Cave de Lugny, Sainchargy, Immémorial Brut Grand Eminent, Crémant de Bourgogne, Burgundy, France NV

You'll find Cave de Lugny's entry-level Crémant at Waitrose, but this superior version (sadly not currently available in the UK) is a world away, with three years of ageing on fine lees as opposed to just the one year for the entry-level wine. A blanc de blancs, so 100% Chardonnay, the wine has an attractive depth of lemon citrus fruit, yellow plum and faint white flowers. Gorgeously elegant. Dosage: 7g/L.
