Preparing a cup of tea is raised to high art in a traditional Japanese tea ceremony. Those who have never been to one will get a chance to experience the ritual at the free Sonoma County Matsuri Festival. In its tenth year, the festival will showcase many aspects of Japanese culture, including mochi pounding, Japanese storytelling, taiko drumming, folk music and dancing, and treats like matcha popcorn. The festival will be held on May 19, 11 a.m.–5 p.m., at Juilliard Park in Santa Rosa. Go to sonomamatsuri.com for a complete schedule of events.
