More than two million bottles of wine bearing a “SIP Certified” Seal are now being distributed, but what is it?

Sustainability in Practice – aka SIP – is a voluntary sustainable agriculture certification standard and the seal on wine labels is intended to verify for consumers that wines were sustainably grown. The program, created by non-profit Central Coast Vineyard Team, launched in 2008, and since then, SIP’s independent auditors have inspected 60 California vineyards representing 15,000 acres of wine grapes, to verify that those vineyards meet the requirements. According to its creators, the seal allows consumers to select wines made from grapes grown by farmers that are mindful of environmental stewardship, equitable treatment of employees, and business sustainability.

SIP’s criteria address environmental and agricultural concerns including habitat conservation, pest management, water conservation, air quality and energy efficiency. The standards also consider benefits available to vineyard workers, including medical insurance, retirement, and safety education. Though many of the now-certified vineyards are found on the central coast, the program is open to vineyards in any location in California.
