A group of Taurons partake in this beverage in bottled form during the broadcast of Backtalk with Baxter Sarno featuring Daniel and Amanda Graystone. Later, Joseph Adama imbibes on canned Lethe while agonizing over his request to Sam Adama to kill Amanda in keeping with the Tauron "blood for blood" tradition. Sam later partakes on Joseph's stock of Lethe, after he has his fun in playing on Joseph's agony and confirming that Amanda remains alive, if only a bit scared from the ordeal (CAP: "Gravedancing").
- According to Greek mythology, Lethe is one of Hades' five rivers, reputed to cause forgetfulness in those who drank from its waters. Ghosts who traveled through Hades were required to drink is waters in order to forget their past life, as a prerequisite to reincarnation.
- Cans from production were later auctioned off by now-defunct auction house Propworx in a series of studio-sanctioned online auctions following the series' cancellation.
