The name Öland comes from the name of an island in the Baltic Sea where this variety is grown.
It was once grown in all Europe and North Africa, but it nearly disappeared from Swedish fields in the ‘60s when more modern wheat varieties were introduced. In 1995, a few devotees re-introduced it. Today a few farmers in Sweden grow it and some bakers make bread with it, encouraging the rediscovery of a breadmaking tradition that has now disappeared. It has also been introduced on a small scale both on the East Coast and West Coast of the United States. Source: https://www.fondazioneslowfood.com/en/ark-of-taste-slow-food/olandsvete-wheat/
