Yeats packs a whole philosophy into six short lines. The speaker says there are only two reliable pleasures or truths in life: wine, which enters through the mouth, and love, which enters through the eyes. Everything else, the poem implies, is uncertain or unknowable before death arrives. The poem then shifts from a general statement to a small, intimate scene: the speaker actually lifts the glass to his lips and looks at the beloved—and sighs. That sigh is the emotional core. It is not a joyful toast but a bittersweet recognition that even these simple, bodily experiences are fleeting. The mood is tender and melancholy, mixing physical pleasure with the shadow of mortality, as if savoring wine and love also means feeling how soon both must end.
A Drinking Song — Summary
Wine comes in at the mouth And love comes in at the eye; That's all we shall know for truth Before we grow old and die. I lift the glass to my mouth, I look at you, and I sigh.
