This is the para taken from my web site:-
They will be ripe when they give a little when squeezed gently between finger and thumb. They will also have slightly changed colour :- mid green to yellow green, and light red to dark red, depending on the variety. To pick the fruits, lift up the tip of a branch with one hand and pick off the hanging ripe fruits with the other hand. You will probably have to pick over the bush several times as the fruit does not all ripen at once and you want the fruit to be really ripe.
Checked mine today and almost ripe, but a few days to go. They will be 2 or 3 weeks earlier than usual this year.
Gooseberries freeze very well.
