My blueberries are grainy to the taste. They are about 40 years old. They are still good and a lot of them. What should I do to them?

Allow the berries to remain on the bush a little longer. They may not be fully ripened yet. Look for a dark navel when harvesting blueberries, not the color of the fruit. Blueberries with a reddish color around the stem end are not ripe, and will be tart, or grainy. However, those left on the bush to become fully deep blue will be ripe and sweet.
