While water inspires the cuisine, ice inspires the cocktails at Riffle, a new restaurant in Portland, OR. Riffle has installed an ice machine that creates 400-pound blocks of crystal clear ice that are traditionally used for creating ice sculptures. After 3 months of extensive testing, these giant blocks are destined for your drinks, whether carefully carved into crystal-clear spears to fit into a Collins glass for the Riffle Collins made with fresh celery juice, or a hand-cut sphere for the old-fashioned inspired Mayor Rock cocktail, comprised of mezcal, applejack, agave, and bitters. Dave Shenaut, former president of the Oregon Bartender's Guild, has bounced around for brief stints at almost all of Portland's greatest craft cocktail bars. But he told us that he won't be leaving Riffle anytime soon.
