Your $89.99 Bottle Could Be a 29-Year Sc

Thompson Bros Mystery Malt: Single Bottles & Six-Bottle Cases

“Whether you draw an older Bruichladdich or a youthful barrel from Lochlea, the promise is the same: an outstanding whisky experience.”
— David Othenin-Girard, K&L Spirits Buyer

Every bottle is $89.99, but what’s inside could range from a 4-year-old single cask to a 29-year-old Speyside. Each whisky was selected to deliver compelling value at the same price, while a significant portion of the possible selections would retail for many multiples of $89.99 in almost any other format.

There have been few greater pleasures in my 20-plus years exploring whisky than the opportunity to taste blind. It happens so infrequently, and I have officially exhausted my credits asking my wife to organize tastings, that I simply never get to do it. So when our friends at Thompson Bros first mentioned this project a couple of years ago, I was absolutely floored. They proposed sourcing a huge variety of single casks and bottling them without revealing any specific details until the bottle was opened. (continued below)

I assumed the federal regulators might object, but it turns out the required information can be concealed beneath the capsule. The craziest part of the project is the extraordinary effort the brothers have made to balance the quality of every six-pack. Buy a sealed case and you are guaranteed six completely different single casks, carefully selected so that the overall quality remains remarkably consistent from case to case. It is a ready-made blind tasting requiring virtually no effort, and the list of possible casks is genuinely exciting and unusual.

The project has now attracted significant international attention, and distillers increasingly see it as a calling card for their stocks rather than some goofy side project. As a result, the brothers have been able to source particularly compelling barrels for the series. I opened six and could not have had more fun. With a little care, you can easily avoid identifying the distillery when opening each bottle. Simply leave the foil around the cap intact, note which side conceals the round sticker underneath, and keep it facing away. You will have an instant blind tasting of the highest order. For several of these casks, this is the first expression from this distillery ever sold in the US.

K&L Notes

Perhaps the most exciting new product coming from Scotland in many years is the fabulous Mystery Malt from our friends at Dornoch Distillery. This limited release has been gaining serious momentum among collectors and drinkers who appreciate the extraordinary range of casks the Thompson Brothers have assembled, all offered at a remarkably compelling price. Not a single bottle in the lineup fails to justify the asking price, and a significant portion of the selections would retail for many multiples of the bottle cost in almost any other format.

Even more exciting, the distillery partners supplying these casks, often sourced directly from the producers themselves, have embraced the project as an opportunity to showcase truly exceptional barrels. Each cask is carefully selected to ensure that only the finest examples are included. In many cases, these releases represent the very first opportunity for U.S. drinkers to experience a new distillery. This batch features the first U.S. single barrels from Dornoch, Lagg, Nc’nean, and Kingsbarns. Whether you draw an older Bruichladdich or a youthful barrel from Lochlea, the promise is the same: an outstanding whisky experience.
