3 Opinions for Kiddush Cup

thingiverse

On sacred Jewish holidays and special events, there is a rich tradition of sanctifying the occasion by reciting blessings over a glass of wine. However, many people wonder: how much wine is truly sufficient? A question that has been debated among scholars for centuries. Here are three distinct opinions on the minimum volume of wine required for such occasions, known in Hebrew as a revi'it or revi'is. Rav Chaim Naeh's opinion is clear: he asserts that 86-89 milliliters of wine are sufficient to warrant blessings. This opinion is based on his meticulous calculations and thorough research. The Chofetz Chayim, another prominent rabbi, takes a slightly different stance. In his view, no less than 112 milliliters of wine are necessary to justify reciting blessings over it. His reasoning is just as compelling as Rav Naeh's. Chazon Ish, however, has an even more generous interpretation. He believes that a minimum of 156 milliliters of wine is required to sanctify the occasion with blessings. His calculation is thorough and meticulous, based on careful measurements and verifications. Interestingly, these container volumes were calculated using Fusion 360 software, with the Boundary Fill option, and then verified via buret in PLA prints from a Makerbot Desktop 3D Printer.
