Dear Dr. Vinny,
Why do you think a supermarket charges £1.80 for a small bunch of grapes when you say 600 to 800 grapes go in a bottle of wine you could buy for £4.00? I know it sounds stupid but I'd love to know.

The two are not interchangeable. That is, wine grapes wouldn't make good table grapes, and table grapes would make some pretty poor wine. Table grapes are grown, processed, shipped, cared for and eventually priced differently than wine grapes, so I don't think it's easy to compare the costs directly. Also, I'm sure that fresh produce (especially at certain times of the year) has more embedded costs than a bottle of wine that has a much longer shelf life.
