A great coffee roaster should not only roast coffee to perfection and deliver on time, but will answer your questions by e-mail, social media, phone, and throughout the day. If you find a coffee roaster with those qualities, grow that relationship and then make sure you always pay them on time. It’s also smart to buy your own coffee equipment so if there’s ever a misunderstanding or a need to make a change, you can easily break up with your beverage supplier.
