Not explicitly about brewing, but
The A Word from the BBC has a major subplot about a family taking over a microbrewery in the Lake District. Given that it's been well-received and is current (3rd series just started) I imagine it will be available on a US platform.
Oz & James Drink To Britain (apparently renamed to James May Drinks to Britain in the US) is a pleasant enough travelogue/pub crawl/documentary where they visit various drink producers (beer features in most episodes somewhere), submit some homebrew to a competition and so on. It's kind of a Top Gear for drinking (so as more about the presenters than cars/drink) but it's engaging enough, I personally preferred the predecessor
Oz & James's Big Wine Adventure which was going round French vineyards.
There's
lots of British TV set in pubs (not least featuring heavily in our big soap operas like Eastenders and Coronation St) but
Early Doors is one of those that didn't get much attention at the time but has retained a cult following, I guess it's a bit like if Cheers was set in a northern English pub - a bit more dour, pretty slow moving but worth a watch. Mitchell & Webb's
Back is apparently returning for a second series this year so may have some profile across the pond - they play brothers taking on their father's pub. I found the first series OK, IMDB's 7.3 seems about fair.
Also a shout out for the film
Sideways - it may be superficially about finding the perfect Pinot Noir but I think brewers could replace that with the perfect lager/cask bitter/NEIPA. A great soundtrack as well, which deserves better than laptop speakers.
If you poke around Youtube there's lots of old footage of UK brewing.
