Tamdhu

Type: Distillery

Tamdhu is a whisky distillery on the banks of the River Spey, known for a maturation policy of 100% sherry oak, using American and European Oloroso casks, according to the producer.[1] Ian Macleod Distillers acquired it in June 2011 and relaunched the brand on 3 May 2013 with a 10 Year Old.[3]

What Tamdhu is known for

The clearest way to understand Tamdhu is through its cask policy. The producer describes maturation entirely in sherry oak, with both American and European Oloroso casks in use.[1] That is the useful distinction to carry into a comparison with other distilleries: the stated policy is sherry oak, not a mixture of sherry and ex-bourbon casks.

The distinction concerns the casks, not a promise that every expression will taste identical. No first-hand tasting is reported here, so the account below concentrates on the documented production history and releases.

From Saladin boxes to expansion

Tamdhu's own history describes it as an early user of Saladin boxes, a French invention that turns barley mechanically. It says the floor maltings were modernised with the boxes in 1949 and that ten were in use at one stage.[1] The fact sheet classifies the early use as Documented.

The producer also records a substantial period of expansion in the 1970s, when four stills were added in four years.[1] Those additions belong to the historical record; they are not presented here as a count of the equipment installed today.

Selected production and release dates

• 1898: Charles C Doig was hired as architect and engineer, according to the producer.[1]
• 1949: Saladin boxes modernised the floor maltings, in the producer's account.[1]
• 2018: the producer introduced the 12 Year Old.[1]
• 2019: the 15 Year Old launched as a limited release.[1]
• 2022: the 18 Year Old launched for the 125th anniversary.[1]

Story box: a founding and a return

Story title: a Victorian beginning, followed by a modern relaunch.

Founding story: the producer says a group of entrepreneurs came together to found Tamdhu in 1897. Wikipedia instead gives 1896 and describes a group of blenders. The supplied record classifies the founding year as Disputed.[1][2]

Turning point: Ian Macleod Distillers acquired Tamdhu in June 2011. The subsequent brand relaunch on 3 May 2013 introduced a 10 Year Old, establishing a dated return for the brand rather than evidence of permanent closure.[3]

Documented record: the acquisition and brand relaunch are separately dated in Ian Macleod's announcement. They answer the misconception that Tamdhu closed for good, without requiring the founding dispute to be settled.[3]

Understanding the return

The reopening chronology is disputed. Tamdhu's own account says Ian Macleod opened the doors again in January 2012, while Wikipedia, as quoted by Whisky Clan, gives May 2013 for the restart of production.[1][6] Prestige Malts describes the distillery as reopened in 2013.[5] Opening the doors and restarting production are not necessarily the same event.

Acquisition, reopening and brand relaunch are different events. For a reader following Tamdhu's return, the firmest separately dated markers in this record are the June 2011 purchase and the 3 May 2013 relaunch.[3] Keeping those events apart is more informative than compressing the whole revival into one year.

Reading the release history

The releases recorded in the producer's history show how the range developed after the relaunch. The 12 Year Old arrived in 2018, followed by the 15 Year Old as a limited release in 2019. In 2022, an 18 Year Old marked the 125th anniversary.[1] These are dated release milestones, not a declaration that every expression remains in the current range.

That distinction matters particularly when reading about the 10 Year Old. It is the expression named in Ian Macleod's 2013 relaunch announcement.[3] The announcement establishes its role at that moment; it should not be read as a current range list. For present-day expression names, use the producer's current information rather than treating an older article as a catalogue.
