Mala Gissona was founded in Oiartzun in 2015 by Iban Zabala and Manu Murillo. Its name comes from the old Icelandic-Basque pidgin expression ''For ju Mala Gissuna'', meaning you´re a bad man, used in the 15th century by whale hunters. They have a taproom in San Sebastián, the Mala Gissona Beer House.
