If you've never been to one, go. If you have a favorite barista, he or she will be there. It's the most energetic coffee-slinging event you've never heard of. Open to the public, latte-art throwdowns are well known in the coffee community, but wildly undiscovered by lesser humans (aka non-baristas). Structured with a bracket system, baristas go head-to-head, facing off to see who can pour a better heart, rosette or some other form of latte art. Winners move on to the next level, and in the end there is only one latte-art champion. People yell and jump and talk mad shit, and it's wonderful. Nobody takes it very seriously, but there are seriously talented people competing. Held at coffee shops around the city; keep your eye out for a flier at your favorite java joint.
