The grapes are part of the culture. When midnight comes around, you’re supposed to eat one grape for each “bong” and make a wish. That’s a lot of grape eating in a very short period of time, thus the list lol. I don’t know about ERC but they provide you with a cute little package of grapes at EPM

Hi Cathryn! we do this also in ERC 12 grapes- 12 wishes!!! see you soon
