(TIZWine) - Over half of the UK sparkling wine drinking population say they have tried English sparkling wine, thanks to a better supply and a growing reputation for quality, according to new research published today. Sparkling wine from England, made using the “traditional method”, or the same way as Champagne, has been increasing sales dramatically over the past 5 years as investment has poured into vineyards in the south of England. During the same period sparkling wine sales in general have climbed rapidly in the UK, from around 6 million 9L cases in 2006 to 10 million cases in 2010, defying both the economic downturn and slowing growth in the still wine category.
