Brut Champagne is a dry sparkling wine from the Champagne region of France, made fizzy by a second fermentation in the bottle.
Fine, steady bubbles carry a crisp, high-acid, dry wine, with a toasty, bready note from its time on the lees.
Bartenders add it at the last moment, to top a drink with bubbles and dry acidity — it finishes a French 75, a Mimosa or a Kir Royale. Pour the other ingredients first, then the Champagne, so it doesn't foam over, and never shake it, or the fizz is lost.
Any dry sparkling wine covers the job — cava or a brut prosecco keep the bubbles and the low sugar, though tank-made ones miss Champagne's toasty depth. Keep the substitute dry and sparkling, and fix any sweetness gap with a touch of syrup.
Champagne is made in France by the traditional bottle-fermentation method, while Prosecco is Italian and made by the tank (Charmat) method; confusingly, Prosecco's 'extra dry' is actually sweeter than 'brut', so the sweetness labels do not line up.
Sparkling wine (generic)
Only wine from the Champagne PDO region made to appellation rules may be called Champagne; other sparkling wines, even those made by the same traditional method elsewhere, may not use the name.
It comes only from the Champagne appellation in north-east France, made mainly from Chardonnay, Pinot Noir and Pinot Meunier by the traditional method — a base wine ferments a second time in the sealed bottle, trapping the bubbles. "Brut" means dry: under 12 g of sugar per litre. It's drier than sec or demi-sec, but a touch sweeter than extra brut and brut nature.
Once opened it goes flat quickly, so use it soon after popping the cork.
Champagne comes only from the Champagne region of France, where the traditional bottle-fermentation method grew up and where the name is legally protected.
