Sort and wash beans. Place in a large Dutch oven with water to cover 2 inches above beans; cover and let soak 8 hours. Drain, discarding water.
Remove casings from chorizo, and slice diagonally. Sauté chorizo and ham in olive oil 5 minutes or until meats begin to brown. Add onion, and sauté 10 minutes; add garlic, and sauté 30 seconds.
Stir in flour. Gradually add water, whisking constantly until sauce is smooth. Stir in beans, ham concentrate, and next 6 ingredients. Bring to a boil; cover, reduce heat, and simmer 2 1/2 hours or until beans are tender, stirring occasionally. Stir in spinach, and remove from heat. Spoon soup into individual bowls.
*For testing purposes, we used Goya ham concentrate.
