Oporto 



(Vulpina, Labrusca) 



Oporto was at one time in demand as a wine grape because 

 its wine resembled in color and flavor that from Oporto. The 

 variety is now scarcely known, being inferior in most of its hor- 

 ticultural characters to others of its species, but might be valu- 

 able in breeding for some of its characters. The vine is very 

 hardy, unusually free from fungal diseases, is very resistant to 

 phylloxera and has been used in France as a phylloxera-resist- 

 ant grafting-stock. The juice is very thick and dark, a deep 

 purple, hence suitable for adding color to wine or grape-juice. 

 The origin of Oporto is unknown. It was brought into culti- 

 vation about 18G0 by E. W. Sylvester, Lyons, New York. 



Vine very vigorous, hardy, healthy, variable in productiveness. 

 Canes long, reddish-brown; nodes enlarged, flattened; internodes 

 long, diaphragm thin ; tendrils continuous, bifid. Stamens reflexed. 



Fruit mid-season, ships and keeps well. Clusters small, cylindrical, 

 often single-shouldered. Berries medium in size, round, black, glossy 

 with abundant bloom, persistent, firm; sldn very thin, tender, with 

 much dark wine-colored pigment ; flesh white, sometimes ^^^th purple 

 tinge, juicy, fine-grained, solid, sweet, spicy ; fair quality. Seeds 

 free, numerous, small, broad, faintly notched, sharply pointed, plump, 

 dark brown.
