How long can you leave olives in water?

Olives can be soaked in water for anywhere from a few hours to several days, depending on the desired flavor and saltiness. Typically, soaking them for 1 to 3 days can help reduce their bitterness and saltiness effectively. It's important to change the water daily to maintain freshness and prevent spoilage. However, if you prefer a stronger flavor, you can soak them for a shorter time.
