The Canadian Grapevine Certification Network is changing the landscape of grapevine certification. On March 8th, 2021 the Canadian Grapevine Certification Network (CGCN-RCCV) released amendments to its Certification Standards. These amendments include the development of an entirely new set of standards called âCertification Program, Option 2 Protocolsâ and minor changes to the original Certification program that has now been renamed âCertification Program, Option 1 Protocols.â Both of these protocols are available on CGCN-RCCVâs website in English and French.
