Dufftown – 2010 15 Year Old Infrequent Flyers Batch 20

Dufftown 2010 15 Year Old is a single cask Speyside single malt, released in Alistair Walker's Infrequent Flyers series as Batch 20. It was distilled in 2010 and bottled in 2025, and 290 bottles were drawn from cask 806200. After its main maturation, the whisky spent around five years finishing in a Pedro Ximénez sherry puncheon. The concentrated nature of that cask gives a fuller, more intense sherry influence alongside Dufftown's Speyside character. It is bottled at natural strength, without chill filtration or added colouring.
