Though the strand that connects Brouwerij Boon to the brewing world dates back to the 17th century, the modern history of Brouwerij Boon as a lambic producer starts around 1978 when founder and current owner Frank Boon purchased the De Vits brewery, café, and geuzestekerij when Louis De Vits and his sister Jeanne decided to retire.<ref name=“LambicLand”>Tim Webb, Chris Pollard, Siobhan McGinn, [[Books#LambicLand: A Journey Round the Most Unusual Beers in the World|LambicLand: A Journey Round the Most Unusual Beers in the World]], 2010</ref> <ref name=“GeuzeKriek”>Jef Van den Steen, [[Books#Geuze & Kriek: The Secret of Lambic Beer|Geuze & Kriek: The Secret of Lambic Beer]], 2012</ref> Previously, Frank had been receiving deliveries of De Vits lambic for a local youth club to which he belonged and where he began experimenting with creating faro and blending the various lambics into geuze. After taking over the De Vits name, Boon moved the business from Halle to the Hondzocht district of Lembeek. <ref name=“GeuzeKriek”>Jef Van den Steen, [[Books#Geuze & Kriek: The Secret of Lambic Beer|Geuze & Kriek: The Secret of Lambic Beer]], 2012</ref>
In order to continue blending lambics, Frank Boon also became a beer distributor for local brands. By 1981, Boon purchased a bankrupted factory in the center of Lembeek and moved the distributorship onto the site leaving more room for the blending business at the Hondzocht sitelocation. By 1986, the site in the center of Lembeek was had become home to an automatic bottling plant, a boiling kettle, and a bottle cellar.
In 1988, Frank Boon had purchased a mash tun and kettle from the Rubbens brewery and a second kettle from the Lemaire brewery, thus completing the original Boon brewhouse. Though the new brewing setup initially acted as a pilot brewery for Brouwerij De Gouden Boom (itself owned by Frank Boon and Paul Vanneste since 1983). to avoid excise tax issues, the first batch of Boon lambic was completed in fall 1990.<ref name=“GeuzeKriek”>Jef Van den Steen, [[Books#Geuze & Kriek: The Secret of Lambic Beer|Geuze & Kriek: The Secret of Lambic Beer]], 2012</ref> <ref name=“HoralBoon”>http://www.horal.be/vereniging/boon-lembeek Horal - Boon (Dutch)</ref>
