Decanter gave this wine a score of 93, noting its "very darkly coloured for the vintage" appearance. They described it as "broad and full-bodied but not over extracted," with tannins that are "quite burly, but should settle in time." The wine features flavors of "plums, blackberries and liquorice." Decanter highlighted its powerful profile, even if it lacks great depth. The wine was fermented in stainless steel and concrete, then aged in concrete and old oak. The lieux-dits mentioned include Barbe d'Asne, Bois Lauzon, La Crau, Crista, Le Pointu, and Les Roumiguières.

Jeb Dunnuck also rated the wine 93 points, describing it as "slightly deeper ruby/plum-hued" and highlighting its complex aroma profile which includes "smoked red and black fruits, ground pepper, cured meats, and leather." Dunnuck praised its "ripe, savory, already complex" nature and mentioned that it is "medium to full-bodied" with a "round, seamless mouthfeel, ripe tannins, and a great finish." He suggested that while the wine is already showing nicely, it has enough tannins to benefit from a few more years of aging.

Robert Parker's Wine Advocate awarded the wine a score of 91. Joe Czerwinski noted that the wine continues Sixtine's tradition of reliability, offering "attractive aromas of menthol, black cherries and garrigue." He described it as "medium to full-bodied, moderately concentrated and gently tannic on the lingering finish."

Overall, the 2020 Chateau Sixtine Chateauneuf du Pape is a well-received wine, praised for its complexity, broad body, and aromatic profile. Each reviewer noted different aspects of its character, but all agreed on its quality and potential for further aging.
