Hi all,
Having harvested my Bramley apples in late September, duly wrapped them up and stored them, I've just come to cook some, and found every single one of them with little brown marks all through them - there's nothing left to eat - they go right through the whole apple!

Also, one of them had a little pale coloured caterpillar type thing (wriggling, so definitely alive) on it, between the wrapping and the apple itself. Not sure whether this is linked to the brown marks or not. I've had a look at various websites, and I'm wondering whether it's 'bitter pit' which would be caused by a) not enough water (could be true with this summer of course) and / or b) lack of calcium. Has anybody any ideas please?
I'll just have a go at uploading a couple of photos - oh dear it won't let me - says the file's too big - sorry
