Wine grape variety selection is highly localised — particular cultivars are matched to specific climates, soils, and aspect over centuries.
Hardiness ratings
| System | Rating | Temperature range | How to read it |
|---|---|---|---|
| USDA hardiness zone | Zone 5–10 | −28.9 °C to 4.4 °C | Plant tolerates down to this zone |
| RHS hardiness rating | H7 | down to −20 °C | Plant needs at least this level of cold tolerance |
| Canadian plant hardiness zone | Zone 5–9 | −23 °C and warmer | Plant tolerates down to this zone |
| Australian (ANBG) zone | Zone 1–6 | −15 °C to 15 °C | Plant tolerates down to this zone |
Growing notes
- Variety-to-zone matching for wine grapes is highly localised — consult regional viticultural resources rather than relying on generic zone data
- Local wine-region authorities (e.g. Wine Australia, English Wine Producers, regional university extension) publish cultivar-by-region guidance
