Busi-Jacobsohn produces sparkling wines in Sussex, England's established wine region. The winery focuses on traditional méthode champenoise, drawing on Chardonnay and Pinot varieties—the classic grapes of cool-climate sparkling production. The Blanc de Blancs, made entirely from Chardonnay, leads the portfolio with a prestige rating of 93.0 from Decanter. The Blanc de Noirs, built from Pinot Noir and Pinot Meunier, rates at 92.0, while the Brut—a blend of all three varieties—scores 91.5. Sussex's maritime influence and chalky soils support the slow ripening that English sparkling wines require, yielding high acidity and fine mousse. These wines reflect the region's cool-climate character and the technical precision demanded by traditional sparkling winemaking.
