Tamdhu 1990 20 Years Single Malt Whisky

Tamdhu Distillery, nestled in the heart of Speyside near the village of Knockando, has long relied on Scotland's railway network for its survival and growth. The Strathspey Railway, operational from 1863 to 1966, served as the distillery's lifeline—transporting essential raw materials like barley and coal via Dalbeallie Station (later renamed Knockando Station) and shipping mature whisky casks to markets worldwide. Today, the historic station building functions as an exclusive distillery shop, preserving this rich heritage. The production facility boasts an 11.8-ton semi-lauter mash tun, nine Oregon pine washbacks with a 59-hour fermentation period, and three pairs of copper pot stills. Tamdhu operates 20 warehouses—comprising traditional dunnage, racked, and pallet systems—with four additional pallet warehouses currently under construction. In 2019, the distillery achieved an annual production capacity of 3.1 million liters of pure alcohol, conducting 16 mashes weekly. A defining characteristic of Tamdhu is its exclusive maturation in premium Oloroso sherry casks crafted from both American and European oak, resulting in a distinctive, robust sherry-forward flavor profile. The core portfolio includes Tamdhu 10 Year Old (matured in first-fill and refill sherry casks), the annual Batch Strength series (currently on its fourth release), Tamdhu 12 Year Old (launched globally in August 2018), and a limited edition 15 Year Old. To commemorate its 120th anniversary in 2017, Tamdhu released an exceptional 50-year-old single malt matured in first-fill European oak sherry butts. The distillery also offers the Dalbeallie Dram series, with its second edition recently launched. In recognition of Distillery Manager Sandy McIntyre being honored as 'Manager of the Year 2019' by Whisky Magazine's Icons of Whisky Awards, Tamdhu introduced the Distillery Manager's Edition. Additionally, 2019 marked the debut of Tamdhu's travel retail exclusives: Ambar 14 Year Old and Gran Reserva First Edition, alongside the opening of an in-house cooperage for cask maintenance and quality control.
