A recent blind tasting competition has crowned Co-op's £17 bottles of own-label champagne with the Gold award at the Champagne & Sparkling wine World Championships 2017 - the only supermarket fizz to receive the gong.
And the budget-friendly fizz is in excellent company, ranked alongside prestigious heritage brands including Verve Cliquot, Cristal and Dom Pérignon.
And we're not talking just any old Dom Pérignon... the posh winning wines that appeared alongside Co-op in the winner's list can cost up to 23 times as much as the supermarket's own brand version.
On the left is Co-op's £17 Les Pionniers NV Brut and the right, Les Pionniers 2008 Vintage Brut, £21
Take the Louis Roederer Cristal Brut Rosé 2004 for example, which retails for £396, while the Dom Pérignon 1998 P2 Magnum will set you back £310. Co-op's Les Pionniers NV Brut and Les Pionniers 2008 Vintage Brut on the other hand, cost you a justified £17 and £21, respectively.
Wines from over 29 countries worldwide were entered into the competition, which is deemed to be the most respected, comprehensive and rigorous international sparkling wine competition in the world, judged by a renowned panel of bubbly experts.
Head to Co-Op instead of Harrods for your champagne this year
Ben Cahill, Champagne Buyer at Co-op, comments: "It's fantastic to see Co-op's own brand Champagne rubbing shoulders with some of the most esteemed brands in the industry.
We travel the globe to source top-quality wine at the very best prices and this win just goes to show that buying award-winning wine doesn't have to break the bank."
Sadly, Co-op's award-winning own brand champagnes Les Pionniers NV Brut and Les Pionniers 2008 Vintage Brut aren't available online, but you can pick them up in 2,100 Co-op stores nationwide.
