Although other grape varieties are allowed in Champagne production, they are only planted on 0.3% of the vineyard. There are four of them, all with white grapes. They are Arbane, Petit Meslier, Pinot Blanc and Pinot Gris.
Arbane, also known as Albane, is virtually no longer cultivated due to its late ripening and low yields.
It has citrus and white fruit aromas.
Petit Meslier is an early ripening variety, which exposes it to spring frosts. Not very vigorous or productive, it is tending to disappear.
Rather lively, with citrus aromas and good acidity.
Pinot Blanc is a fairly vigorous grape variety with regular production. Mainly used in Alsace to make Crémant, it is rarely planted in Champagne.
With medium acidity, it is characterized by its yellow fruit aromas.
Pinot Gris, or Tokay in Alsace, is also fairly vigorous but not very productive.
It is well adapted to deep, relatively dry, well-exposed limestone soils.
It brings finesse and aromas. Its low acidity makes it unsuitable for ageing.
