"Blancs is a champagne made solely from chardonnay, the only white variety (bar a few esoteric exceptions) allowed in its production. Chardonnay produces fizz of upfront charm, and Ruinart's version is one of the finest on the market, with an instant hit of cream and lemon zest, followed up by toasty complexity and minerality. This is a serious champagne, but with broad appeal - ideal to kick off Christmas Day revelry."
