The most important brands of Sparkling wines crown it all right now. It is time to consume their wines, toast with them and make a few splurges as those we cannot afford so often during the rest of the year. Joy and happiness among consumers, but just the opposite among producers. The reason of it: to make public the date of disgorgement.
The reason for this concern is purely economic and logistic: in only one vintage you may need to print 3 or 4 different back labels which would reflect the different disgorgement dates on the bottles.
