Crémant du Jura is an Appellation d'Origine Contrôlée for French sparkling wines. White and rosé sparkling wines can be produced. White wines must be at least 70% Chardonnay, Pinot Noir and Trousseau with the remainder 30% left up to the producer. Rose wines must be at least 50% Pinot Noir, Trousseau or Poulsard. The regions other grape varieties like Savagnin are sometimes blended in as well. Although the AOC only dates to 1995, the production method dates back to the late 1700s.
The AOC standard mandates that the grapes be hand-picked, transported in crates with holes that let the grapes oxidise, and the pressing utilizes grape clusters. More recently many organic and biodynamic producers have made high quality brut nature or brut zero expressions made from Chardonnay.
