So there is Pete's Word (Phil Ward), which is the Last Word with Laphroaig substituted for the gin.
The other night I discovered the Final Straw (Geoff Fewell) which is another Last Word variation with Laphroaig as the base spirit. I made it with Laphroaig 10 (substituted for quarter cask), Benedictine, yellow Chartreuse (substituted for MOF), lemon juice.
I was fearing something very sweet, but the intense smoky peat of the Laphroaig tricked my taste buds into thinking this was nicely balanced.
