This Glenfiddich 18 year old is a mix of Oloroso sherry casks and bourbon casks. It says Small Batch Reserve : after 18 years selected casks are matured in “small batches” for a further three months.

All large-scale whisky is a vatting of many casks, and these are always married or settled right before bottling, often in neutral casks. I’m sure small batch  is still pretty large-scale in the case of Glenfiddich, so it sounds like they are trying to convert something very common into something special. The essence of marketing.
