Heat the oil in a large pot over medium-high heat. Add the carrots, red onion, poblano, bell pepper and 1/2 teaspoon salt and cook, stirring, until just starting to brown, about 10 minutes. Stir in the garlic, chili powder, cumin, coriander, cinnamon and a few grinds of pepper.
Add the lager and simmer until mostly reduced, about 1 minute. Add 2 1/2 cups water and the tomatoes. Stir in the black beans and pink beans. Bring to a simmer and cook, adjusting the heat as needed and stirring occasionally, until slightly thickened, 45 minutes to 1 hour. Stir in the cilantro.
