We employ many “green” practices here at von Stiehl Winery including nitrogen and ozone generators. Our nitrogen generator was purchased in 2011 and has given us the ability to generate nitrogen that is 99.99% pure, which is utilized in the bottling process to prevent oxidation from happening. By producing the nitrogen onsite, we are reducing our carbon footprint by eliminating the travel expense and carbon impact of heavy steel cylinders to and from suppliers. 

Numerous chemicals can be used in the sanitization process in food production plants, like wineries. One way to avoid using those chemicals is to use our ozone generator. Ozone is infused into water and then sprayed onto any non-porous surface. The ozone will attack and destroy the cell wall of bacteria, immediately eliminating it. To sanitize the entire winery, our ozone is released in a gas form into the air of the production facility at night.
