"Espresso" re-baked coffee beans, lipids, mellow flavor, Italian blending of coffee beans

Espresso is a baking method.

Espresso is a baking method, and you can buy a bag of "Espresso" in the store, which refers to heavy-roasted coffee beans suitable for brewing into espresso. The importance of lipids has been discussed in the previous section. Emulsified lipids are the main source of alcoholic flavor, so Espresso often uses deeper baking to drive lipids to the outlet of the cell pores without spilling large amounts of coffee beans; by this time the baking temperature has exceeded 200 degrees Celsius, which may destroy the whole pot of beans in a few seconds. Therefore, the mastery of baking degree is undoubtedly an art.
