The quality of raw coffee beans determines 8% of the taste of coffee, so as long as you buy good beans, you can surpass delicious coffee at home.
1. The simplest and most primitive way-pan frying
Every family has a pan for cooking. Before there was a professional baking machine, coffee was baked in a pan for a long time, and the quality of the coffee fried in a pan may not always win compared with the professional machine. But the best quality coffee beans are artificially fried. In fact, many roasted seeds and nuts have such a situation. The advantage of the machine is stable quality, and it can be simply standardized and hyped! But the role of man is that machines can never replace it!
To fry coffee beans in a pot, first clean the pot used for frying coffee to remove the grease. Household pots have been used for cooking for a long time, and there must be a lot of residual grease on them. So be sure to clean it before frying coffee! In general, wash the pot and open fire to dry the water on it, then add water to boil it, pour out the water and then open fire to dry it! Repeat this for 1-2 times. Heat the pot surface to dry, and you can't see obvious grease! Open fire and heat. When the pan surface is dry and there is no moisture, add coffee and green beans! The amount should not be too much, 1-2 grams is appropriate! As for the use of electricity, it doesn't matter much whether it is gas or other heat sources. The key is to control the heat! This can be compared with other roasted seeds and nuts or fried foods. The whole process requires moderate and stable firepower. Use a small fire at first, and then adjust it slowly. Stir the coffee beans constantly when frying! At the same time, observe the color change of coffee beans!
if the color of coffee beans changes rapidly, but this change is not complete. This situation indicates that the fire is too big or the stirring frequency is not enough. If you feel that mixing is ok, there is no possibility of improvement. This shows that the fire is really too big! In this case, you should immediately turn down the fire and take the pot away, so that the temperature in the pot will drop quickly! After lowering, put it on the stove with adjusted firepower to continue heating and frying.
if the color of coffee beans has not changed for a long time (3, 5, 1 minutes, or even longer), the fire is too small. In this case, the firepower should be appropriately increased.
the color of coffee beans changes slowly, and this change is holistic and uniform, which shows that you have a good grasp of the heat! In this case, pay attention to the color of coffee beans and listen to the sound of coffee bursting. As the baking continued, the color of beans slowly turned yellow from light green at first, then turned brown, browned and finally turned black. In this process, coffee beans burst once during the change from yellow to brown, but this burst process is very short, sometimes it is not obvious, and sometimes it only takes 3-5 sounds to end, which is a burst. There was a burst in the process of brown changing to brown. The burst lasted for 2-3 minutes, or even longer, and the sound frequency was very high, like setting off firecrackers! This is the second explosion. The second explosion is very easy to detect. Under normal circumstances, the second explosion has just started, that is to say, almost 1 noises are heard. At this time, the ceasefire is stopped, and the beans obtained are medium baking-whole city baking. Characteristics of beans: the bean noodles are dry, not oily or slightly oily, and there are tiny black spots on the brown beans! The sound of the second explosion continued and the baking of beans deepened. When there was no sound at all, that is to say, the beans were basically dark and carbonized seriously. Of course, this is also a baking style, and many people like this burnt taste! Generally speaking, the beans are normally baked from the golden yellow to the late black state, and the ceasefire can be stopped at any time in the middle, and the coffee can be drunk! As for when to cease fire, it depends on your own preferences! In general, the deeper the coffee beans are roasted, the heavier the bitterness, and the worse the taste hierarchy and the lower the nutritional value of coffee. Fully carbonized beans are really unique in flavor, but they really have little nutritional value! Therefore, it is not recommended that you bake to this level. As far as our beans in Yunnan are concerned, if we don't like the slightly sour style, we suggest to bake them in medium and deep. The beans in Yunnan are slightly sour when they are baked shallowly at a higher altitude!
2. Microwave oven, electric oven
Many people choose to use microwave oven or electric oven. Many microwave ovens and ovens can't stir the beans inside. If this is the case. It is recommended not to bake too many beans at a time. At the same time, don't stack and stack beans! That is to say, spread the beans flat on the plate! Just one floor! . This can achieve good results without stirring! The color change and popping sound of beans are still the key to judge the baking situation of beans. Please refer to the relevant contents above in this regard. People who don't like coffee are the tools to buy roasted coffee. Here is a good suggestion for everyone. If you really don't want to fry in a pan and need to buy tools separately, I suggest you buy an electric oven with rotating function. There will be an iron cage in the accessories of this kind of oven. Put the beans in the cage, and then install the cage in the middle of the oven. This cage can rotate, and there are heating bars on the top and bottom of the iron cage. The kind that can set the temperature and time! This kind of oven has the function of a professional bean dryer to a great extent! The quality of baked beans is very good, comparable to professional bean baking machines. Generally speaking, the scale of coffee shop or coffee drink business is not too large, and this kind of oven can meet the demand!
Special note:
Recently, some friends have asked about buying our raw coffee beans, and after baking, they will have a taste-peculiar smell similar to diesel oil, kerosene or other things that can't be described with precise words. After specific inquiry, I learned that they were holding beans with barbed wire clips and baking beans with open flames on liquefied gas, gas and gas stoves! I would like to remind you not to do this, because it is not normal for the baked beans to have no odor! This is a very simple truth, no longer too much explanation! Generally speaking, if you don't want to buy special tools, you can fry them in a pan. Only with patience can you fry very good beans. If you find it troublesome to stir fry, there is no microwave oven or oven. It is recommended to buy cooked beans directly!
supplement: after the coffee beans are roasted, it is necessary to cool the coffee, so that the flavor of the treated coffee will be better! How to operate specifically, everyone can play by themselves. Bake your own coffee beans, not too much at a time. After baking, spread the beans flat on iron, marble and plates (iron or porcelain) and stir them. In this way, the temperature of the beans will be lowered soon. If possible, you can use fans, fans and other things that can accelerate the air flow to the beans to speed up the heat dissipation and cooling of the beans! After the beans are cooled, the silver skin is raised (removed). You can grind, brew (brew) coffee and drink it. Remember to add sugar and milk powder to friends who use ground coffee for the first time!
about temperature: generally, the temperature of bean noodles is controlled at: 23-25 degrees Celsius!
