Many tallboys and beer bottles have little ridges at the bottom to make them stable.
The ridges that circle the bottom helps prevent them from floating around when the bottle has a bunch of condensation making the bottle wet and slippery. If they did not have the bumps or ridges, the bottle could slide of your table.
As an example, cans do not have ridges, bumps or grooves and are obviously very light when empty. And many times, I have experienced my empty and sweaty can begin “floating” around the table with no help. I am no Jedi with abilities some would consider to be…unnatural.
I am just a dude telling explaining on YouTube what the ridges on the bottom of a bottle are:
So yeah, it’s what you thought, the little ridges on the bottom of a beer bottle help it to keep standing, no matter how sweaty it gets.
Plus, it’s fun to run your nails over them… wait, am I the only weirdo that does that?
