Hi, can only help with the items I too have needed, white wine vinegar, I bought this in Eurospar, but you can get in any migros or coop on the label will read
Weißweinessig
Brown sugar you can get in most supermarket homebaking aisles should be packaged as
Rohzucker Worcester Sauce you can buy at any migros sometimes in baskets under the fish or fresh butcher counter and is L & Ps
Chargrilled Peppers in oil have seen these on shelves beside pickles also in Migros
Unfortunately can't help with the rest although I do get fennel seeds from local asian store, maybe you will get these other ingredients in stores such as this.
Try the butcher counter for your ribs, and hope your sticky ribs turn out as they should, take it all ingredients are for this?
