Peat

“Peat” isn’t a legal whisky category; it’s a style cue. Bottlers use “Peat” (sometimes as the front-label name) to signal a smoky, peated profile while the bottle still carries a proper sales description such as Single Malt Scotch Whisky or Blended Malt Scotch Whisky. Scotch labelling rules define the categories and control regional words, but do not create a category called “Peat,” so the term serves as branding/descriptor rather than a legal class. 

On Whiskybase, “Peat” is used as a brand label to group these releases across bottlers; examples include Peat Islay Blended Malt Scotch Whisky entries from Elixir Distillers / Speciality Drinks listed under the “Peat” brand page. Searching that brand yields many bottles rather than one proprietary product line.
