> virtually nothing worth paying for in the middle

I presume you know this, but an awful lot of those craft brands in the middle (including some of the Whistle Pig line) are made by the same distillery in Indiana. Which doesn't mean that they are bad, but it does disincline one to trust any of the puffery one reads on a label: http://www.seriouseats.com/2015/09/best-whiskey-spirits-from...

I did happen across one brand recently that surprised me by having a genuinely authentic and interesting story. They are doing a sweet potato base blended with their rye cover crop: http://www.outsideonline.com/2040581/drink-your-sweet-potato...
