Glen Spey Distillery was established in Rothes, Speyside in 1878 and is owned by Diageo — one of few Speyside distilleries in the Diageo portfolio primarily used for blending rather than single malt releases. The distillery produces a light, grassy, floral Speyside malt using worm tub condensers that contribute to its characteristically clean, delicate spirit. Glen Spey is rarely seen as an official single malt bottling, making independent cask releases of particular interest to collectors. This Single Cask Nation bottling presents a single 14-year-old Glen Spey cask at natural cask strength of 57.5% ABV without dilution or chill-filtration — an unusual opportunity to experience this seldom-seen Speyside distillery.

Single Cask Nation is a US-based independent bottler founded in 2011 by Joshua Hatton and Jason Johnstone-Yellin. The company sources exceptional individual casks from Scottish distilleries and bottles them at natural cask strength without dilution or chill-filtration. Single Cask Nation was awarded Independent Bottler of the Year by Icons of Whisky in 2024, reflecting its commitment to transparency, quality, and accessibility in single cask whisky. The bottler has grown from sourcing one cask in its first year to releasing 15–18 expressions annually, offering its selections through a members-based whisky club and US retail releases.
