Climate alignment is not a planting recommendation. Variety performance also depends on site, soil, water availability, elevation, aspect, rootstock, clone, management, yield and intended wine style.
Variety matches are maturity-screening results based on the master GDD range. They do not replace local evidence on rainfall, frost, heat, soils, aspect, water, disease pressure, wine style or observed vineyard performance.
