Why do immature currants fall off?

[mountaindweller]

I planted something around a currant bush and realized that there were red currants on the floor. I thought it were the birds first, but i realized that they fall off when you only touch them. Is something missing in the soil or the lack of water or is it the variety? They heave fruit for the first time this year.

fall of small berries blushing precociously is usually related to poor fertilization

red currant or black one?

fertilization problem is more common with black currant
