Maybe see if one of those roasters mentions the Swiss water process. IME it makes for quite good decaf (and I too have a hipster’s taste in coffee).
Wow, I had never heard of this before. The chemical process for decaf had always put me off before.

> When you see the Swiss Water® name, it means your favorite roaster offers 100% chemical-free decaffeinated coffee.
You may have just convinced me to switch to decaf...
