Though it does not share the same name on the bottle, this…:

…is thought to be this:

And that is why Hirsch Reserve (not not be confused with Hirsch Selection) fetches more than $1000 per bottle, and is now little more than a memory shared by few.  I have had only three bottles of it since the late 1990’s.  I jealously guard the remaining half of what will surely be my last bottle.

None of these are from the old Michter’s (or any other pre-1979 name it had) distillery at Schaefferstown in Lebanon County, Pennsylvania.  The folks who now own the Michter’s name say that it is produced according to the Michter’s formula (at some distillery that they don’t even own).

But what was Michter’s and what happened to it?  A pretty good story about that can be found here.
