: During distillation, the spirit can reach nearly 95% ABV, but it must be under 94.8% to be legally classified as Scotch. It is typically diluted to around 63.5% ABV before being placed in casks for aging. Responsible Enjoyment
Scotch is distilled at much higher strengths (typically 70–85% ABV) then diluted with water before bottling. 40% became the industry standard because: alcohol percentage in scotch

Scotch whisky is one of the most regulated spirit categories in the world. Among its strict legal requirements—geographical origin, grain types, and maturation duration—the alcohol content holds a unique position. It serves as a preservative, a solvent for flavor extraction, and a primary factor in the mouthfeel and volatility of aromatic compounds. While the global standard for bottled spirits often defaults to 40% ABV, the reality of alcohol percentage in Scotch is a complex interplay of chemistry, law, and history. This paper aims to dissect the significance of alcohol percentage throughout the lifecycle of Scotch whisky, from the "new make" spirit to the final bottled product. 40% became the industry standard because: [Distillation: 60%
