Learn how to use the Everyday Refill Kit from Kosterina to refill your EVOO bottles, reduce single-use packaging, and save money with a sustainable olive oil refill system.
Quick answer
Use the Everyday Refill Kit to refill your empty EVOO bottles directly from the 3-liter tin, cutting down on single-use glass and plastic while saving money per ounce.
Why the Refill Kit reduces waste better than buying new bottles
Every time you buy a new bottle of olive oil, you add to the manufacturing and shipping footprint of glass or plastic. The Everyday Refill Kit replaces six standard 500ml bottles with one reusable 3-liter tin, slashing packaging waste by roughly 80% over the life of the tin. Because the tin is recyclable and the included funnel lets you refill any bottle you already own, you stop generating new bottle waste with each purchase.
The trade-off is that the tin is heavy (about 6.6 pounds full) and requires some counter or pantry space. If you have limited storage or prefer single-serving sizes for travel, the kit may feel bulky. But for regular home cooks who go through oil quickly, the space savings and waste reduction easily outweigh the initial size.
How the kit saves you money while being eco-friendly
The Everyday Refill Kit costs USD 75.52 compared to a catalog comparison price of USD 118.00 for the equivalent volume in individual bottles. That is a 36% savings per ounce. Over several refills, the kit pays for itself while keeping dozens of bottles out of the waste stream.
One limitation: the kit is designed for the Organic Everyday Extra Virgin Olive Oil only. If you prefer flavored or specialty oils, you would need separate containers. But for daily cooking, baking, and dressing, this single oil covers most needs.
Step-by-step: Refill your EVOO bottle with the Everyday Refill Kit
- Prepare your empty bottle and funnel: Wash and dry a clean, empty olive oil bottle (or any narrow-neck bottle you want to reuse). Insert the included funnel firmly into the bottle opening. A common mistake is using a bottle with residual moisture—water can degrade olive oil quality. Make sure the bottle is bone-dry.
- Open the 3-liter tin: Peel back the metal tab on the tin lid slowly to avoid splashing. If the lid is tight, use a flathead screwdriver to gently pry it open. Do not shake the tin before opening. Check that the pour spout under the lid is clear of any plastic or foil debris before pouring.
- Pour oil into the bottle: Hold the tin with both hands (it is heavy) and tilt it steadily over the funnel. Pour until the bottle is about 80% full—leave headspace for the cap and to avoid spills when closing. Do not overfill: oil expands slightly in warm kitchens, and a full bottle can leak when you screw on the cap.
- Cap the bottle and store the tin properly: Remove the funnel, wipe any drips from the bottle neck, and screw the cap on tightly. Place the tin in a cool, dark pantry (not near the stove or in direct sunlight). Store the tin upright to prevent leaks. If you do not plan to refill again soon, seal the tin with plastic wrap under the lid to keep out air.
- Repeat as needed: When the bottle is empty, wash it, dry it, and repeat the process. The tin holds enough oil for about six full refills of a standard 500ml bottle. Write the date you opened the tin on the label with a marker. Olive oil stays fresh for about 12 months from opening if stored correctly.
Product facts
- The Everyday Refill Kit: Each 3-liter tin of Organic Everyday Extra Virgin Olive Oil is the equivalent of 6 bottles, for a long-lasting supply of EVOO you can count on. Each kit includes a complimentary funnel, so you can refill your bottles with ease. You avoid buying six separate glass bottles, which reduces manufacturing emissions and shipping weight, and the included funnel makes refilling mess-free.
