Not all grape varieties are suitable for making natural grape juice. It is important to select species with a high sugar and glucose content: Riesling, Kesha, Cabernet, Isabella, Saperavi Sauvignon and Pukhlyakovsky.

- The juice is squeezed out through a juicer. For this, both an electric and a manual juice press are suitable. It is easy to squeeze the berries out with your own hands.
- The liquid is filtered through cheesecloth. However, such extrusion will take a long time.
Natural grape juice is ready to drink.
For the winter through a juicer
It is permissible to make juice from grapes for the winter from any varieties. If a dark and white variety is used, during the preparation process the berries are sorted into separate containers. In the selection process, the fruits of overripe, unripe and rotten grapes are removed.
For better separation of the juice during pressing, the berries are crushed. The white fruits are immediately passed through a juicer. Harvest of red varieties after grinding for better juice yield is heated to a temperature of 60 ° C-70 ° C. The pulp is diluted with water: 1.5 liters of water are consumed per bucket of crushed grapes. During the heating process, the mass is constantly stirred.
The prepared juice from grape berries is poured into dishes, preferably enameled, and heated to a temperature of 80 ° C. The finished juice, squeezed out through a juicer, is poured into sterile jars and twisted.
The workpiece is stored in a cool place for no more than 2 months at a temperature of about 2 ° C. During this time, the juice can be clarified. You can re-roll the pre-evaporated drink at a temperature of 75 ° C for an hour. As soon as the water cools down to a temperature of 50 ° C, the cans are removed and rolled up. Such production makes it possible to obtain a tasty, healthy drink with a shelf life of about 3-4 months.

To increase the sweetness, the berries are sprinkled with sugar.
The next step is assembling the pressure cooker. Water is poured into the lower container. A juice tank is installed above it. A container with berries is placed at the very top. Before cooking, the hose of the juicer is boiled.
The juice is boiled for an hour
A clamp is put on the hose. The juicer is placed on a lighted burner. The juice is boiled for about 50-60 minutes. Then the clamp is removed from the hose and the one stripped off drink is poured into a pre-prepared enamel dish. The prepared grape juice is poured through a juicer into sterile jars and rolled up.
