In 1964, Grace pioneered the use of silica gel as a beer stabilizer. Just a decade later, we began producing DARACLAR® GR920 hydrogel silica for beer stabilization. We patented the first fast filtering xerogel silica stabilizer and remain an innovator in the development of high-quality beer stabilizers, and more recently, clarifiers. DARACLAR® silica technology is ideal for meeting the demands of today's brewmasters.
With low leachable metals content, this highly pure and consistent protein adsorbent was developed specifically for the brewing process to extend beer shelf life without impacting foam and flavor stability. DARACLAR® silica selectively removes hydrophilic haze-sensitive proteins responsible for chill-haze formation.
