Tesco has seen its own-brand Champagne beat all-comers in a blind tasting. The supermarket's Premier Cru, retailing at GBP14.79 per bottle, beat off offerings from Champagne companies such as Taittinger and Lanson at the International Wine Challenge awards this week.

In the blind taste test, the own-brand Champagne came top out of 282 other non-vintage offerings.

Tesco Premier Cru also won a taste test in Which? Magazine in 2002.
