Red wine is an old and sophisticated wine, which is produced through a complex brewing process. Every link from grape extraction to the final brewing is essential. The process of brewing red wines includes a series of steps such as the treatment of grapes, crushing, fermenting and brewing. In this process, the brewer needs to carefully control every link to ensure that the venom is eventually brewed with a layered red wine. We're going to go over the red wine process and the brewing process。
Wine brewing process i. Grape extraction
The first step in making red wine is the extraction of grapes. In general, grapes tend to be harvested in autumn, when grapes mature and contain high sugar. When picking, the day should be chosen without rain, ensuring the quality of grapes。
1. 1 selection of grape varieties
The different varieties of grapes apply to the making of red wines of different tastes. Red grape varieties are commonly used in melo, black pino, sila, etc. Suitable grape varieties are selected for extraction according to the needs and tastes of the wine factory。
1. 2 pick-up methods
Grapes are extracted with caution and ease, avoiding the destruction of the grape skin and influencing subsequent brewing. Picking is best done in the morning or evening, so that grapes are not tanned or damp。
Ii. Squeeze grapes
When grapes are picked, the second step is to squeeze them. The aim of this step is to separate the juice from the fruit peel and the slag from the grapes for subsequent fermentation。
2. 1 grape presses
As a general rule, a wine factory uses a special grape press to squeeze. These machines can efficiently extract the grapes out of clear grape juice while preserving the bark and the slag。
2. 2 separation of fruit skin and juice
After being squeezed, grape juice comes out with fruit peels and slags. It is necessary at this time to use filters to filter out the barks and drosses, leaving only clear grape juice。
Iii. Fermentation process
When grape juice is separated, the fermentation process is required. This is the most important step in the entire brewing process, which directly affects the taste and quality of alcohol。
3. 1 add yeast
Pour grape juice into the fermenting drum and add yeast. The yeast is the key to fermentation, which translates sugar from grape juice into alcohol and carbon dioxide。
3. 2 control of fermentation temperature
During fermentation, there is a need to control the temperature in the fermentation drums, which is usually most appropriate at 15-30°c. High or low temperatures affect fermentation speed and quality。
Iv. China and corrections
The red wine after fermentation needs to be prepared and clarified to increase the taste and sophistication of the wine。
4. 1 brewery process
The red wine, which is fermented, is stored in an oak or stainless steel drum, usually for periods ranging from months to years. In the process, the wine will slowly become more rich and round。
4. 2 clarification processing
In the course of the brewing process, red wines produce some obnoxious substances that require clarification. Clearer liquids by removing impurities from alcohol, including through filtering or adding clarifications。
Red wine production process and brewing process
The process of making red wines requires multiple steps such as picking, crushing, fermenting, brewing, etc. First, fresh grapes are extracted and then squeezed to separate the juice. Grape juice is then poured into the fermentation drums and fermentants such as yeast are added for fermentation. Finally, the fermented fluid is prepared for drinking after a certain period of time。
Ii. Selection of grape types
During the production of red wines, the choice of grapes is important, and different kinds of grapes affect the taste and aroma of red wine. Common varieties of red grapes include chai ju, melo, sila, black pino, etc. Different types of grapes apply to different climatic and soil conditions, and the selection of the appropriate type of grape is key to ensuring the quality of wine。
Iii. Fermentation process
Fermentation is one of the most important elements in the production of red wines, and sugar is converted into alcohol during the fermentation process, releasing rich scents. The timing and temperature of fermentation affect the taste and quality of wine, usually lasting from weeks to months. In the fermentation process, care should be taken to control the temperature and mixing of alcohol fluids and ensure adequate oxygen exposure。
Iv. Oak bullet
After fermentation, the wine enters the oak drum, which can add complex tastes and aroma to the wine. During the broach, the wine slowly reacts chemically with the wood in the oak drums, making the wine more round and full. The impact of different types of oak drums on wine also varies, such as french oak drums and american oak drums。
V. Bottling and storage
After the broach has been finished, red wine needs to be filtrated, purified, etc. Before being bottled. When stored, wine needs to be placed in a constant temperature environment and to avoid light. Good storage conditions allow red wine to be better shaped and develop unique tastes. In general, wines reach optimal drinking levels after 3-10 years of storage。
