Eelwasser

Eelwasser is a popular Ferengi beverage. Its was started by Sluggo and Vorp when the former tricked Vorp into drinking the bog water in the Bowog Bog. Vorp found it to be delicious, remarking "Mmm. Tastes like eel."

Eelwasser began production soon after, with bottle after bottle being sold, with Vorp and Sluggo's picture on them all. Several decades later, several competitors joined together to oppose Eelwasser and created Slug-o-Cola, which gained seventy-one percent of the beverage market. 

Nog often drank Eelwasser with tube grubs. 

In 2374, Eelwasser was reporting excellent profits, while Slug-o-Cola was doing quite badly. While posing as Lumba, Quark told Nilva that supporting Grand Nagus Zek and allowing equal rights for females would give Slug-o-Cola an edge over Eelwasser. 

Shortly after, Ferengi Commercial News predicted that Eelwasser was on its way to victory over Slug-o-Cola, which they predicted would soon be out of business. 

In 2376, the Eelwasser company joined forces with Brunt and Chek Pharmaceuticals to depose Rom. In his advertisements, Brunt claimed he now drank only Eelwasser and would make it the official beverage of the Nagal Residence. It was later revealed Eelwasser was involved in the conspiracy in which the involved parties forged a marriage contract.
