Through the late 1800s, people assumed that the right combination of wild yeasts for lambic only existed in the Pajottenland. Technically, in 1904, Danish brewing scientist Niels Kjelte Claussen discovered the first brettanomyces in an English beer. He presented his findings to the British Beer & Pub Association and later published them in the Journal of the Institute of Brewing. Because he found these yeasts in British beers, he chose the name “brittanomyces” (the Greek word for “British fungus”). However, a typesetter’s error changed this to “brettanomyces,” with an ''e''.<ref name=GeuzeKriek>Jef Van den Steen, [[Books#Geuze & Kriek: The Secret of lambic Beer|Geuze & Kriek: The Secret of Lambic Beer]], 2012</ref> | Through the late 1800s, people assumed that the right combination of wild yeasts for lambic only existed in the Pajottenland.

In spite of brettanomyces existing worldwide, it is still reasonable to assume that the combination and ratio of brettanomyces and other individual microorganisms within the Pajottenland are unique to the local terroir. For example, in 1993, Frank Boon was said to have discovered 86 unique strains that he believed played a significant role in the fermentation at [[Brouwerij_Boon|Boon]].<ref name=Lambic.digest-9312>Lambic Digest, December 2, 1993, | In spite of brettanomyces existing worldwide, it is still reasonable to assume that the combination and ratio of brettanomyces and other individual microorganisms within the Pajottenland are unique to the local terroir.

However, the naturally occurring yeasts at Boon are significantly different than yeasts occurring at Cantillon, for example. Even the yeasts at an individual location will change over time. Cantillon is now surrounded by buildings, cars, and industry. As cityscapes change so does the local terroir. The yeasts of 50 years ago at any location are likely different than the yeasts of today. Even the yeasts and other microflora at other locations around the world have similar characteristics. Studies have shown that yeasts in other regions, such as the Allagash Brewery in Maine, have a similar makeup.<ref name=AWAStudy> Brewhouse-Resident Microbiota Are Responsible for Multi-Stage Fermentation of American Coolship Ale, http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0035507</ref> | However, the naturally occurring yeasts at Boon are significantly different than yeasts occurring at Cantillon, for example.
