Domaine Antonin Guyon Pernand-Vergelesses 1er Cru 'Sous Frétille' is a Premier Cru white Burgundy made by Antonin Guyon. The wine comes from the lesser-known Burgundian village of Pernand-Vergelesses appellation. However, the vineyard is situated on a slope above the Grand Cru vineyard of Corton Charlemagne. The vineyard features limestone and clay soils, which impart a distinct minerality to the wine. The winemaking process involves a protective approach with minimal exposure to oxygen, creating additional reductive, smoky complexity. Overall, Domaine Antonin Guyon Pernand-Vergelesses 1er Cru 'Sous Frétille' is a must-try for wine enthusiasts looking for a more restrained, mineral-driven style of white Burgundy.
