What does 'natural colour' signify on a whisky label?

The term 'natural colour' on a whisky label primarily signifies that no caramel coloring has been added to enhance the whisky's appearance. When a whisky is described as having a 'natural colour,' it means that the color you see in the bottle is the result of its natural aging process in wooden casks, which imparts flavors and colors based on the type of wood and how long the whisky has been aged. Caramel coloring, often added to achieve a certain hue, is commonly used in many spirits, and its absence is what distinguishes a whisky as having a 'natural colour.'

This label choice indicates a transparency about how the whisky is made, appealing to consumers who may prefer 'pure' or 'authentic' products. While other natural ingredients do influence the flavor and overall character of the whisky, the 'natural colour' specifically refers to the absence of artificial colorings such as caramel. Therefore, option C accurately reflects the implications of this labeling choice.
