Humle i vått och torrt : En metodstudie av stabila isotoper i recent och arkeologisk humle för att förstå ursprung och användning under svensk förhistoria och historisk tid

Sammanfattning: In this thesis, material of recent hop from different locations in Sweden have been analyzed with EA-IRMS for carbon-, nitrogen- and sulfur isotopes. The aim has been to find a method to distinguish between cultivated and wild hops, and whether it is a useful method for provenancing of hop. Furthermore, hop fruit from archaeological sites have been analyzed with the same method. An experimental water immersion of recent hop fruits has also been carried out, to investigate how this would affect the isotopic values.
