Baked beans have many eyebrow corners to pay attention to.
"before baking beans"
1. The ideal moisture content of raw beans is 11murl 13%. If you want to maintain this water content, you must rely on a good storage environment, and the humidity and temperature of the warehouse should be maintained at an average of 50% and 20 °C.
two。 Be sure to get rid of defective beans mixed with raw beans, even one defective bean can cause the whole batch of coffee to smell moldy, smelly gutter, or vinegar.
3. If you want to cook coffee beans quickly at high temperature, it will cause the dilemma that the outer layer is charred but not ripe on the inside. The coffee brewed from this kind of coffee beans will have a scorched taste and an unpleasant sour smell. On the contrary, if the temperature is too low and the baking time is too long, the beans will lose the flavor of raw beans and the coffee will be tasteless.

4. When baking beans, you need to pay attention to the aroma of coffee beans, so you must pay attention to the use of perfume or lotion. After baking the beans, you will touch the beans during the cooling process, so you must wash your hands in advance and do not apply any lotion on your hands.
5. The time point at the end of baking is called "roasting poing", which varies with the type of raw beans. Raw beans from Ethiopia and Papua New Guinea have a lower density, so they absorb heat faster, and if you also want to bake to medium-baked ripeness, the baking time will be shorter than other kinds of raw beans. On the contrary, the beans produced in Peru, Colombia and Indonesia with higher density take a longer baking time and deepen the roasting maturity as much as possible in order to maximize the delicacy of coffee beans. Even if it comes from the same origin and the same coffee farm, coffee may taste very different because of the state and baking conditions of each raw bean, so every step of the process must be paid attention to again and again.
6. After roasting raw beans into coffee beans, not only the color will be significantly different, but also the weight will be significantly reduced. Generally speaking, the ideal weight of coffee beans is about 85% of that of raw beans, and the ratio of sour to sweet is the best.

7. The next step in baking is to clean up the bean shell (chaff) and residue inside the baking machine, mainly with the silver film-silver skin (silver skin) that wraps the raw beans. If left alone, there may be a fire when baking beans, causing a fire.
8. Pick out the unripe beans (quaker, also known as Quaker beans and Quaker beans). Unbaked raw beans are obviously lighter in color than other beans and are easy to pick out.
9. Freshly roasted coffee beans have high carbon dioxide content, so the sour taste is strong. It is best to let the coffee beans ripen for a day or two, and the taste will be better.
10. Carefully record the baking time, baker, baking conditions and other information to create your own baking database.
