The move has been made in response to demand for the wines in the first 91 stores that stocked them.
The product is the brainchild of entrepreneur James Nash and comprises a plastic glass with a tear-off lid containing a 25cl measure of wine. The idea was rejected on TV’s Dragons’ Den.
“We thought it was a good idea and they’ve been very successful,” said Andrew Bird of M&S.
“If you’d done it in an 8-pack and put it in the dusty, dark, back of the store it wouldn’t have sold so well. We put it in an area of the store with high footfall and it suits the type of customer who is on the go.”?M&S is selling Le Froglet red, white and rosé wines for £2.75.
