The lightweight box holds the equivalent of three bottles (2.25 litres), while using the same shelf space as one bottle, and keeps wine fresh for six weeks.
Hardys Nottage Hill will be the first wine to be sold in the new format and will be available in Sainsbury's from 1 November.
Shelf talkers, consumer print advertising, PR, digital media communication and a consumer website, , are accompanying the launch.
Constellation intends FreshCase to take on the current market leader Bag-in-Box in a sector worth £300m in retail sales in the UK.
It is hoped the ergonomic and high-spec design will tackle the challenge of appealing to consumers who do not usually buy wine in large formats.
David Cunningham, Constellation Europe's vice president of business development, said: "We believe it has real consumer and retailer benefits. For the first time, high-potential consumers will be able to buy the premium wine they love in a convenient and very stylish larger format that keeps the wine in perfect condition for up to six weeks after opening.
"As a result, FreshCase will drive incremental sales of premium wine both in the UK and the Nordics"
The design has won support from Research International, which rated the packaging a "Novel Winner" after benchmark testing against 40,000 new product development concepts.
Paul Edwards, chief executive officer, Research International, said: "Only 6% of all new development concepts ever tested by us have achieved 'Novel Winner' status so Constellation's FreshCase is joining a highly select group of successful new products from some of the world's biggest companies.
"Our testing shows that FreshCase appeals to high spending and knowledgeable professional consumers who find the idea exciting, clear and unique."
