Bowmore fifty-year-olds are among the oldest Islay single malts ever released, and each bottling is treated accordingly — a hand-numbered run of a few hundred bottles at most, priced as one of the crown jewels of the distillery's prestige range. The casks drawn upon for these releases have invariably spent most of their lives in the No. 1 Vaults, the below-sea-level dunnage warehouse that is the closest thing Scotch whisky has to a slow-ageing chamber.
At fifty years the working assumption is that the whisky should not still exist in any state worth drinking. The oak, one imagines, will have long since consumed whatever delicacy the spirit possessed. In the case of Bowmore this assumption is repeatedly confounded. The distillery's lighter, fruit-forward distillate, combined with the exceptionally cool and humid maturation environment of the Vaults, produces fifty-year-olds that are still recognisably alive in the glass, still carrying tropical fruit and wax, and still — in the faintest of breaths — Islay.
Drinking one is less a tasting exercise than an act of witness. The whisky has been in wood since before most of its drinkers were born; it has outlasted chill-haze fashions, entire distillery owners, and the secondary markets that now determine its price. It is also, by most accounts, genuinely fine to drink rather than merely interesting to own, which is not something that can be said of every antique bottle.
To review a Bowmore 50 in the ordinary sense is almost to miss the point. It is a whisky one recommends with caveats — about price, about occasion, about expectation — and then, having recommended it, steps respectfully out of the way. Fifty years is a long time, and Islay knows how to keep its secrets.
