How long is the shelf life of homemade wine
Generally speaking, the shelf life of homemade wine is only one to two months. Home brewing wine, production standards and health standards are actually not up to standard, the lack of sterilization and other necessary brewing conditions, a lot of wine in the brewing process is easy to deteriorate long mold, so the shelf life is very short.
Homemade wine stored for three years can still drink
Need to be based on the quality of the wine and preservation of the conditions of comprehensive judgment, can not be generalized. If the home-brewed wine is brewed in strict accordance with the scientific brewing process, strict control of sanitary conditions, and is filled, sealed, protected from light, constant temperature preservation, the middle did not open, put three years of home-brewed wine is generally drinkable. If the home-brewed wine is made in a random manner in terms of process, hygiene and preservation conditions, and the winemaker does not understand the brewing principle, brewing process, hygiene management and preservation methods, then the risk of drinking the wine after three years of preservation is relatively high. Because home-brewed wine is relatively light and not durable, it is generally recommended to drink it within 1-2 years. If it has been stored for 3 years, you have to judge it according to the condition of the wine itself. You can taste a little bit less, if the wine has a mellow aroma, no abnormal smell, bright color, fresh fruity aroma, and transparent body with no turbidity, it is generally drinkable. If there are abnormal smells, such as moldy, vinegar, stinky, irritating smells, and turbidity in the wine body, you must not drink it. Wine preservation methods: red wine contains certain pigments, easy to love the impact of ultraviolet light to produce pigmentation and discoloration of the wine. Red wine contains proteins and salts, precipitation easily precipitated at low temperatures cause turbidity; high temperatures are prone to microbial reproduction caused by the deterioration of turbidity, so if the conditions are limited, but also be sure to follow the following principles of storage:?
1, constant temperature. To be stored at a constant temperature of 8-13 ℃.?
2, constant humidity. Red wine is best kept in a space with a humidity of 70% to 80%.
3. Avoid light. Avoid direct sunlight.
4, avoid shock. Shock will disturb the molecular structure of wine and affect her flavor.?
5, no odor. Keep the room odor-free to prevent odors from soaking into the wine.?
6, flat storage. Laying it flat ensures that the corks are constantly moist without drying out and shrinking to let air in.
Homemade wine can be drunk
Making your own wine is fine if you just want to feel the process and have fun?
Please note that when brewing your own wine
1, the fermentation process produces gas, the container mouth should not be sealed, a little cover can be.

3, can not use raw green, rotten and spoiled grapes to make wine, otherwise the wine is acidic and poor taste.
4, grapes need to be crushed and then loaded into the container, which is conducive to the dissolution of beneficial substances.
5, the grapes should not be rinsed too much, the power of fermentation comes from the wild yeast on the skin.
6, the fermentation process can not touch the raw water, in order to prevent infection with stray bacteria, resulting in fermentation failure.
7, the whole process to avoid direct sunlight, the temperature is best within 35 degrees.
