Refill American Oak Hogsheads

Refill refers to the process of reusing the cask after its use as a “first fill“. These casks have already given much of their aroma compounds to earlier fillings of spirit and only a small amount now contribute to the final whisky flavour. Whiskies mature very slowly in these casks, allowing the very essence of the distillery character to be revealed. They tend to be light, delicate and with the aroma of the original spirit. This can be done a number of times until it is deemed exhausted and in need of rejuvenation.

In malt whisky production, when pot stills are used to carry out the distillation, the process of vapour condensing within the still and then re-boiling is called “reflux”. The amount of reflux is influenced by the shape of the still and by the lye pipe. The more the lye pipe angles upwards, the more reflux is created. Therefore a still with an upward sloping Lyne arm (or Lye pipe) will have the most reflux resulting in increased copper contact, giving the lightest spirit, whereas a downwards slopping Lyne arm with less copper contact will have the least reflux and a heavier spirit.
The Scotch Whisky Association has defined 5 whisky regions: Lowland, Campbeltown, Islay, Highland and Speyside. On this website we have created our own regions: Lowlands, Islay, Islands, Highlands and Speyside. They offer flavours that are hugely diverse - and are all represented in The Classic Malts Selection.
In pot stills which are directly fired, a rummager is a mechanism that stirs the liquid in the still to prevent solids sticking to the bottom.
