> Also, I think it's fair to point out Riedel is European and has been around for 250 years.

It’s fairly common for companies to make different things for different markets, though. GM is American, and a century or so old, but didn’t exactly sell many Opel Corsas in the US, say. (For the sake of pedanticism, as of this year Opel is no longer a GM brand, but anyway...)
