Extra Brut [pronunciation: ek-struh broot]
An Extra Brut sparkling wine must contain no more than six grams of sugar per liter. It can sometimes contain none at all, and in these cases many producers prefer to label their wines as Brut Nature, Brut Zéro, or Non-Dosé. On the other hand, wines between 0-6 g./l. of dosage also qualify for the Brut designation, although most producers will label them as Extra Brut rather than Brut.
