Concentration, what is the percentage of soluble matter in coffee?
What about the extraction rate?
Remember what I said in that diary? Coffee beans cannot be 100% integrated into water, and soluble matter in coffee accounts for a percentage of coffee powder that was previously extracted. Besides, to put it more popularly, how much substance in coffee has been incorporated into coffee?
Therefore, the extraction rate is,
TDS/DOSE (gram weight of powder)
There is a very important concept that the reasonable extraction rate will be between 18% and 22%. If we extract too much, we will drink bitterly and have a mixed smell. If it is less than 18%, the coffee we often drink will be sour. It must be mentioned that whether it is espresso or filtered coffee, the extraction rate is in this category.
Add water: open the lid of the water tank and pour in the right amount of water (calibrated in a coffee pot).
Put coffee powder: the electric coffee pot has a special container for holding coffee powder, and the effect of adding filter paper is better. The amount of coffee powder is determined according to each person's hobby, generally 2 tablespoons and 1 cup coffee powder is appropriate. Then wet the coffee powder and filter paper with a small amount of boiling water.
Turn on: the electric coffee maker should be turned on after the preparation is ready, plug in the power supply and turn on the switch of the electric coffee machine.
Extraction: when the coffee in the coffee pot reaches the desired cup, turn off the power switch. At this time you can enjoy a cup of strong coffee:)
Cleaning: the parts to be cleaned include water containers, coffee powder containers, (if filter paper is used, discard it), but be careful not to spill water into the electrical part of the pot holder, let alone immerse the whole electric coffee pot in water. so as not to damage the electrical components and the control mechanism.
