A Home Cook’s Guide to Buying Olive Oil in the UK

Navigating the olive oil aisle can feel surprisingly complex. With labels boasting terms like "cold pressed," "extra virgin" and various country origins, it's easy to grab a bottle that looks the part but doesn't suit your cooking needs. Many UK households end up with an expensive finishing oil that smokes on the hob, or a flavourless one that falls flat in a salad dressing. The goal is to find the right oil for the right job, without falling for marketing hype.

As the Joybuy Product Recommendation Officer, my role is to help you understand the practical differences so you can make a confident choice. Let's look at the common pitfalls and what really matters when you buy olive oil.

The 3 Traps to Avoid When Buying Olive Oil

1. Using the Wrong Oil for the Heat: A frequent mistake is using a delicate, expensive extra virgin olive oil for high-heat frying. This not only burns the oil, creating an unpleasant taste and smoke, but it also destroys the very flavour compounds you paid a premium for. Conversely, using a standard refined olive oil for a delicate salad dressing will lack the fruity, peppery notes that make the dish special.
2. Falling for Fancy Bottles Over Function: A clear glass bottle might look appealing on the shelf, but light is one of olive oil's biggest enemies. Prolonged exposure to light and heat degrades the oil, causing it to lose its flavour and nutritional properties much faster. A pretty label on a clear bottle often hides a product that won't stay fresh for long once you get it home.
3. Misinterpreting "Light" Olive Oil: The term "light" on an olive oil label does not refer to its calorie or fat content. All olive oils have a similar calorie count. "Light" or "Extra Light" simply refers to a lighter colour and a more neutral flavour, achieved through heavy refining. It's suitable for baking or frying where you don't want any olive taste, but it's a mistake to buy it thinking it's a healthier, lower-fat option.

Core Factors to Check Before You Buy

To ensure you get the right product for your kitchen, focus on these key parameters. Understanding them will help you select the perfect olive oil for cooking, salads or finishing.

1. The Grade: Extra Virgin vs. Standard Olive Oil

This is the most important distinction. The grade tells you how the oil was processed and what it's best used for.

• Extra Virgin Olive Oil (EVOO): This is the highest grade. It is an unrefined oil extracted solely through mechanical means, usually a cold pressed method, without the use of chemicals or high heat. This process preserves the natural flavour, aroma and antioxidants from the olives. EVOO has a lower acidity level (below 0.8%) and a more pronounced fruity or peppery taste. It's the ideal choice for use as a dressing, for dipping bread or for drizzling over finished dishes. While you can cook with it at lower temperatures, its delicate flavours are best appreciated raw. Many high-quality Italian olive oil and organic olive oil options fall into this category.
• Standard Olive Oil: Often simply labelled "Olive Oil," this is a blend of refined olive oil and a smaller amount of virgin or extra virgin olive oil. The refining process makes the oil more stable at higher temperatures and gives it a milder, more neutral flavour. This makes it a versatile, all-purpose olive oil for cooking, including sautéing, roasting and even light frying.

2. Smoke Point

The smoke point is the temperature at which an oil begins to break down and produce visible smoke. Using an oil above its smoke point can ruin the flavour of your food and release harmful compounds.

• Lower Smoke Point (approx. 190°C): Typical for extra virgin olive oil. This makes it suitable for gentle sautéing but not ideal for deep-frying or searing at very high heat.
• Higher Smoke Point (approx. 210°C - 240°C): Found in standard or refined "Olive Oil." This stability makes it a reliable workhorse for everyday cooking methods that require more heat.

3. Packaging and Size

Always opt for olive oil packaged in dark glass bottles or opaque tins. This protects the oil from light degradation. For size, consider your usage. If you use olive oil daily, a 1l olive oil bottle or even a larger tin can offer better value. If you only use it occasionally for dressings, a smaller 250ml or 500ml bottle ensures you finish it while it's still fresh.

Frequently Asked Questions

1. Can you cook with extra virgin olive oil?

Yes, you can, but it's best for low-to-medium heat cooking like sautéing or baking. Its smoke point is lower than refined oils, so it's not the right choice for deep-frying or searing at very high temperatures. To get the most value from its superior flavour, it's often best to add it at the end of cooking or use it raw.

2. How should I store olive oil to keep it fresh?

The three enemies of olive oil are heat, light and air. Store your bottle or tin in a cool, dark place like a cupboard, away from the oven or hob. Always make sure the cap is screwed on tightly after use to minimise exposure to oxygen. There is no need to refrigerate it; in fact, this can cause it to solidify and may trap condensation in the bottle.

3. What does "cold pressed" actually mean?

"Cold pressed" (or cold extraction) means the oil was extracted from the olives using only mechanical pressure, without any added heat. The temperature is kept below 27°C during the process. This gentle method helps the oil retain its full flavour, aroma and nutritional profile, and it is a hallmark of all extra virgin olive oils.
