The individual vineyard lots are fermented separately at cool temperatures in small stainless steel tanks to preserve freshness and fruit intensity. An average of 18 months’ yeast aging adds complexity, contributing subtle bread dough flavors and layers of creaminess. The wine is then disgorged as a Sec style (3.00% RS) and a dosage added back to balance the wine’s acidity. The dosage includes a proprietary blend of late-harvest wines. It rests another three months to fully marry the dosage liquor with the base wine.
