The next Latte Art Throwdown will be held Oct. 20 at Coffee by Design at One Diamond St. in Portland.

Baristas from all over Maine and New England compete every few months to create the best heart, rosette or other design on top of a cup of latte. Contestants pay $10 each to compete, and the champion wins half the participation fee. The other half is donated to a nonprofit, this month the East Bayside Community Mosaic Mural Project, which is sponsored by the University of Southern Main Art Department’s Artist in Residence program with Senegal-based artist Muhsana Ali. The artist, USM art and social work students, and community members are creating a large mural of glass, mirror and tile on the back of Coffee By Design, across from Kennedy Park.

The throwdown will begin with a practice round at 7 p.m. The contest, which is free and open to the public, begins at 8 p.m.
