How to brew high-quality liquor 1. The first is the selection of raw materials
The raw materials include grain, water and distiller’s yeast. The grain is required to be free of mildew and moisture. It is best not to use old grain if it is new. Impurities in the grain must be cleaned up. The best water quality is pure water. Only pure water can eliminate the possibility of water bacteria affecting the quality of wine. It is difficult to choose the koji. It is best to cultivate the koji yourself. The only way to choose the koji is through brewing it many times and finally choosing a koji that we think is better. (The quality of koji can only be distinguished in a good and strict fermentation environment.) When making grog, do not use koji that can be used both raw and cooked. Use grog koji instead.
2. Keep fermentation equipment clean and hygienic,
This is rather strict. Regarding cleanliness and hygiene, take a look at this article "Cleanliness and Hygiene Issues That Are Easily Overlooked in Brewing"
3. Fermentation does not require oxygen.
Excessive exposure to the air will lead to more bacteria and oxidants, resulting in more fusel alcohols. Therefore, the entire fermentation process uses semi-sealed fermentation, and liquid fermentation uses shaking and stirring without opening the lid. Do not open the lid during the entire process from fermentation to distillation.
4. Precautions for distillation. If it is a direct heating equipment during distillation, try to choose equipment with a thick bottom to heat evenly. The firepower requires that the heated area should not be too hard. It is best to use boiler-type steam water-insulated heating. Regarding the cooler, try to choose a cooling tower that is relatively high. High boiling point substances will flow back into the pot from equipment with a high tower. Under the same temperature and firepower, the wine tower that comes out of such equipment will be better than a lower one. It would be better if there is a discharge device, and the refluxing high boiling point substances can be discharged directly. The most important thing is to control the temperature. In order to improve efficiency and quality, we control the temperature of wine steaming to about 93 degrees in the early stage so that the wine comes out quickly and the quality of the wine is good. When the wine is lower than 50-40 degrees, it must be lowered. The bottom temperature is controlled at around 90 degrees. The temperature of the wine should not be too low. Too low a temperature of the wine will retain highly volatile substances, and the wine is the first impurity (first wine). According to traditional saying, the temperature of the wine should be 30-35 degrees. Unless the steam is separated before it is cooled, and the highly volatile substances are collected and discharged, they are not allowed to pass through the cooling chamber. The remaining wine steam can be cooled with ice water, so that the output of the wine will be high and the quality of the wine will be better. good.
5. Storage and blending,
The steamed new wine is only good if it is stored for a period of time. The wine must be stored above 50 degrees. For those who like to drink low-alcohol wine, it is best to use mountain spring water when drinking. , if you do not use purified water; do not use tail liquor water and distilled water, these two taste bad.
Home brewing method of liquor raw material formula
Any raw material containing starch and sugar can be used to brew liquor, but the flavors of liquor brewed from different raw materials are different. Grains such as sorghum, corn, and barley; potatoes such as sweet potato and cassava; sugary raw materials such as sugar cane and sugar beet residue, and waste molasses can be used to make wine. In addition, sorghum bran, rice bran, bran, rice washing water, starch residue, sweet potato cranberries, beet heads and tails, etc. can be used as substitute raw materials. Wild plants, such as acorns, Jerusalem artichokes, pear, golden cherry seeds, etc., can also be used as substitute raw materials.
my country's traditional liquor brewing process is a solid-state fermentation method. During fermentation, some auxiliary materials need to be added to adjust the starch concentration, maintain the softness of the fermented grains, and maintain the slurry. Commonly used auxiliary materials include rice husk, rice bran, corn cob, sorghum shell, peanut skin, etc.
In addition to raw materials and auxiliary materials, distiller’s yeast and distiller’s yeast are also required. When producing liquor from starch raw materials, the starch needs to undergo hydrolysis by a variety of amylase enzymes to generate sugar that can be fermented so that it can be utilized by yeast. This process is called saccharification, and the saccharifying agent used is called koji (or koji). , saccharification koji). Qu is a crude enzyme preparation that uses starch-based raw materials as a culture medium to cultivate a variety of molds and accumulate a large amount of amylase. Currently, the commonly used saccharified kojis include Daqu (used for the production of famous and high-quality wine), Xiaoqu (used for the production of Xiaoqu liquor) and Wuqu (used for the production of Fuqu liquor). The most widely used in production is bran koji.
In addition, sugar is converted into substances such as alcohol by the alcohol enzyme secreted by yeast, which is called alcoholic fermentation. The starter used in this process is called distiller's yeast. Sake yeast is a yeast proliferation culture liquid obtained by a relatively pure expanded culture of yeast using sugar-containing substances as a medium. Large vats of distiller’s wine are often used in production.
Have you all learned the methods mentioned above? In addition to the above methods, there are many other ways to make liquor. If you are really interested in learning, you may wish to search for relevant information yourself. The liquor brewed at home is not cheap and you don’t have to worry about quality issues, so why not do it.
Benefits of liquor 1, nutritional supplement
Many alcoholic beverages contain certain nutrients, which can not only supplement the calories needed by the human body, but also supplement the nutrients needed by the human body. Various nutrients necessary for the human body? Protein, fat, sugar, vitamins, inorganic salts and water are basically included in various alcoholic beverages. In addition, the heat generated by alcohol is also one of the benefits of drinking alcohol to human health. Through drinking alcohol, the human body can obtain a large amount of calories, which not only ensures the normal life activities of the human body, but also plays a role in repelling cold.
The role of liquor in cooking is also very unique. When cooking fish, shrimp, and chicken, white wine or rice wine is often used as a condiment, which can make the dishes rich in aroma, reduce trimethylamine in the fish, remove the fishy smell of fish, shrimp, and make the fish, shrimp, meat, and poultry taste more delicious.
2. Promote digestion
The raw materials for brewing wine are mostly grains or fruits, so wine has the nutrients contained in grains and fruits, such as dietary fiber, amino acids, sugars, inorganic salts and multiple vitamins. These nutrients can have a certain stimulating effect on the stomach, promote the secretion of gastric juice, increase appetite, and promote digestion. Therefore, drinking a small amount of low-alcohol wine while eating can not only increase appetite, but also help the digestion of food, which can also play a certain role in promoting nutrient absorption.
3. Protect cardiovascular system
Moderate drinking can also lower cholesterol, expand blood vessels, promote blood circulation, etc., thus achieving the effect of cardiovascular protection.
4. Promote blood circulation and strengthen brain
Drinking liquor scientifically is good for your health. Since liquor contains ethanol, drinking a small amount of it can stimulate appetite, promote the secretion of digestive juices and blood circulation, and invigorate people.
5. Sleep
?
Taking a small amount of liquor at night can gently promote blood circulation and have a hypnotic effect.
