Glen Garioch

Type: Distillery and brand

A spring that could be neither seen nor heard helped revive Glen Garioch. Recovered distillery heat warmed greenhouses growing tomatoes. Both belong to the history of this single malt Scotch whisky distillery in Oldmeldrum, Aberdeenshire, whose official founding date is 1797. Its whisky has changed too, with a move away from heavily peated malt in the 1990s.[2][3][4]

What Glen Garioch is known for

A road runs through Glen Garioch’s premises, serving as a shortcut for townsfolk, according to Difford’s. It is a telling detail for a distillery so closely woven into Oldmeldrum, about 27 kilometres (17 miles) from Aberdeen. The producer places it in the Valley of the Garioch, “the Granary of Aberdeenshire”, and says a valley once home to six distilleries now has one.[1][2][4]

Peat provides the clearest dividing line in its whisky history. Heavily peated malt was produced until the 1995 closure, and the producer identifies Vintage 1995 as the last vintage whose barley was smoked with peat. Scotch Whisky describes production since the 1990s as unpeated, while recording small batches of smoky barley in more recent years.[2][3]

For readers exploring older bottles, the distillation period therefore matters more than a blanket description of Glen Garioch as “peated”. Historical production and later releases tell different parts of the story, rather than expressing one unchanging house style.[2][3]

From the Mansons to Morrison

John Manson was 27 when he founded Glen Garioch in 1797, according to Difford’s. His brother Alexander joined four years later, aged 19. The original premises included a brewery and a tannery: this was a broader working site than the distillery alone.[4]

Story verdict: An earlier founding

Claim: Glen Garioch may have distilled legally before 1797, potentially making it Scotland’s oldest distillery.

Verdict: Disputed

What the record shows: The official founding date is 1797. Scotch Whisky calls the earlier claim unsubstantiated.[3]

Evidence against or gap: No legal distillation before 1797 is established in the available record.

Earliest known source: Not established from the sources checked.

Sources and claim mapping: Scotch Whisky, founding date and earlier claim.

The Manson connection continued into the next generation. John Manson’s son, also John, joined in 1837 and later ran the distillery. John Manson & Company retained ownership until 1884. Accounts differ on the purchaser that year: Scotch Whisky names J.F. Thompson; Difford’s names J.G. Thompson & Company. They also date the merger with Booth’s Distillers differently, to 1935 and 1933 respectively.[3][4]

William Sanderson, creator of VAT 69, became a partner in 1886 and took full control in 1908. Glen Garioch joined the Distillers Company Limited in 1937. Production stopped during the Second World War, then resumed at low levels under barley rationing, according to Difford’s.[3][4]

The decisive modern purchase came in 1970. Glasgow broker Stanley P. Morrison, already the owner of Bowmore, bought Glen Garioch. That is the acquisition date, distinct from the later reference to Morrison Bowmore in 1990.[3][4]

• Turning point: Water shortages caused mothballing in 1968. After Morrison’s purchase, a new spring allowed production to rise substantially. Source and claim mapping: Scotch Whisky profile.
• Key person: Local JCB driver Alec “Digger” Grant found the new source on Coutens Farm. Source and claim mapping: Difford’s history.

The spring and the greenhouses

In 1972, manager Joe Hughes was appointed to find a new water source for Glen Garioch. Alec Grant discovered the answer on Coutens Farm: Coutens’ Silent Spring.[3][4]

The discovery allowed production to rise substantially. Difford’s explains that the spring earned its name because it could be neither seen nor heard. Grant’s son Kenny later became distillery manager and shared his father’s nickname, “Digger”.[4]

Story verdict: The silent spring

Claim: The spring was named for being neither visible nor audible, and the finder’s son later became distillery manager.

Verdict: Documented

What the record shows: Both details are recorded, with Difford’s explaining the spring’s name and the Grant family connection.[4][5]

Evidence against or gap: Kenny Grant’s appointment date as manager is not established.

Earliest known source: Not established from the sources checked.

Tomatoes were another unexpected part of Morrison’s transformation. Scotch Whisky records the installation of the heat recovery design used at Bowmore. At Glen Garioch, recovered heat warmed about 0.8 hectares (two acres) of greenhouses growing tomatoes. The producer associates its 1978 vintage with the year the “Greenhouse Project” came to fruition.[2][3]

Story verdict: Tomatoes grown with recovered heat

Claim: Glen Garioch used recovered distillery heat to warm greenhouses growing tomatoes.

Verdict: Documented

What the record shows: Scotch Whisky’s trade account documents the installation and greenhouse area; the producer supplies the vintage association.[2][3]

Evidence against or gap: Neither the precise commissioning date nor the project’s full operating period is established.

Earliest known source: Not established from the sources checked.

Sources and claim mapping: Scotch Whisky, heat recovery and greenhouse area; Glen Garioch, producer’s association with the 1978 vintage.

Production and the change in peat

All production goes to single malt, according to Scotch Whisky. Its production account describes a mash tun with a lauter system, stainless steel washbacks and short fermentations, though it gives no precise fermentation duration.[3]

Morrison’s expansion went well beyond securing water. Difford’s records an increase from two stills to three in 1972, then to four in 1973, when the distillery was largely rebuilt. A smaller wash still was later removed and placed outside Auchentoshan’s visitor centre, according to the same account.[4]

Three distinct milestones followed in the 1990s. The maltings closed in 1993, leaving their disused buildings on site. Peated production continued until the distillery’s 1995 closure. Glen Garioch then reopened in 1997. The maltings closure and the end of that period’s peated production were separate events.[2][3][4]

Production timeline

Reading the range

Founder’s Reserve and 12 Years Old form the core range listed by the producer, which describes its releases as small batch and non-chill-filtered. These descriptions come from the producer, rather than being findings from a tasting conducted for this article.[1][2]

Other named releases trace different approaches to maturation and the distillery’s changing production. Virgin Oak, released in July 2013, was described as the first Glen Garioch fully matured in virgin North American oak. Renaissance 15 Years Old was distilled in 1997 and released in July 2014, opening a four-part series.[2][4]

The producer also names 1998 Wine Cask Matured. Recorded vintages include 1978, 1986, 1990, 1991, 1994, 1995, 1997 and 1999. Together, they offer reference points across Glen Garioch’s production history, although their inclusion here does not indicate present availability.[2]

Visiting and reading further

The producer invites visitors to see its skills at work, and Difford’s describes visitors being welcomed throughout the year. Before travelling, use the official website to confirm booking arrangements, accessibility and age rules rather than treating that general invitation as a confirmed appointment.[4][6]
