I'm 23 years old and I'm building my liquor shelf. I have a large shelf in my bedroom with:
Jameson Whisky, Baileys, Kailua, Gin, Tequila, Rum, Vodka, Strawberry Vodka, Vermouth, some Root Beer Schnapps, and some sweeteners like Grenadine. Garnishes are in the fridge.
That's still growing, and I'm trying a new mixed drink every week. Last week was different kinds of Martinis (Gin, Vodka, Apple...). This week, the Manhattan.
I started my collection from an image of a manly-man having not only a good liquor collection, but a knowledge of every classic drink, several party drinks, and a few unique ones with stories behind them.
