WHAT IS CELITE CYNERGY™?Celite Cynergy™ is a beer stabiliser engineered foroptimised filtration performance.

HOW DOES CELITE CYNERGY™DIFFER FROM CONVENTIONALDE FILTER AID?It is similar to conventional DE in appearance and bulkchemistry. The primary difference is that filtrationperformance is improved due to a 15-35% reduction incake volume. (Typically, xerogel users see a 15-25%reduction while hydrogel users see a 25-35%reduction.) This filter cake reduction is due to theelimination of a separate processing aid (i.e. silica-based beer stabiliser) during filtration.

L REDUCED COST AND COMPLEXITY

CLARITY AND STABILITYTo produce a sparkling and clear beer with a long shelflife often extra steps are required in addition to justturbidity removal by filtration. Consumer habits andproduction trends have placed even greater emphasison shelf life and consistent flavour, clarity, colour andaroma.1. Lowest cost filtration technology available.2. A single DE filtration system can handle a greatvariety of beer types and ingredients and, unlikecrossflow filtration, DE-based systems do not needto be dedicated to only one processing scenario.

3. DE filter aid works well with a variety of beerstabilising agents such as PVPP, silica gel and others.

Chill-proofingChill-proofing refers to extending the “shelf appeal” ofbeer in cold storage. While many techniques forchillproofing are practised, silica gel (either xerogels orhydrogels) are among the most prevalent, either aloneor in combination with other aids (e.g., PVPP). Silica gelworks by removing proteins which cause chill-haze. Inmost cases, the chill-proofing agents are removed withfilter aids. While silica gel does a good job of chill-proofing,adding it as a separate material has disadvantages:

L Requires an additional processing stepL Material is difficult to handleL Reduces the rate of filtrationL Additional storage requirements

CELITE CYNERGY™ DIATOMITE-BASED BEER STABILISING AGENT

Celite Cynergy™ is a diatomite-based beer stabilisingagent that performs better at both filtering and chill-proofing than diatomaceous earth and silica gel addedseparately.

Advantages of Celite Cynergy™ include:L Improved filtration performance- Reduces filter cake volume by 15-35% (dependingon whether you use xerogels or hydrogels) –leading to longer filter runs between filtercleaning- Provides improved filtration performance asmeasured by filtrate clarity, flux and unitconsumption versus using silica gel and DEseparately

L Reduced chill-haze- Selective adsorption of chill-haze proteins(beneficial protein levels remain) yieldinglonger shelf life for beer- No effect on sensory characteristics such asflavour, foam, colour or aroma

L Simplification of the brewing process- Eliminates an extra step in beer clarification – noneed to add silica gel- Reduces storage and management of anadditional raw material

L No additional equipment requirements- Easy to implement in brewery - uses existing DEfiltration processing schemes, equipment andstorage- Compatible with conventional DE delivery andfiltration systems - no need to purchase capitalequipment to store, dispense and use- Easy to optimise process – requires nomodifications to existing equipment

L Cost savings- Cellaring operations are simplified, reducingexpenses- Saves time and materials due to longer filtrationruns between filter cleaning- This proprietary product costs less than DE andsilica gel purchased separately

L Use of same FDA-approved materials- Engineered from materials that already haveGRAS1 status and approval from the FDA2 for usein beer production

THE FILTRATION EXPERTS

IMPROVED FILTRATION PERFORMANCEThe Celite Cynergy™ retains all of the microporous structure of the DE and avoidsthe relatively smooth, spherical surfaces associated with regular silica gels. Theresult is more microporous structure with Celite Cynergy™ than that present in amix of DE and regular silica gel, leading to a higher filtration efficiency.

FILTER CAKE VOLUME REDUCTIONConventional filtration with DE and silica gel creates thicker cakes. With CeliteCynergy™, less total cake volume is required due to the higher filtration efficiency.As a result Celite Cynergy™ will enable 15-30% longer filter cycles, extending theon-line time and so increasing the effective filter capacity and reducing cleaningfrequency & costs.

IMERYS Minerals is the largest producer of mineral filter aids.With over 100 years of experience in the use of diatomite.

Over the last decade, IMERYS Minerals has led arenaissance in beer filtration. Every aspect of the filteraid and beer interface has been investigated – frombeer chemistry to DE particle size, shape and density.This research has given us a depth of understandingand control of composite silica technology which hasmade Celite Cynergy™ possible. We are also theleaders in DE production and quality systems, withover fifty million dollars in investments in our flagshipfilter aids plant in 2008.

Innovations in DE usage and environment-friendlyfiltration remain important to us. One brewery at atime, through filtration audits, we have reduced thevolume of filter aid needed. Every year, our new filteraids are expanding possibilities for breweries aroundthe globe.
