Unseeded for convenience, but if the seeded ones are nicer/better tasting, I will buy those as well. Love grapes. We call them "lollies gifted by nature".
Seriously.
Who would want to eat seeded, when you get one and bite down hard, and your tooth feels like it just bit a tiny rock, in your mouth.
Maybe I will go for the UN seeded lol.
I think grapes with seeds in tast a lot better. Grapes seeds are also supposed to be good for you. I will only buy grapes from the country I live in, mostly from farmers markets as I hope they are fresher and have travelled much less food miles
