NOW IS THE TIME
"You can leave the fruit on the vine until the temperature drops to about 28-29 degrees F. At that point they will freeze and be ruined. Check the seeds of the fruit and see if they are now black. If so, that is sufficient for them to ripen. I presume that you do not have a refractometer to check the sugar level - if available, it should read at least 6 to ripen.
When you pick the fruit, leave them off the vine a day or two to be entirely dry. Then put them into plastic bags and seal tightly. Store in the refrigerator for one or two weeks. For ripening, put into a ripening bowl or a plastic bag with an apple or banana. They should give to pressure when ready to eat.
A short time in the refrigerator does seem to help with the ripening. Leaving the fruit out on the counter without the refrigeration phase may result in a dehydrated fruit."
(Eunice: "When I buy Roger's fruit in a box, I put it in the refrigerator. It will keep there indefinitely, so I can buy two or more and they don't spoil.)
