Bunch of grapes
Putting grapes through a juicer extracts the sweet flavor and vitamins from the juice, leaving behind the indigestible pulp. Homemade grape juice lacks the preservatives and added sugar found in many commercial varieties. Choose Concord grapes for a traditional flavor or Thompson seedless grapes for a tangy treat.
Pull individual grapes off the stems and transfer these to a colander.

Rinse the grapes in a colander under running water to remove contaminants.
Cut the grapes in half and pull out the seeds if using seeded grapes. Skip this step for juicing seedless varieties.
Feed the grapes into your juicer through the chute of the juicer.
Strain the grape juice again through a fine sieve or colander to separate out any leftover sediment.
Drink the juice immediately to prevent separation.
