The Chemistry Behind Whisky’s Hue: What gives whisky its colour?
The process of determining the colour of whisky is a scientific one but let us not delve too deeply into the technicalities. Essentially, the colour of whisky is determined by the way the different compounds in the wood interact with the water and alcohol in the liquid. The presence of various compounds such as tannins and sugars play a significant role in determining the colour of the whisky.
When the coopers make the cask, they use a process known as toasting or charring the wood. This process helps to caramelise the sugars in the wood, which is responsible for the rich toffee and caramel Flavours that are so synonymous with whisky. In addition to this, the process also extracts colour compounds from the wood, resulting in the distinct brown colour of the whisky.
The hues of the spirits that mature in various casks differ depending on the type of cask and the rate at which colour is extracted. The ex-bourbon casks impart a light straw colour to the spirit, while the STR red wine casks bestow a darker, amber hue. Initially, port casks produce a deep ruby red colour, but as oxidation takes place, the colour mellows to a brick-red and eventually to a brownish shade. The possibilities for variations are truly endless.
The process of maturing whisky involves storing it in various casks, each imparting its own unique colour and flavour profile. Due to the unpredictable nature of colour development within each cask, it is difficult to control the final hue of the whisky that emerges. In order to ensure consistency across batches, blenders carefully select and mix casks together to achieve a harmonious flavour profile. However, even with this meticulous attention to detail, slight variations in colour may still be present between batches.
