Climate decides how ripe the grapes get. Ripeness decides almost everything you taste.
Wine regions are graded from cool to warm by growing season temperature. Choose a lens and watch the three respond.
Two regions at the same latitude can differ widely. A handful of factors nudge any vineyard off its baseline.
Climate type is a separate idea from warmth: it is the rainfall pattern and how much the temperature swings across the year. A region has both. Bordeaux is moderate and maritime; Barossa is warm and Mediterranean. Choose one to see its signature.
Note. Climate is the long-term average; a single year is its weather, which is why vintages differ. At the warm extreme, hot climates can give cooked or dried-fruit flavors and very low acidity, and often need irrigation. Growers and winemakers can also adjust, for example by picking earlier or adding acidity in warm regions. These are tendencies, not rules: site, grape variety, and winemaking all shape the final glass.
