The Prakal II mixed drink, or simply known as the green drink was a beverage that consisted of 87% Saurian brandy, with the rest being targ milk and Denevian mead.

Guinan heard about the concoction once on Prakal II and mixed one up for Data in 2367 for a taste test. Aside from stating the ingredients, he noted that it had an unusually high concentration of monosaccharides and fructose compounds, which Guinan interpreted as it being "too sweet." (TNG: "In Theory")
