Certification is extremely important because it protects consumers from fraud. 

Organic farming today is based on long-standing traditional farming methods. However, many producers who claim to follow traditional farming methods, and limit or exclude the use of synthetic chemicals such as pesticides, fungicides, etc, are not formally registered with any certification agency verifying and overseeing that the organic regulations are being followed. 

Although growers may claim their produce is organic without certification, certification is the consumer's greatest assurance that the grapes used in the wine were produced in accordance with legally established organic standards, and that the grower has been required to document and demonstrate the organic claim.
