Yes one of them is "Lindeman's" it is double fermented and got a cork like a bottle of sparkling wine. Might jump on the next plane and get some, that is GOOD STUFF.
Another favorite of Swiss folks and some Germans are so called "Radlers" or "Panaché", you mix half Sprite and half beer, very refreshing on a hot summer day.

And yes your Barth can go on a sea cruise ... really they got nice Roll-on Roll-off ferries just for that!
