strong wine, dense, thick
醲 centers on a rich, concentrated quality: a strong, thick wine, or anything dense and intense in character.
醲 combines 酉 (wine jar) with 農, which likely contributes the sound and the idea of richness or thickness, as in concentrated agricultural produce.
A wine jar 酉 filled with the essence of farming 農: think of a thick, strong brew made from the richest harvest.
For ジョウ, imagine a strong wine so thick it's like a 'jō' (丈) tall wave of flavor: jō -> ジョウ, and the dense wine overflows the jar.
