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 Land

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

Sustainable Tree
Honey Bee Harvest

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.

Wastewater 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.

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.


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.

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.


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.


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.


Within the next few months we will be bringing our Solar plant online and produce a majority of our daily power needs.
