Longan wine is a wine made from longan. It is necessary to know that the longan fruit has a lot of juice, high sugar content and good flavor. It is a high-quality raw material for brewing fruit wine, which can produce high-quality longan wine with fragrant smell, elegant flavor and pleasant color. After the qi and nourishing effect, improve blood circulation, eliminate fatigue, protect blood vessels and other effects. Therefore, today Xiaobian talks about longan wine brewing technology.
First, the longan wine brewing process
Longan→cleaning→peeling and nucleating→beating→filtering→adjusting acidity→pasteurization→cooling→inoculation→main fermentation→post-fermentation→separation of wine feet→aging→bottling, as follows:
1. Selection and pretreatment of raw materials
The freshly ripe longan fruit is selected, and the fruit is washed twice with tap water, peeled and nucleated, the pulp is slurried, and then filtered, and it can be immersed in a 60-degree wine as a sparkling wine.
2, adjust the acidity and alkalinity
The longan juice itself has a total sugar content of 20%, and the self-fermentation produces an alcohol content of 10% (v/v). In order to increase the alcohol content, the total sugar of the fermented mash can be increased to 25% and 28%, respectively.
3, pasteurization
It is pasteurized at 70 degrees, which can kill the bacteria and make the fermentation liquid easy to clarify without affecting the inherent flavor of the longan.
4, vaccination
The amount of yeast used was 0.2%. The wine high-activity dry yeast was first activated with 5% sucrose solution and 10% juice at 37 to 40 degrees for 60 minutes, then poured into the fermentation mash and stirred evenly.
5, the main fermentation
The above fermentation mash was poured into a fermenter and sealed, and the temperature was controlled at 20 ° C for main fermentation.
6, post-fermentation
After the main leaven is finished, the wine feet are separated and the cans are transferred to the post-fermentation.
7, alcohol adjustment
Add 60 degrees of rice wine to adjust to about 20 degrees.
8, aged
It is sealed at room temperature.
9, bottling
After clarification by aging, bottling.
Second, the matters needing attention
1. The temperature of the main fermentation is closely related to the fermentation speed and the quality of the finished wine. However, the higher the temperature, the faster the fermentation speed and the rancidity. Therefore, it is more suitable to control the temperature at 20 °C.
2, adding 60 degrees of rice wine can increase the degree of alcohol, the disadvantage is that there is a rice wine flavor, which dilutes the original flavor of longan wine, it takes a long time to hide to taste the rice wine.
