Photovoltaic systems, recycled glass, and Babydoll Sheep. These are just some of the eco-friendly tools that vineyards around the world are using to produce bottles of wine.

Cavit Wines is an Italian winemaker that produces 3.6 million cases each year from 13,750 acres in the Trentino region of northern Italy. It’s also one of the biggest U.S. imports of Pinot Grigio and Pinot Noir.

To make all that wine, Cavit uses solar power. In addition, 80% of the glass and aluminum it uses is recycled, and the company has sustainable farming technologies and minimal irrigation systems in place.

According to Marcy Whitman, senior vice president of Palm Bay International, which imports Cavit Wines, the brand takes responsibility — and sees the business need — for taking care of the land and water.

“We are an agricultural business,” she said. “We understand it’s in our long-term interest to safeguard that asset.”

This approach is in keeping with current consumer tastes. According to a consumer survey conducted by the Wine Market Council published on April 13, 48% of the more than 1,100 respondents say how a wine is produced is important to them, even if it isn’t the primary factor in their decision to purchase.

“[W]ine consumers have a tacit interest in consuming wines made in a more ethically responsible manner,” the Wine Market Council report says. The group also consulted with the Wine Business Institute at Sonoma State University for its research.

“Newer consumers are significantly receptive to such production methods,” the report says. “However, a tangible benefit of such wines needs to be communicated in a manner that this market segment both recognizes and values during wine consumption.”

Cavit Wines recognizes the opportunity to reach this younger audience with its production methods.

“Younger consumers are looking for authenticity from the products that they consume and they truly value a company that’s socially responsible,” said Whitman. “That wasn’t the motivation initially, but clearly younger consumers value these things and that positions Cavit in a strong way.”

Nielsen data shows that the rosé business is up 254% for the last five years, and prosecco is up 158% for the period. Cavit Wines released limited edition rosé and prosecco earlier this month with suggested retail prices of $8.99 and $14.99, respectively.

New Zealand’s Yealands Family Wines has come up with a creative – and very cute – way to be more eco-friendly: use sheep to fertilize the land.

Yealands has brought Babydoll Sheep into its vineyard, which provide a natural fertilizer and take care of the weeds, but are too short to reach the grapes, according to Whitman, who also works with the company.

“These are simple natural ways to manage vineyards,” she said.

Yealands also uses recyclable packaging materials, and according to the company’s materials, is the first to be certified carbon neutral, according to the New Zealand CarboNZero programme.

And ZD Wines, a Napa Valley producer that has organically certified estates in Rutherford and Carneros, has incorporated honeybees, owl boxes, chickens and other environmentally conscious elements into their wine production. Renovations currently taking place on the estate will also include sustainable landscaping.

Palm Bay’s Whitman notes that there can be a big upfront investment to take some of these measures, like installing solar panels. But it’s worth it to take care of the soil and water important to these businesses.

“We work with a lot of wineries and these agricultural companies are looking to reduce pesticide use and better stewards of the land,” she said.
