Calcareous Vineyard

Calcareous Vineyard

Some of the best parts of the Paso Robles wine country are the many backroads of the area that lead to fantastic vistas and out-of-the-way wineries. You can visit all the wineries on the “Hidden Wine Trail Westside” over one or two days, or combine a visit to one or more of these wineries with the other two wine trails on the west side of Highway 101. Take it slow and always pack a lunch for a great picnic time on this wine trail. This trail goes in a loop starting and ending in downtown Paso Robles.

Our selection of the best hidden wineries on the westside

• Rotta Winery – Started in 1908, oldest family-owned winery in Paso
• Westberg Cellars – Don’t pass up the Turtle Rock
• Pipestone Vineyards – Sustainable and organic vineyards
• Dunning Vineyards Estate – A good find at the end of the road
• Calcareous Vineyards – Beautiful Rhone styles wines, spacious tasting room

Winery Descriptions, Driving Directions, Tasting Room Hours

Rotta Vineyards
The first stop will be the oldest winery in Paso Robles with a start date of 1908. The original family’s descendants still operate the winery today. The tasting room is very cool, with displays of some of the old jug wine bottles. There are many good red and white wines to try, but we especially like the Rotta Zinfandel wines. To get to Rotta, leave downtown Paso Robles, heading south on Spring Street. Take the ramp onto 101 South and then take the exit for Las Tablas Road. Turn right onto Las Tablas Road and then a left on Winery Road.

Tasting room open daily 10 to 5,

Westberg Cellars
We recently received word that Westberg Cellars has closed its doors and is no longer in operation.

Pipestone Vineyards
Leave Westberg and continue north on Willow Creek Road, take the first right onto Las Tablas Willow Creek Road. Take the first left onto Niderer Road. Stay on Niderer and the Pipestone entrance will be on the left. At Pipestone Vineyards, you will find a small family-owned winery run by Jeff Pipes and his wife Florence Wong. They are dedicated to sustainable and organic farming. No chemicals or pesticides are used. The entire vineyard has been designed using the principles of feng shui. The wine production is small and the emphasis is on Rhone style wines. These include estate wines of Viognier, Grenache, Mourvedre, and Syrah.

Tasting room open Thursday to Monday, 11 am to 5,

Dunning Vineyards Estate Winery
Just up ahead on Niderer Road is Dunning Vineyards. This is another small family-run winery. In contrast to Pipestone, Dunning Vineyards makes only one Rhone style wine, a Syrah, while the other wines include Chardonnay, Cabernet Sauvignon, Merlot, and a Meritage blend. The winemaker is owner Robert Dunning, who you will likely find pouring your wines in the tasting room.

Tasting room open Thursday to Monday, Phone: (805) 238-4763

Calcareous Vineyard
This winery is named after the type of soil that is found in this area of Paso Robles. It is similar to soils found in the Rhone region of France, and thus the emphasis at Calcareous on Rhone style wines. The tasting room is vast and the views panoramic. This is a great spot for a picnic lunch, or a chance to just relax and take in the views while sipping a nice chilled glass of Marsanne. To get to Calcareous from Dunning, you have a couple of choices. This route is a little longer but has better roads. Go back along Niderer Road, turn right onto Las Tablas Willow Creek Road. Keep left at the fork and turn right on Peachy Canyon Road. Continue for about five miles and then look for the signs to Calcareous.

Tasting room open daily 11 to 5
