Large quantities of tasty table grapes are ripening in more and more gardens. Often the family cannot eat all the fruit in a short period of time. So what could be more obvious than processing these into delicious juice and preserving the stock for a long time by boiling it down? We explain how to do this in this article.
How can you preserve grape juice by boiling?
To preserve grape juice by preserving it, you need ripe grapes, sugar, lemon juice, bottles and an automatic preserving machine or oven. Boil the washed grapes with water, puree, sieve and warm the juice with sugar. Fill the juice into bottles and cook them for 30 minutes at 90 degrees in the canner or at 180 degrees in the oven.
Ingredients and utensils needed
For two bottles of 1 liter juice you need:
- 2 kg grapes
- 450 ml water
- 75 – 100 g sugar per liter of pressed juice
- 2 splashes of lemon juice
You also need:
- cooking pot
- Hand blender
- Linen cloth or muslin diaper
- Bowl
- Funnel
- Automatic preserving machine or the oven
The right bottles
Wide-mouth disposable bottles with screw caps are very practical for preserving. Alternatively, Weck juice bottles with a large opening that are closed with a glass lid, rubber ring and metal clip are suitable.
If you want to reuse used bottles, you should make sure that the seal of the twist-off cap is undamaged.
Make grape juice
- Wash the grapes carefully, sort out spoiled fruits, remove the stems.
- Put the water into the cooking pot along with the grapes.
- Bring to a boil and simmer for about twenty minutes.
- Meanwhile, sterilize the bottles and lids in boiling water for ten minutes.
- Crush the fruit and water with the hand blender into a thick mass.
- Place the cloth over a large sieve placed over a bowl.
- Let the juice drain and squeeze the grapes well.
- Bring the juice to the boil again and pour in the sugar.
- As soon as the crystals have dissolved, pour into the bottles using the funnel.
- Close immediately.
Conserve grape juice
For a longer shelf life, it is recommended to additionally preserve the grape juice.
- Place the grapes on the grid of the canner.
- Pour water until the containers are at least half submerged in the liquid.
- Soak at 90 degrees for 30 minutes.
- Take out, let cool and check whether a vacuum has formed in all bottles.
If you don't have a cooking pot, you can boil the juice in the oven:
- Place the bottles in a drip pan and add two to three centimeters of water.
- Put in the oven and heat it to 180 degrees.
- As soon as bubbles appear in the bottles, switch off and leave the grape juice in the pipe for another 30 minutes.
- Remove with a glass lifter and allow to cool.
Store the juice in a cool, dark place so it will last for at least six months.
Tip
If you have a pressure cooker, you can place the grapes in the sieve insert of the cooking pot. Bring to the boil until you hear steam coming out of the valve. Turn off the heat, but leave the pot on it. Once cooled, open and juice as described above.
