While I know this is not a place to tout specific publications the new issue of Whisky Magazine is a must read for all Bourbon enthusiasts. While it normally trends more toward Scotch, this issue, entitled "50 years of Maker's Mark" has a Special Report on Bourbon and explores many trends in Bourbon with much insightful discussion. Kudos to Chuck Cowdery for his very adept comparisons on the "age" issue with Bourbons and in comparison to Scotch. Most interesting to me is the general agreement that Bourbon ages twice as fast as Scotch and therefore a 5 year old Bourbon is equal to a 10 year old Scotch.
