Olives 101: Nutrition, Benefits, How To Use, Buy, Store | Olives: A Complete Guide

What are Olives

Olives are small, oval-shaped fruits that grow on the olive tree (Olea europaea). They are a fundamental component of Mediterranean cuisine and are widely cultivated for their oil, known as olive oil. Olives have a distinctive taste, which can vary depending on factors such as their ripeness and the curing or processing methods used.

There are various varieties of olives, and they can be classified as green or black, but the color doesn’t necessarily indicate ripeness. Green olives are typically harvested before they fully ripen, while black olives are allowed to ripen on the tree. The color change is also influenced by the curing process, as fresh olives are naturally bitter and need to be processed to become palatable.

Olives are consumed in various forms, including:

1. Table Olives: These are varieties of olives that are typically brine-cured, water-cured, or dry-cured to make them suitable for direct consumption. Common types include Kalamata, Manzanilla, and Gaeta olives.

3. Oil-Cured Olives: These olives are cured in oil, often with herbs and spices, and have a wrinkled appearance. They are usually used as a flavorful addition to dishes.

Olives are rich in healthy monounsaturated fats and contain various nutrients such as vitamin E and antioxidants. They also contribute to the characteristic flavors of many dishes, adding a briny and savory taste.

8. Rich in Healthy Fats: Olives are a good source of monounsaturated fats and contain minimal saturated fats. Including healthy fats in the diet is essential for various bodily functions, including hormone production and nutrient absorption.

How To Store Olives

Proper storage is important to maintain the quality and freshness of olives. The storage method can vary depending on whether the olives are fresh, cured, or part of a prepared dish. Here are general guidelines for storing different types of olives:

1. Fresh Olives:
   • Refrigeration: Fresh olives, especially those that have not undergone curing processes, should be stored in the refrigerator. Place them in a sealed container or a resealable plastic bag.
   • Brine or Salt: If fresh olives are purchased in brine or salt, ensure they are fully submerged. Keep them in an airtight container in the refrigerator.
2. Cured Olives (Jarred or Canned):
   • Refrigeration: Once opened, store jarred or canned olives in the refrigerator. Transfer them to an airtight container if the original packaging is not resealable.
   • Brine or Oil: Ensure that the olives are fully covered in brine or oil to prevent them from drying out. This helps maintain their flavor and prevents spoilage.
3. Bulk or Olive Bar Olives:
   • Refrigeration: If you purchase olives from a bulk section or olive bar, transfer them to a sealed container and store in the refrigerator.
   • Brine or Oil: Keep them covered with brine or oil to maintain moisture and flavor. If olives are sold in oil, ensure they are fully submerged.
4. Prepared Dishes with Olives:
   • Refrigeration: If olives are part of a prepared dish, store the dish in the refrigerator. Cover it with plastic wrap or transfer it to an airtight container.
   • Separate Storage: If possible, store dishes with olives separately from other ingredients to prevent cross-flavoring.
5. Olive Oil:
   • Cool, Dark Place: Store olive oil in a cool, dark place away from heat and light. Exposure to light and heat can cause the oil to oxidize and lose its quality.
   • Airtight Container: Ensure that the olive oil container is tightly sealed to prevent air from entering, which can also lead to oxidation.
6. Homemade Olive Mixtures or Tapenade:
   • Refrigeration: Store homemade olive mixtures or tapenade in the refrigerator in an airtight container.
   • Olive Oil Layer: If the mixture contains olive oil, consider adding a thin layer of olive oil on top to create a barrier that helps preserve freshness.

Always check the product label for specific storage instructions, and follow any recommendations provided by the manufacturer. Proper storage helps prevent spoilage and maintains the flavor and quality of the olives for an extended period.
