What to do with a large amount of blackberries?

I am the lucky owner of a 20m blackberry hedge. Last years yield was about 15kg and thus year looks to be the same.

But here's the thing, 15kg is far too much to make jam of, so last year I experimented with wine. I got this kit https://brew2bottle.co.uk/products/better-brew-hedgerow-wine-kit-23l and just followed the instructions. And it was a great success, everyone who's tasted it have even been to nice to say it was bad or have actually complimented the wine. But I still have half the wine left and now it's time for 2023s harvest.

I'm still considering wine, jam and some juice but... What would you do with a lot of blackberries?
