Quarter Cask

Modern equivalent

125 Litres (Cask)

A small cask holding exactly one-quarter of a standard barrel, engineered for rapid maturation.

The quarter cask increases the surface area of oak relative to the volume of liquid inside. This deepens wood influence quickly, making it a popular choice for finishing whiskies or creating bold, punchy single-cask expressions.
