U. P. Hedrick, The Grapes of New York
“ Delaware is the best American table grape and as such commands a premium in all of the markets, selling oftentimes for double the price of Concord. It is also much sought for by wine-makers both for Delaware wine and for blending in making champagne or other wines of high quality. It is grown North and South and westward to the Rocky Mountains, and is now proving especially profitable in many southern locations as an early grape to ship to northern markets. ”
