Buffalo Trace Experimental Collection Straight Bourbon Whiskey Made With Peated Malt – This unique mashbill subbed in smoked peated malt as a flavoring grain and spent nearly ten years aging in new charred white oak casks. The nose is smoky and nutty, with hints of leather, mahogany, and cacao beans. The influence of peated malt provides a palate of slight smoke, brown butter, and a sweet toffee finish.
