Bottles of upmarket French wine like Pomerol and St Emilion will soon be on the shelves next to 39 cent grapefruit and blow torches for €10 at Lidl.

In an attempt to woo middle-class shoppers, the discount retailer is launching a new range of premium French wines at its 140 stores in the Republic from September.

Customers will be able to buy Bordeaux classics like St Emilion from €14.99 to €39.99, Pomerols from €19.99 to €34.99 and Graves and Medocs from €14.99.

“The French wines will be an addition to the permanent range of wines from across the world which offer excellent value for money,” a spokeswoman said.

"Lidl Ireland will introduce a range of premium French wines to all 140 stores across the Republic of Ireland from September for a limited period."

Selling more expensive French wines marks a change in the retailer's traditional low-cost strategy and pits it against the likes of Marks & Spencer, Tesco and Supervalu, which recently subsumed the Superquinn brand.

The recent hikes in excise duty on wine - €1 in budget 2013 and 50 cents in budget 2014 -have negatively impacted the sales of discount brands.
