The 2021 Covert Estate Clone 337/191 Cabernet Sauvignon is a wine of exceptional clonal precision, outstanding single-estate Coombsville depth, and the kind of intellectually fascinating, terroir-and-clone-specific Cabernet Sauvignon character that the Covert Estate's commitment to viticultural detail and winemaking transparency produces in its most distinctive and revealing form. The Clone 337/191 designation reflects the Covert Estate's deep engagement with the science and art of clonal selection — the recognition that different Cabernet Sauvignon clones, even when grown in identical terroir conditions, produce wines of distinctively different aromatic profiles, tannin structures, and flavor complexities that make single-clone bottlings a uniquely revealing and genuinely fascinating lens through which to understand a great estate's vineyard diversity and winemaking philosophy. Clone 337, prized for its naturally structured, graphite-inflected, and dark-fruited Cabernet Sauvignon character, and Clone 191, valued for its aromatic finesse and red fruit elegance, combine in this wine to produce a Cabernet of outstanding complexity and layered depth. The landmark 2021 vintage gave the Covert Estate Clone 337/191 exceptional growing conditions: aromas of dark cherry, cassis, graphite, cedar, violet, iron mineral, dark chocolate, and a cool-climate freshness lead to a full-bodied, concentrated, and precisely structured palate with excellent natural acidity and a finish of real length and Coombsville distinction.
