On the subject of commercial vesus home made,
Something I always remember when visiting Switzerland, they don't sell their good stuff to other countries.
That means the Emmentaler you buy in the US is authentic, but it's not nearly as good as the cheese you can get here.
I have never in my life had any sort of Emmental style cheese that can in any way compare to an 14 month Swiss Emmentaler
The Emmentaler, Gruyere, Appenzeller, etc. are all 400 times better here than what they export.
Don't want to crash your party, just to remind you that Swiss cheese still is king
