I was wondering if there was anything that i could do to improve the size of the crop. Not sure what type of grape vine it is as like i mentioned it is quite a mature grape vine, and i don't think the previous owners have really looked after it or really prunned it. I was thinking of pruning it this year maybe that would help, but have no idea how far back i should prune this vine back to.
Hope someone can help!

If each bunch has lots of tiny fruit, I suspect someone has overlooked the need to thin the fruit. Use thin pointy scissors, snip off alternate fruitlets. The aim is to have fewer fruit to the bunch - not fewer bunches. This allows more room and nutrients for those left to grow
bigger. Vines also benefit from a mulch, and need water to swell the fruit.
I'm far from being an expert, and perhaps someone else can explain better, but most gardening books show how it should be done.
Watch out for mould, it can ruin the lot in very short time.
