U grapes help wine industry grow (US)

In the past 30 years, the University of Minnesota has developed climate-enduring wine grapes that are now made into the four most widely produced wines in Minnesota.
A full crop of “cold hardy grapes” can withstand temperatures of up to 33 below zero. Now, a $2.5 million grant from the U.S. Department of Agriculture will allow researchers from the University and scientists from 11 other institutions to research more climate-resistant wine grapes, the acidity and taste within wine grapes and how best to market the wine to consumers.
