KNOB CREEK BOURBON, bottled at an honest 100 proof like all good bourbons were a century ago, is aged nine years in charred American white oak which lends this bourbon its maple sugar aroma, distinctive sweetness and rich, full-bodied flavor, giving it the distinction of being aged the longest of the Small Batch Bourbons. This extra aging allows it to absorb more of the sugar in the wood, giving it a slightly sweeter taste and nose.
