The strength of flavour in coffee capsules refers to the intensity and fullness of coffee flavour that the capsules provide. This parameter depends on several factors such as the amount and type of coffee used, the roasting level and the grit of the ground coffee. Coffee capsules usually offer different levels of flavour strength, which are indicated on the packaging, e.g. 1-5, where lower numbers indicate a milder, less intense flavour and higher numbers indicate a stronger, more robust flavour. Capsules with higher flavour strengths are often more roasted and can have richer, more pronounced flavours, which is ideal for those who like stronger coffee.
