cognac, port and grey goose around, occasionally a nice Havana Club too.
I used to always have a few bottels of spirits and wine.. However my poor student status doesn't allow this at present. Once I am working again, gin and whiskey are a required staple, as are a few bottles of red.
Current stash, bolstered by having just had a birthday:
1 x 12 box Steinlager Pure
1 x bottle Jager
1 x bottle Makers Mark
Various minibar bottle selection emergency stash.
About 3 bottles of vodka (x1 belvedere, x2 42 below(one plain, one feijoa)
1 bottle peach schnapps
1 bottle of apple sours
2 bottles of malibu
3 other liquers I dont know the name of.
1/2 box of steinlager pure
some artisan beer
I'll be having cocktails & beer when the world ends.
Not only do I have a strategic reserve, but I planned ahead and have a lime tree in a pot just outside the front door. no point having vodka if you've got no lime.
