Dad would have certainly loved these grapes! The bunch of purple grapes alone are sold for 2000 yen (about 12 pounds) so it's a good job we enjoyed them. They're called Shinano Purple and are seedless, as are the red and green ones. The red ones were the sweetest and most like the grapes in the UK. The green ones also had a sweet taste but also strong and wine-like, so they were my least favourite. The purple ones were not sweet but had a real full taste, very nice.
