The right bottles
Wide-neck disposable bottles with screw caps are very practical for canning. Alternatively, weck juice bottles with a large opening, which are closed with a glass lid, rubber ring and metal clip, are suitable.
If you want to continue using used bottles, you should make sure that the seal of the twist-off cap is intact.
Making grape juice
- Wash the grapes carefully, sort out spoiled fruits, remove the stems.
- Put the water in the saucepan 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.
- Use the hand blender to grind the fruit and water into a thick mass.
- Place the cloth over a large colander that you placed over a bowl.
- Let the juice drain and press the grapes good.
- Bring the juice to the boil again and pour in the sugar.
- As soon as the crystals have dissolved, use the funnel(€ 4.58 at Amazon *) fill into the bottles.
- Close immediately.
Reduce the grape juice
For a longer shelf life, it is advisable to also canning the grape juice.
- Place the grapes on the wire rack of the preserving machine.
- Pour in water until the vessels are at least halfway in the liquid.
- Wake up at 90 degrees for 30 minutes.
- Take out, let cool and check that a vacuum has formed in all bottles.
If you do not have a wake-up pot, you can reduce 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 rise in the bottles, switch off and leave the grape juice in the tube for another 30 minutes.
- Take out with a glass lifter and let cool down.
If you store the juice in a cool and dark place, it will keep for at least six months.
Tips
If you have a pressure cooker, you can place the grapes in the sieve insert of the saucepan. Bring to the boil until you hear the steam come out of the valve. Switch off the plate, but leave the pot on it. After cooling, open it and extract the juice as described above.
