Santa Maria Valley: a visitor's guide to the county's oldest AVA

The Santa Maria Valley is the oldest of the seven American Viticultural Areas we cover in Santa Barbara County, established almost two years before the next, the Santa Ynez Valley. Here is what the federal record says about the valley, and where you can taste its wine today.

What the AVA is

The federal government established the Santa Maria Valley AVA effective September 4, 1981. The boundary is in the Code of Federal Regulations at 27 CFR 9.28.

About 90 percent of the growers in the area signed the petition. At a public hearing in Santa Maria, witnesses described a long farming past in citrus and avocados, and said grapes arrived as a crop around 1970.

The area reaches into San Luis Obispo County as well as Santa Barbara County. Its edges are easy to picture: U.S. 101 on the west, Highway 166 to the north, mountain summits to the east, and Foxen Canyon Road down to the community of Sisquoc on the southern side. For the outline on a map and every listing inside it, see the Santa Maria Valley page.

What makes it distinct, per the record

The rule calls the valley funnel-shaped. Land runs from about 200 feet where U.S. 101 crosses the Santa Maria River up to about 3,200 feet at Tepusquet Peak. In 1981 the vines grew on the valley floor at roughly 300 feet and on slopes up to about 800 feet. The soils are well drained, from sandy loam to clay loam.

Then there is the ocean. Witnesses said prevailing winds off the Pacific give the valley a cooler summer, a warmer fall and a cooler winter than the areas around it. The choice of U.S. 101 as the western edge rests on fog: witnesses said the fog line sits just west of the highway, where the fog lingers longer and winters lack the chill the vines need to go dormant.

The rule names no grapes. It also says that approval marks the area as distinct, not its wine as better.

What the places we list pour

We hold no current source for what is planted in the valley, so we stick to what our listings name. Of the 13 places we list with a home in the AVA, 11 name Chardonnay and 11 name Pinot Noir. Syrah comes next with six. Chardonnay in the Santa Maria Valley and Pinot Noir in the Santa Maria Valley put those places on one page.

Visiting inside the valley

Nine of the 13 welcome visitors, all with a Santa Maria address. None of them tells us walk-ins are welcome, so plan to book. Hours are as each place posts them:

• Riverbench Vineyard & Winery, Foxen Canyon Road: daily 10am–4pm. A reservation is recommended.
• FOXEN Vineyard & Winery, Foxen Canyon Road: daily 11am–4pm. A reservation is recommended.
• FOXEN – The Shack, Foxen Canyon Road: Friday to Sunday 11am–4pm. A reservation is recommended.
• Rancho Sisquoc Winery, Foxen Canyon Road: Thursday to Monday 10am–5pm. A reservation is recommended.
• Tres Hermanas Vineyard & Winery, Foxen Canyon Road: weekdays 12pm–4pm, weekends 11am–5pm.
• Presqu'ile: open every day except Tuesday. A reservation is recommended.
• The Gatehouse at Bien Nacido: Thursday to Monday 11am–5pm.
• Paul Lato Wines: by appointment only, at set times six days a week.
• Ranchos de Ontiveros: a reservation is required. We do not hold its hours yet, so check with the winery.

The first five all have a Foxen Canyon Road address, and our Foxen Canyon Road plan takes them north to south. On a Tuesday, Riverbench, FOXEN's main tasting room and Tres Hermanas are the ones with posted hours.

Pouring Santa Maria Valley wine elsewhere

Twenty more places we list pour wine from the valley without being in it. Five are in Los Olivos, four each in Buellton and Lompoc. Five of the 20 welcome walk-ins:

• Hitching Post Wines, Buellton: Wednesday to Sunday 11:30am–5pm.
• Liquid Farm, Los Olivos: daily from 11am.
• Lucas & Lewellen Vineyards, Solvang: daily 10am–4:30pm.
• Flying Goat Cellars, Lompoc: Thursday to Monday.
• Sweetzer Cellars, Lompoc: Friday to Sunday 11am–5pm.

The last two are on our Lompoc Wine Ghetto walk. In Santa Barbara itself, Riverbench keeps a second tasting room, open daily until 7pm.

Not every bottle in these rooms is from the valley. Ask which ones are.

Plan it

Start on the Santa Maria town page for the map, then add your stops to My day. The planner checks each one against its posted hours for the date you pick.

A note on these numbers

We counted on October 13, 2026, from our approved listings, each checked against the winery's own website. "In the AVA" means the listing's home sits inside the boundary: 13 places, nine of them open to visitors (eight say so, and Presqu'ile posts open hours). "Pours its wine" adds 20 more whose own sources show Santa Maria Valley wine, for 33 in all. The AVA facts come from the 1981 federal rule and the current regulation listed below.
