I love apfelschorle, I drank it constantly while visiting Munich, I took 3 bottles back on the return journey intending to drink them once I got home, I'd finished them before I even reached Calais
I was going to start a thread about this topic as I wanted to know the proportions of apple juice to mineral water, but I just read that it's roughly 50/50.
I'll be stopping at a supermarket tonight to make my own, I wish we could buy it in Scotland
