The 6th release at 140.2 is fantastic. Heavily oaked, vanilla, caramel. Release 10 (138.8) is oily, sugary, oaky, full of caramel candy & vanilla. It is equally fantastic. I let several non-bourbon friends taste it neat and were shocked to find out it was 138.8 proof. So smooth. (Recently added 136 & 139.4 to my collection) Consistently the best high proof bourbons. Not a fan of the new style bottles & the juice inside. They taste thin and lack character.
