Welch's said the agreement represented a significant development and was a first for the company.
The Concord - a grape with large seeds and a "slip skin" which comes off easily - is unsuitable for drying, which means that until now it has not been possible to use the variety in food products.
Mr Tinholt said the New Zealand technical and operations team had done an excellent job developing and commercialising the products for Welch's, while Taura's United States team had done a superb job of building the relationship with Welch's.
Richard Croad, chief operating officer and president of Taura North America, said Welch's grape products were widely known, enjoyed and trusted by millions of consumers globally.
"Now food manufacturers can leverage this brand equity by using URC Concord inclusions in their own products," he said.
"The two companies are a natural fit, combining Welch's brand leadership and high levels of awareness with Taura's expertise in the creation of high-quality concentrated pieces and pastes from real fruit.
"We're excited about the prospects this offers in terms of building entirely new fruit concepts and applications based on the amazing Concord grape."
Wayne D. Lutomski, Welch's vice-president of international and global ingredients, said:
"Through our partnership with Taura Natural Ingredients, and its unique URC process, we will be able to take Concord Grapes into applications never before imagined," he said.
URC Concord pieces and pastes would be available exclusively through both companies, enabling established strong relationships to continue, while at the same time expanding the appeal of the grape further afield, the companies said. The partnership meant Welch's Concord grape would now be available in a wide range of new formats, in combination with other fruits and blended with grains.
"We're excited about the prospects this offers in terms of building entirely new fruit concepts and applications based on the amazing Concord grape."
The first orders are expected to go out next month, said Mr Tinholt.
Initially, the URC Concord pieces and pastes would be available to the North American and North Asian markets, with others set to follow. The Taura sales team was now in Korea and Japan, where feedback was extremely positive.
"Welch's looked at various ways they can add value to their juice concentrate and puree business and found our technology is the only one which can deliver what they require in creating these added value ingredients," Mr Tinholt said.
"We will wait and see what the impact will be on our Tauranga operations, but this is an exciting opportunity for us and we expect volumes to be significant. This breakthrough partnership means we will be using New Zealand-created technology to work with a huge international brand."
US grape juice company Welch's is a co-operative owned by about 1000 growers, with its headquarters in Concord, Massachusetts. The Concord is a purple grape with a distinctive flavour, which only grows in September and October in chilly areas near large bodies of water. It was first cultivated in 1849 in Concord by farmer Ephraim Wales Bull, who wanted to create a grape to withstand the colder climate of the northeast United States.
