Roasting caffeine Maillard reaction and caramelization of Arabica and Robusta beans

Boutique coffee is fresh coffee. Whether it's food or drink, of course, the fresh the better, and so is boutique coffee. High-quality coffee should keep the coffee beans fresh before making, including the preservation of baked beans, and grind the coffee beans into powder before making, which is also to retain its original and best flavor. And the way of making hand-made coffee is such a way to make high-quality coffee.
