Bourbon By Nino Kilgore-Marchetti / March 20, 2015 One of the reasons the epicenter for bourbon in the United States is Kentucky is the easy access distilleries have to iron-free water filtered by the large amounts of limestone in the ground. This makes a huge difference, believe many, in the taste of this American whiskey here versus other parts of the US. Would it make sense therefore, if you need to use a bit of water to help open up the bourbon’s taste profile more, that it should also come from the same local sources as what goes into the whiskey? That’s one argument at least behind the recent unveiling of the Old Limestone bottled water out of Kentucky.Old Limestone, which recently garnered an award at a prestigious bourbon competition, is described by those behind it as being “the other half of a great bourbon.” It is said to be drawn from the same limestone aquifer Kentucky sits atop that bourbon distillers draw localized spring water from out of. The water in question, bottled at a source in Wilmore, Kentucky, comes out with traces of calcium and magnesium, but no iron, giving what’s in the bottle “a velvety smooth mouth feel” as you sip it.This special water is being positioned primarily as a mixing water that ideally partners alongside a good glass of bourbon. Suggested uses include in ice cubes you would pour your whiskey over, or perhaps added as a splash into your glass.Now whether or not you buy into this idea of terroir between bourbon and Old Limestone, the thought process behind it still seems fairly intriguing. I may order a bottle or two to try it out against local Portland, Oregon tap water, and will let you know the results if I do.If you want to order some for yourself, it is available on Amazon right now in various pack sizes of 1-liter bottles. Price wise expect to pay around $6 for 1 bottle, $8 for 2 bottles, $13 for 4 bottles, $20 for 6 bottles and $25 for 12 bottles.
