Trim the ends of each Brussel sprout, removing excess leaves. Cut the sprouts in half leaving the smallest sprouts whole.
Place a large skillet over medium heat Add the chopped bacon and sauté until crisp.
Add the sliced shallots. Sauté another 2-3 minutes to soften. Then add the Brussel sprouts. Stir and sear the sides of the sprouts for 4-5 minutes.
Pour the bottle of beer into the skillet. Add the salt and both peppers. Bring to a simmer and lower the heat a little. Stir and simmer until the beer has reduced to a glaze and the sprouts are cooked through, 12-15 minutes.
