Drying grapes on the vine

Question 1

What happens when you dry grapes on the vine?

Answer 1

Grapes shrivel. Water lost by transpiration.
Aromas develop- eg dried apricot.
Dry autumns needed to avoid grey rot.
Can also cut cane off vine before harvest= grapes shrivel more quickly.
Obtain high levels of sugar, no extra ripe flavours.
