CASK BEER PRODUCTIONCask Beer, also known as “Real Beer", is a style of beer that originated in England and has been embraced bysome craft brewers. It is an ale that is unpasteurized and completes its maturation and clarification within awooden cask or stainless-steel keg at the retail location where it is to be served. The maturation process includesthe addition of priming sugars and fining compounds. Priming sugars that are fermentable (dextrose/sucrose) areused to adjust the fermentable extract and carbonation levels and non-fermentable sugars (lactose & maltodextrin)are used for sweetness and mouthfeel. Clarification was traditionally accomplished by the addition of “isinglass”a generic term that covers various fish collagens and proteins. Today, many brewers use various forms of colloidalsilicas. Colloidal silicas are vegan friendly and are easier to use than “isinglass”. The wooden cask characteristicwhen producing in stainless steel casks can be mimicked by use of oak alternatives.ClarcollHighly purified fish protein produced with an innovative process to maximize surface chargewithout the need for pre-dissolution in water. Ideal for traditional cask beer production.y Easily soluble.y Effective at low dosages.y Very effective on reducing bitterness and astringency.Application: Add while filling the cask.Dosage Rate: 10–50 ppm. Must be optimized to style being produced.Packaging: 1 kgLiquasil 30 30% silicon dioxide solution designed for the clarification of beer. Increases the efficiencyof protein fining agents while preventing over-fining.y Negative charge combines with positive charge of protein fining agent, creating aflocculating “net” which forces solids to the bottom of the tank.y Should be used in conjunction with a protein fining agent.Application: Add while filling the cask. Dosage Rate: 50–500 ppm. Must be optimized to style being produced.Packaging: 25 kg drumStabisol Silicasol (silicic acid hydrosol) with SiO2 content approximately 30% w/w and a density of1.2 g/mL that crosslinks SiO2 particles to form a hydrogel, which then forms a protein-silicacomplex that progresses to flocculation, and finally forms a very compact sediment resultingin extremely brilliant cask beer.y Charge potential differs from Liquasil 30.y Reinheitsgebot-approved.y Vegan-friendly.Application: Add while filling the cask. Dosage Rate: 50–500 ppm. Must be optimized to style being produced.Packaging: 20 L, 80 L, IBC tote27
