Illegal Whisky Distilling In The U.K.:
Long before Charles Dickens wrote about illegal underground drinking dens in his book ‘Barnaby Rudge’ such dens existed.
They made their own drinks. They still do. I know there is at least one in Moray, and probably a great many more. Dating from the 1700’s.
They take it to a new level now, because it is continuous, they can mature the whisky ’til it compares with anything on the market.
They are not only in Scotland either.
