Grape Dehydration Process

The best choice for dehydration is seedless grapes. There are many colors, types, and brands of them. The first thing you want to do is to wash the fruit and remove it from the stems. Pour water into a large bowl and place the grape clusters and thoroughly wash them.

A word of advice – Dehydrating berries and fruits that have a waxy skin will be more efficient if they are checked or blanched in hot water, for about one or two minutes. That way, the moisture can better escape through the cracks that skin will develop after hot water.

After you have done this, drain them and leave to dry for about an hour and a half, making sure there won’t be any moisture. Before you place them on the trays of the dehydrator, it is important to dry them properly. Use a paper towel to roll them over with your hands making sure that you wiped them enough.

If the grapes have seeds, it is best to remove them. Slice them in half to do that, but don’t cut it if they don’t include seeds. When you have done that, place them on the trays of the dehydrator in one layer. Don’t crowd them, because they will not dry properly. Just spread them so the air can reach each one of them equally and dry them adequately. Don’t worry if they touch that is ok.

Set the dehydrator at 135 degrees F and dry fruits for about twenty-four to forty-eight hours. It is important to test them to make sure they are done. When they have a little squish left inside of them, they are ready.


1. Every six to eight hours check the grapes to see the drying speed. You can add more fruits and combine trays because the fruit will shrink in size.

2. As they dry, juices and water will be released from the fruit, which will cause a little outside spot where the sticky, sweet juices are trying to come out. To prevent sticking, shuffle every eight hours. You will notice this more on the red grapes than to green ones.

3. Red raisins will be smaller than the green ones, although they are the same size before drying. Some people prefer green raisins because they have that unique flavor.

4. If you want to speed up the drying process, you can always raise the heat to 145 degrees F for the first twelve hours. To avoid over-drying or burning, reduce the temperature to 135 degrees F.

5. If you want to preserve it for winter, you will need to store it in the airtight jars, vacuum sealer or airtight bag and place it in the pantry. That way they will last for months, and you won’t need to buy dried fruits from the store in those cold winter days. Also, to keep them last for a couple of months it is better to dehydrate them for 48 hours.

6. If you want to check whether they are done or not, just shut off your unit and leave them to cool for about thirty minutes before you taste them. If they are not done, continue drying.
