The Jean Michel Blanc de Blancs Kosher Brut is a champagne made from 100% Chardonnay grapes. This champagne is fermented and aged in wooden barrels, which can give it a special flavor dimension and texture. The dosage of this champagne is 10g/l, which indicates a light to medium sweetness. This makes it a semi-dry champagne. It is important to note that this champagne has a kosher certification from Badatz chug Hatam Sofer Bnei brak in Israel. This means that it has been prepared according to Jewish dietary laws and may be suitable for consumption during Passover if it is mevushal (pasteurized).
