The inventive bar program at Jasper’s Corner Tap & Kitchen (401 Taylor Street) in San Francisco features several cocktails that are actually served out of a draft system. It’s a relatively unique innovation that’s been turning heads at this popular downtown bar since being introduced last year.

The first drink to come out of the lines was their Plymouth Gin and Campari-based Negroni. Next up was a distinctly San Franciscan fusion known as the Hanky Panky. In addition to the juniper-laced tones of Tanqueray and sweet Vermouth, bartenders threw in a touch of Fernet. This bitter, aromatic Italian digestif enjoys an almost cult-like adoration in the Bay Area and adds a curious herbaceous underpinning into the mix.

This week Jasper’s introduces the newest addition to their tap cocktail lineup: The Grand Promenade a Wild Turkey. While it’s name might be more than a mouthful, the drink itself is easy to swallow. With an eclectic combination of distinctive spirits, including Wild Turkey Rye 81, Bonded AppleJack, Benedictine and Yellow Chartreuse, this unexpected libation brings a cavalcade of flavor to the palate. The trademark spice and fruit characteristics of the rye are invigorated by the sweetness of the AppleJack yet the overall effect is sophisticated thanks to the herbal enhancement of the French liqueurs.

Served on the rocks with a twist of orange, the Grand Promenade is an exquisitely well conceived cocktail that is reasonably priced at $9, considering the exclusive nature of the ingredients—particularly the Chartreuse. It’s definitely worth a taste on your next visit to this hip watering hole that is doing its part to stay on the cutting edge of mixology.
