> The reason it is so popular is because most beer sold in Brazil comes in 600 ml bottles to be shared by everyone at the table.
Hum... I'm not sure.
I believe the reason it is so popular is that it is cheap and widely distributed.
But also, none of the other solutions on the article are good enough to support large temperature differences. What matches very well with it being the "daily" glass, while tulips are more refined, "nightly" ones.
Oh, and it also has a viable size for coffee, water, and cahcaça (where usually only the bottom is filled).
There is also a smaller version of the tulip that is popular South of São Paulo, where other companies got more reach than Nadir Figuereido.
