Green Spot and the Spot Whiskeys

Type: Brand made at a named distillery

Beneath Dublin’s streets, Mitchell & Son once matured casks filled exclusively with Jameson spirit from Bow Street, according to the producer’s history. The merchant’s emptied sherry casks helped shape a whiskey that would outlive its own bonding operation: Green Spot.[1][3]

Today, Green Spot is a single pot still Irish whiskey made at Midleton Distillery in County Cork for the Dublin merchant Mitchell & Son. Its story belongs to the whiskey bonders, merchants who bought spirit from distillers and matured it in their own casks, rather than to a distillery called Green Spot.[2][3]

What Green Spot is

Midleton makes the spirit; Mitchell & Son supplies the merchant identity and family stewardship; Green Spot is the whiskey name. Mitchell’s work of maturing whiskey in its own warehouses ended when Irish Distillers took over production, maturation and bottling under an agreement with the family.[2]

Green Spot is single pot still, not single malt. Under the Irish whiskey GI specification, pot still Irish whiskey requires at least 30% malted barley and 30% unmalted barley and must be distilled in pot stills.[5]

The standard Green Spot no longer carries its former 10 year age statement. The 10 year old released in 2025 was a separate, limited anniversary edition, not a replacement for the regular non-age-stated whiskey.[2]

From a Dublin shop to whiskey bonding

The story began with a bakery, not a still. The business that became the merchant behind the Spot whiskeys describes itself as a seventh-generation family firm. Whisky Magazine identifies managing director Jonathan Mitchell as the sixth generation and Robert Mitchell as the seventh.[1][2][3]

Story box: A merchant’s whiskey, not a merchant’s distillery

• Founding story: William Mitchell opened a bakery and confectionery on Grafton Street, Dublin, in 1805. Mitchell & Son created the whiskey blend in the 1920s: the firm’s founding and the whiskey’s origin are separate events.[3]
• Turning point: Yellow Spot returned in 2012, bringing another historic colour back alongside Green Spot.[2]
• Documented record: Green Spot’s centenary was marked in October 2025, with a limited edition 10 year old released that year.[2]
• Sources and claim mapping: The merchant’s founding and the blend’s origin are supported by Difford’s Guide. Yellow Spot’s relaunch and Green Spot’s centenary are supported by Whisky Magazine’s account.

Bonding was hands-on work. Merchants bought new spirit in bulk, filled their own casks and managed maturation in bonded warehouses. Mitchell’s wine trade supplied the containers, which went to Jameson’s Bow Street Distillery to receive pot still spirit.[3]

Difford’s Guide describes a typical consignment of 100 casks, half previously holding dark oloroso sherry and half lighter fino. The whiskey matured for five years, was blended, then spent another five years maturing in Mitchell’s bonded warehouses on Fitzwilliam Lane.[3]

The merchant therefore shaped the finished whiskey through both the casks and the maturation, rather than simply distributing it after bottling.[1][3]

What the coloured spots mean

The colours began as practical marks in a working warehouse. According to Mitchell & Son, paint daubs on the casks indicated their age potential before they became the names of a revived family of whiskeys.[1]

An earlier bottle label adds another strand to the naming story. Difford’s Guide records that the whiskey was first sold as “Pat Whiskey”, showing a man against a green background, and connects that presentation with the Green Spot name.[3]

The warehouse marks and the early bottled presentation describe different parts of the whiskey’s identity. Neither makes every present-day colour name an age statement. In particular, the historical green mark does not make today’s regular Green Spot a 10 year old.[1][2][3]

When comparing bottles, read the age statement attached to the expression, rather than inferring one from its colour. The current producer listing explicitly names Blue Spot 7 Year Old and Yellow Spot 12 Year Old; regular Green Spot remains non-age-stated.[1][2]

How Green Spot survived

Green Spot reached its hundredth anniversary in October 2025. Whisky Magazine describes it as the only Irish single pot still whiskey to reach that milestone in continuous production. That unbroken run is what makes the merchant history remarkable.[2]

The younger whiskey had a stockholding advantage. The same account explains that the former 10 year old was easier to keep in stock than the older Yellow and Red whiskeys. Keeping it available meant a shorter wait for stock to reach its intended release age.[2]

After Bow Street closed, Jonathan Mitchell agreed that Irish Distillers would take over production, maturation and bottling at Midleton. Accounts disagree on the closure date, giving 1971, 1975 and 1977.[2][5][6][7] The family’s bonding role ended, but its stewardship and exclusive Irish distribution continued.[2]

Jonathan Mitchell made the stakes plain to Irish Distillers: if stock ran out, “the brand will die, and won’t be resurrected”. According to Whisky Magazine, the family refused to sell the brand outright.[2]

Green Spot’s historical customers reached well beyond the shop counter. Whisky Magazine records outlets including men’s clubs around St Stephen’s Green, the University Club, the Clare Street Club, golf clubs and army barracks, including Collins Barracks.[2]

Mitchell & Son calls Green Spot “The Living Relic of the Days of the Whiskey Bonders”. The producer’s phrase captures its unusual continuity: a merchant whiskey survived even after the merchant ceased carrying out the maturation itself.[1][2]

Reading the Spot whiskey range

The range now reaches beyond the four historical colours, taking in wine-cask versions and named single-cask releases as well as regular expressions. Mitchell & Son lists the following whiskeys; this does not mean every release is available in every market.[1]

Yellow Spot returned in 2012, followed by Red Spot in 2018. Blue Spot returned later, while Gold Spot also joined the broader range.[2]

Green Spot Château Léoville Barton debuted in 2015, using Bordeaux casks from the Irish-family-owned Léoville Barton. Château Montelena follows a different wine connection, using Zinfandel casks from Napa Valley. These names identify particular cask relationships, not extra colours in the old warehouse system.[2]

The bottle itself changed in 2011. Difford’s Guide reports that pressure from the US TTB led to the removal of “pure pot still” and the adoption of “Single Pot Still”. At the same time, clear glass replaced green glass.[3]

Common mistakes

“Mitchell & Son distils the Spot whiskeys.” For the distilling background, look to Midleton; for the merchant history, look to Mitchell & Son.[2]

“The colours are modern inventions.” Separate the historic cask marks from the revived expressions that carry their names.[1]

“Green Spot is a single malt.” Look under single pot still Irish whiskey: its barley includes both malted and unmalted grain.[3]

“Green Spot still means 10 years old.” Check the full expression name. The anniversary 10 year old and regular Green Spot are separate bottlings.[1][2]
