The Organic Focus Vineyard Project

Experiences converting to organic management

New organic growers often ask:

  • What are the steps to convert a vineyard to organic production?

  • How do I manage weeds, pests and diseases organically?

  • How do the outcomes of organic production stack up against conventional growing methods?

  • What does it cost to grow organically?


Organic Winegrowers New Zealand created the Organic Focus Vineyard Project to offer some answers. For three years, this project followed three vineyards in different regions as they went through the organic conversion process. The project tracked yields, costs, pest and disease levels, management insights, soil health, grape and wine quality and more. Funding came from the MPI Sustainable Farming Fund and New Zealand Winegrowers.
