Heat oil in medium saucepan over medium heat. Add cumin, garlic, oregano and sazon to pot. Cook until fragrant, about 30 seconds. Add wine; bring to a boil. Add 1 cup water, beans, bay leaves, brown sugar and vinegar; bring bean mixture to a boil. Reduce to medium-low and simmer, uncovered, stirring occasionally, until mixture thickens and ingredients come together, about 15 minutes.
Season soup with adobo; discard bay leaf.
Divide soup evenly among serving bowls. Garnish with onions and cilantro, if desired.
If your soup has a good consistency, but the beans haven’t fully absorbed the flavors of the herbs and spices, try this: Turn off the heat and let the soup sit, covered, 10-15 minutes more. This hot environment will encourage the seasonings to penetrate the beans, without allowing any liquid to evaporate, so your soup will look as good as it tastes!
