The process for making each spirit may vary, depending on the type of spirit and the style of the producer. Whisky production, for example, involves the use of specific grains (such as barley) and aging in specific wooden casks; Vodka, on the other hand, may use a variety of ingredients, such as grains or potatoes, and is usually not agedfor along time. Rum, on the other hand, is usually made from sugar cane and, after fermentation and distillation, may be aged in oak barrels fora deeper color and flavor.
| 01 Preparation of raw materials: According to the type of spirits, choose the corres ponding raw materials, such as grain, fruit, sugar cane, etc.
02 Fermentation: Fermentation of raw materials, yeast convert sugar into alcohol and carbon dioxide. This process is crucial to the flavor formation of spirits.
03 Distillation: The fermented liquid (called “wine mash” or “lees”) is heated to a boil, and the alcohol has a lower boiling point than water, so the alcohol first evaporates and then cools through a condenser to become a liquid, resulting in a high concentration of alcohol. The distillation process can be perform ed one or more times to increase the purity of the alcohol and extract specific flavors. |
04 Aging: Many spirits are aged in oak barrels or other containers after distillation to increase their flavor and color. The length of aging and the type of container can affect the final flavor of the spirit.
05 Blending: To maintain consistency in spirits, winemakers may blend different batches of spirits.
06 Filtration: Before bottling, spirits may be filtered to remove impurities and improve their clarity.
07 Bottling: Finally, the spirits are bottled and labeled, ready for sale. |
SPIRIT FLTTRATION PROCESS
The application of filtration technology in the production of spirits is many, it can not only improve the clarity and stability of the wine body, but also improve the flavor of the wine to a certain extent. In the production of spirits, filtration technology mainly plays a role in the following steps:
● Post-distillation filtration
At the end of the distillation process, spirits usually require filtration to remove impurities that may have been created during the distillation process. Vodka, for example, is filtered after distillation to ensure its pure taste.
● Filtration during the aging process
Some spirits may develop some unwanted cloudy substances during the aging process, and filtration technology may be used to removethese substances and ensure a clear body. In particular, spirits that are aged in oak barrels, such as whiskey and brandy, may be filtered before bottling.
● Pre-bottling filtration
Before the final bottling of spirits, a final filtration step is carried out to ensure that there are no impurities in the final product, providing the best consumer experience. This often involves the use of microporous mem branes or other fine filtration techniques to remove the last tiny particles.
