Weight Watchers, the international diet programme, has endorsed a new line of diet wines from Australian producer McWilliams Wines.

The most recent collection features four wine variants, including Harmony Sparkling Brut NV, Harmony Semillon/Sauvignon Blanc, Harmony Shiraz and Ezzenze Vine Dancer Marlborough Sauvignon Blanc. All have ABV levels between six and 10 per cent.

A normal glass of red table wine contains 150 calories, according to www.caloriecount.com. A bottle of non-diet wine also contains about 10-14 per cent ABV.

The Weight Watchers wine take pride it only has 6-10 ABV but less calories.

Although it hasn't made available yet the exact calorie content of the wines, McWilliams Wines however assured all of the nutritional information will be clearly labeled on the back of the bottle.

Each bottle will likewise be given a Weight Watchers ProPoint value.

This is not actually the first time that Weight Watchers recommended a McWilliams Wines set. The first that it endorsed for the Australian market was in 2010.

McWilliams Wines is the first winery ever to sign an endorsement deal with Weight Watchers. It targets to bring lower alcohol-content as well as lower-calorie content wines to a new wider audience.

"This is a real departure for wine and it gives us the potential to get in to the mainstream grocery basket. The power of linking up with the Weight Watchers name, which is the 14th biggest grocery brand in the UK, is pretty exciting and a real no brainer," Lloyd Stephens, McWilliams Wins export director, told Wine and spirit trade publication Harpers.

Mr Stephens noted McWilliams Wines hoped to tap the Weight Watchers UK users and get to work with major retailers to pursue customers that already buy Weight Watchers and its diet products.

"Australia and New Zealand are clear growth categories and this partnership is about making dining and entertaining choices wider and easier for those consumers who we know are looking to make healthier choices," Neil Murray, licensing manager at Weight Watchers UK, said.
