What are natural preservatives for drinks?

Natural preservatives for drinks include ingredients like citric acid, found in citrus fruits, which helps inhibit microbial growth and maintain acidity. Other options are honey, which has antimicrobial properties, and certain essential oils like rosemary or thyme, known for their antioxidant effects. Additionally, vinegar, particularly Apple cider vinegar, can act as a preservative due to its acetic acid content. These natural alternatives can help extend shelf life while enhancing flavor.
