This 2019 Blanc de Blancs, likely 100% Chardonnay from a cooler climate region like Adelaide Hills, is expected to offer a bright and crisp aromatic profile. On the nose, look for lively notes of green apple, lemon zest, and white flowers, possibly with subtle hints of brioche or toasted nuts developing from lees aging. The palate should be elegant and refined, with a fine mousse, vibrant acidity, and flavors mirroring the aromas, leading to a long, refreshing finish. It will showcase purity of fruit and a chalky, mineral backbone.
