The weather-not the natives-it got radically colder around 1000 AD-and the site in Greenland wasn’t a settlement in the sense of families farming, etc-it appears to be more of a port for ships to stop and get repairs done/get certain supplies, etc-no evidence of firewater or native interference-just frigid, windy climate...
“The weather-not the natives-it got radically colder around 1000 AD-and the site in Greenland wasn’t a settlement in the sense of families farming”
But they were farming. The famous example is growing grapes. They were able to grow them until the climate turned cold in Grrenland.
Grapes to make wine, I assume. Viking need alcohol! And perhaps Greenland was not suitable for growing enough grain to make enough beer/alcohol etc ______ The grains (rye, barley and wheat) were used to make bread, would be the priority. Rye bread and fish is delicious and a Scandinavian favorite today._______ And maybe was a Viking Greenland staple. Fresh and dried smoked fish.
