Coffee powder is ground into a powder of coffee beans, in which there are a large number of insoluble substances, while instant coffee is a water-soluble particle made from extracted coffee through a special process.
The most basic brewing method of coffee powder is drip filtration, which uses filter paper or flannel filter layer to hold the coffee powder and let hot water flow through the coffee powder to extract coffee. Instant coffee can be melted directly in hot water.
Coffee powder is made from roasted coffee beans, and water (either hot or cold) passes through coffee powder to precipitate aromatic substances, caffeine and other substances in coffee powder and dissolve in water to form coffee liquid, and its solid substances are insoluble in water.
Instant coffee is granulated after evaporating the water from the coffee liquid that has completed the extraction steps.
Therefore, using brewing coffee powder is generally called extraction. There are many kinds of extraction methods for coffee powder, such as pressure extraction (Italian), hand flushing, siphon, cold extraction, ice droplets and so on.
Logically speaking, making instant coffee should be called reduction.
Coffee powder has requirements on the water temperature of extraction (90-95). Instant solution doesn't matter.
