Over the course of history, thanks to its multifaceted scent, palette of warm colors, and spiritual texture, wine has become an endless source of discoveries for food enthusiasts, connoisseurs, and poets alike. On top of this world, Yutaka Kanzaki stands as the most refined wine critic of his generation. Upon his passing, he tasks his estranged son Shizuku to compete with his adoptive son Issei Tomine for his legacy, urging them to find 12 elusive wine bottles known as the Drops of God.

Despite following intense oenology training as a child, Shizuku has no interest in wine and has always refused to taste it. Intrigued by the initial competition to win the right to live in his father's house, a previous chance encounter with apprentice sommelier Miyabi Shinohara helps him develop an interest in wine tasting. As Shizuku discovers his gift as an oenologist, he eventually decides to join the competition to discover the secret of his father's passion.
