ABV and Cask Strength
ABV is the percentage of alcohol by volume. Scotch whisky must be bottled at a minimum of 40% ABV. Cask strength is a method of not diluting the aged spirit to the bottling strength, but this does not mean that all bottles are the same strength. Final proof may vary between casks and batches.
How strength changes perception
| ABV range | Changes that may commonly be perceived |
|---|---|
| 40~43% | Accessibility is good, but the density and texture of the scent may feel light |
| 46% | A common choice that aims for a balance of flavor, texture, and drinkability |
| 50~55% | Flavor density and oily texture may increase, but alcohol irritation also increases |
| Cask Strength | It presents the whisky at a high concentration, but balance can vary significantly between batches. |
High alcohol content does not necessarily mean high quality. Alcohol may mask the scent, and a few drops of water may help the scent be recognized. It is a good idea to first taste the scent as is and compare it by gradually adding small amounts of water.
Maker Game's 40%=0.90, 46%=1.00, 55%=1.10, and CS=1.20 are balance multipliers that express flavor intensity. It is not a formula that guarantees actual organoleptic quality.
