This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 醳 is uncertain. It combines 酉 (wine vessel) with 睪, which may contribute a phonetic element, but the original meaning is unclear.
The left side 酉 suggests a wine jar, and the right side 睪 is a complex shape. Without a clear meaning, picture an ancient wine vessel with an unknown label.
For エキ, imagine a mysterious wine jar labeled with an 'E' key: E-key -> エキ, unlocking the unknown.
