Many scotch whiskies are aged or finished in sherry casks, but not all sherry casks are the same. Rachel Barrie, master blender for BenRiach, GlenDronach, and Glenglassaugh, sat down with senior whisky specialist Susannah Skiver Barton to explain the differences between whiskies matured in oloroso versus Pedro Ximénez (PX) casks. Do your own comparison with GlenDronach 12 year old and 18 year old—can you taste the different sherry influences?
By law, bourbon must be aged in a new charred oak barrel, but variables and distiller choices can affect the final flavor.
