Unsure if these beers are safe to drink

A little background: I tried this brewery, Lakefront brewery, out in Milwaukee and absolutely loved their beers. I haven’t had them in a while since they don’t sell them in distributors near me but I came across some while traveling this weekend and bought two six packs. However, I’m not sure if they’re good to drink. On the one pack, it says best by 9/9/22 and on the other it says bottled on 10/12/21. Unfortunately I have already gone home and can’t return the beers. Are they safe to drink? How long does beer take to go bad?
