Resistance is Futile, We Have Homebrew!

There's a museum brewery about a mile and a half from my house, brewing as they did in the mid-1800's. Many of the brews are indeed sours. I recently had a sour porter that was kinda weird but delicious. The first lager produced in the area was in 1852.mashani wrote:What that article totally misses however, is that the long term storage - the laagering as such - was not simply about the clarity/etc... but about the discovery that *it doesn't fooking get sour like ale!*
Because sour bugs do not work at those temperatures.
Beer got sour back then. A lot. Except for very strong and/or intentionally sour/aged/blended beer and/or stupendously hopped beer (like 200 IBUs of hops actually all use in bittering) ales were pretty much consumed within a week or weeks of manufacture.
So when we talk about "clean" tasting beer, that is a major factor.
The clarity is just a nice side effect that we like a lot today because we have sanitation.
