Champange is going on sale at woolworths for just £5 a bottle.
The named Worthit! is the cheapest in Britian and will be avaible in 750cl bottles from Monday.
But sales will be limited to just 15 stores where bosses have managed to get a drinks license.
The Woolies fizz, from French producer Henry Villios, is less than half the price of own-label bottles like rivals Asda and Tesco. Woolworths boss Tony Page said. "Champagne is a luxury product but can be produced cheaply, so there is no reason why it can't be sold at value prices.
"This is good champange and at £5, customers won't think twice about buying champange for their celebration, party or event.
The bubbly will be sold in parts of stores away from children's products.
A label on the bottles says it goes best with chocolate rasins from woolies famous "pick 'n' mix" sweet customers
