Terroir 101 | Heat

The biggest single piece of the score.

Warmth isn't a ladder where more is better. It's a window. Under it the fruit never really ripens — green, hard, and no winemaker rescues that. Over it the sugar runs off ahead of the flavour and the whole thing goes soft.

Every grape's window sits somewhere different. That's most of what people mean when they say a grape belongs somewhere.
