B Cellars Sustainability

Learn More About Our Biodynamic Winery in Napa Valley

At B Cellars, we are always looking for ways to minimize our environmental footprint and strive to go beyond the expected. From sustainable farming practices to our environmentally conscious operations and standards for community well-being, we constantly are in search of new opportunities for sustainable innovation.

Read on to learn more about B Cellars’ full range of sustainable practices.


  • The majority of the food we serve is grown on site. We have stone fruit orchards, olive trees, culinary gardens, and a hen house.
  • On our property, we have a large bee apiary. This contributes to the health of the vineyards and strengthens the local bee community.
  • The landscape of our vineyards relies on combinations of drought-tolerant and native tree species to provide shade, protection from the wind, and to create a more comfortable microclimate.
  • By incorporating orchard trees and flowering ornamentals into the landscape, we are able to facilitate the pollination of adjacent vineyards while maintaining our agricultural quality.
  • We utilize a variety of native grasses and wildflower mixes to alleviate the need for irrigation, secure slopes, provide animal habitat, and further facilitate the pollination of larger areas.

Water Use:

  • We make use of the Lyve System. This system is a biological process that repurposes water used in the production of wine. Water used in the Production Building and Winery Caves is collected and connects to the Lyve System where its biologically treated. This water is then held in underground storage tanks to be used for irrigation.
  • We also employ the Hoot System—a complex filtering system—for waste water disposal at the winery. After the water is filtered, its then dispersed back into the ground as irrigation quality water.

Energy Use:

  • The Hospitality House and its outdoor spaces are shaded by large overhangs and pergolas. This keeps the building and surrounding areas cooler and reduces energy use as a result.
  • The Hospitality House and Production Buildings utilize concrete flooring, which provides critical thermal mass during the winter months.
  • Our winery caves provide natural cold storage for barrel aging wine, thus minimizing the need to condition on- or off-site storage facilities and related transportation.
  • We have an on-site electric vehicle charging station, available for guest access and able to accommodate two vehicles at a time. A second charging station can be found in the employee parking area.


  • We repurposed the trees cleared on the property during construction to be used as flooring and furniture.
  • The cave spoils from the cave excavation process were repurposed for site grading and landscaping.
  • We are committed to employing an extensive recycling program for all of the consumables used in the winery.
  • We employ a natural paving system that exceeds highway specifications for asphalt. It consists of decomposed granite with a G5 stabilizer and is green, sustainable, and allows for LEED accreditation and carbon credits.
  • Our buildings were designed and constructed to accommodate solar energy. Our five-year plan includes completing the installation for all facilities.


  • We utilize efficient systems and training that allow employees to carry out their duties with sustainable practices; this is a critical component of our “Culture of Accountability.” Examples include:
    • Ensuring operational efficiency in systems to eliminate unnecessary labor
    • Beyond what is grown on site, we source local, sustainable, and organically farmed materials whenever available and feasible
    • Employing recycling and composting systems
    • Preserving resources by taking small steps like turning off lights and water when they are not in use
    • Purchase things in bulk
    • Educate employees on household sustainability practices
    • Employing a linen and towel reuse program
    • Using non-toxic cleaning supplies

Community Health and Well-Being:

  • In all of our buildings, we enjoy easy access to nature and create ample natural light and opportunities for biophilic connection.
  • The finishes in parts of the Hospitality House are covered in American Clay, a sustainable substance that replaces traditional painted surfaces. Natural clay plasters help regulate humid air in buildings by absorbing and releasing moisture naturally. The clay brings a healthier comfort to interior spaces and is green, sustainable, and allows for LEED accreditation.
  • Employees who ride-share are rewarded with incentive dollars to recognize their convenience trade-odd. We also provide a daily family meal in the employee lounge along with healthy alternative snacks.
