- Jan 3, 2001I was reading a very good book on the history of moonshine,
can't remember the name of the book, but in Appalachia (in the US)
mashing vats had open tops in the woodland, tree leaves and
bird dropping or manure was tolerated and even encouraged into
the mash. The moonshiners empirical experience had basis in science
as it provided the elements described below.
Of course today, we don't need manure or goose dropping, we can
achieve this through more suitable means.
