In a large pot, soak the mixed beans overnight in water to cover.

Drain and add fresh water to cover.

Cook at a simmer for 1 1/2 hours or until beans are just tender.

While the beans are simmering, heat a large skillet.

Mince the bacon and cook until it begins to crisp.

Add the onions and garlic, and cook over medium heat for 5 minutes.

Add all the spices and the ground Poblanos to the skillet, and cook for another 5 minutes.

Add the tomatoes with their juice and the beer.

Simmer for half an hour.

In another pan, cook the ground beef until the pink color disappears.

Drain and add it to the tomato mixture.

When the beans are fully cooked, drain them, reserving the liquid, and add the beans to the meat and tomato mixture.

Salt to taste and let the mixture simmer for about 1 hour.

If it is too dry, add some of the reserved bean liquid.
