Vodka is a beloved and versatile spirit highly regarded for its smoothness. Filtration is a crucial step in vodka production that contributes to its refinement. In this article, we will explore the fascinating world of vodka filtration and understand the scientific principles behind its effectiveness in achieving unparalleled clarity.
Filtration is a process that eliminates impurities and unwanted substances from a liquid. Regarding vodka, filtration is vital in eliminating any remaining particles, impurities, and congeners. This results in a cleaner and smoother spirit.
One commonly used method for vodka filtration involves the use of activated carbon. Activated carbon, derived from sources like coal or coconut shells, has an extensive surface area with countless tiny pores.
These pores act like sponges, capturing impurities as the vodka flows through them. The vodka slowly passes through a series of activated carbon filters, allowing the carbon to absorb impurities such as tannins, fusel oils, and other organic compounds. This process significantly reduces unwanted flavors and aromas that could interfere with the desired clean taste of vodka.
Charcoal filtration is another technique utilized in the production of vodka. Charcoal, typically made from wood or coconut shells, serves as an effective medium for removing impurities due to its porous nature. The vodka is carefully filtered through layers of charcoal, which act as a sieve at a molecular level by selectively capturing undesirable substances.
Membrane filtration is a more advanced method that employs specialized membranes with varying pore sizes to separate particles based on their molecular size. This technique can remove even more minor impurities like microorganisms and dissolved particles. Membrane filtration is often combined with other methods to achieve higher purity levels.
In the case of companies like NEFT Vodka, vodka can also be naturally filtered. NEFT Vodka sources its water directly from a protected water source in the Austrian Alps. The water’s unique location makes it more mineral-rich and naturally filters it through slate and granite. NEFT Vodka then takes this water and combines it with non-GMO rye grains for a simple but satisfying recipe that has won several international awards.
It’s important to note that while filtration plays a significant role in producing high-quality vodka, it should not be considered a substitute for distillation – the primary process responsible for alcohol production. Distillation separates alcohol from other components by applying heat and condensation. On the other hand, filtration is a practical step that complements and enhances the character and quality of the spirit.
