Unless it's chill filtered, any bottle of whisky that's diluted with water or allowed to sit undisturbed at room temperature for a couple of hours will develop a haze, says former Four Roses master distiller Jim Rutledge. “The haze will ultimately turn to ugly, nasty looking solids in the bottle,” he says.
Four Roses
Four Roses is a brand of Kentucky straight bourbon whiskey produced by the Kirin Brewery Company of Japan. The brand's distillery in Lawrenceburg, Kentucky, was built in 1910 with Spanish Mission-style architecture, and is listed on the National Register of Historic Places.
