Try looking up the story of how Odin stole the Mead of Poetic Inspiration. It's a fun one. Afaik mead is associated with poetry and being good at talking. It's associated with Odin because he's the one who stole it.
As for compatibility, the notion that old Norse religion is somehow exclusive to white northern europeans is neo-nazi nonsense. The Aesir pretty famously married a bunch of Vanir after the Aesir-Vanir war and a lot of them were married to giants or at least having flings with them. The gods themselves in the stories we have didn't give a fig about any blood and soil nonsense. Plus Odin is a rat bastard the ends justify the means scoundrel so it's not like he can be cross with you for taking what suits you. If you find something you like go for it.
