(TheDrinksBusiness) - Charles Krug Winery in St Helena, California, will attempt to break the world record for the longest relay wine toast this Sunday. Dubbed the “Napa Valley Wine Wave”, the wave must be a sequential toast where participants clink glasses in order from start to finish, rather than everyone clinking glasses simultaneously. An official Guinness World Records adjudicator will announce whether the new world record has been set and, if successful, participants will receive a medal to commemorate the event.
