When Dom Prignon chooses to be ros, it is a radical declaration of freedom. Freedom to explore. Freedom to cast aside conventions and push the boundaries of creation. New Vintage 2008. The Vintage: Overall, the year was hot and dry, but it was marked by contrasts. The initial enthusiasm generated by a heat wave in August was tempered by rain and cool weather in September. In the end, drastic selection in the vineyard guaranteed a limited volume of exceptional quality, with unprecedented aromatic maturity. The harvest began on September 14th.
