In a large sauce pan or pot, melt bacon fat on medium heat and sweat shallots, peppers and jalapenos for about 2-3 minutes to release some flavor.
Add sweated veggies and bratwurst to a crock pot alternating layers of veggies and brats.
Pour hard cider into crock pot until liquid just covers the bratwurst and veggie mixture.
Cook on high for 3-4 hours.
Once you have finished slow cooking, remove brats (be careful as they will have softened somewhat) and place them in a baking dish or other large container to cool.
Transfer remaining liquid and veggies to a large pot and reduce by ¾ on the stove at a medium-low heat, about 2 hours.
Once liquid has reduced, preheat grill to high heat and grill brats for 3-4 minutes per side to heat throughout and produce grill marks.
Spoon reduced liquid and veggies over brats and enjoy!
Notes
If you do not have a crock pot, you can use a french oven or large oven safe pot instead. Set your oven to 250° F and braise for 5 hours. Repeat same steps as above and enjoy.
