Peat is a type of fuel made from partially decayed vegetation, which is found in many parts of Scotland. It is often used to flavor Scotch whisky, giving it a smoky, earthy taste. PEAT is also used as a flavorer in other types of alcoholic beverages, such as beer and mead. The use of PEAT in Scotch whisky production has been a traditional practice for centuries, and it continues to be an important part of the flavor profile of many Scotch whiskies today.
