Home winemakers in the Finger Lakes region might note that Iona juice is being offered for sale by Randall-Standish in Canandaigua this year. I don't recall anyone here offering Iona before. Iona is an old Native American variety having Diana, Catawba and probably some vinifera in its background. It makes into a white wine and often is used in sparklers.
Randall-Standish is referring to Iona as a heritage variety, a nice term for a once popular wine grape that, like many others, fell out of favor over the years. Another grape also qualifying as a heritage variety is Vergennes, a wine now offered for sale by Arbor Hill. Randall-Standish and Arbor Hill are operated by the same group, so this is no coincidence. At a time when native grapes in the Finger Lakes continue to be torn out to make way for vinifera it's heartening to see an effort being made to revive some of the old varieties.
