We distil our barley wash at Penderyn Distillery in our unique copper still which was designed by Dr David Faraday, a descendent of Sir Michael Faraday. The technical innovation of our still produces not only a barley spirit of great complexity, depth and finesse, but also removes almost all of the undesirable chemical compounds which a conventional two or three pot system cannot. It is here that Penderyn starts to differentiate itself from traditional Scottish and Irish whiskies.
Our new spirit is combined with water from the Penderyn Distillery’s natural spring, located underneath the distillery, and is thus reduced to 63.4% A.B.V. - our cask strength.
The spirit is then filled into casks for maturation. We spare no expense buying the finest Buffalo Trace bourbon casks for the first part of the maturation and we "finish" the whisky by transferring it into Madeira barriques from Portugal for the “flag ship” Madeira Finish brand or a range of other high quality finishes including Oloroso Sherry, Vintage Port and occasionally old Islay whisky barrels.
