I think that we are starting to see an easing of the rye shortage, with producers bringing more and new ryes to the market. We are at the beginnings of a resurgence of the rye spirit. In the last 12-15 years or so, I've been unhappy with the rye shortage, as well as with the limited rye availability
here in my state, MI. (None of the High West ryes or Whistle Pig are available here in MI, or example.)
I just checked the most recent listing of straight ryes approved for sale by the MI Liquor Control Commission, showing >25 ryes. The number of new ryes in the listing include: Jefferson's Rye, Knob Creek Rye, George Dickel Rye, Colonel Taylor Rye, and Woodford Reserve Cask Rye (and this in a state somewhat more restrictive on spirit variety).
