Judd’s Hill Winery begins a festive and philanthropic tradition with the Judd’s Hill Musical Bonanza April 14, noon until 4 p.m. at the winery’s new location, 2332 Silverado Trail (between Hardman & Trancas). Tickets are $85 per person for the public and $70 for Judd’s Hill Wine Club members (and you can join at www.juddshill.com).

The Finkelstein family, the owners of Judd’s Hill, is known for its commitment to the arts, and accordingly, the event will benefit Arts Council Napa Valley. Wine Club members will receive a 20 percent discount on wine they purchase at the Bonanza.

“It will be a sensational day of wine, food, music and fun,” Judd Finkestein said, “and we’ll also be celebrating the release of our 2005 Old Vine Zinfandel.

Judd’s band, the Makai Gents Featuring the Mysterious Miss Mauna Loa, will perform, along with the San Francisco tropical rock band APE  and King Kukulele from Los Angeles, a comedic ukulele player. A barbecue feast will be served throughout the day; the winery’s current releases will be available for sale and to taste.
