The company is bringing out entry-level Diamond Bay Ruby Cabernet and Chenin Colombard, both priced £3.99.
"Our objective was to develop a pair of quality wines that were soft and approachable and that would appeal to a broader spectrum of wine drinkers, which this category does not always achieve at this level," said joint director Antony McIndoe.
"Interest in the Diamond Bay concept and in these two wines in particular has already exceeded all expectations," added fellow director Ray King.
"A significant number of listings have already been achieved, demonstrating our belief that these wines have created a new standard of quality and value."
The range, which is available exclusively to the independent sector, adds to New World wine specialist Discovery Wines' portfolio of new releases.
