Grape Variety Libraries
We have planted three grape variety libraries in the Douro, at Quinta do Ataíde, Quinta do Bomfim, and at the Tapadinha vineyard close to Quinta do Retiro. Across these research sites, we have planted 53 grape varieties, comprising many rare indigenous Douro varieties as well as other Portuguese varieties and a few well-known international vines to act as references. We are conducting a multi-year study to understand how different varieties perform under different conditions. As well as safeguarding the Douro’s viticultural heritage, we believe this will be a crucial part of adapting to climate change as growing conditions continue to change.
