Gold from nature's pantry: a diachronic study of Rubus chamaemorus L. (Rosaceae) in swedish gastronomy and economy.

backgroundCloudberry, Rubus chamaemorus L. (Rosaceae), is traditionally harvested as food in northern Scandinavia. It is rich in vitamins C, A and E, and antioxidants. This berry has gained much cultural, economic, nutritional, social and symbolic importance in Sweden during the past century. Cloudberries are an important part of culinary heritage. METHODOLOGY: This qualitative diachronic study analyses historical data available in archives and published collections, fragmentary notes in literature and relevant modern data, using a historical ethnobiological approach.

resultsCloudberry is the third most important wild berry species gathered for human consumption in Sweden. The berries were earlier preserved in wooden barrels during the long circumpolar winter; now they are usually frozen or made into jam and other processed products and sold throughout the country. Difficult access to growth areas, weather fluctuations, timing of harvest and lack of gatherers make harvesting challenging. Commercial harvesting has gone from being a sideline income source for the northern peasants to engaging imported seasonal workers mainly from Southeast Asia.

conclusionThis historical overview reveals that local berry picking is decreasing in recent decades. Fluctuations in local weather and lack of foragers influence the availability of cloudberry on the market. In 2025, there were neither enough workers nor berries, and the prices of cloudberry products have risen steeply. The cloudberry, which has enjoyed several decades of popularity both in haute cuisine and among ordinary consumers, will perhaps return to a local wild food gathered only for household needs.
