You're changing reasoning with each post so I'm just going to quote the last one because you Abandoned the other one.
First, its not spiel. It's possibility. How Tommy looks will be based in part on his father's origins, and how a person looks Matters a Lot in Wrestling in case you didn't notice with all the race/ethnicity gimmicks around. Him being Brazilian would help a lot, since Brazilians tend to identify with anything that remits to them and is winning. We still consider Carmen Miranda the first Brazilian superstar even though she was born in Portugal to Portuguese parents and made her fame in the US.
Second, what in the hell is your reasoning for being German? German beer isn't good. Its only fame is Oktoberfest and the fact that the German immigrants founded the famous American beers a century ago (who are shat on by the world, rightfully). You want a decent Beer/Bar gimmick? Go Belgian or Dutch. But the main issue is, having a bar doesn't mean you have to be freaking European. That's just mind boggling. All nationalities have bars. Jesus.
