''. Unlike other cold hardy grapes, it will grow long into fall if weather is clement, but can harden off remarkably fast in a cold snap. This makes it ideally suited for North American winter weather which often include sudden fluctuations in temperature, and is superior in this regard to its rival for second place in cold hardiness among grapes, ''

. ''Vitis acerifolia'' yields strongly colored juice. While berries and clusters are generally small and seedy, it lacks the 'off flavors' of many other North American ''Vitis'' species, having neither the harsh labrusca aftertaste nor the characteristic herbaceous flavor of ''Vitis riparia'', nor the blackcurrant-like flavor common to post oak grapes or the harsh peppery taste of many other native Texas grapes. Low acidity and very early ripening are also important characteristics for potential grape breeders. One varietal that owes its parentage to ''Vitis acerifolia'' is the Canadian variety 'Vincent'. This varietal seems to have more

than other grape cultivars. Since red wines are fermented on the skins and this is the source of 'off' flavors in hybrid wines, it is notoriously difficult to produce cold hardy, quality red wine grape varieties.
