David, my simple assumption would be... maturing another whisky that can be used with first-fill ex-bourbon. Then Glenfarclas would buy/trade for that cask.
As such, I would imagine that distilleries often trade used casks with each other to get the profile and 'distillery character' they so desire.

Leo, the point is they don't buy 3rd or 4th refill as they have used them previously so would continue to re-use them until they become a 'plain' cask as far as Glenfarclas are concerned.

Most don't use new wood but one exception is Glenmorangie who own whole forests worth in the Ozark Mountains area of the US. They consider themselves as pioneers in the field of using new wood, for example their 15yo, recently discontinued, was finished in new wood and their Artisan Cask range, wholly matured in this 'designer' new wood.
LeoDLion wrote:Why are 1st refill bourbon cask oily?
Obviously some distillers such as Glenfarclas, through experience, have learned that 1st fill gives the mature spirit an oily character. I would imagine from the tannins and other elements in the wood.
The following comes from Glenfarclas' new website (worth a look):Charring the casks releases carbon, which helps mellow the whisky, and hydrolysable tannins promote oxidative reactions such as ester formation from acids. Lignin flavour compounds such as vanillins, produce vanilla aromas. Simple sugars are responsible for a slight sweetness, whilst malty flavours come from the release of furfural, 2-methyl furfural and maltol, due to pentosan degradation.
