"Kanpai!" You may hear a few attendees joyously exclaim this Japanese phrase, equivalent to the English "Cheers!" at the fifth annual Northern California Premium Sake Fest. The event kicks off Wednesday at The Sheraton Grand. North American Food Distributions — importer and wholesale distributor for Asian food retailers — hand-selected over 100 of the finest sake, shochu and Japanese beers to be presented and tasted for this event. "Shochu is a distilled spirit," said Judy Inaba, event manager for North American Food Distributions Inc. "It is an old-style beverage, very popular in Japan." The drink can be mixed with different juices, much like vodka, for a desired taste, Inaba said. Ea
