3. Blancs de Blancs Champagne A pure chardonnay-based champagne from Duval-Leroy, showing the rich honeyed aromas of the grape underpinned by toasty, rich flavours and an intensely creamy, biscuity mousse that's textured and appetizingly dry. Irresistible. Where: Sainsbury's, until 3 January How much: £13.99, reduced from £20.99
