Each grape is small

I have grape vines that are 10 years old. THey have been producing long bunches of grapes for years. Even though the bunch is long, with plenty of grapes on each bunch, the individual grapes themselves are so small. These are seedless green grapes. Is this a function of the type of grape or can I do anything to help it produce larger grapes?
I add a little packaged steer manure in the fall and water it in. I have added compost in certain years, sometimes in the spring and sometimes in the fall. When I say small I mean an eighth to a quarter of an inch or so. I would be most grateful for any help. Thanks.

Have you tried thinning the fruit? Reducing the number and size of bunches while the fruit is small should result in plumper grapes.

That sounds like Thompson seedless but could be a similar green grape. Commercially they treat with gibberellic acid during bloom to thin the berries and later to plump up the remainder. They also girdle the vine. Not everyone's cup of tea.

I pinch off the long tips on clusters but that may not make the remaining berries much bigger.

There are now seedless table grapes that naturally have bigger berries. The green grape that matures in August like Thompson with bigger berries is Princess. My favorite, Summer Royal, matures a little earlier and has even bigger berries.
