Activated Carbon for Spirits

Classify: Activated Carbon

Activated carbon has long been applied in the food industry, and activated carbon for liquor is the most widely used. For spirits, activated carbon can not only solve the problem of turbidity, but also reduce the smell in the liquor.

What is activated carbon?

Activated carbon is a carbon material with a well-developed pore structure. It is made from suitable raw materials through processes such as carbonization, activation or rinsing. It is available in food and industrial grades. Activated carbon is a hydrophobic adsorbent with a total specific surface area of 500-1100㎡/g. As an adsorbent, activated carbon is to absorb impurities and odors in the wine, making the wine more fragrant and translucent, and improving the taste quality in the wine production process.

What does activated carbon do to alcohol?

After wine and alcohol are treated with activated carbon, it can promote the esterification reaction between alcohol substances and acid substances, the association between ethanol and water, and the aldehyde substances are partially adsorbed and catalyzed, and the spicy taste in the wine is weakened.
Activated carbon has the effect of increasing the consistency and flavor of wine, which is caused by its aging effect. After activated carbon treatment, the taste of white spirit will be significantly improved. One treatment is equivalent to a natural aging period of about 3 months. It can effectively remove fishy, astringent, bitter, spicy and other flavors in the white spirit, and improve the liquor quality. The aroma and taste make the spirit sweeter and refreshing, enhancing the quality of the spirits. 

What types of activated carbon work best for spirit filtration?

In the process of wine manufacturing and production, various sediments, impurities, odors, etc. will inevitably be produced in the base wine body, causing the original liquor to be turbid and the wine to taste impure and spicy. Activated carbon is widely used in the post-processing of alcohol due to its highly developed pore structure and super adsorption capacity. It can effectively eliminate the foreign smell of the base wine and make the new wine soft, mellow and mature.

1. Coconut granular activated carbon and molecular sieve

These two combinations are mainly used for the purification treatment of spirits. The aging of the purified liquor is accelerated, the smell of new wine disappears, the spicy and foreign flavors are significantly reduced, the body of the liquor is soft and refreshing, and the purified high-quality liquor can be to add slurry at will to reduce the degree of turbidity at low temperatures.

2. Granular activated carbon for liquor

High-quality coconut shell granular activated carbon or fruit shell granular activated carbon is often chosen, in which coconut shell activated carbon is the best. It is mainly used for the deodorization and impurity removal of high, medium and low alcohol liquor and make the new wine soft, mellow and mature.

3. Powder activated carbon for liquor

Powdered activated carbon for wine is refined from high-quality sawdust, fruit shells, coconut shells and other raw materials. It is mainly used to remove turbidity, ripen and age low-alcohol wine.
• Remove foreign odors from alcohol and high-alcohol liquor
• Prevent becoming turbid of low-alcohol spirits with high ester content

How does activated carbon affect spirit taste?

1. Remove the odor of spirits and alcohol and accelerate the aging of liquor

The odor of liquor is from the following sources:
• Improper control of the brewing process
• Improper use of grain substitutes as raw materials
• Liquid fermentation
• Presence in freshly steamed liquor

Usually after long-term storage and aging, some improvement will occur, but some are difficult to overcome. If you add 0.1%-0.2% special activated carbon, stir for 30 minutes, let it sit for 48 hours, and filter the supernatant, there will be no odor.

2. Removal bitterness

Due to careless operations such as fermentation and distillation in the production of liquor, the liquor has a bitter taste. But activated carbon can effectively remove bitterness, the dosage is 0.1%-0.4%.

3. Remove sediment from low-alcohol liquor

In the production of low-alcohol liquor, the solubility of higher fatty acid ethyl esters and higher fatty acid alcohols decreases, resulting in milky turbidity. Customized liquor activated carbon can remove the precipitation of low-alcohol liquor and does not produce turbidity at -20°C.


Activated carbon for spirits is mainly used to improve the purity of liquor, purify impurities and remove odors, so that the taste will be better and purer. Zhulin Carbon can customize activated carbon for different liquor. It adjusts the pore size distribution of activated carbon according to the different liquor quality and processing technology of the winery, selectively adsorbs excess substances, effectively removes flavors and impurities, and purifies the liquor body to perfectly meet customer needs. Contact us today and experience the difference in purity and flavor.
