A glass of wine that you cannot spill and will not go sour for at least nine months - entrepreneur James Nash reckons his invention will revolutionise everything from picnics to air travel.

Mr Nash, the Weybridge-based managing director of Al Fresco Wines, has just launched his plastic glasses - Tulipaks - that come ready-filled with wine.

The wine is sealed in virtually unbreakable glasses with a leak-proof foil lid, and the space in each glass filled with nitrogen that keeps the wine fresh for nine months.

Mr Nash sees the invention as the solution for wine drinkers at outdoor events, picnics, barbecues, and even the worker who fancies a glass of wine with their lunch.

At its launch at an outdoor Rod Stewart concert in Glasgow in July, the company sold 25,000 glasses, the equivalent of one for every person who attended the event.

A pack two glasses in a shop costs £3.99. The single glass on sale at outdoor events costs £3.50. All the plastic can be recycled. The product took two years, and £500,000 to develop.

Now Mr Nash is in talks with US and Australian distributors, as well as representatives from some of the world's biggest wine manufacturers, that seem set to make his invention a global phenomena.

The airline industry is also interested in the concept.

"The response to the product has been incredible," he said. "It really shows we have found a gap in the market.

"In the next year, we would like to stop using subcontractors and open up our own factory."

He also said the product is even winning over the wine buffs.

"Many people were sceptical before but, after realising they were getting fine wine out of a good quality glass, they have really warmed to it."

Wines available in the Tulipak are an Australian Rosé, Shiraz and Chardonnay produced by Trencherman.

They are available from a number of other stores, including Tesco One Stop, and Bookers. For more details, go to alfrescowines.com.
