Speed Rack, one of the biggest cocktail parties thrown in Seattle last year, is back.

This three-hour cocktail contest, Sunday (Feb. 16) at Century Ballroom, is a fundraiser for breast-cancer charities. It pits the top female bartenders from Portland to Vancouver, B.C., in round-robin competition to see who makes the best booze under pressure. Each contestant has to make four drinks in five minutes.

Popular around the country, Speed Rack first came to Seattle last winter and drew a crowd of 350. After that success, organizers say it was a no-brainer that the contest would make a stop in Seattle again, maybe every year now.

The event usually morphs into a party that lasts for days. Last year, Speed Rack became a weeklong event as booze reps flew in to Seattle for this fundraiser and stuck around to sponsor other parties and $5 happy-hour specials in Belltown and Capitol Hill.
