So a K-cup or knockoff is basically a pre-packaged, disposable coffee filter, pre-filled with enough ground coffee to brew one cup. K-cup coffee is not the same thing as âinstantâ coffee â those water-soluble crystals that dissolve when you mix them in hot water. In other words: making instant coffee does not require a filter, but brewing coffee does.
Freeze drying is the modern method of making instant coffee granules. Itâs been used for around 45 years, though freeze drying has been around for use in laboratories far longer. Freeze drying works by removing water vapour under vacuum. As I understand it, instant coffee is made by making a very strong solution of coffee and then evaporating the water. The alternative to freeze drying is using heat to evaporate the water. Freeze drying is supposed to keep the coffee flavours far better than heat evaporation.
