Chateau Montelena: Bringing Together Green Technology and Napa Valley History

Chateau Montelena Winery is a stone building nearly 130 years old. But that doesn’t stop winemaker Matt Crafton and members of their leadership team from implementing cutting edge technologies that save energy, water and money while maintaining the integrity of this historic building.

The winery has both Napa Green Land and Winery certifications, but they wanted to further improve efficiency. Matt notes, “Solar is glamorous, but it’s pushing the green ‘easy’ button. Real savings come in the details.” For example, staff noticed when the tasting room is busy, it gets stuffy, requiring more air conditioning. The solution? MacroAir fans with blades shaped like airplane wings. They are low speed, quiet and circulate air efficiently, allowing Chateau Montelena to increase the thermostat 2-4 degrees in summer. “We were the first winery to have this high-tech system. Fans are $3,000 each, but with HVAC savings and customer comfort it was worth it. The fans keep the air dry as well, reducing humidity. It’s a win-win.”

Harvest presented another opportunity for conservation, when the winery simultaneously has high demand for hot water and is generating the most heat. By installing Therma-Stor heat exchangers on their hot glycol system, Chateau Montelena captures waste heat using it to reheat water. Matt says, “Well water is 52 degrees and our waste heat brings it to 110 degrees. Instead of heating water from 50 to 160 or 180 degrees, it only has to go up from 110. This was easy and low cost.”

Other measures range from simple to high-tech. Chateau Montelena found new, decorative LED filament bulbs for their chandeliers, which last for three-plus years, replacing incandescent bulbs that lasted just three months. They were the first winery to install the cutting edge DC Fast station Electric Vehicle (EV) chargers a few years ago. In 2016 they upgraded to Tesla 277 volt stations, providing the fastest Tesla charge available in the valley, along with a universal EV charging station.

The winery is also focused on water efficiency. They worked with Tule Technologies to install vineyard water sensors that measure evapotranspiration and real-time water use, providing immediate feedback on vine stress. Matt notes, “We dry farm the majority of our vines, but if we do water we know exactly how much to irrigate. The sensors are cost-effective – less than $1,000 each. If you save a gallon of water per vine in a 100-acre vineyard, you’re saving 100,000 gallons.

We are always willing to be early ‘green’ adopters. It makes better wine, a better planet and it brings more customers.

I've been at this for 30 years and this is the best, most well-thought-out program I've ever seen.​

One of the main resistances to phasing out glyphosate is increased labor and equipment costs. However, the costs of herbicides and fertilizers have risen dramatically, so increased labor demands can be offset by reduced supply chain purchases. 

In addition, leaders like Grgich Hills Estate have shown that regenerative organic farming can be cost-effective. According to an analysis by Brotemarkle Davis & Co. LLP accounting firm, the average annual per acre cost of vineyard management in the Napa Valley is $14,800, with $3,800 in depreciation. At Grgich, they spend $11,000 per acre, with only $1,300 in depreciation due to the longer life of their vineyards. 

Learn from regional leaders about the practical costs, benefits, and ROI of herbicide-free, organic, and regenerative vineyard management.

Join us for a special roundtable workshop with award-winning journalist Elin McCoy, global wine critic for Bloomberg News and US editor for the podcast The Wine Conversation, with listeners in 95 countries. 

Elin will sit down with a small group of Napa Green members (max 25 guests) and share her insights on the types of stories and pitches most likely to engage the media. In particular, she’ll focus on stories related to sustainable winegrowing, climate action, and social equity. 

Elin will speak and answer questions for about an hour. Then we’ll break into small groups to develop a story pitch, and come back together to present and get Elin’s feedback and input. This is a rare opportunity to get ideas and inspiration from a leading wine journalist. Register at the link in our profile.

One of the most critical agricultural concerns with our changing climate, and more frequent & intense weather extremes, is precipitation and water availability. The good news is opportunities abound to optimize irrigation efficiency, and implement regenerative practices that improve soil health, water infiltration, and retention. 

Join us for The Future of Water, with highlights including a keynote from Peter Gleick, one of the world’s leading water experts, and Mimi Casteel, not only a viticulturist and winemaker, but also a forest ecologist with a vision for water resiliency.

Join us for The Future of Water Workshop, to explore our water future, with highlights including a keynote from Peter Gleick, one of the world’s leading water experts (all guests will receive a copy of Peter’s most recent book, The Three Ages of Water) and Mimi Casteel, not only a viticulturist and winemaker, but also a forest ecologist with a vision for water resiliency.

Wine grape quality is closely tied to the right amount of water, at the right time. One of the most critical agricultural concerns with our changing climate, and more frequent & intense weather extremes, is precipitation and water availability. We’ve swung from historic drought to atmospheric rivers. Our community has huge swaths of unmanaged, unhealthy forests full of non-natives and overrun by firs, amplifying fire risk and undermining one of the most critical systems for groundwater recharge.

The good news is opportunities abound to optimize irrigation efficiency, and implement regenerative practices that improve soil health, water infiltration, and retention. A watershed coalition has also formed in Napa County to pilot and model creek & forest restoration for localized water resiliency and climate cooling. 

Come learn more on Thursday, May 23rd at 9:00am at @silveroakcellars.
