The limestone shelf where the distillery is located is key to crafting the unique taste of Maker's Mark – the only distillery with its own water source and watershed. Kentucky limestone filters out iron from water, which is unpleasant in bourbon. The pure calcium- and magnesium-rich water surrounding the distillery makes better drinking water and a better sour mash in which yeast can flourish.
In addition to being stunning to look at, these gleaming copper stills are key to our double-distillation process, which removes impurities for a more refined sipping whisky. As demand grew, our friends at Vendome Copper & Brass Works fabricated and helped us install an exact replica of our original still, creating this cool mirror illusion in our stillhouse and ensuring every drop of Maker's is still made the same way as Bill intended.
