Say the words “California wine” and more often than not, bruiser Napa Cabernets or buttery Sonoma Chardonnays come to mind. There’s a certain irony to the fact that most consumers consider wine country of Santa Barbara County as a relative newcomer when in fact the area has had acreage under vine for over one hundred years. But it wasn’t until the 1980s that Santa Barbara County really took off, thanks in part to the UC Davis’s assessment of it having the optimal climate for growing grapes.
What makes the climate of Santa Barbara County and the Central Coast so unique? Three factors come into play: The Humboldt Current, the Coriolis Effect, and the Transverse Range.
The Humboldt Current, despite its name, has nothing to do with cheese or green pharmaceuticals. It’s actually a deep ocean current that comes up from Peru, bringing cool waters with it. That combines with the Coriolis Effect, which is a phenomenon that occurs when northern winds push surface-warm ocean water off the top of the Pacific and moves it further west. The Coriolis Effect truly is phenomenal because it’s not possible without the Earth’s rotation! When that warmer water shifts away, those deep, cool waters shift towards the top, ensuring a continuous cooling effect mid-California Coast. That cool air is then funneled inland due to the Transverse Range: that’s where the North-South running mountains turn East-West due to an early plate tectonic shift. That geological and meteorological combination add up to the unique microclimates we find around Santa Barbara County – which add up to a great variety of wine!
The two biggest AVAs, or American Viticultural Areas, in Santa Barbara County are Santa Maria Valley and Santa Ynez Valley. Both are river valleys created by that plate tectonic shift, which means they oddly run west-to-east, funneling cool maritime air in with them. Both AVAs benefit from large diurnal swings because the cool Pacific influence brings in chilly fog overnight, lowering the nightly temperatures, before burning off midday at higher, hotter afternoon temperatures. That large temperature swing optimizes sugar levels in grapes while maintaining acidity. You’ll notice wines from both AVAs may be higher in alcohol but never taste out of balance: there will always be a refreshing prickle of acidity on the finish. Let’s take a moment to thank diurnal swings for that!
Within the Santa Ynez Valley AVA, the best known AVA is Sta. Rita Hills. (And yes, it is legally ‘Sta. Rita Hills’ and not ‘Santa Rita Hills.’ It seems the famous Santa Rita winery in Chile was a bit peeved when the Santa Rita Hills AVA was initially granted and sued to prevent consumer confusion.) Sta. Rita Hills is most famous for its Pinot Noir. The AVA benefits from that ocean air as well as very specific ‘chet’ soil that create the unmistakably bright and floral Sta. Rita Pinot flavor. It’s no mistake that some of the best-known California Pinot vineyards, including Sea Smoke, are located here.
Moving away from the ocean, we find the Ballard Canyon and Happy Canyon AVAs. As their names imply, they are both lower altitude AVAs and, since they’re surrounded by mountains, heat and sunlight reflect off to create much warmer microclimates than those found in Sta. Rita Hills. Bordeaux and Rhone varietals do well here. In particular, Cabernet Sauvignon loves Happy Canyon and Syrah rules Ballard Canyon.
And, fun fact!: Happy Canyon earned its moniker by having the only working still during Prohibition, leading many a local to visit and to leave quite happy! We’re pleased to see this happy-making legacy continued with fantastic wine.
And finally, the newest AVA in the region is perhaps the closest to our heart: the Los Olivos District. Located in the area surrounding the Los Olivos Café, the Bernat vineyard is proud to be part of the Los Olivos District. Comparatively flat and warm, Syrah absolutely thrives here – which you can taste in the many different Bernat Syrah bottlings.
With the continued interest in Santa Barbara County, we feel that its potential is just now being brought to fruition. The various microclimates and unique topography allow for infinite possibilities, from rich, round reds to bright, acidic whites. Santa Barbara Country truly has a wine for every wine lover!
