Brown the ground bison in a stockpot over medium-high heat. Once cooked, remove the bison into a strainer and place onto a bowl, allowing the fat to drip off.
Add the extra-virgin olive oil to the stockpot. Once the oil is hot, add the onion and peppers and cook until they begin to soften. Add the garlic and cook for another two minutes or until fragrant, stirring frequently with a spatula.
Add the bison back into the stockpot, along with the diced tomatoes, crushed tomatoes, beans, beer, water, smoked paprika, salt, cumin, chili powder, and Worcestershire sauce. Open the can of chipotle peppers in adobo sauce and discard the chipotle peppers, adding the remaining adobo sauce to the stockpot.
Bring the chili to a boil and then reduce to a simmer. Cook uncovered for one hour, stirring frequently.
