In a large, heavy pot, heat the oil over medium-high heat. Add the meat and Essence, and stir with a long-handled wooden spoon to break up the pieces. Cook, stirring, until the meat is brown and cooked through, about 5 minutes. Add the onions, garlic, jalapenos, chili powder, pepper flakes, paprika, cumin, oregano and salt, and cook, stirring, until the onions are soft, about 4 minutes. Add the tomatoes and their juices, beer, and stock. Stir well and bring to a boil. Lower the heat to medium-low and simmer, uncovered, until the meat is tender and cooked through, about 1 hour, stirring occasionally.
In a small bowl, dissolve the masa in the water and stir to make a thick paste. Add to the chili and stir to incorporate. Cook, stirring occasionally, for 30 minutes. Remove from the heat and add the cilantro. Adjust the seasoning, to taste.
Ladle into chili bowls. Sprinkle with grated cheese and minced onions. Serve with hot cornbread, muffins or garlic bread, as desired.
