Apart from the fact that I cannot drink alcohol (no not AA, I am allergic to the stuff), the kind of apples we grow will not make Cider. that needs a specific type of apple with a high tannin content otherwise the resulting drink is so sweet as to be unpleasant. We did make apple wine with them years ago, but even that was too sweet for us.
I don't know about G., but our fruit does not go to waste. We puree and freeze, juice and freeze, bake and freeze and most of the types we grow will keep in the shed until deep mid winter to be eaten as they are. Then of course there are the birds to be fed on anywhich do go off.
The ones at Erddig are sold to visitors and are used in NT cafes I beliieve.
