A coffee expert once said: "the taste of Yemeni mocha is so diverse that it varies not only from different places, different tree species, and different batches, but also from each sack or even every cup." Because of his complexity and variety, how to bake the best flavor of Yemeni mocha is a challenge for coffee roasters.

The Yemeni mocha bean has bright acidity in light baking, with sweet fruit, spices and chocolate flavors, red berries, vanilla, cream, caramel and chocolate in medium baking, and obvious chocolate, nuts and spices in deep baking. We chose moderate baking in terms of baking degree, and the Yemeni mocha belongs to raw beans with less water, and considering the different sizes of beans, the temperature under the raw beans with low moisture content should not be too high, and the dehydration is accelerated in the early stage. retain moisture to develop flavor and taste. Preheat for 30 seconds, open the throttle to 3 until the color of the raw bean turns light green or white, open to 4, explode and open to 5 (maximum).

The caramelization reaction produces the best baking degree of nuts, chocolate, caramel and other flavors, which also balances the tricky acidity of mocha coffee to some extent. But it should be noted that the mocha is full of chocolate, but it is easy to taste rubber after baking.

The temperature of the furnace is 170 degrees Celsius, the fire power is 140C after opening the throttle for 1 minute, the throttle is unchanged, the temperature is 147.2 degrees, the bean surface turns yellow, the smell of grass disappears completely, the dehydration is completed, the firepower is adjusted to 110C, and the throttle is changed to 4.

In the 8th'00 minute, ugly wrinkles and black markings appear on the bean surface, and the smell of toast obviously changes to the smell of coffee, which can be defined as a prelude to an explosion. At this time, listen carefully to the sound of the explosion point, start to explode at 8: 23 ", turn the firepower down to 60 degrees, and the throttle is fully open (adjust the firepower to be very careful not to be so small as to be free of bursting sound), and put the pot at 197.9 degrees.
