- Bean origin: Not all beans have the same chemical composition.
- Bean roast: The chemical composition of the coffee bean changes throughout the roasting process.
- Size of coffee grindings: A consistent particle size is important, as the higher the surface area, the faster the extraction.
- Dry mass of coffee grindings: A different extraction composition.
- Temperature of extraction: The temperature dictates both the rate and composition of the extraction.
- Pressure of extraction: Has a similar effect as temperature.
- Time of extraction: Increasing extraction time allows for greater extraction.
- The water: The variable is less obvious, but it is clear that the chemical composition of water (i.e. dissolved ions) play a very important role.
