Larner emphasized the wine's "intensity and purity," noting its "silky and glossy" texture and mid-weight style that "wraps closely over the palate." The wine undergoes fermentation in both steel and oak, with 80% aging in large French oak barrels and 20% in new barrique. She mentioned that the wine was bottled in April 2019 and released to the market in January 2020, with a substantial production of approximately 580,000 bottles.
