Oh Argus. I doubt many cheese sellers are as scary as me and at least the local cheese shops will let you try before you buy. I can't recommend any supermarket cheeses in particular but I do like that some Co-ops have a display of locally produced cheeses.

But my favourite Swiss cheese by a long way is Blaus Wunder BIO - you might find it in a larger supermarket and you will certainly surprise your Swiss friends who probably will not know that Switzerland even produces a blue. Search it out, it's (almost) as good as Stilton
