Scotch is a term used to describe any type of whisky produced in Scotland. Scotch can be made from a blend of different types of whisky from multiple distilleries, or it can be made by a single distillery. Single malt scotch is considered to be a higher quality and more refined type of scotch because it is made from a single type of grain and is produced at a single distillery, which allows for more control over the production process and a more consistent product. Single malt scotch is also typically aged for a longer period of time which helps to develop its complex flavours and aromas.
