Use of the combined stabilisation system and its impact on beer composition
The Combined Stabilisation System (CSS) is designed to improve the physical stability of beer through the adsorption of both haze forming proteins and polyphenols by the polysaccharide agarose. In 2005, Lion Nathan commissioned the first large scale CSS unit in the Tooheys Brewery, Sydney. The subsequent trials proved that the CSS has the ability to improve the physical stability of beer within the operational requirements of a large commercial brewery. Physical stabilisation by the CSS appears to occur by the selective adsorption of haze forming polyphenols, in particular prodelphinidin B3, and haze sensitive proteins whilst maintaining foam quality.
