Put the beans in an 8 quart Dutch oven. Add the kombu, bay leaf, celery, carrot, onion, garlic and fresh water. Cook for 1 hour and discard the kombu.
Cook for 30 to 60 more minutes, or until the beans are tender.
Meanwhile, preheat the oven to Broil. Roast the red bell pepper and chilies (see notes below or use jarred roasted red bells and canned mild green Ortega chilies). When done, set aside.
Roast the garlic cloves in the skin: preheat oven to 350 degrees F. Put individual garlic cloves, skins on, on a baking sheet and bake for twenty to thirty minutes, or until soft. When cool enough to handle, remove and discard the skins from the garlic.
Meanwhile, add the tomatoes, plus juices, beer, pasilla or ancho chile powder, cumin, thyme, coriander, salt, black pepper, and soy sauce to the soup. Cook at least 10 minutes longer.
Put the peppers/chilies and roasted garlic in the work bowl of a food processor. Add the soup in batches and puree the peppers/chilies/garlic and two-thirds of the soup. NOTE: I have personally had leakage issues when adding soup to my food processor and would opt for an immersion blender in the soup pot if you have one. Return to the pot and simmer for about 5 minutes more. Taste, and adjust seasonings, if needed. Serve hot, garnish with chopped cilantro.
