* Under a Belgian law as amended in 1993, geuze must be made based on spontaneous fermentation only, without specifying what percentage of spontaneous-fermentation beer must be present. Hence, geuze beers and their fruit varieties that are not prefixed with “oude” are not produced by spontaneous fermentation alone, or in some cases only to a very limited extent.<ref name=PalmBoon>Brouwerij Boon Brewery, Brewing Process http://palmbreweries.com/en/boon</ref>
* The beer is stored primarily in large wooden barrels, called foeders. Brouwerij Boon has a park of more than 100 horizontal casks averaging 8,000 litres capacity each. Only old oak barrels are used, as new oak contains too many tannins''<ref name=BoonFoeders>Brouwerij Boon, Best By Dates http://www.boon.be/en/casks-lambic/casks </ref>
