Why activated carbon is used in spirit filtering
Activated carbon is widely used to filter distilled spirits due to its highly porous structure. These pores trap and bind unwanted compounds, helping improve clarity and smoothness while reducing harshness. Proper use of activated carbon allows for cleaner, more refined results without stripping desired character when applied correctly.
How activated carbon works
Activated carbon works through a process called adsorption, where impurities adhere to the surface of the carbon rather than dissolving into it. This makes it effective at removing certain oils, congeners and trace compounds that can negatively affect aroma, taste and mouthfeel.
Uses in distilled spirit filtering
Activated carbon is commonly used:
After distillation to polish and refine spirits
During slow filtration for improved clarity
As part of gravity or cartridge filtration systems
It can be used in different formats depending on setup and desired level of filtration.
Choosing the right activated carbon
Different activated carbon products vary in granule size, surface area and activation method. Selecting carbon designed specifically for food and drink use ensures safety and suitable filtration performance. Using the correct grade helps balance filtration effectiveness with flavour retention.
Best practices for filtering spirits
To achieve optimal results:
Rinse activated carbon thoroughly before use
Filter slowly to allow proper contact time
Avoid over-filtering, which can remove desirable flavour
Replace or refresh carbon as recommended
Following good practice helps achieve cleaner spirits while maintaining character.
