kind of green-colored wine
醁 refers to a specific kind of green-colored wine. It is a rare character with a narrow, concrete meaning.
醁 combines 酉 (wine vessel) with 录, which likely contributes the sound. The character was created to name a specific green wine.
The left side 酉 is a wine jar, and the right side 录 looks like a greenish liquid being poured. Imagine a jar of green-colored wine.
For リョク, picture a green wine that tastes like a rich liqueur: liqueur -> リョク, and the green color matches the wine.
