This is a common trick for home roasters called a melange. Roast 1/2 lb. to a medium roast and another 1/2 lb. of the same bean to a dark roast and mix together to get the best of both. I think I have only seen Blue Bottle do it commercially.I agree with aravenel on Peet's. The lesser of two evils when traveling, but only if I have exhausted all avenues to find a good pour over. Peet's roast too dark for my tastes.
