My Niagra grape vine is doing very well this year and has put out
a decent quantity of bunches. The fruit are already 1/4 to 1/2 inch
diameter. A friend told me that I should cut all fruiting vines
immediatey after their last bunch. That I would get larger fruit. Is
there any merit in what I've been told ?

Where are you that you would be harvesting a North American grape
species, Vitis labrusca, in May?

Not harvesting yet. That'll happen end of July to early August. We
live
in the Sandhills of NC. Temps started out high early on but have
cooled off a bit lately bringing much needed rains. Grapes are
thriving.

Question aside, the answer is no.

The vine continues to store starches in its roots, made from
photosynthesis, to be used during the following budding season. If you
want to reduce next year's crop, cutting off the vines while they are
still in photosynthesis is an effective measure.

This vine just barely produces 5 gallons of wine. I need each and
every cluster.

If you want larger fruit, give them more water.

Will do so ...

If you want better quality, drop (cut off) a third of the clusters.


How many buds are you leaving when you prune?

I cut each cane back to two buds.

Thanks for the reply

Paul

Giving the vine more water will give larger fruit and less distinctive
wine. The flavor of the grape is in the skin. The smaller the grape, the
greater the skin to juice ratio, and the more concentrated the flavor. If
you want more juice, water your vine. If you want more varietal flavor,
dry farm it, and consider cluster thinning.

Good enough. I won't bother doing any cutting and will let mother
nature tend to the watering.

Thanks again
