How to Make Raisins

Q. What type of grapes should I grow to make raisins? Is there any special trick to making raisins or do you just dry the grapes?

A. Traditionally, Thompson Seedless is used for raisins but you can use any seedless raisins (usually table grapes). Whichever taste of grapes you like make good raisins. Allow them to dry on the vine (unless birds or ground squirrels are a problem) or remove them from the vine and dry them by themselves.

            Remove the berries from the bunches and remove the stem from the berry.  If there is a secret to drying fruit in the desert, then it is to control the temperature used for drying. I made a solar dryer a few years ago but the air temperature in the dryer was too hot. I ended up using this dryer but put it in the shade rather than in the sun.

            Cover the drying grapes with cheesecloth or any breathable material that helps keep birds and dirt off it. Temperatures should be below 140F, but suggestions will vary. Generally, the lower the temperature and high wind movement the better. So, drying them in the shade in open air in the summer is about perfect here. Just avoid high temperatures (above 140F) and dry them as quickly as possible.
