Accredited Auditors

Accredited Auditors 

CSWA has invited experienced auditors with demonstrated knowledge about winegrowing and sustainability management to apply for Certified California Sustainable Winegrowing program (CERTIFIED SUSTAINABLE) accreditation. Accredited auditors must attend an initial training on the certification requirements and also attend annual training programs as part of CSWA's commitment to continuous improvement. CSWA encourages auditors accredited by other third-party certification programs (i.e. CCOF, ISO 14001, ISO 9001, regional wine sustainability programs) to apply for accreditation.

CSWA announces an RFQ for auditors interested in CERTIFIED SUSTAINABLE. Proposals are due November 10, 2017 (deadline extended from November 1). Please view the requirements here: Auditor RFQ
