I would prefer some really good German wines rather than the liquors made here. But that is another question.
Flensburg for example used to be the MOST famous city of
rum in the past.
All the ship traffic was because of
rum in the older days.
Today, there is only one factory left.
I am not advertising, so i should not link to it.
Regarding subs, a lot of uboats were scuttled here in Flensburg "bay" at the end of the war, and still there are a few remains...
