http://www.paradiseroasters.com/http://www.klatchroasting.com/i find those to be the 2 best roasters, though there are ofc others. what kind of coffee do you want to try? dark/light? earthy/acidic? no idea?
personally i like sumatran and african roasts, i do like central american roasts but i find them a but softer. i dont know how to offer an exact one since i dont know what you do like.
basically you cant buy a bad one from those 2, they are all good. dont grind you beans until you are about to make the coffee. even if you do you will notice how these coffees taste worlds apart from the overroasted burnt shit from basically every coffee place you have been to. ill give more thoughts if you want, lmk.
