Olive Oil Buying Guide: Choose the Right Bottle for Cooking, Dressing and Dipping

Choosing olive oil in the UK is not simply a matter of picking the largest bottle or the most attractive label. The terms extra virgin olive oil, “cold-pressed”, “Italian” and “light” describe different qualities, origins or uses. Selecting the wrong type can leave you with an oil that is too strongly flavoured for delicate dishes, inconvenient to pour or poor value for occasional use.

This guide explains the practical details to check before buying olive oil, from product category and bottle size to storage, cooking suitability and format.

Common Olive Oil Buying Pitfalls

1. Confusing “light” with lower-calorie oil

Mild and light olive oil usually refers to lighter flavour and colour, not a substantially lower calorie content. Filippo Berio Mild & Light Oil, for example, contains refined olive oil and virgin olive oil. Its subtle aroma is designed for frying, sautéing and baking, but it is still an oil with a high energy content typical of cooking oils.

If you want to control how much oil reaches the pan, a spray or precision squeeze bottle may be more useful than choosing a product labelled “light”.

2. Assuming every extra virgin olive oil tastes the same

Extra virgin olive oil is a defined category obtained directly from olives using mechanical methods. However, flavour varies according to olive variety, growing region, harvest conditions and blending.

A mild Tunisian oil may suit everyday cooking without overpowering ingredients, while a Greek Kalamata PDO oil can have grassy, herbaceous and peppery notes that are more noticeable in salads, dipping and finishing. Read the flavour description rather than relying on the category name alone.

3. Buying bulk olive oil without a storage plan

A 1 litre, 2 litre or 5 litre container can offer convenience for families, restaurants and caterers, but olive oil gradually loses freshness after opening when exposed to air, light and heat. A large bottle is only practical if you use it regularly and can store it in a cool, dark cupboard.

For occasional cooks, 500ml olive oil or 250ml may protect flavour and reduce the risk of keeping an opened bottle for too long.

Core Specifications to Check Before Buying

Olive oil category and intended use

• Extra virgin olive oil: Suitable for salads, dipping, marinades, drizzling and finishing. It can also be used for cooking, but delicate, fruity or peppery flavours may be less noticeable after prolonged heating.
• Virgin or blended olive oil: Check the ingredient list carefully. Refined and virgin olive oil blends often have a milder taste and are useful as cooking olive oil.
• Olive pomace oil: Extracted from olive residues and commonly blended with another oil, such as rapeseed oil. KTC Olive Pomace Oil Blend contains 52% olive pomace oil and 48% rapeseed oil, with an anti-foaming agent. It is positioned for frying, baking and high-volume kitchen use rather than bread dipping.

The phrase cold-pressed olive oil is commonly used to indicate extraction without significant heat. Nevertheless, the full product description and ingredients should remain your reference, especially where origin and flavour matter.

Origin, flavour and certification

Italian olive oil may be blended or sourced from a particular region, so check whether the label states a specific country, region or blend. Products such as Tuscan or Puglian oils can offer distinctive flavour descriptions.

Greek olive oil with PDO status identifies a protected geographical origin and production conditions. Odysea PDO Kalamata Extra Virgin Olive Oil is made from Koroneiki olives grown and pressed in the Kalamata region. Its listed profile includes medium fruitiness, herbaceous flavour and a peppery finish, making it more suitable for olive oil for salads, dipping and drizzling than for neutral baking.

Bottle format and size

Choose the format according to how you cook:

• Squeeze bottles: Useful for olive oil for salads, marinades and controlled finishing.
• Olive oil spray: Practical for coating pans, baking trays or air-fryer ingredients with a fine mist. Check the safety instructions and never spray near a naked flame or directly onto a very hot surface.
• Dark glass: Helps limit exposure to light and can suit premium oils intended for finishing.
• 500ml bottles: A manageable option for most households.
• 1 litre olive oil and larger sizes: More appropriate for frequent cooks, restaurants, caterers or larger families.

Store olive oil at room temperature, away from direct sunlight and heat. Cloudiness below approximately 7–10°C can occur naturally and does not necessarily indicate spoilage. Do not refrigerate unless the packaging specifically instructs you to do so.

Frequently Asked Questions

Is extra virgin olive oil suitable for frying?

Extra virgin olive oil can be used in hot cooking, but suitability depends on the recipe, heat level and product guidance. For high-temperature or neutral-flavour cooking, a mild olive oil, olive pomace oil blend or another cooking oil may be more practical. Avoid heating any oil until it smokes.

How should olive oil be stored after opening?

Keep the bottle tightly closed in a cool, dark cupboard away from the hob, oven and direct sunlight. Avoid leaving oil beside a hot cooker. A smaller bottle may be more suitable if you use olive oil slowly.

Is a spray or squeeze bottle more economical?

It depends on your cooking habits. An olive oil spray can help distribute a fine coating across a pan or tray, while an olive oil squeeze bottle provides control for salads, dipping and finishing. Compare the quantity, ingredients and intended use rather than assuming either format automatically costs less.
