Warehousing - One of the mysteries of whisky. Three factors to be taken in to consideration:

The age of the warehouse – whether with traditional earth floored, low racking two casks high, or modern concrete construction with high racking to the ceiling – ten casks tall.

The location of the warehouse – the majority are at or close to the site of distillation; some, notably the larger companies, are stored centrally for convenience e.g.  Perthshire or Lanarkshire, thus reducing the specific localised effects, especially if a coastal distillery.

The site of the warehouse - some have notoriously exerted extra special influences on the whiskies aged within them; for example warehouse 1 at Ardbeg, or Bowmore’s best warehouse that abuts the very sea itself. Malts in these warehouses have aged differently to others on the same site.
