Expiration & Storage Tips
When does grapeseed oil expire?
Unopened, grapeseed oil can last up to two years if stored properly, away from light and heat. Once opened, it's best to use it within six months. While you can extend its shelf life slightly by keeping it in the fridge, it doesn't freeze well and this can affect its texture and viscosity.
How do you tell if grapeseed oil is bad?
Grapeseed oil that's past its prime typically has a rancid, bitter smell and taste. If you notice a strong or off-putting odor when you open the bottle, or if the oil has a strange flavor, it's likely gone bad and should be discarded. Color changes can also indicate spoilage, such as if the oil becomes cloudy or has a darker appearance.
Tips for storing grapeseed oil to extend shelf life
• Store grapeseed oil in a cool, dark place, such as a pantry or cupboard, far from the stove or other heat sources.
• Consider transferring the oil to a dark glass bottle if it came in a clear one to protect it from light exposure which can lead to rancidity.
• While refrigerating grapeseed oil can extend its shelf life, remember to allow it to return to room temperature before using it for cooking as it thickens in colder temperatures.
• Always remember to tightly close the cap after each use to prevent exposure to air which accelerates oxidation and spoilage.
