Why is Charlotte coffee so sour/bitter?

I may get roasted for this but my wife and I moved to Charlotte 5 years ago from north east and have found that most coffee shops here have very bitter coffee. You can smell the bitterness when you walk in.

Coffee shops I go to include, The Hobbyist, Summit, Undercurrent and Giddy Goat. All are very soury in our opinion.

Does anyone know if this is specific to the type of bean they are roasting? The way they are roasting it (too much too little?)…or is it just simply the water they’re using?

When I say sour, I get a very strange bittersweet taste, and it smells fruity sour.

When I brew at home, I don’t get that sour smell. When I come back to the north east, I don’t get that sour smell or taste either.

Coffee experts, please tell me what’s happening.
