I first found crates full of these white grapes with a scribbled sign stating “local grapes, 1 euro a kilo” at the fruit and vegetable shop down the road. Cheap grapes are a sign that we are already well into the vendemmia (grape harvest) season. Being married to a sommelier I probably should have known right away what kind of grapes they were, after all, this part of Tuscany is the only place that grows these.
