Tia Maria

Picture the espresso martini you'd actually drive across town for. That's this in a bottle. Cold-brewed Arabica coffee, soft Madagascan vanilla and a rum base, all riding at a gentle 20%. Pour it over a single big ice cube after dinner and it drinks like a grown-up coffee that happens to give you a hug. Shake it with vodka and a shot of espresso and you've got the cocktail that ends every good night out. Litre bottle, so you're not running dry mid-party.
