Processing crops comes down to two main tools. The keg needs farming 8 to craft and handles fruits taking about 7 days for wine at 3x value, while vegetables become juice in 4 days at 2.25x value. Basic stuff like wheat to beer takes a day, hops need 1-2 days for pale ale, honey becomes mead in 10 hours, and coffee beans process in just 2 hours.

The preserves jar unlocks earlier at farming 4, and it's pretty straightforward. Fruits become jelly in 2-3 days selling for double base price plus 50g, while vegetables follow the same timing and formula for pickles. Good to know you can toss mushrooms and foraged items in there too.

For maximum profit, ancient fruit and starfruit are your best wine makers, while cheaper stuff like blueberries work better in jars. The rule of thumb is, use kegs for fruits worth more than 50g and vegetables above 200g, anything cheaper goes in jars. Once you've got wine, aging it in cellar casks doubles the value if you're patient enough. Corn and tomatoes are solid jar choices, and don't overlook those wild horseradish pickles for early game income.
