It’s not easy to come by the right small wine glasses for Seder night.
From the minimum requirement of 2.9 ounces to fulfill a “Reviis” to the machmir amount of 5.1 ounces, everyone holds differently.
The Chazon Ish says to drink 150 ml = 5.07 oz. The most accepted opinion for this (R. Chaim Noeh) is 86 ml, which is a bit over 2.9 oz. Some people on Friday night are machmir to do 4.2 ounces. Of course, as always, ask your own LOR.
That being said, no matter how much you drink, it’s still hard to find the right small-sized glasses. We’ve found a nice amount and rounded them up for you here!
