"It's not Champagne but it's as good as Champagne." That's the verdict of top chef Michel Roux Jr after travelling to a top English winery in Sussex to taste its Chardonnay bubbly. There, Simon Roberts, winemaker at Ridgeview Winery, took Mr Roux Jr through the vineyard, which backs on to the chalky Sussex Downs, and then into the winery that his parents had built to see how English fizz is made. Unsurprisingly, it's very similar to the method used in the Champagne region of France. But this short film does give a good introduction to English sparkling wine and the high quality chased by winemakers like Simon.
