Detailed steps of red wine making

Process: Yeast converts sugar in grape juice into alcohol. The fermentation temperature of red wine is usually 2028 degrees Celsius. The temperature needs to be controlled to ensure the quality of fermentation. Lactic acid fermentation: Process: The bacteria in the wine convert the rough and astringent malic acid into soft lactic acid, reducing the acidity of the wine. Control time is also needed. Clarification and filtration: Purpose: Remove dead yeast and other impurities after fermentation to make the wine clear.

It is best to use static precipitation to remove slag. Alcoholic fermentation: Yeast converts sugar in grape juice into alcohol, and the fermentation temperature of white wine is 8-18 degrees Celsius. The wine is 20-28 degrees Celsius. The temperature needs to be controlled well. Lactic acid fermentation: It is triggered by bacteria in the wine, and converts the coarser and astringent malic acid into soft-tasting lactic acid. This process will reduce the acidity of the wine. Time needs to be controlled.

Raw material treatment: After harvesting, wine grapes need to be picked first to remove mildew fruit grains; then the stems are removed by a machine and gently crushed the grapes (without crushing the grains), retaining 30%-50% of the fruit stems to increase the tannin structure; Then add 50-100mg/L sulfur dioxide to inhibit miscellaneous bacteria. If making rosé wine, part of the grape juice can be separated after crushing and the contact time with the grape skin can be reduced to reduce the color and tannin content of the wine.

How to make wine (red wine)

Put it into a cleaned and disinfected glass jar. Fermentation relies on the natural yeast carried by the grape itself and does not need to add koji.

Transfer to a fermentation barrel and add Saccharomyces cerevisiae (such as EC-1118, 0.2 g/L).

After picking, grapes are first stemmed and crushed (some wineries keep the entire string fermented), and some white wines will be squeezed and peeled first. Alcohol fermentation stage: Yeast converts sugar into alcohol, red wine is fermented with skin to obtain color, and the temperature is controlled at 25-30℃. White wine has a low fermentation temperature (12-22℃), and modern wineries often use temperature-controlled stainless steel cans to maintain fresh fruit aroma.

The brewing process of red wine mainly includes steps such as stem removal, fruit squeezing, juice extraction and fermentation, adding sulfur dioxide treatment, and bottling. Desembering is the first step in red wine making, which means removing the grape fruit grains from the comb-shaped branches. Because the branches and stems contain more tannic acid, this substance will produce an unpleasant taste in the wine and affect the taste of red wine. Therefore, stem removal is an important part of ensuring the quality of red wine.

Cleaning and crushing. The tools for making home-made wine are very simple. The tools used include four medical jars with a capacity of 10 liters, old wine bottles, porcelain jars or small wine jars (clean, not filled with salty food), a plastic or stainless steel rice spoon, a plastic funnel, a plastic siphon tube (5 meters long, can be purchased at markets selling goldfish), a nylon sock for filtering residue, and a wooden stick for mashing and stirring.

Self-brewed wine can be carried out as follows: Tools and raw materials Prepare fermentation containers: stainless steel cans, pickle jars, glass cans or high-quality plastic barrels.

What are the raw materials and auxiliary materials used in making red wine?

The core raw material for brewing red wine is wine grapes, and auxiliary materials are selected and used according to the brewing process and quality needs, covering fermentation additives, clarifying stabilizers, aging flavoring agents and other categories. Wine grapes are the basic raw material of red wine. Unlike daily fresh grapes, they have thicker skins, higher tannins and acidity, and the sugar content is suitable for fermentation needs. Common varieties include Cabernet Sauvignon, Merlot, Pinot Noir, Syrah, etc., the grape juice obtained by crushing and juicing is the core substrate of fermentation.

Anti-oxidant and anti-corrosion excipient Sulfur dioxide is the most common excipient in red wine brewing around the world. It can inhibit the reproduction of miscellaneous bacteria, prevent oxidation of wine liquor, retain the aroma and color, and the compliant usage meets national food safety standards and will not cause harm to health. (3) Clarify and stabilize the auxiliary materials such as gelatin, bentonite (bentonite), chitosan, casein, etc., which are used to absorb suspended impurities and excess tannins in the wine, making the wine body clearer and more transparent, and reducing later precipitation.

The main raw material for making red wine is wine grapes, and the auxiliary materials used are divided into three categories: fermentation additives, clarification and stability additives, and flavor adjustment additives. Winery grapes are the core raw materials for red wine making. Different varieties will be selected according to the target body style, such as classic red grape varieties Cabernet Sauvignon, Merlot, and Pinot Noir. White grape varieties Riesling and Sauvignon Blanc can also be used to make peach or Dry white red wine.

Brewing method of glutinous rice red wine

The brewing method of glutinous rice red wine is as follows: Materials required glutinous rice: 5 kilograms of water: 8 kilograms of red yeast: 1 barrel of brewing steps Soaking glutinous rice: Soak glutinous rice for 4 to 5 hours to fully absorb water and expand.
