This week's cocktail — which we could really use one of right now, can I hear you say YEAH, SFist readers? TGIF! — comes from the bar consultants at Quince, Scott Baird and Josh Harris, who created a clean and refreshing drink for their cocktail menu that may as well be a classic. From Scott:

This drink is all about the balance created by not boozing it up too much, rather, we wanted to see the vermouth shine with its appetite wetting herbacious bitterness, and let the 12 years on wood bourbon interact with the toasty champagne to give the guest an aperitif with complexity but without an overly alcoholic punch. A Lambretta is the Ferrari of motor scooters, and they have elegant, classic lines. We felt that the drink was a great way to start an amazing meal on a cold San Francisco night at Quince.

La Lambretta

1.25oz Carpano Antica Formula Vermouth
0.75oz W.L. Weller 12 year old bourbon
0.5oz Campari
0.5oz Lemon Juice
2 oz Champagne (has to be the real thing, the yeastier and bready-er the better)

Mix all the ingredients with the exception of the champagne in a mixing glass or mixing tin add ice and shake. Double strain drink through a tea strainer into a champagne flute. Measure and pour the champagne in and garnish with an amarena cherry.
