A friend recently urged Tihany to visit the wineries of Malibu. “I didn’t even know they existed!” the designer says. Indeed, the beachside enclave produces some impressive wines thanks to its Sonoma-like climate. These spots—suggested to the designer by Alex Weill, the sommelier at Bouchon in Beverly Hills—make a great day trip. Rosenthal-Malibu Estate (26023 Pacific Coast Hwy.; 310/456-1392), founded in 1987, is considered the area’s best winery. At Malibu Family Wines (31740 Mulholland Hwy.; 818/865-0605) you can sample Syrah and Pinot Noir from Semler Saddle Rock Estate Vineyards. Finally, the tasting room Sip (2598 Sierra Creek Rd., Agoura; 818/865-0440) sells its own Cielo Estate, a rich Cabernet Sauvignon grown just outside.
