Mix bison, oats, 2 tablespoons ale, the salt and pepper in a large bowl until just combined. Shape into 4 (½-inch thick) patties with a slight depression in the center of each to help keep the burgers flat (they’ll shrink as they cook). Let burgers rest at least 30 minutes in the refrigerator; they’ll hold together better and stay juicier when cooked. Heat a grill to medium (350° to 450°).
Whirl garlic in a food processor until minced. Add cheeses and remaining 2 tablespoons ale and whirl until smooth.
Brush burgers with oil. Grill them, covered, turning once, until cooked the way you like, 6 minutes for medium. In last few minutes, grill split buns, turning once, about 2 minutes.
Arrange burgers on bottom of buns and top with sprouts. Spread bun tops with cheese mixture.
