First thing we need to do is cut the pork loin into 12 large chunks. Be careful to keep them even so that the portions are symmetrical and balanced. After they are cut, season them on both sides with salt and pepper.
While you are seasoning the pork, get the Instant Pot ready. Place the pork into the Instant Pot and add the beer. Next, add the onions, caraway seeds, garlic, and apples to the inner pot. Put the sauerkraut in last.
Set the Instant Pot to high pressure cook for 15 minutes. One the timer goes off, allow the pressure to naturally release. Give it at least 15 minutes to naturally release before you release any remaining pressure.
