A.D. Laws Four Grain Straight Bourbon, 47.5%

A mashbill of 60/20/10/10 corn/wheat/rye/malt, aged 3 years in full-size barrels. Nose is sweet, hot corn, but with an initial puff of sulfur; where's that from? Interesting splash in the mouth, with smooth wheat character knocking back the rye spice. Fairly hot, with some clove/cinnamon spice amping up as it winds down to the warm finish. Very active whiskey.
