Bairrada DOC

Overview

Bairrada is Portugal’s most misunderstood wine region, producing distinctive wines from the challenging Baga grape that, when well-made, rival the finest expressions of tannic, age-worthy reds anywhere. Located between the Atlantic Ocean and the Serra do Buçaco mountains, the region’s maritime climate and clay-rich soils create conditions that push Baga to its limits—resulting in wines of either harsh astringency or profound complexity depending on viticultural and winemaking expertise. The region also produces Portugal’s finest traditional method sparkling wines. For enologists, Bairrada offers essential study in taming difficult grape varieties, clay terroir expression, and the art of crafting age-worthy wines from challenging material.
