I have had at least 3 commercial beet beers, 2 were at least national and one was local.
Magic hat used to make a summer ale called “whacko”... it was light pink or so, I loved it. Super bummed when it stopped being made.
Ballast point makes an oatmeal stout called “red velvet”. Super dark, reddish pink... but tastes just like an oatmeal stout. It was a cool experience.
A brewery in St. Louis made a beet beer that I frankly didn’t enjoy at all. It tasted dirty, and a little sour (I’m not a sour beer lover).
So, it’s not as crazy as you think. It can be done nicely and it’s a cool thing.
