To construct the 2019 Liv-ex Classification, the following methodology was applied. In order to qualify for the ranking, a wine must have traded on Liv-ex between 30 April 2018 and 1 May 2019 in either a 75cl or 150cl bottle format. Standard in Bond, Standard En Primeur and Duty Paid trades were all considered, except for Burgundy, Champagne, Australia and the USA, where Special trades were also permitted.
