We explain how the number of times a cask is used affects the strength of the extraction and the personality of the spirit.

Fill is the order of use of the cask.

In the Scotch industry, 1st-fill generally refers to the first time a cask is filled with Scotch spirit. This does not mean that the cask itself is new oak. For example, when a cask containing bourbon comes to Scotland and is used for the first time, it may become 1st-fill ex-bourbon.

expressionCommon roles
1st-FillRelatively strong influence of extractable components and previous contents
2nd-FillCask influence is muted and easy to balance with spirit
3rd-FillMore delicate cask influence, available for longer maturation
Re-FillA comprehensive expression for barrels that have been used multiple times

It's not a bad cask if you use it a lot. A refill cask may be more appropriate if you want to preserve the distillery's unique fruity, grainy and waxy character rather than a strong sherry impression. Conversely, casks with excessively low activity may not produce the desired maturation results, making management by the producer important.

To make the Maker Game easier to understand, the rule is that the cask used first has a greater contribution to price and flavor. In reality, cask condition and maturation goals determine price and quality together.
