COMPAC CG (CCG 311)

Compac CG is the semi-refined, granulated form of the seaweed species Eucheuma cottonii.

The species Eucheuma cottonii is rich in the kappa isomer of carrageenan.

When added to boiling wort, kappa carrageenan reacts strongly with soluble proteins, notably the proline-rich haze precursor fraction. When the wort is cooled the carrageenan-protein complex  becomes unstable and precipitates out of solution. The clear wort that results produces a beer with  enhanced processing characteristics.

 

 

 

 

Improved hot break compaction

Improved filtration

Improved yeast vitality

Compac CG is typically added to wort at rates in the range 1–3g/hl. Variations in grist make-up, malt quality, brewing liquor, and plant operation all have a major impact on the carrageenan requirement. The correct addition rate is best
identified by a simple optimization test (see DATA SHEET).
