In “Stardew Valley Expanded”, there is a quest called “An Elegant Reception” given by Olivia. She wants to put on a reception in the town square and needs a bunch of fancy groceries to make it happen.
These include 10 starfruit wines, 10 cheese, and 10 goat cheese. The only requirement for the quest is that it not be winter. Delivering the items to her drop-off point in her wine cellar. Upon completion of the quest, Olivia will reward the player with 80000 Gold coins. Making it a very worthwhile investment of time and effort.
