Last week, some of San Francisco's best bartenders faced off in one leg of what is sure to be one of the most high profile cocktail competitions in the country. Sponsored by Domaine de Canton, that spicy, complex and delicious ginger liqueur that debuted earlier this year, the contest is worth $10,000 to the ultimate winner and a trip to St Martin for the finalists. Considering all that, you would think tensions would have been high at Le Colonial, where the event was staged. Rather, though, the mood was festive and the bartenders didn't act as if they were nervous at all. Drink ingredients varied from coffee beans and kaffir lime leaves to coconut milk and pineapple.
