So when entering the baking stage, how to determine the first explosion and the second explosion?

The most common way is to listen to the sound.

The sound of an explosion can be regarded as "suddenly like a silver bottle breaking water slurry splashing everywhere", Bibi peeling, sonorous and forceful.

After the end of the explosion, there will be a quiet period that varies from bean to bean, long or short.

After that, the sound of the second explosion will be much softer, which is described as "the sound of milk poured into the cereal circle".

The difficulty of listening is about 2, how to continue boldly without overheating into the second explosion? Sometimes it takes a lot of testing, especially when getting a new bean.

① generally judges the baking time of coffee beans by their different colors. Because coffee beans go through different baking degrees, their colors will be different, so color becomes the most commonly used basis for baking depth, but this judgment method is difficult to judge for some special coffee beans. For example, the color of Kenyan beans is generally much darker than that of other coffee beans. This is what I would like to remind you to pay attention to.

② roasted coffee beans when the smoke intensity, when the coffee beans into the second explosion will appear smoke state, so we can also judge the roasting degree of coffee beans from the smoke concentration, for this judgment method is not for all coffee beans, because of the different characteristics of various beans, it is necessary to constantly explore and summarize in practice in order to better control. Generally speaking, the best baking time for coffee beans is a moment before deep baking, because coffee beans will continue to be roasted because of their own heat after stopping baking, so if the time to stop is not a little earlier, it will make the coffee beans exceed the predetermined baking depth.

The best baking time for ③ coffee beans is that there is no absolute standard time, and the choice of baking time depends on personal preference. Bake a few more times according to your personal preferences, and find out how to control the reasonable baking time and baking depth, which is the baking curve of this bean.
