A Beer City in a weed country!

I met a guy who told me that Olomouc (pronounced Olomonts / Olmutz) was a beer city in a weed country. The reason was that Olomouc comes from Olmutz , which where supposed to mean the some of the raw materials you need from making bear in old german. Moravia was called hana , which also is supposed to mean hemp (weed) in old german.. He was very convincing and I have no reason for not trusting him, unless someone knows the true meaning of those words.

For now im just adding pictures. Text would probably come later.
