Glen Spey 24 yo 2001 (53.8%, Maltbarn 2026, sherry cask, 148 btl.) leans grassy and malty on the nose with lemon-yoghurt and green fruit. The palate emphasizes sweet green fruits, barley, Seville orange and a strong load of grassy, bitter notes including quinine and grapefruit zest. It becomes austere and yeasty on the finish. The reviewer suggests it works well as a refreshing highball but is a challenging bottle for continuous sipping. Score: 83/100.
Orkney Single Malt 20 yo 2006 (51.5%, Maltbarn 2026, bourbon cask, 144 btl.) presents bright citrus, chalky minerals and beach-sand/sea-spray notes on the nose. The palate is lively with salted lemon, lime, mirabelle-like sweetness, grapefruit and ginger, backed by brine and cooling herbs. The overall impression is a crystalline, restrained Highland Park–type profile—consistent and austere by design. Score: 87/100.
Overall, Maltbarn's set divides into two camps: the sherried, fruit-forward blended malt and Glen Spey, and a group of lighter-coloured, mineral-lean single malts (Orkney, Glen Garioch, Caol Ila) that emphasize citrus, brine and restrained smoke. Bottle counts are small (98–150 each), and cask types are clearly listed on each label.
