Regarding the wine point, it is doubtful if wine grapes ever grew in Newfoundland, as the Norse term “Vinland” may well refer to a larger area. From the Wikipedia article:
the southernmost limit of the Norse exploration remains a subject of intense speculation. Samuel Eliot Morison (1971) suggested the southern part of Newfoundland; Erik Wahlgren (1986) Miramichi Bay in New Brunswick; and Icelandic climate specialist Pall Bergthorsson (1997) proposed New York City.[26] The insistence in all the main historical sources that grapes were found in Vinland suggests that the explorers ventured at least to the south side of the St. Lawrence River, as Jacques Cartier did 500 years later, finding both wild vines and nut trees.[27] Three butternuts were a further important find at L’Anse Aux Meadows: another species which grows only as far north as the St. Lawrence
Also, wine grapes certainly do grow in England these days (not just in the Medieval period). There appear to be around 400 vineyards in England currently.
