I bought some Guinness beer a while back and can honestly say I did not like it. Too bitter for my taste. So, I left it in my pantry and a month or so ago had gotten some ingredients to make Frogmore Stew. I found that several recipes suggested using beer to steam the ingredients. I opened a bottle, but did not use it all, and did not pour the rest out, but loosely recapped it.
I do not recall if a short time later, I was either cooking a steak or some pork chops on the stove and thought of adding some of the beer. If it was steak, I also added some garlic.
I just fixed a couple of pork chops on the stove top, and opened some Guinness and added it to the cooking meat. I just had salt and pepper on the chops, but when the gravy cooked down, it was very flavorful.
