Shizuku Kanzaki is the son of renowned wine critic Yutaka Kanzaki, who subjected him to an unconventional education focused on wine appreciation from a young age. This upbringing led to resentment towards the world of wine, prompting Shizuku to leave home and become an average beer sales representative. After his father's death, Shizuku is drawn back into the world of wine as part of the will, which stipulates that his father's prized wine collection and estate will go to the person who can identify the "12 Apostles" of wines and the "Drops of God." Shizuku's chances of success seem slim, as he's competing against Issei Tomine, a veteran wine critic with no equal.
