England
The folks at London-based Myatt's Fields Cocktails turned to their also London-based friends at Monmouth Coffee for this pre-bottled Espresso Martini! Alongside said coffee, a blend of vodka and coffee liqueur go into the classic serve. Make sure you give this one a very good shake before serving!
Fresh espresso, bittersweet coffee bean, a touch of brown sugar.

Perfect espresso martini, just a shame I can't make it last longer! Will buy again and again.
