Vignon is an alcoholic beverage served on Equellus.
Apollo orders this beverage prior to his encounter with Lacerta's lackey, Marco, in the nearby town bar. During his conversation with Red-Eye, the Cylon Centurion under Lacerta's control, Apollo comments that the Cylon wasn't missing out on the drink, despite the fact that he orders another at Lacerta's table (The Lost Warrior).
