Brora is one of the many so-called “mothballed” distilleries. Production ceased in 1983 and their remaining casks are currently sold as extremely limited releases. One of the oldest distilleries, Brora opened in 1819 and was called Clynelish until the actual Clynelish opened down the road 150 years later. The 2014 release of the 40 Year Old was the single most expensive bottle Diageo had released to date. Since then demand has surged for this Highland whisky.
