The category, which does not include Champagne but takes in the likes of Prosecco and Cava, is the fastest-growing in BWS, and leading supplier Freixenet believes it could swell by another £100 million within three years if retailers follow its advice.
Less than one in three shoppers buy into the category and Freixenet urged retailers to increase its penetration by “creating a fizz in store” and making the fixture exciting.
It also said retailers should encourage repeat purchases by linking it to events like “girls night in” and meal deals to push it beyond the typical celebratory events.
The convenience channel is experiencing the strongest growth for sparkling wine, up 31%, and it now accounts for more than a quarter of the market.
Freixenet is also investing in a £1 million marketing campaign to help boost sales.
Champagne sales grew 4% to £328 million during the same period.
