Billy Walker is no ordinary Master Distiller. He is the one responsible for the legend of the Glendronach 18 and 21 that we have been drinking for the last 5-6 years. This legendary distiller retired in 2016 after selling Benriach, Glendronach and Glenglassaugh... but it just didn't feel right to him. He came back 3 years later, and nowadays, with 77 years old, he has won Master Distiller of 2020 after buying a Distillery, The GlenAllachie. Since then, GlenAllachie has taken all the prizes. And i mean ALL OF THEM. Their 10yo Batch Strength won gold in 2019, 2020 and recently was awarded Best Single Malt of the World by The World Whiskies Awards. Billy Walker is the reason behind everything. This 2019 expression appeared only in Speyside Spirit Festival, and it is a Single Cask Strength bottle, Port Pipe matured, with 59.2%abv and a deep copper color. On the nose, an amazing complexity. Orange Caramel, moca coffee; chocolate powder. Cupcakes, marzipan and tiramisú dessert. After a first sip, the aroma became more floral; chocolate; herbal; orange leaf. Mint. Passion fruit and dulce de leche. On the palate it is just perfect; tons of things happened here. Chocolate, pepper; red fruits and oranges. A second sip gave a lot more: orange chocolate, creamy cinnamon, and honey candy. A third sip changed again, giving me burnt sugar, brown sugar, creme brulee and dulce de leche. Just amazing. Aftertaste was close to be as perfect as the palate. Orange leaf, pepper, some sulphuric notes and salt. Chocolate, black tea and melon. Burnt sugar, maple syrup. You can get the idea of the profile. Overall, the awards this distillery is winning are well deserved. This is my third expression from them and all have been fantastic. I am eager to try more of this single malt, specially since Billy Walker specializes in cask selection. My score for this great whisky, is a solid 96 over 100.
