I am not a big fan of tradition. This is not changing my mind.Havalur is brewed for the annual Thorri festival, in January and February, when locals celebrate ancient gods like Thor and Odinn from Valhalla and eat the food their ancestors did. “We eat rotten (fermented) shark, sour (cured) whale fat, ram´s testicles and so on because that’s what our ancestors ate,” said Ariliusson. The Havalur beer is designed to pair perfectly with the Thorri feast and is popular among Icelanders during that time of year.
