Sakura trees at Ohishi Distillery in the city of Kumamoto, Japan.
Being a bit weird is a great way to stand out from the crowd, and that’s true of distillers who choose alternative casks—they definitely want their whiskies to be noticed. Millions of casks made from American or European oak are maturing whisky in warehouses around the world, made from quercus alba and quercus robur selected for the flavors they lend to the spirit and their superior structural properties for tight cooperage. By comparison, the number of non-oak species that are used for casks is tiny, but the impact on the color, aroma, and flavor of whisky can be mighty. Some blenders dispense these whiskies into new recipes in small doses like a chef judging the balance of flavors in a spicy dish, but there are mavericks with nerves of tungsten that put their unadulterated alt-oak whiskies out there for judgment, knowing that their polarizing pours might only find an audience from those with alternative tastes. So take a look at some of these curious casks.
