Technical Data & Tasting Notes

The Limited Edition is crafted from 100+ year-old centenary Tempranillo vines, and the Black Series Edition from ancestor vines of over 130 years — blending different clones of Tempranillo, each contributing unique characteristics to the final blend. The flagship All World Edition is a proprietary blend from ungrafted, pre-phylloxera ancestor vines of over 140 years of age. In Napa Valley, Dragonglass planted its favorite clone of Cabernet Sauvignon with the help and advice of legendary viticulturist Michael Topolos.

The Limited Edition ages 24 months in new French oak; the Black Series and All World Editions age 28 months in new French oak before resting in older, larger French oak vats for maximum finesse. All wines complete malolactic fermentation in French oak barrels.

Production is naturally scarce: roughly 2,500 bottles per vintage of the Limited Edition, 533 bottles of the 2017 Black Series Edition, and just 535 and 445 bottles of the 2019 All World Edition and 2020 All World Edition, respectively. Scarcity is a design decision, not a marketing device.

Wines are bottled in 750 ml and 1,500 ml magnums, with rare 3-liter double-magnums and larger special formats released in strictly limited numbers. For collectors seeking something singular, the Dragonglass Unique Barrel Program reserves an entire barrel — roughly 300 bottles of one expression — for a single client or a small group of collectors, upon request.
