Dry Creek Vineyard receives patent for wine cork closure

The U.S. Patent and Trademark Office has issued a patent to Dry Creek Vineyard in Healdsburg for its innovative wine cork closure.

The office granted the patent for the closure, which features a laser-printed design that details the source of the cork material. The information includes the harvest date of the trees and the habitat they came from.

The closure was first used with the release of the winery’s 2013 Old Vine Zinfandel. Kim Stare Wallace, the winery’s president, said she developed the idea for the product to provide greater transparency and authenticity for the winery’s portfolio.

“I wanted to provide valuable knowledge to consumers about our sustainability efforts and the benefits of cork closures,” said Stare Wallace in a statement.

Fetzer Vineyards starts new wastewater treatment system

Fetzer Vineyards in Hopland has started using a new wastewater treatment system that relies on billions of worms to clean up the winery’s water.

The worms work together with microbes in the new BioFiltro system, which uses 85 percent less energy to treat the winery’s wastewater. The winery re-uses up to 17 million gallons annually for its vineyards and landscaping.

“From our worms to our winemakers, we have an incredible team that comes together to create innovative ways to make great wine while giving back to the Earth,” said Josh Prigge, Fetzer Vineyards’ director of regenerative development, in a statement.
