Piper-Heidsieck, Co-op Les Pionniers Vintage Champagne, France 2013

Made for Co-op by Piper Heidsieck, the Les Pionniers Champagnes (there is also a Non-Vintage) have long been a standout of both the retailer’s range and supermarket own-label Champagnes, and the latest mature Vintage bottling remains a considerable class apart – combining gorgeous, yeasty-patisserie richness with a still-electrifying swish and cut of fine acidity and detailed pointillist mousse.
