The Big Difference Between Scotch and Whiskey
The big difference between single malt scotch and single malt whiskey is that scotch whiskey must be distilled and bottled in Scotland and matured in oak casks for at least three years. Anything distilled elsewhere has to go by another name, otherwise it’s fraud.
Scotch whiskey has four raw ingredients – malt, peat, water and yeast. Producers begin by malting the barley and heating it over a peat fire to make a “whiskey mash.” They then combine it well to ensure that it will ferment.
After a couple of weeks, the base becomes fully fermented. Compounds in the grains break down and turn into alcohol. Once the alcohol content reaches the desired level, producers drain the mixture to remove any solids, keeping the alcohol content.
Distillation comes next. Here, producers heat and vaporize the alcohol into a liquid in a distillery, leaving behind impurities. They then collect and sort the distillate, removing volatile and potentially toxic compounds, such as methanol and acetone.
The final step is to age the whiskey or scotch in wooden barrels, usually for a minimum of two years. Aging methods can include oak, charred barrels, or those soaked in sherry.
Different Types Of Whiskey
Whiskey comes in a variety of forms.
Rye whiskey for instance, is a type of whiskey that uses at least 51 percent rye mash. In the USA and Canada, producers aged rye whiskey in oak barrels. It tends to have a slightly lighter body than conventional barley-dominant whiskey.
Single-malt whiskey refers to whiskeys made with just one type of malted grain, instead of a mixture. This is different from a single cask whiskey, which is a bottled whiskey that comes from only one cask
