From October to December:
varying by year, late August or early September, the harvest starts in lands reserved for the production of Crémant d'Alsace. Each year, the harvest date is fixed according to maturity by professional bodies after maturity checks done in the vineyard.
Here, we conduct our own inspections of maturity in all of our plots of vines. It is only when we see that maturity of each variety is good that we harvest.
The harvest will extend until October, and sometimes for late harvest until December.
