Cora in the north east only had Löwensenf and Alnatura from Germany. It depends on overall stock and indiviual supply chains between supermarket chains and regions.
The article is specifically discussing a shortage in Dijon Mustard in France.
Given the Super U reference, gp is presumably in France.
Yes, in France and I checked for Dijon mustard. I must keep the name of my Super U secret or we will have an invasion :)

I was in Bordeaux last week and they were out of Dijon mustard. It's the best for dressing and many classic sauces
