The Bowmore Distillery was officially founded in 1779 on the island of Hebridean Island of Islay. They take pride in hand-turning their barley in the malting room in the traditional practice, something seldom done in the modern era. They dry the barley over peat smoke and mature the whisky in casks facing the sea.
Bowmore Dorus Mor single malt scotch is a limited edition of 10yr old scotch. Named for the storms that lash the coast to the islands where it's made, the Tempest is bottle at cask strength (careful!) and aged in bourbon barrels below sea level. It is released annually as "batches," where we presume that the taste may vary from year to year--the first release (batch 1) in 2009 with an annual release following of what appears to be be about 2,000 cases each year.
