The 2020 Andremily Mourvedre from Santa Barbara is a noteworthy example of this varietal, showcasing the distinct characteristics of Mourvedre while integrating Syrah (12%) and Viognier (2%). Originating from the Andremily's new Slide Hill estate vineyard, the Alta Mesa Vineyard and Larner Vineyard in Santa Barbara County, along with the G2 vineyard in Paso Robles, this wine is a product of meticulous craftsmanship.

Jeb Dunnuck awarded this wine an impressive score of 98, describing it as "incredibly powerful, intense" with flavors that include "black raspberries, blueberries, ground pepper, and hints of iron." Dunnuck highlights the wine's “flawlessly balanced” nature and its “ripe, polished tannins” and “nicely integrated acidity.” He recommends either enjoying a bottle soon or allowing it to age for 5-7 years, noting its potential to age well up to 20 years.

Echoing this sentiment, Erin Brooks from Robert Parker's Wine Advocate also scored the wine at 98. Brooks detailed the wine's composition, noting its vinification using 75% whole clusters and maturation over 21 months in 50% new French barriques and 600-liter demi-muids. She observed that the wine reveals "pure tones of star anise, tar, lilac, and chocolate" over time, which complement its "deep core of boysenberry and blueberry fruit." Brooks emphasized the wine’s "highly concentrated, youthfully coiled fruit" and its "very long, layered finish," suggesting it will benefit from additional aging.

Antonio Galloni of Vinous provided a slightly lower score of 94 but still praised the wine as a "super-classic Andremily" with "Blackberry jam, cloves, menthol, licorice, and sweet oak." Galloni noted the wine's "textural intensity" but pointed out that varietal character is somewhat masked by the warmer vintage.

Overall, the 2020 Andremily Mourvedre is a robust and intensively flavored wine, well-received by critics. Its complex profile and aging potential make it a notable choice for enthusiasts of powerful, balanced red wines.
