Japanese inventor Hiroshi Tanaka and his American partner, Edward Alexander, put on a demonstration at something called Taste3, "A conference for wine professionals," in the Napa Valley in July (anybody aware of this event?) where it seemingly impressed the "professionals" including Joshua Wesson, chairman of the Best Cellars chain of wine stores, who told The Times that his experience with the device was "mixed," but acknowledged that he tasted one red that “softened fairly dramatically - was rounder, less tannic."
