How is wine made?

Wine is one of the oldest drinks in human history. Its brewing process has evolved over thousands of years and formed a rich and diverse technical system. Whether it is wine, beer or liquor, the core principle is to convert sugar into alcohol through fermentation. The following is a detailed introduction to the wine brewing process and key steps.

1. Basic process of wine brewing

The brewing of wine is usually divided into the following steps: raw material processing, saccharification, fermentation, distillation (for some wines), aging and bottling. The following is a comparison of the brewing processes of common wines:

2. Detailed analysis of brewing steps

1. Raw material handling

Different wine types have greatly different requirements for raw materials. For example, beer requires malting and drying barley to make malt, while wine requires selecting grapes of the right ripeness and destemming them. The raw materials for liquor are mostly grains, which need to be crushed and cooked.

2. Saccharification process

Saccharification is a key step in converting starch into fermentable sugars. In beer brewing, the starch in malt is converted into maltose under the action of enzymes; while in liquor, this process is completed by microorganisms in koji.

3. Fermentation process

Fermentation is the core part of winemaking, with yeast converting sugar into alcohol and carbon dioxide. Different wines use different yeast strains and fermentation conditions:

4. Post-processing

After fermentation is completed, beer needs to be filtered and sterilized; wine needs to be clarified and aged; and liquor needs to be distilled and purified. The distillation process has a great impact on the quality of liquor. The traditional process usually uses retort barrel distillation.

3. Popular brewing technology trends

In recent years, winemaking technology has continued to innovate, and here are some emerging trends:

-Low temperature fermentation technology: Better retain wine aroma

-biodynamics：Natural brewing concept in the wine field

-Intelligent monitoring system: Real-time monitoring of fermentation parameters using sensors

4. Precautions for home brewing

For wine lovers, special attention should be paid to:

Wine making is a skill that combines science and art. From raw material selection to fermentation control, every link directly affects the quality of the finished wine. With the advancement of technology, modern winemaking retains the essence of traditional craftsmanship while constantly innovating to bring consumers a richer taste experience.
