Created and written by Tadashi Agi with artwork by Shu Okimoto, The Drops of God has had an unprecedented impact on the international wine market and the various wines featured throughout the series. Those wines often see massive increases in sales when the manga features them. “Tadashi Agi” is actually the pseudonym of a brother and sister writing team who have extensive experience as manga editors and are also serious connoisseurs of wine. The books are extensively researched, and almost certainly with great pleasure. The manga has inspired both a Japan and Korean live-action TV series.
