Kirkland Signature Olive Oil: Refined and 15% Extra Virgin Blend
- Refined + 15% extra virgin blend — a high smoke point and neutral base flavor with some extra virgin character mixed in
- Kosher certified (U) — certified by the Orthodox Union
- About 200 servings per bottle — 3 liters at roughly 15 mL per serving
- High smoke point — suited to pan frying, roasting, sautéing, and baking
- Mediterranean-sourced olives — blended from oil sourced across multiple growing regions for consistent flavor

How to Use
Use it for everyday pan frying, roasting vegetables, baking, building marinades, and mixing salad dressings. Store the bottle in a cool, dark pantry away from the stove; heat and light speed up flavor loss. Keep the cap tightly closed after opening and use within 12 to 18 months for the best flavor.

Frequently Asked Questions
Does Kirkland Signature Olive Oil contain allergens?
Kirkland Signature Olive Oil is made from olives and does not list common allergens such as milk, egg, tree nuts, peanuts, wheat, or soy on the label. Cross-contact during bottling can vary by production run, so anyone with a severe allergy should read the printed label on the bottle before using it.
How should I store Kirkland Signature Olive Oil, and how long does it last once opened?
Keep the bottle in a cool, dark pantry away from the stove and direct sunlight, since heat and light cause oil to lose flavor faster. Refrigeration isn't required and can cause the oil to cloud or thicken. Keep the cap sealed tightly between uses and aim to use the oil within 12 to 18 months of opening.
What is the difference between this blend and Kirkland's Organic Extra Virgin Olive Oil?
This bottle is 85% refined olive oil blended with 15% extra virgin, giving it a neutral flavor and a higher smoke point for everyday high-heat cooking. Kirkland's Organic Extra Virgin Olive Oil is 100% extra virgin with a stronger olive flavor, better suited to dressings and finishing than to sustained frying.
Where does Kirkland Signature Olive Oil come from, and what size does it come in?
The oil is blended from olives sourced across several Mediterranean growing regions to keep the flavor consistent year to year, then bottled and distributed by Costco Wholesale Corporation. It comes in one large 3-liter (101.4 fl oz) bottle, sized for households that cook with olive oil often rather than occasionally.
