Demisting test - mystery solved
- At the beginning of a run the commercial distilleries do a demisting
test to see if the spirit will cloud water at 45.7 percent abv. Cloud
water at the beginning of a run? Sounds like tails. IT IS. They are
testing for tails that have been left in the still and pipes from the
previous run. The high proof washes the tails out, and when they are
clear it's a go.
