Grand Cru grapes are assigned scores of 100%. As formulated, the score that a grape-lot is assigned within a specific season is an indication of the price that the Champagne House is willing to pay in relation to the pricing for Grand Cru grapes in the season. The Champagne vineyards with Grand Cru designation are shown in the table below.
Within the Valdobbiadene area, the steep hills around the villages of San Pietro di Barbozza, Santo Stefano, and Saccol were considered the Grand Cru of the DOCG. This 106-ha area, called Cartizze, has a mild microclimate and a varied soil to include moraine, sandstone, and clay components. The vineyards are positioned on south-facing slopes and have excellent drainage. Another cru-style called Rive has been added where 43 localities with steep hills in the Conegliano-Valdobbiadene region are allowed to so designate their wines. The requirements for a Rive are : (i) it must be so designated; (ii) production is limited to 14.3 tons/ha; (iii) the grapes must be harvested annually; and (iv) the vintage must be indicated on the label.
