The shelf life of Buža olive oil, like other olive oils, depends on proper storage. When stored in a cool, dark place away from heat, light, and air, unopened Buža olive oil can retain its quality for up to 2 years or more. Once you open a bottle of Buža olive oil, its shelf life is generally shorter. It is best to consume it within 3 to 6 months to enjoy its peak flavour and aroma.
