You can re-enter an existing brand in your account during registration or create a new one.
If your oil has a different cultivar(s) than last year's, or the organic status has changed, you will need to create a new brand. A new brand's page on the Official Guide will not show awards from previous years.
If your oil is the same as last year, with no changes in its organic status or cultivar contents, always re-enter the same brand instead of creating a new one to maintain and display your brand's winning streak on the Official Guide.
