Blended Malt Whisky

In Scotch law the category is Blended Malt Scotch Whisky: a blend of two or more Single Malt Scotch Whiskies from different distilleries (no grain whisky). It must still meet all Scotch rules—matured in Scotland ≥3 years in oak casks ≤700 L, bottled ≥40% ABV, and only water or plain caramel colouring (E150a) may be added. On labels the full sales description must appear exactly as “Blended Malt Scotch Whisky”; older terms like “pure malt” are prohibited and non-category phrasing such as “vatted malt” can’t replace the required category wording. 

On Whiskybase, “Blended Malt Whisky” is used as a brand name to group these malts-only blends across many bottlers, so searching that brand returns a wide range of different releases rather than one proprietary brand.
