What is the minimum annual sunshine hours required to support viticulture?

Explanation:
Sun exposure drives photosynthesis and grape ripening, so a certain amount of annual sunshine is needed for viable viticulture. In practice, about 1,300 hours of sunshine per year is considered the minimum to allow grapes to accumulate sugars and develop proper flavor and phenolic structure. If sunshine falls below this threshold, grapes tend to stay under-ripe, with higher acidity and less balanced flavors. More sun can help further, but the question asks for the minimum, which is around 1,300 hours.
