Still, Raoul and Jacques van Custem turned Timmermans into one of the largest lambic breweries in Belgium by supplying lambic to other brewers and blenders who used it for their own versions of geuze and kriek. As Timmermans expanded its footprint in brewing, they also became a distributor of sorts for a short period of time. In looking to expand the brewery even further, the brothers partnered with Rizla, a large cigarette rolling paper company in Belgium. Rizla bought 50% of the company plus one share, and thus Michel Painblanc took over the company. Raoul van Custem slowly withdrew from the brewery.<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 1993, Rizla sold its majority stake in Timmermans to John Martin NV, who still owns the brewery today. John Martin NV, had previously tried to acquire the Eylenbosch brewery and was in the market for a lambic brewery. By 1995, John Martin stopped the production of 75cl bottles and moved everything into 25cl and 33cl cans and bottles. In 2004, Jacques van Custem officially retired, leaving the brewery to be led exclusively by John Martin NV; though he and his son Frédéric still serve in advisory roles.<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=HoralTimmermans>http://www.horal.be/vereniging/timmermans-itterbeek - Timmermans, Dutch</ref>
Though Timmermans has steadily produced a line of sweetened lambic, its canning program is slowly coming to an end. The brewery has recently started to return to its roots by reintroducing an oude gueuze in 2009 followed by an oude kriek in 2010 using sour cherries from Sint-Truiden under master brewer Willem van Herreweghen (previously from [[De_Cam_Geuzestekerij|De Cam]] and Palm Breweries).<ref name=GeuzeKriek>Jef Van den Steen,[[Books#Geuze & Kriek: The Secret of Lambic Beer|Geuze & Kriek: The Secret of Lambic Beer]], 2012</ref> Timmermans is also a member of [[HORAL|HORAL]], guaranteeing that its production methods meet the European Union standards for lambic and gueuze.<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=HoralTimmermans>http://www.horal.be/vereniging/timmermans-itterbeek - Timmermans, Dutch</ref>
