GlenDronach was founded in 1826 at Forgue in Aberdeenshire, one of the first distilleries to take a licence after the Excise Act, and draws its water from the Dronac Burn. The house style rests on full-term sherry-cask maturation rather than sherry finishing: spirit goes into Spanish oak from the start and stays there. For this release Master Blender Rachel Barrie married casks of three sherry styles — Oloroso and Pedro Ximenez, the pair GlenDronach is known for, together with select Amontillado casks, which the distillery had not used in a bottling before. Amontillado is aged first under a layer of flor yeast, as fino is, and then oxidatively, which leaves it drier and nuttier than either of the other two. The result was bottled at 46.8% ABV and released worldwide in September 2025 alongside a 40 Year Old.

Every bottle sold through Midnight Whiskey is sourced as an authentic, sealed product and inspected before it ships. Orders are packed with padded, glass-rated handling and require an adult signature (21+) on delivery; we do not ship to anyone unable to verify legal drinking age.

What sherry casks is The GlenDronach 30 Year Old matured in?

Three sherry styles: Oloroso and Pedro Ximenez, which are the distillery's signature pair, combined with select Amontillado casks. Master Blender Rachel Barrie married them together and the whisky is bottled at 46.8% ABV, which is 93.6 US proof. GlenDronach matures in sherry casks rather than finishing in them, so the sherry character runs through the whole thirty years rather than sitting on top of a bourbon-matured base.

What is the difference between The GlenDronach 30 Year Old and a GlenDronach single cask?

The GlenDronach Aged 30 Years is a vatting: several casks of three sherry types married together and bottled at 46.8% ABV. GlenDronach also releases single-cask bottlings, including thirty-year-old ones, and those come from one cask, carry a cask number, and are bottled at natural cask strength — which is usually higher. A single cask names its cask on the label. If there is no cask number, it is the vatted expression.

Why does The GlenDronach 30 Year Old use Amontillado casks?

Amontillado appears in a GlenDronach for the first time in the distillery's history with this release. It is an aged sherry that begins under flor like a fino and then oxidises, which gives it a drier, nuttier character than Oloroso or Pedro Ximenez. Used alongside those two, it adds nutty and savoury aromatics to a whisky whose usual register is dark dried fruit.
