I almost had to give up on this one, so I fed the word berry into my online album and this one arrived. A photo I took last Autumn on one of my hikes with a camera and a stick. I think we call them “Vogelbeere” which would mean bird berries, because they are definitely not fit for human consumption, so I would not know if they were bitter or sweet, probably something in between.
And then I decided to explore further in my archives and what did I find? No idea what this is, but they could be red currents, but if the colour fits then go for it.
