Anatomy of roasted curved coffee flavor coffee beans

Now when it comes to the same baking color, the baking effect cannot be determined.

1. The air in this seam has a different thermal conductivity from the beans outside. If it will cause the two temperatures to be different. Most of the problem is that the air inside is much hotter than beans. For example, the oven is too hot, or the beans are not thoroughly dry. You will see that the middle is more scorched than the two sides. Generally speaking, after a scorch, the explosion will be faster, or not dense. At this time, it is very likely that some of the beans will taste astringent before they are baked. In addition, the overburnt part will taste dull. Like bitter soda cracker.

two。 The same bean may have different moisture content. This is about processing. This is more common in washed beans. Black spots will appear when the dryness is uneven. The result is also scorched and astringent taste. Wronged this bean. Everyone loves African beans. It always bakes well. This is also related to dryness in Africa. At least the beans are uniform, although the altitude is high, the beans are thick, 1 burst is always dense. Have you noticed that high-altitude beans from South America are not so easy to bake? Because the climate in South America is wetter. And it is not as expensive as African water, so there is often water to wash beans.

3. High altitude also makes the small inequality more obvious. Beans are thicker at high altitude and generally taste more complex because beans ripen more slowly. There are more subtle flavors (more obvious). But small defects, such as uneven moisture and uneven physique caused by lack of nutrition, will also be more obvious. Therefore, this will also cause the above uneven baking, baking can not produce the essential taste of beans.

4. The focus on the surface is usually due to the burning of the beans. For example, the barrel baking machine touches the metal bucket. To create the focus. Some baked beans will also be too close to the heat source, resulting in the phenomenon of scorching the surface.
