A distillery standard bottling gains its distinctive character by careful selection of casks that are used for mixing the batches that are to be bottled. If the distillery manages to maintain the supply of casks and to ensure continuity in their new spirit production, it should not be difficult to minimize batch variation over the years.
Proper cask management is twofold: At first, it is about selecting the best possible casks for storage after distillation in the first place. The second aspect is selecting the best casks from the aged stock for bottling.It is the second point that is most crucial for the final quality of the bottled whisky. A good selection makes or breaks it.
The casks need to be nosed & tasted as well! If both master distiller and master blender are good at their jobs, they team up to create a work of art called whisky.
