Distilled Spirits Filtration

Spirit Filtration Solutions We Offer at Graver Technologies

Graver Technologies offers a range of distillery filtration products developed to handle the unique needs of spirits production. Each filter type supports a different stage of the process, helping distillers maintain clarity, flavor stability, and consistent performance. Check out the models we offer for filtering distilled spirits.

• CMBF™, PMC™, STC™: These polypropylene filters manage both visible particles and fine sediment during final bottling. They help distillers achieve a clear, bright spirit by capturing solids that might settle later. These filters are designed to meet the stringent standards of USP Class VI, FDA, and NSF 61, ensuring they are safe, reliable, and compliant with industry regulations.

• GFC™: The model 1 um filter is ideal for whiskey chill filtration, removing small charged agglomerates that may cause haze at lower temperatures due to the inherent positive charge of microfiberglass media.  With micron ratings from 0.2 to 30 μm, these filters offer high efficiency, uniform pore size, and high flow rates making it ideal for prefiltra. These chill filtration units to keep your product clear, stable, and ready for bottling, and are ideal for whiskey, vodka, rum, and other spirits.

• WaterTEC™: Made from hydrophilic, asymmetric polyethersulfone membrane and polypropylene components, these filters process water used for dilution and bottle rinsing. This helps prevent contaminants outside particles, taste issues, or odors from entering the spirit through secondary processes. With a 0.2-to-0.65-micron membrane, this filter provides an economical solution without compromising performance, ensuring clean and consistent water quality for your production process.

• QMC™, PMC™: These are designed to remove barrel char after aging and capture carbon fines released during mellowing or polishing. These filters play a vital role in protecting downstream filters and maintaining the consistency of the spirit's character. With micron ratings ranging from 0.1 to 10 μm and 95% filtration efficiency, they provide reliable early cleanup before chill filtration or bottling. When used as a carbon filter for spirits and alcohol, they efficiently capture impurities, ensuring a cleaner, more stable product. Distillers trust these activated carbon alcohol filters to enhance both the taste and appearance of their spirits.

• CelluTEC®: These unique dual layered filters are built with cellulosic media that contains DE (Diatomaceous Earth) and polypropylene media to provide enhanced filtration.  The depth filter cartridges are designed for high loading applications to replace large lenticular filters commonly used to remove  larger volumes of suspended solids as well as components causing chill haze.

Features and Benefits of Our Distilled Spirits Filtration Systems

Our distilled spirits filtration systems are designed to ensure optimal quality and consistency throughout the whiskey filtration process. Here are the key features and benefits of our filtration systems:

• Stable Flavor Profile: Our filters control particle load while minimizing interaction with key aroma compounds, helping the spirit maintain its intended flavor from start to finish.

• Consistent Carbon Trap Performance: Our carbon filter for alcohol effectively captures carbon fines released during mellowing or polishing, preventing unwanted particles from entering later stages of production.

• Reduced Haze Formation: Our chill filtration products remove the agglomerates components that cause haze, helping brown spirits remain clear and visually stable during storage and distribution.

• Improved Bottling Efficiency: Our filters support steady flow rates and reduce clogging, allowing bottling lines to operate longer and with fewer interruptions.

• Versatility Across Spirit Types: Our filtration products work well with whiskey, vodka, rum, gin, tequila, and infused spirits, providing distillers with a flexible solution for multiple products.

• Low Extractables for Clean Flavor: All filter materials meet strict quality standards, ensuring that no unwanted flavors, colors, or odors are introduced into the spirit during filtration.

• Predictable Pore Structure: Our depth and membrane filters provide consistent retention, helping distillers achieve uniform clarity and repeatable results from batch to batch.

• Reliable Performance in High-proof Spirits: Our filters maintain stable performance even at high alcohol concentrations, helping distillers achieve the desired clarity without compromising efficiency.

Application Areas of Our Distilled Spirits Filtration Systems

Our filtration systems are used in a wide range of spirit categories and processing steps, ensuring reliable results regardless of product style or production scale. Some of the key application areas include;

• Whiskey Filtration: Our advanced filtration systems effectively remove barrel char, sediment, and haze-forming materials post-aging, ensuring whiskey maintains its clarity, stability, and rich character without compromising flavor integrity.

• Vodka and Gin Filtration: Our specialized carbon filters trap fines released during mellowing and polishing, preserving the crystal-clear appearance of vodka and gin while ensuring a smooth, clean taste.

• Rum Filtration: Designed to capture suspended solids and manage sugar crystals during production, our rum filtration solutions improve visual clarity and maintain long-term product stability.

• Brandy and Cognac Filtration: Our distilled spirits filtration system removes fine sediment formed during barrel aging, preserving the smooth, rich appearance of brandy and cognac while maintaining flavor.

• Fruit-Infused Spirits Filtration: We provide filtration solutions for fruit-infused spirits that remove colloidal materials and particles from fruits, botanicals, or other additions, maintaining clarity and visual appeal without altering the flavor profile.

• Final Bottling Filtration: Our polishing filters remove any remaining particles before bottling, ensuring that each bottle maintains the desired clarity, quality, and aesthetic appeal.

• Dilution and Process Water Filtration: Our water filtration solutions ensure that dilution and rinsing water remain free of particles and impurities, supporting consistent flavor, quality, and appearance across all bottles.
