The experiences related to coffee and coffee beans have always been recorded using Notion, but most of the time it serves as a "purchase record", with accounting functions being more important than the drinking experience and evaluation significance. The data is also not always complete. There are many empty spaces, some due to negligence in recording and not being filled in a timely manner, but more are about achieving self-consistency after breaking free from the reliance on data and techniques.
Baking or brewing, more and more people are starting to believe in their own intuition. Intuition is not a product of pure imagination, but rather a accumulation of experience. When the beans turn from green to yellow, it means the water is almost gone, the weight has decreased, the volume has expanded, and it's time to increase the heat. Increase the rotation speed a bit more, and after the heat is evenly distributed, the first crack will be complete, and some silver skin can also be removed.
The amount roasted at once is also very important. Previously, it was always a minimum of 200g, with a minimum duration of 15 minutes from the first crack, but the result is usually uneven heating, leading to a darker roast after the first crack. Controlling the amount of beans each time to not exceed 150g will greatly increase the margin of error. Properly roasting until the first crack, the resulting flavor will also be that of a normal first crack.
