• I would imagine one spout pours faster than the other so you can get a little less using one side than the other. But I’ve never seen this myself so it’s just a guess.

    Or maybe because it’s entirely enclosed, one is so air can get in and it pours cleanly instead of bubbling out.

        Please don’t touch the spout on these in restaurants. If it’s your personal one, fine. But don’t do this to public ones please. Outside is dirty enough.

        How do you agree what side to modulate airflow? They look identical, and swapping sides to put your grubby fingers would be gross.

        Heh. It’s a idiot proof–okay maybe not completely–method to limit a pour. Prevents those idiot moments when you pour more than you wanted; like when you have a very nice–expensive bottle of Shoyu or Tamari.
