The oldest name on this list that stood out to me is Weihenstephan brewery, founded in 1040 in Bavaria, Germany. They have some of the finest lagers I have ever tried. If you enjoy crisp, refreshing lager beers, I highly recommend their beers. My favorite one is probably the Weihenstephaner Hefeweissbier, followed by the Hefeweissbier Dunkel. Note: I am not affiliated in any way with the company, I just highly enjoy…
Beer nazi here... Hefeweizen/weissbier is not a lager. Lagers are cold bottom-fermented beers. Hefeweizen is warm top-fermented beer.
That said, they do make excellent weissbier, and if that style is unfamiliar to you, you're in for a treat.
