Extraction: understanding extraction
Now that we have good water and good coffee, all you have to do is make a cup of coffee. Almost every method of brewing coffee-espresso, poured coffee, cold coffee or French pressed coffee-has the same basic principle. Grind the roasted coffee into small pieces, then add water. Once the water touches the coffee, it begins to extract flavor compounds.
No matter what method is used, water always extracts different flavor compounds in this order: fat and acid, then sugar, and finally plant fiber. From a taste and body point of view, it looks like this:
Acid / oil-sweet / syrup-bitter / thin
