Have a look at the following picture and tell me 1) what's wrong with this pour, and 2) what's right with it?
This is, in a nutshell, why the Honest Pint Project exists. The wrongness of it is clear by visual inspection, yes? It's the Herve Villechaize of pours (that means "short" to those of you too young to have enjoyed the high art spectacle of Fantasy Island back in the 80s). It is in fact a rather succulent cask XPA enjoyed earlier today at Deschutes (a certain beeronomist is racing to capture the picture in the background to offer a competing, erudite post on the lessons of symmetric information). The rightness? Because this is an honest pint, you know exactly how short the pour is. Because we know what the size of the serving vessel is, we can make adjustments accordingly.
Your options: 1) order a regular tap, 2) stiff the waitress, 3) blog about the injustice later.But because the pint glass is honest, you have the opportunity to adjust your behavior accordingly.
