to strain spirits
醑 centers on the process of straining or filtering spirits, specifically alcoholic beverages, to clarify or refine them.
醑 combines 酉 (wine vessel, alcohol) with 胥, which likely contributes the sound and may relate to straining or filtering. The exact historical development of 胥 in this context is uncertain.
The left side 酉 represents a wine jar, and the right side 胥 looks like a hand holding a strainer over a vessel. Picture straining spirits through a cloth to make them clear.
For ショ, imagine a show where a master brewer strains spirits on stage: show -> ショ, and the audience watches the clear liquid drip through.
