I would say that we extract from the bean much like we extract from the grain in brewing but neither is soluble. Things like antioxidants, caffeine, proteins, and tannins are extracted and with malted grains carbohydrates are broken down into sugars by the very enzymes that were created by the plant during malting.
So I mean protein will give body, roasting gives aroma/flavor but the cellulose plant cell structure is not soluble.
Only some components of the ground coffee are soluble in water..
Instant coffee is soluble in water.
Yes, coffee is in fact soluble in oil. This is because it contains soluble constituents. If a product is soluble in water, chances are its also soluble in oil.
Order a B-52 coffee sometime. Yes, they are soluble.
Some components of coffee are soluble in hot water (and they are solutes), some components are not soluble.
Coffee powder is partially soluble in water.
Only instant coffee granules are water soluble. Regular coffee grounds are "woody" and do not dissolve in water. Hot water will make the components in coffee granules come out, but parts of the beans will remain.

Coffee can be described as a beverage that consists of an infusion of ground coffee beans. Coffee can also be described as a seed of the coffee tree that is ground to make coffee.
No, you don't have to. But you will have to buy ground coffee, which is not as fresh tasting as home-ground coffee. :) Right, home-ground coffee may be more tasteful than saleing ground coffee. Because Ground coffee deteriorates faster than roasted beans because of the greater surface area exposed to oxygen. If you are a coffee lover, you HAVE TO get a coffee grinder. In general you will notice the difference fast!
It is heterogeneous because cream is not soluble in the coffee as sugar.
