Napa Green Certified Winery

At our 13th century Tuscan-inspired castle and winery Castello di Amorosa, we are on the cutting edge of Green & Sustainable Practices. Napa Green is one of only four sustainable wine-growing programs nationwide offering the opportunity for comprehensive soil-to-bottle certification in both the vineyard and winery. 40% of all of the certified sustainable wineries in CA are in Napa County. These wineries implement more than 100 sustainability and stewardship standards to
– Save energy and water and increase efficiency
– Prevent waste through recycling, composting, and environmentally preferable purchasing
– Reduce GHG emissions and the winery’s carbon footprint
– Commit to social equity
– The whole facility is certified from production to administration to hospitality
– Commit to social equity

Napa Green Certified

Napa Green Land is a program that recognizes two regional, third-party vineyard certification programs as meeting our standards for watershed stewardship. These programs facilitate environmental compliance and help growers develop custom, whole-property Farm Plans.

- Prevent erosion and sediment runoff
- Reduce and eliminate potentially harmful inputs
- Conserve water resources through efficient irrigation and frost protection
- Protect and restore riparian habitat
- Contribute to a healthy and thriving Napa River watershed

We are committed to working locally to improve the social, economical and environmental well being of our community.

We feel that protecting the environment and doing our part to run sustainable land will lead to great things for future generations.

Sustainable Tree

Fruit Trees

On the Castello property, we planted over 85 fruit trees (including fig, peach, pear, plum and apple tree's). The fruit from these trees is used to make Castello products & for our staff to enjoy during the summer months.



We use the latest in winemaking technology, insuring as little waste as possible. This helps us to both optimize efficiency & also results in a great product. The total electrical energy use must not exceed 7.6 kWh per case of wine produced annually.


Uses low flow nozzles on hoses to conserve water use and shifted use of several fermentation tanks to be used in winter instead of the summer.

Recycled Paper

Currently all the copy paper we order ranges between 30% - 50% recycled paper.

Cellar Practices

The cellar staff steam cleans barrels to reduce waster waste & chemical waste.

LED Lights

LED Lights help us practice the latest in environment efficiency and sustainability. All winery lights have been upgraded to LED lamps saving approximately 2304 kWh/year. The Castle environment also helps us to save light, we use dim lighting which helps us save on energy. The Castello meets all of the Napa Green Certified Standards.

Napa Valley Wastewater Treatment

Wastewaster Treatment

Our wastewater management program goes above and beyond expectation. We use reclaimed water in our vineyards, to keep water waste at minimal levels. We recycle 100% of the water used by cellar staff. Proper SOPs are in place to conserve water. Ensuring all outlets have low flow nozzles or aerators also help us to conserve water.

Waste Program

We consolidate and self haul all plastic wrap from bottling supplies as well as all cardboard to the landfill for recycling. We eliminated the use of Styrofoam when possible. Most green waste is fed to our herd of goats. Overall winery waste is minimal. Downgraded from a 4 yard trash bin to a 96 gallon trash bin. We use copy and printer paper with a minimum of 30% post consumer waste to insure the highest green standards.

Honey Bee Harvest

Save The Bees

With environmental stresses resulting in dwindling bee populations worldwide, they felt it was doubly important for us to do whatever possible to help sustain the local bee population. In the vineyards, the presence of bees attracts beneficial insects which help to keep vineyard pests at bay. Lady bugs and similar insects act as natural pesticides against the destructive insects, eliminating the need for dangerous chemicals. Our bees pollinate the herbs and vegetables as well as our numerous fruit trees—fig, peach, pear, plum and apple—growing in our Castello gardens. In addition, the bees help us to maintain our lush grasses; they pollinate the myriad of wildflowers and berries which grow in abundance in the land surrounding the vineyards, returning rich nutrients to the soil and ultimately, to our vines and grapes.d.

Olive Trees

We are proud to announce the first planting of our Olive Trees surrounding the Castle in Napa Valley. Watch above as President Georg Salzner & vineyard manager David Bejar plant our first olive trees at The Castle! This continues our recent string of sustainability efforts at the Castle.

We planted 12 different varieties of Olive Trees surrounding Castello di Amorosa, these olive trees are known to make a superior olive for oil production. Many of these trees originate in Italy. We look forward to the first fully mature harvest in which we can produce our first olive oil.

castle solar power


We invested $1.4 million in a 450-kilowatt solar power array. The massive 24 panel system was completed in January of 2022 and is situated on a spot which had been a forested slope but was significantly burned in the Glass Fire that hit the Napa Valley in 2020.

“This enormous investment is an important element of our commitment to become as self-sufficient as possible while minimizing our carbon footprint and helping with the climate change crisis. We expect this will offset our energy usage around 80%,” explains Georg Salzner, President, Castello di Amorosa.

Castello di Amorosa partnered with Centrica, Recolte Energy, 127 Energy and DEIF on the multiple components of this installation. 127 Energy designed the 556-kilowatt battery storage microgrid. Using advanced and remotely accessed power controls, the microgrid provides Castello di Amorosa with an independent power supply during frequent utility grid outages. During times of normal operations, the microgrid reduces utility energy charges and demand charges, resulting in significant operational savings for the winery.

“Due to fire risks and skyrocketing power prices, commercial business owners in California are taking matters into their own hands. Castello di Amorosa, Centrica Business Solutions, and Sungrow were great partners on this project and our collaboration exemplifies how innovative teams can solve daunting environmental and energy-related challenges,” said Mark Crowdis, CEO of 127 Energy. “The battery storage microgrid provides a striking juxtaposition of resilient, clean energy technology against the backdrop of historic castle grounds,” Crowdis added.
