__NOTOC__
A Koelschip is a critical component to the lambic brewing process. Koelschips serve two purposes. The first is to spread the wort across a wide surface area and allow it to cool. The second is to enable spontaneous fermentation by introducing the desirable wild yeasts and microorganisms of the Le Senne Valley to the wort. Koelschips often reside in the brewery's highest most point and are positioned next to slatted windows or other openings to allow open access to the beer.
Some breweries such as Mort Subite and Belle Vue don't use a koelschip any more. Mort Subite instead uses the [[Brasserie_Mort_Subite#Brewing_Process|Lebeau Method]] and Belle Vue uses the [[Brasserie_Belle_Vue#Brewing_Process|DKZ Method]].
