The lightest of the Rombeau Rancio secs, the 2010 is distinguished by its cepage and its shorter elevage, with an increased percentage of Macabeu and, atypically, a small amount of Muscat à Petits Grains (roughly 10%) added to the foundational Grenache blanc and Grenache gris. It was vinified in tank with native yeasts, then transferred to an assortment of old barrels and glass demijohns for 12-18 months' aging outdoors. A portion is then returned to the cellars, which rest above ground and lack temperature control, while another portion remained in the "barrel park" until the time of blending and bottling in mid-2016.
