How to Bottle Extra Virgin Olive Oil: A Complete Guide for Artisan Producers

How to Bottle Extra Virgin Olive Oil

If you produce extra virgin olive oil in Andalusia—whether in a small family mill, a cooperative, or directly from your farm—knowing how to properly bottle your EVOO is just as important as the extraction process. Proper bottling protects the oil’s quality, complies with current regulations, and projects a professional image of your product.

In this guide, we explain step by step everything you need to know to bottle olive oil in an artisanal way: from choosing the ideal container to selecting the right closure, including the most important legal considerations in Spain and the European Union.

Why does the olive oil container matter so much?

Extra virgin olive oil is sensitive to three factors that accelerate oxidation: light, heat, and oxygen. The type of bottle you choose has a direct impact on the product’s shelf life and on the perception consumers will have of your brand.

• Ultraviolet light degrades polyphenols and accelerates oxidation. For this reason, dark or tinted bottles are preferable for long-term storage.
• Oxygen in the headspace of the container causes rancidity. High-quality airtight closures reduce this risk.
• Heat during transport can alter the oil’s sensory profile. A good container, properly sealed, minimizes this impact.

In short: investing in a good glass bottle is not an expense—it is real protection for your product and your reputation.

What type of bottle should you choose for bottling olive oil?

There are several options on the market depending on how the oil will be used and the profile of your end customer.

Dark or tinted glass bottles (green, amber)

These are the best option for high-quality EVOO that will be stored for several months. Tinted glass blocks between 60% and 90% of ultraviolet radiation, preserving the oil’s organoleptic properties. Very common in olive mills in Jaén, Córdoba, and Granada that want to protect products with PDO or PGI certification.

Clear glass bottles

They allow the golden or greenish color of the oil to be displayed, which is very attractive for direct sales at artisan markets, food fairs, or gourmet stores. Ideal for young oils intended for quick or seasonal consumption.

Most common formats and sizes

• 250 ml: gift or tasting format, ideal for premium single-variety oils.
• 500 ml: the best-selling format for household and hospitality use.
• 750 ml or 1 liter: suitable for regular customers and professional kitchen use.
• 5 liters (container): for restaurants, catering, and wholesale distribution.

Which cap should you use for olive oil?

The cap is just as important as the bottle. The most commonly used in the Andalusian artisan sector are:

Guala anti-drip cap: prevents spills and splashes when pouring. Highly valued in hospitality and the gourmet sector. Also available in PDO versions for oils with designation of origin.

Pilfer or aluminum cap: provides an airtight seal and a professional appearance. Ideal for first-opening security and ensures product integrity.

Natural cork stopper: adds an artisanal aesthetic value and is popular in limited-edition premium oils.

A common mistake is choosing the cap and bottle separately without checking the compatibility of the neck diameter. At The Pack Stock we offer bottles and caps with standardized measurements (TO28, TO31.5, Guala 31.5) so they always fit perfectly.

Steps to bottle olive oil correctly

1. Pre-filtering: make sure the oil is properly filtered and free of impurities before bottling. Organic particles accelerate fermentation.
2. Proper temperature: bottle at room temperature (between 18 and 22 °C). Avoid bottling oil that is too cold (viscous) or too hot (condensation risk).
3. Cleaning bottles: although new containers do not require sterilization, they must be dry and dust-free. In artisanal production it is common to rinse them with hot water and let them dry upside down.
4. Bubble-free filling: use a manual or gravity filler. Avoid shaking the oil and leave as little headspace as possible to reduce oxygen.
5. Immediate sealing: close the cap as soon as each bottle is filled. The less time the oil is exposed to air, the better.
6. Labeling: apply the label when the bottle is dry and completely free of moisture or oil residue. Use food-grade adhesive labels.

Basic regulations for packaging and selling olive oil in Spain

If your goal is to market the oil—not just for personal consumption—you must comply with labeling regulations established by EU Regulation 1169/2011 and specific olive oil regulations:

• Indication of the oil category (extra virgin, virgin, etc.)
• Sales denomination and net volume
• Best before date (not expiration date)
• Storage conditions
• Country of origin of the olives
• Batch number

For oils with PDO or PGI (such as Sierra de Segura Olive Oil, Baena Olive Oil, or Antequera Olive Oil), there are additional requirements for back labels and origin numbering.
