Light Whiskey is something that's making a comeback. It came into existence in 1968. It came into being because consumers were moving away from Bourbon and more into clear spirits such as vodka or gin. Yeah, I know, perish the thought. But, what is Light Whiskey? Well... first and foremost, it is distilled between 160° and 190°. Contrast that with Bourbon or American Rye, which tops out at 160°. But, that's not the only difference. It must also be aged in used, charred oak barrels or new, uncharred oak.
What is was not designed to be was aged very long. Except, that wound up happening anyway, especially since its recent resurgence.
Bring in MGP of Indiana. They had barrels and barrels of aged Light Whiskey, and some folks got interested in it. They started ordering those barrels and while it isn't a huge market, it is growing in popularity. Thanks to distilleries like Cat's Eye Distillery of Bettendorf, IA, that buys MGP stock, and now you've got some distribution. Cat's Eye produces its Light Whiskey under its Obtanium Master Collection Series.
