We all know about Napa. But what about the rest of California? From scenic Shasta to sunny San Diego, California produces 90% of the nation's wine -- and does it well. Truth is, some of the world's best wineries can be found all throughout the Golden State.

If you're looking to break away from the central tourist hub of the California wine industry, or you're seeking to explore some of California's lesser known hot spots, check out these seven wine regions around the state.

What's more, is that most of California's wine regions beyond Napa are far more affordable, too.

1. Santa Barbara

Santa Barbara is the star of southern California wine tasting, with more than 275 wineries fueled by a climate ideal for growing cool-climate grape varieties like Pinot Noir and Chardonnay. The region's vineyards are located in the Santa Ynez Valley, which is cooled by breezes from the Pacific Ocean, resulting in wines with elegant flavors and aromas. Most wineries are smaller, family-owned boutique wineries.

To get to the Santa Ynez Valley from downtown, expect about a 45-minute scenic drive through rolling vineyards of the Santa Ynez and Santa Maria Valleys. Once there, most wineries are free to visit, though you’ll usually pay per tasting (wine flight fees usually cost between $15 and $30, depending on the winery). Sometimes fees are waived with purchase.

If wineries aren't your thing, (or you just want to fill your day with more activities than simply wine tasting) there's plenty else to do in the Santa Ynez Valley and the broader Santa Barbara County. That includes Santa Ynez Valley's charming neighbor of Solvang, which is a charming Danish-inspired village known for its unique thatched roofs and windmills. Don't leave without trying the Aebleskiver, which is a puffy Danish pancake).

If you're visiting Santa Barbara but can't make it out to the Santa Ynez Valley, you can still get a taste of the region's wine scene without trekking too far. That's thanks to the Santa Barbara Urban Wine Trail, which is a series of tasting rooms that are mostly located within walkable downtown Santa Barbara. And you might very well contain your trip almost entirely to the downtown area, as it's home to some of the nation's best beaches, a stunning, historic courthouse, funky art and no shortage of tacos.

To get there, many folks fly into Los Angeles International Airport (LAX) and drive about two hours. But if you can, try flying into the smaller Santa Barbara airport, which is delightfully charming.

2. Sonoma County's Kenwood region

Sonoma is a neighbor to Napa, and in many ways, it's better. In fact, many of the locals prefer it. Sonoma has a more relaxed and laid-back atmosphere than Napa, its wineries are less crowded, and — unlike Napa's endless array of Michelin-starred restaurants and luxury hotels — Sonoma is more affordable and accessible.

One of Sonoma's top cities is Kenwood. There, you'll find not just wineries but plenty else to do, including the nearby Sugarloaf Ridge State Park. There, you'll find miles of trails, a waterfall, Bald Mountain and the Robert Ferguson Observatory. to the south is Wildwood Nursery, whichfeatures sculptures scattered on trails throughout five lushly-forested acres, plus more than 250 varieties of Japanese maples, dogwoods, ginkgos, conifers, edible plant starts, and bonsai-style beech, maple, and evergreen trees.

As far as where to stay, the most luxury option (without the luxury price tag at Napa's highest-end hotels is theKenwood Inn andSpa. The Mediterranean, villa-style resort doesn't skimp on amenities. There's a gourmet breakfast every morning where you can pick your choice of entree (no heat lamps and everyone touching the same egg buffet platter here). In the evening, there's a wine hour featuring savory bites that you could practically make a meal out of. And hot, fresh cookies are served throughout the day.

3. Sierra Foothills

Specializing in full-bodied red wines, the Sierra Foothills are somewhat isolated from the other California wine regions and contain some of the state's oldest producing vines. It was here where Zinfandel originated, and many of the area's wineries produce a renowned "Big" Zin.

Nicknamed the "Gold Country," the Sierra Foothills harbor a rich mining history. The region attracted a great number of fortune-seekers during the California Gold Rush of the mid-19th century. Fun fact: Amador County in the Gold Country was California's only county to actually expand vineyard acreage during prohibition years.

4. Sonoma County's Russian River region

Part of the Sonoma Valley, Russian River is California's second most popular wine region. The area measures nearly 200 square miles, containing more than 80 wineries. The region is most known for its cool-climate varietals -- namely Chardonnays and Pinot Noirs.

Russian River contains an eclectic variety of wineries, from family-owned establishments to big conglomerations. Close to San Francisco, it makes a fantastic addition to any Bay Area vacation. Driving tours are available and offer a gorgeous cruise through the rolling hills, small towns and charming wineries that characterize the region.

5. Livermore Valley

An hour east from San Francisco, the Livermore Valley boasts a rich history of grape-growing and over 130 years in the winery business. Spanish missionaries planted the first grapes in 1760, and the first commercial vines sprung up in the 1840s.

In 1889, Livermore won America a gold medal at the Paris Exposition, bringing California wine worldwide attention. The Valley was the first place to bottle varietal labeled Sauvignon Blanc, Chardonnay and Petite Sirah. Supposedly, almost 80% of the state's Chardonnay vines have genetic roots in Livermore Valley.

6. Clarksburg

Nestled in the Sacramento River Delta, Clarksburg is marked by beautiful landscapes of crisscrossing sloughs, swing bridges, drawbridges and, of course, fecund vineyards. Summer in Clarksburg is nothing short of idyllic, the days warm and the night cool. With 10,000 acres of vineyards, the region produces over 25 varieties of wine grapes. Clarksburg is essentially a collection of small towns, wineries, wine shops, vineyards, classy restaurants and sparkling waterways.

7. Paso Robles

Between Los Angeles and San Francisco on California's Central Coast, Paso Robles is a sprawling 26,000 acres of vineyard with more than 40 wine grape varieties. Not only is the region large and diverse, but it is near a number of worthwhile travel destinations.

The historic downtown area is home to a number of upscale wine shops, restaurants and boutiques. The famous Heart Castle is not far north, and breathtaking California coast is not far off. The landscape of Paso Robles is diverse with river beds, rolling hills and picturesque mountains.

8. Santa Cruz Mountains

The Santa Cruz Mountains Appellation was the first wine-growing region in the nation defined by a mountain range. It stretches from Mount Madonna to Half Moon Bay with a minimum ocean-side vineyard elevation of 400ft.

Many of the vineyards boast astounding views of the coastline. The cooling ocean breeze and air from the San Francisco Bay create ideal grape-growing conditions. Though the region contains more than 70 wineries (most of them family-run), the Santa Cruz Mountains do not produce large quantities of wine. But what they do bottle is both distinct and sophisticated.

9. Mendocino

The Sea Rock Inn overlooks the Pacific Ocean in Mendocino.

A couple hours north of San Francisco, Mendocino is easily one of the most scenic regions in all of California. A beatific melange of rocky coastline, inviting beaches, lush hills and cozy villages, the region even houses multiple state parks. In addition to acres upon acres of vineyards, you can enjoy redwood forests and majestic landscapes.

Visitors even have the chance to catch a glimpse of migrating whales. Between wine tastings, you can go for refreshing hikes, visit organic breweries or walk along the beaches.
