Now I wonder - what is a 'beverage sipper', and how is it different from a 'glass' or 'cup'?
The porron is supposed to be for communal drinking without touching lips to a shared vessel. Although as far as I've been able to tell is used as much for drunk people to get wine all over their shirts.
The port sippers seem to me personally to be... a little more childish? Clearly it's just my cultural associations, but I feel like drinking through a straw is like drinking from a sippy cup.
