Particular to the Norwegian tradition is the occurrence of Linie akvavits (such as “Loiten Linie” and “Lysholm Linie”). These have been carried in oak casks onboard ships crossing the equator (“Linie”) twice before it is sold. While many experts claim that this tradition is little more than a gimmick, some argue that the moving seas and frequent temperature changes cause the spirit to extract more flavour from the casks. Norwegian akvavit distillers Arcus has carried out a scientific test where they tried to emulate the rocking of the casks aboard the “Linie” ships while the casks were subjected to the weather elements as they would aboard the same ship. The finished product was according to Arcus far from the taste that a proper “Linie” akvavit should have, thus the tradition of shipping the akvavit casks past the “Linie” and back continues.
