The 45 Years Old will launch exclusively in global travel retail, with 250 individually numbered bottles available worldwide for a recommended price of £7,500.
The whisky was matured in an oloroso sherry cask and has been bottled at 41.5% ABV without chill filtration or added colour. It is presented in a bespoke Glencairn crystal decanter with a gold stopper, encased in a high-gloss wooden presentation box. Each pack also comes with a metal certificate signed by Tomatin's master distiller Graham Eunson.
Eunson said: "This is a remarkable moment for the distillery, as we reveal the latest premium aged-statement single malt whisky in our portfolio.
"Our 45 Year Old is a robust but complex single malt with a varied tasting profile that combines succulent fruit flavours with smooth, salty caramel, and a light sherry influence. Its rarity makes it perfect for a truly special occasion and the ideal addition for global collectors.
"Tomatin’s history tells a great story of craftsmanship and the perseverance of Highland whisky-making, and our 45 Year Old is a testament to this heritage."
