Varieties by season timingi

Each dot is a variety: left is earlier, right is later. Gaps of 2 or 3 days are within the method's error.

Varieties measured only at Davis, California (mostly vinifera) can't be compared yet, so they're left out.

BudbreakBuds open in spring. Early budbreak means more risk from late spring frost.

We're just trying to help: this is free, public data from other people's vineyards, and yours will have its own opinions. Please talk to local growers and your nursery before planting 2,000 vines because of a dot on a website; we can't take responsibility for them (or for what the neighbours say).
