The term passe-tout-grains means literally 'pass all grapes' – a reference to the lack of berry selection carried out following the harvest. The grains in question are predominantly Gamay and Pinot Noir, although the white varieties Chardonnay, Pinot Blanc and Pinot Gris are also permitted, up to a maximum of 15% of a finished wine. Pinot Noir must comprise at least 30%, with Gamay making up the rest.
