The Whisky 1901 Ledger Series is the bottler’s debut range, and it lands six single casks at once, running from an 11-year-old Glen Garioch to a 21-year-old Invergordon single grain, every one an age-stated single cask under £160. What’s worth a second look is the spread: Whisky 1901’s debut range, The Ledger Series, lands six single casks at once, running from an 11-year-old Glen Garioch to a 21-year-old Invergordon single grain, every one of them an age-stated, single cask release under £160.
Whisky 1901 announced the range today. The Miltonduff Aged 18 Years led off, bottled at the end of 2025, with five further casks bottled in April 2026 joining it this month. RRPs run from £125 to £160, and the bottles sell through Master of Malt and direct from whisky1901.co.uk.
The name comes from the old habit of record-keeping. Each cask gets documented and bottled for what it is, unblended and at single cask scale, rather than married into a house style. The casks span single malt and single grain across Speyside and the Highlands, with one sherry cask, one peated malt and one older grain breaking up what could have been six variations on a theme.
What is in the Whisky 1901 Ledger Series
Six casks make up the launch lineup. These are the official specifications from Whisky 1901, including cask numbers, bottling strengths and bottle counts. With a combined 1,152 bottles across the six, none of these will be around for long.
| Distillery | Age | Type | Cask type | ABV | Bottles | RRP |
|---|---|---|---|---|---|---|
| Miltonduff | 18 | Speyside single malt | Sherry | 51.2% | 180 | £160 |
| Tamnavulin | 13 | Speyside single malt | Ex-bourbon | 58.2% | 186 | £155 |
| Ardmore | 12 | Highland single malt (peated) | Ex-bourbon | 58.1% | 235 | £150 |
| Invergordon | 21 | Highland single grain | Ex-bourbon | 56.3% | 297 | £145 |
| Dailuaine | 12 | Speyside single malt | Ex-bourbon | 50.1% | 117 | £125 |
| Glen Garioch | 11 | Highland single malt | Ex-bourbon | 56.8% | 137 | £125 |
Three of these earn a closer look.
The Miltonduff 18 is the outlier on cask type, the only sherry maturation in the set, and the only one carrying medals out of the gate: Gold at the 2026 San Francisco World Spirits Competition and Silver in the 13 to 20 year Speyside single malt class at the World Whiskies Awards. Miltonduff is a quiet Speyside name near Elgin that rarely appears as a single malt, and an ex-sherry single cask from it is rarer still. Whisky 1901 describes dark dried fruit, candied citrus, caramel and wood spice.
The Ardmore 12 is the only peated whisky in the range, and a useful one to know about. Ardmore uses Highland peat rather than the Hebridean peat behind the big Islay names, which tends to read as softer and more floral than medicinal. Whisky 1901 points to floral smoke, damp moss, heather honey and toffee apple, with an ashy finish.
The Invergordon 21 is the curiosity. Single grain rarely gets an age statement this high outside specialist bottlers, and at £145 a 21-year-old grain is the value play of the group if the cask delivers. Expect the lighter, vanilla and coconut-led profile that long ageing in ex-bourbon gives grain whisky, rather than the heavier sherry weight some drinkers assume from two decades in wood.
The remaining three are ex-bourbon Speyside and Highland malts at full strength bar the Dailuaine. Whisky 1901’s notes run to green apple, vanilla custard and baked tarte tatin for the Dailuaine 12; orchard fruit, vanilla fudge and gingerbread for the Tamnavulin 13; and honeycomb, milk chocolate, golden syrup and earthy mace and cassia spice for the Glen Garioch 11. Those are the producer’s own descriptors.
Are they cask strength?
Mostly, by the look of it. Four of the six sit between 56.3% and 58.2% ABV, which is consistent with single casks bottled without reduction. The Miltonduff 18 (51.2%) and Dailuaine 12 (50.1%) are lower, which is normal for casks that have lost strength over a longer or warmer maturation, though Whisky 1901 does not explicitly label any of the six as cask strength. Treat them as single casks at natural or near-natural strength, and add water to taste.
Who is Whisky 1901
Whisky 1901 was founded in 2019 by Aaron Damiano Sparkes, originally as a Scotch cask investment business in London, with casks held in bonded warehouses in Glenrothes. That access to stock is how the bottling arm came about.
The two sides have now been split. The bottling business keeps the Whisky 1901 name, while the investment side has rebranded as The 1901 Group. The company says it will release between five and ten casks a year under The Ledger Series, alongside a single cask a year under its top range, The Collection.
Cask selection sits with Matt Chambers, a Keeper of the Quaich with 17 years in the Scotch industry, who joined as in-house Master of Whisky in 2025 after several years advising the company. Chambers selected the casks for Whisky 1901’s first bottling, the Glenburgie 35-year-old that anchors The Collection.
The Collection: the range above The Ledger Series
The Collection is the smaller, dearer line: one ultra-rare cask a year, chosen by Chambers. Two exist so far. Edition One, a Glenburgie Aged 35 Years, took Best Single Cask Single Malt in the Speyside category at the World Whisky Awards 2025, on top of earlier medals at the San Francisco World Spirits Competition and the IWSC. Edition Two is a Jura Aged 25 Years.
The price gap is the point. The Glenburgie 35 carries an RRP of £1,325 and the Jura 25 is £500, both sold by registration at the Whisky 1901 site. If The Ledger Series is the range you drink, The Collection is the one you put on a shelf.
Price and availability
The Ledger Series RRPs run from £125 to £160 per 70cl bottle. The whiskies are available now in limited quantities through Master of Malt and direct from whisky1901.co.uk. In the on-trade, Whisky 1901 lists pours at venues including Sushi Samba and the Sheraton Grand Park Lane in London, and at The Game Fair 2026.
Because these are single casks with fixed bottle counts, there will be no reruns. Master of Malt ships internationally across most of Europe, the US and beyond, so readers outside the UK can order, with import duty and shipping on top of the RRP depending on your country. Check your local limits before ordering, particularly in the US where state rules vary.
Our take
We have not tasted the Ledger Series yet, so treat the above as a release rundown rather than a verdict. On paper it is a well-judged opening hand: age statements across the board, a sherry-matured Miltonduff with two awards already, a softer Highland-peated Ardmore for contrast, and an older grain at a sensible price. The £125 to £160 band is competitive for single casks at these ages and strengths.
The one we would reach for first is the Invergordon 21 Year Old single grain. Older single grain at this strength is where independent bottlers often deliver the most per pound, and £145 for a 21-year-old is keen if the cask is as good as the spec suggests. The Miltonduff 18 is the safer bet for sherry drinkers, helped by those competition results. We will update this piece with first-hand tasting notes once we have glasses in front of us.
