The Laphroaig PX Cask is a triple matured single matured whisky. Much like the Triple Wood, the PX cask is also firstly aged in ex-bourbon barrels, and then transferred to quarter casks. Now, what sets this apart from the Triple Wood, is that it has been finished in casks which previously held PX (Pedro Ximénez) sherry.
The PX Cask is a duty free exclusive and is bottled at 48%. This is a 1 liter bottling.
