Concentration

In coffee brewing, concentration is an important factor, determining the coffee strength, taste and flavor. In specialty coffee, Total Dissolved Solids concentration is an important factor. Many people are particularly interested in caffeine concentration.

Europeans like concentrated coffee, whereas North American coffee lovers like coffee with a lower TDS concentration. Turkish coffee is the brewing method with the highest TDS concentration.

In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration. The term concentration can be applied to any kind of chemical mixture, but most frequently it refers to solutes and solvents in solutions. The molar (amount) concentration has variants such as normal concentration and osmotic concentration.
