Homemade rosemary oil, when properly prepared and stored, can last for up to 1 year.
To ensure your homemade rosemary oil lasts that long, consider the following:
- Preparation: Use fresh, clean rosemary and high-quality olive oil (or another carrier oil). Ensure your tools and containers are sterilized to prevent contamination.
- Storage: Store the oil in a sterilized glass jar in a cool, dark place. Exposure to light and heat can degrade the oil and shorten its shelf life.
- Straining: After infusing the oil with rosemary, strain it thoroughly to remove any plant matter. This prevents spoilage and extends the oil's lifespan. A fine-mesh strainer or cheesecloth works well.
- Signs of Spoilage: If the oil develops an off odor, changes color, or shows signs of mold growth, discard it immediately.
By following these steps, you can enjoy your homemade rosemary oil for up to a year.
