Tasting Notes and Drinking Window:
A lively, well-composed white led by Chardonnay with a hint of Chenin Blanc, this new vintage delivers easygoing charm without sacrificing precision. Fermented and raised entirely in stainless steel, it highlights pure fruit and vibrant acidity. Full malolactic fermentation softens the edges, giving the wine a gentle, rounded finish. Beneath its clean, polished surface lies a thoughtful approach—native yeast fermentation and a no-adjustment philosophy that quietly anchors it in its sense of place.

Vineyards:
Valle de Parras, Coahuila - Planted 2017 in soils of clay and slit at an elevation of 5,000 ft. All estate vineyards are farmed using a regenerative approach, the intention of which is to enrich the biodiversity of the land with every action taken on it. They have a general emphasis on overall sustainability and biodiversity.
Winemaking:
Harvest was carried out by hand in the night to preserve freshness. Grapes were then hand selected and pressed into stainless steel tanks where the juice fermented for 2 weeks before being racked back into stainless steel tanks and left to settle for 4 months so the minimum amount of filtration could be used at bottling. As with all RGMX wines, fermentations were carried out with ambient yeast and wine passed through only a gross filter at bottling.
