Edradour distillery (Scottish Gaelic: Eadar Dhà Dhobhar, "between two rivers") is a Highland single malt whisky distillery based in Pitlochry, Perthshire. Edradour is reputed to be the smallest distillery in Scotland.
Established in 1825, the distillery was traditionally run by three men but now there are just two. Only eighteen casks are produced each week. They have a tour which costs £7.50 and currently includes two drams and a nosing glass.
The stills are the smallest in use of any distillery in Scotland. Were they any smaller, they would be deemed by HM Revenue and Customs to be portable, with the implicit capacity for illegal production. -Source: Wikipedia
