Creating Beautifully Clear & Stable Wine

Producers of wine, both old and new have partnered with Parker Bioscience Filtration for over 30 years to ensure their process and quality needs are achieved.

In Pursuit of the Perfect Wine

The perfect wine should be visually clear, flavorful and maintain its stability over long periods of time. Traditional methods for clarification, such as settling and racking, often don't remove all the particulate and spoilage organisms, producing a cloudy, unstable wine. Clarification and stabilization using microfiltration ensure the removal of particulate and organisms down to 0.45µm, creating a beautifully clear and stable wine without altering the delicate flavor of your wine.

Final Stabilization

Microbial stabilization refers to the process of eliminating yeast and other spoilage organisms from wine. You can effectively cold stabilize your wine using Parker Bioscience's BEVPOR wine filters. These filters use an inert PES membrane that provides validated retention to typical spoilage organisms without impacting the taste or color profiles.
Parker's BEVPOR PH filter cartridges provide validated microbial retention to industry regulated contaminating organisms. Designed as an optimum solution for the microbial stabilization of wine with increased throughput to blockage, high wine flow and maximized operational efficiency.

Fine Wine Polishing & Filter Membrane

Mature or fortified wine is already physically, chemically and microbiologically stable and only requires a final polish to improve clarity and to remove any yeast and bacteria which may be present. Additionally, final membrane filtration is typically the most expensive stage of filtration. Installing pre-filters to remove suspended particles and reduce microbial loading can reduce the costs of replacement final filters.
These microbial reduction filters offer effective control of clarity and microbial stability. They help increase filtration capacity and increase service life when combined with regular CIP regeneration.

Trap Filtration & Crystal Removal

Visible clarity is a sought-after characteristic of good wine. Trap filtration removes suspended particulate to ensure clear wine suitable for intermediate storage. It also reduces costs by lowering the workload of downstream stabilization filters.
By combining absolute particulate retention, high dirt holding capacity and resistance to blockage with ease of regeneration, PEPLYN TF filters from Parker provide the optimum solution for trap filtration.

PEPLYN HD filters have a multi-layer, high depth construction, providing extended service lifetimes and consistent quality filtrate under demanding conditions. These filters capture particulate throughout the depth of the media, with larger particles being captured in the outer prefiltration layers. The inner graded density media provides accurately defined retention to finer particulate.

Product Purge

Product purging involves the displacement of wine from tanks and pipes using compressed gas. Compressed gasses may harbor potentially harmful micro-organisms, which could lead to product contamination. Sterile filtration of the compressed gas ensures all wine purging does not introduce bacteria to the product, maintaining the wines stability. Parker Bioscience can work with you to identify the most appropriate filter selection for your product purge applications.
HIGH FLOW BIO-X sterile gas filters combine proven depth filter technology and a pleated construction to provide retention down to 0.1 micron in gas. They include a stainless steel inner core and are 100% integrity testable by Valairdata 3 aerosol challenge.

Blanketing

To protect the flavor and characteristics of your wine during storage, it is essential to reduce the risks of microbial contamination as well as the capacity for oxidation. To ensure your wine is kept fresh during storage, nitrogen gas is used to purge air out of the tanks so that your wine remains in an inert environment in the vessel.
MAXIGAS nitrogen gas generators produce nitrogen gas from compressed air and offer a cost-effective, reliable and safe alternative to traditional nitrogen gas supplies such as cylinder or liquid. The MAXIGAS provides an on-demand, continuous source of nitrogen gas. It can operate from a standard factory compressed air supply and delivers 5% down to 10 ppm oxygen content, without the need for any additional purification. It is available in 7 models, offering varying flow rates and purities.

Tank Vent Filtration

To ensure your wine does not succumb to microbial contamination, it is essential that all gas entering the storage vessels are sterile. Gas pressure is typically low during most tank vent filtration applications, so the flow performance of the filter and the size of the filter element is important for performance and cost-savings.

Stabilization, Standardization & Tank Removal

In order to protect wine quality during storage or transportation, yeast and other microbial loadings should be reduced. Parker Bioscience developed its PREPOR range of wine filters to excel in tank transfer applications. The PREPOR NG filter is an ideal choice for increased microbial security, fine particle retention and the strength necessary to withstand repeated cleaning and backwash regeneration.
