Here the first sentence of Third-wave coffee's wikipedia page:
> Third-wave coffee is a term primarily in the United States coffee industry emphasizing higher quality, single-origin farms and light roast to bring out distinctive flavors.
I also strongly suspect your definition of "decently dark" is still below a medium roast. If not, I would be interested if you could cite a "decently dark" roast you have tried from a third-wave coffee shop.
