Clarity & Stability

Consumer habits and production trends are placing increasing demands on shelf life to preserve flavor, clarity, color, foam and aroma. To produce sparkling, clear beer with a long shelf life requires extra steps beyond filtration. Current standard practice requires a process that utilizes a diatomite filter aid and a silica gel stabilization agent. The Celite Cynergy® beer stabilizing diatomite is the first – and only – solution that provides both while increasing filtration capacity by up to 50%.


Diatomaceous earth (kieselguhr) filter aid is employed in more than 90% of beer production globally for the following reasons:

  • Lowest cost filtration technology available.
  • A single diatomaceous earth filtration system can handle a great variety of beer types and ingredients and, unlike crossflow filtration, diatomite-based systems do not need to be dedicated to only one processing scenario.
  • Diatomite filter aid works well with a variety of beer stabilizing agents such as PVPP, silica gel and others.


Chill-proofing refers to extending the “shelf appeal” of beer in cold storage. While many techniques for chill-proofing are practised, silica gel (either xerogels or hydrogels) are among the most prevalent, either alone or in combination with other aids (e.g., PVPP). Silica gel works by removing proteins which cause chill-haze. In most cases, the chill-proofing agents are removed with filter aids. While silica gel does a good job of chill-proofing, adding it as a separate material has disadvantages:

  • Requires an additional step and dosing unit
  • Material is difficult to handle
  • Reduces the rate of filtration
  • Additional storage requirements

Celite Cynergy® is a beer stabilizing diatomite product that filters like diatomaceous earth (kieselguhr) and cold stabilizes like silica gel, yet performs better than conventional diatomaceous earth and silica gel. When utilizing Celite Cynergy® material volume decreases, resulting in reduced waste, less cleaning and more storage space, thereby...
