Making a profit in "Stardew Valley" takes a lot of planning and choosing the right products to make. Thanks to the new update, the maximum upgrade of the house now have an added cellar, which contains 33 casks. However, players can add casks through crafting it with hardwood. The main function of these casks is to age cheese and wine. In reality, aged cheese and wine tastes better, has better quality, and costs more. That is the reason why in this successor of "Harvest Moon," ageing makes cheese and wine into an Iridium quality, the highest quality in "Stardew Valley."

Ever increasing gold each day

When a wine or cheese is put inside the cask, its value increases per day and it depends on how many days, it takes to become Iridium quality goods in "Stardew Valley." These quality goods increase income, which is good for players. In addition, truffle oil can be aged as well. Based on this discussion from Steam community, Ancient fruit wine, cheese, and truffle oil can be aged in the casks. As much as possible, it is efficient to fill up every gap and space, considering that players can still go in and out of the cellar, to maximise profit.

Goat cheese is the way to go

Gather more goat milk and create numerous cheese makers to create goat cheese. Goat cheese cost a lot and making them into Iridium quality can profit players up to 700 K gold. The bond between goats also contributes to the quality. Since it is already gold quality as mentioned by Hawlucha on the Steam community page, it only takes a week or more to make the Iridium quality goat cheese using the casks in the cellar. Profits will be coming through and this is one of the ways to gain faster money. It is worth investing in a maximum upgrade indeed in "Stardew Valley."
