That name'll fool ya.. the "Dew" brings on the notion of water droplets on the countryside foliage.. but it's really named after one of the craftsmen "Daniel E. Williams". Brother B is right- it's Irish (as is Powers also in that brief list).
But Brother B is incorrect, partially at least, in his declaration of authentic Scotch manufacturing. Maximizing the output of a great product is a no-brainer, however, when the marketing dept. projects an image of down-home artisan craftsmanship but in reality it's not much more than a cold, stainless steel factory.. that ain't right.
The old school touring facilities are for the tours. Whiskies are stored all over, bottled in facilities other than those that project the artisan image, and sometimes do not contain water from the region the scoth is named from. Islay scotch is supposed to contain water from only a specific region in Scotland, but at times it ain't so. McClelland's Islay is marketed as such, but it's a blend.. so it could contain spirits created from other regions.
Purists do complain of these unscrupulous, borderline devious, practices. And I thank those Scotch-snobs for exposing these crimes.
