State-of-the-art Facility

Riboli center


Our new Paso Robles winery features several sizes of both closed and open-topped tanks, which gives us the flexibility to separate individual vineyard lots to accommodate the different varietals and clones in our estate vineyards.

Tank facility

Water treatment

To conserve water, the winery is air-cooled and the building structure has been designed with complete insulation. Storm and waste water is processed and reclaimed for onsite irrigation needs using a membrane bioreactor. In the first year, over 1 million gallons were processed – all of which has been reused for irrigation without any release into the sewer.

Water flowing into hand


Our state-of-the-art winery is powered entirely by solar energy from the solar panels that cover 80% of the rooftop. This energy source provides 100% of our electrical power needs.

Barrel Aging

The oak barrel room can be divided into four areas where wine can ferment and be stored at varying temperatures depending on the vintage and varietal. Automated ceiling fans allow the cooling system to utilize Paso Roble’s famously frigid overnight temperatures for temperature control.
