On most occasions Extra Brut only has a slight difference and this will be on the taste expression which will be slightly lower on sweetness. The wine is likely to be more ideal for certain food pairings and Extra Bruts are said to be far better on the refreshing and crispness levels.
Extra Brut wines have become much more common in recent decades. As they contain less sugar, Fun fact in a 150 ml glass of Extra Brut Champagne there is 0.5 grams of sugar you would have to drink 28 glasses to consume the same about of sugar in a single Gin and Tonic.
