This smooth and tart winter delight is basically a Boston Sour, where the bourbon has been infused with grapefruit peel. I sampled this drink in Vancouver at West Restaurant, where the bar program is ably commanded by award-winning mixologist David Wolowidnyk.
As you know by now, I really like sours, and it’s neat to see more bartenders playing around with grapefruit in this style of drink. This version is light and lemony, with a lip-puckering kiss from the grapefruit and an affectionate slap from the bourbon. Be careful though — after one sip you might end up in a race to the bottom of the glass.
Grapefruit meets bourbon in this tasty twist on a Boston Sour at West Restaurant in Vancouver.
