The Glen Grant has been churning out spectacular single malts since the 1840s. In all that time, the legendary Speyside Scotch maker has never added anything to its permanent lineup as old as its new The Glasshouse Collection, a trio of elegant whiskies ranging from 21 to 30 years in age. Each one enters the bottle as an embodiment of the brand’s rich, ripened fruit flavors. Together, they form the swan song of master distiller Dennis Malcolm, who recently announced his retirement after 63 years.
