As for the shelf life of the infused oil, Annette says that depends on what type of ingredients you place in the bottle. Its good for about six months, although Ive had some infused oils for over a year. If you use fresh fruit in the bottle, like kumquats or olives, after a while the mixture may get a little cloudy.

Also, do I need to refrigerate infused olive oil? Refrigerate your infused oils and keep them only for a few days. (Note, most olive oils will solidify slightly in the refrigerator. Bring the infused oil to room temperature before drizzling onto cold foods. )

Accordingly, how long can you keep garlic infused olive oil?

It can keep in the fridge for at least 2 to 3 weeks. If you wish to keep a small portion of the garlic oil on the counter for cooking on a regular basis, feel free to do so. However, infused oils are more delicate and will keep better if stored in a cool place away from direct light and heat.

How long will rosemary last in olive oil?

Turn off the heat and let the rosemary infuse in the oil for 1 hour. Strain into a clean, dry glass bottle or jar (it is not necessary to sterilize the bottle or jar for this recipe). Cover tightly and store away from direct light or heat at room temperature for up to 2 months, or in the refrigerator for 6 months.
