Edition 5 has a higher percentage of Garry Oak casks in the blend than any previous edition. Combining pale malt spirit with only peated spirit, it is also the simplest in construction.
In Edition 6, Garry Oak co-mingles with both Brandy and Sherry casks. The Brandy gives a bright filter to the savory spice of Garry Oak while the Pedro Ximénez sherry brings classic darker fruits with muted sweetness.
