This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 酭 is uncertain. It visually combines 酉 (sake jar) and 有, but the original semantic or phonetic role of 有 in this character is unclear.
Since the meaning is unclear, focus on the shape: a sake jar 酉 beside 有. Imagine a jar of sake that you have (有), but what it means is a mystery.
For ユウ, picture you (ユウ) holding a sake jar 酉 and wondering what this kanji means: you -> ユウ.
