History
Golden Mead was an enchanted drink brewed by Lorelei to get Thor to fall hopelessly in love with her.[1]
Lorelei pretended to be a mortal named Melodi and had met Thor in his mortal guise as Sigurd Jarlson but she knew his true identity. She attempted to get him to drink the concoction on multiple occasions with little success.
Ultimately, Lorelei was captured by Malekith and he used an illusion to convince Thor to drink the mead, which he did. After doing so, he realized that the illusion was not Melodi and sought to rescue her but became smitten with her due to the mead's enchantment.[2]
Roger Willis later became suspicious of Lorelei and Thor's unnatural affection for her and ultimately realized the nature of his feelings. He discovered the mead in Lorelei's penthouse apartment and diluted it with water and honey to ensure its effects weren't as pronounced.[3]
