Exton Park Vineyard produces sparkling wines from England's cool climate, where Chardonnay thrives in chalky soils and conditions mirror those of northern France. The winery's RB|45 Reserve Blend Blanc de Blancs—a pure Chardonnay expression—achieves depth and complexity through extended aging, earning recognition from Decanter and Wine Advocate. The Blanc de Blancs offers a more accessible entry point to the same varietal, while the Rosé, built from Pinot Noir and Pinot Meunier, brings structure and elegance. English sparkling wine has emerged as a serious category over the past two decades, and Exton Park's releases demonstrate the region's capacity for precision and finesse in the bottle-fermented tradition.
