From the label:
The registered trademark “Trappist” certifies that this ale was brewed within the walls of an existing trappist monastery under the control of the trappist community. A major part of the sales revenue is used by the monks to support charitable works. The exceptional yeast isolated by Father Theodore, combined with the purity of the highly protected water of the abbey’s wells, gives Chimay its unique richness. Since 1862, Chimay’s secondary fermented ales have neither been pasteurized nor filtered and only natural ingredients are used. To fully appreciate the pleasant sharpness and the light hint of bitterness of the Chimay Red, serve slightly chilled, in a wide-mouthed glass.
