It's quite funny, I really want the German pavillion to be a good representation of my country and actually trains here work pretty well

(just not tomorrow: the train drivers will be on strike...

)
And with the wines: yes, that's the point, they only export the sweet stuff while the dry wines are sold domestically. And in recent years even German red wines have become very drinkable. I have no idea whether sending wine would be allowed, I never take anything that resembles an agricultural product in anyway with me as those are not allowed to enter the US according to forms you get on the plane... However, there must be ways, I am sure they don't sell smuggled wine at Epcot
