The most famous triangle in brewing didn't disappear by accident. It disappeared by memo.
Then
On every good bar.
For generations, that red triangle sat behind bars from Boston to San Francisco. It was the black-and-tan standard, the "safe bet" pale ale, the one your grandfather ordered without looking at the menu. William Bass started brewing it — officially, Bass Pale Ale — in Burton upon Trent in 1777, and in 1876 the triangle became the first trademark ever registered in the United Kingdom — Trademark No. 1, ahead of every brand that came after it.
Now
Nowhere at all.
In the early 2020s, AB InBev — the brewing giant that owns Bass today — quietly stopped shipping it to the United States. No farewell tour, no announcement, just distributors running out and never restocking. Bars serving it out until the keg ran dry, then switching the tap handle for good. It's still poured in the UK. It just isn't poured here.
