This truly unique Champagne is made without the addition of any sugar (dosage). In the 19th Century, Laurent-Perrier was well known for our “Grand Vin sans Sucre” and is now one of the last Champagne houses to still produce a Champagne of this type. The grapes selected for this wine have a natural acid/sugar balance, so even when fermented to complete dryness no dosage is required. The wine ages on its lees for at least four years and upon disgorging is topped off with wine from the same cuvee. No sugar whatsoever is added to Laurent-Perrier Ultra-Brut at any time.
