Malted whiskey is a type of whiskey that is made from malted barley. The malting process involves steeping barley in water, allowing it to germinate, and then drying it in a kiln. This process converts the starches in the barley into sugars, which can then be fermented by yeast to produce alcohol.
Malted whiskey is typically aged in oak barrels, which gives it its characteristic flavor and color. The aging process can last for several years, and the longer the whiskey is aged, the smoother and more complex its flavor will become.
