How this map works
Every 28 km square of land is scored 0–100 against the requirements above, using 1991–2020 monthly climate averages with frost, chill and heat estimated by simulating daily weather. This map is for Wine grapes (Cool-climate) only. “Irrigated” ignores rain shortfalls; “Rainfed” counts them. Tap any square to see everything that grows there.
Climate is only part of it: soil, slope, water and markets decide where a crop is actually farmed. Use this to shortlist places, then check them locally.
