flushed, rubicund
酡 centers on a reddish complexion, especially from drinking or strong emotion: flushed or rubicund.
酡 combines 酉 (wine vessel) with 它, which likely contributes the sound. The character suggests a flushed face from drinking wine.
The wine vessel 酉 on the left and the right side 它 together suggest someone whose face has turned red after drinking: flushed and rubicund.
For タ, imagine a flushed person tapping their red cheeks: tap -> タ, and the tapping matches the flushed face from drinking.
