Intensity in coffee capsules refers to the degree of roasting of the beans and the overall flavour profile that results. There are several levels of intensity - from Blonde (light roast) to Medium (medium roast) to Dark (dark roast). Light roast emphasises the subtle and fresh flavour nuances of the coffee with a higher acidity, while medium roast offers a balanced mix of sweetness, acidity and bitterness, creating a harmonious coffee experience. Dark roasting delivers intense and robust flavours with lower acidity and more bitterness, often with a hint of chocolate or nuts. The choice of coffee strength depends on personal preference and the expected flavour profile.
