The colour of CBD oil: why are some oils darker than others?

The colour of CBD oil is a mystery to many people. Why are some oils darker than others? What factors influence the colour of CBD oil?

In this blog post, we will answer these questions and explain the different factors that influence the colour of CBD oil. We will also explain why some oils are darker than others and what this means for your health.

Does the colour of CBD oil matter?

To put it simply - yes. The colour of CBD oil can provide valuable information about its quality and composition. Depending on how it has been processed, extracted, and refined, the colour of CBD oil may range from a dark green or amber hue to a light yellow or even clear. These variations usually reflect differences in purity, potency, chemical composition, and overall quality.

The green or amber hues often indicate that the CBD was extracted using CO2 extraction methods, which are considered to be the cleanest and most efficient techniques for producing high-quality CBD oil. On the other hand, lighter shades such as yellow or clear can mean that additional refining processes were performed after extraction; these processes may have removed certain beneficial compounds like terpenes from the product in order to increase its shelf life or make it odourless.

In general, golden or brown colours are associated with higher concentrations of cannabidiol (CBD) and other beneficial compounds present in hemp extract. While this doesn’t necessarily guarantee product quality—a light-coloured CBD oil could also yield good results—it’s important to note that some processing techniques used to achieve lighter colours may lead to a decrease in potency. Therefore, if you’re looking for particularly potent extracts you should opt for golden-coloured products whenever possible.

Why does CBD oil change colour?

CBD oil can adopt a range of colours; from light yellow to dark brown and everything in between. The colour of the oil can change depending on a few factors; the type of CBD extract, the extraction method used and the amount of time the oil is exposed to air.

Extraction method: The extraction method used can also affect the colour of the CBD oil. For example, oils extracted with CO₂ are usually lighter than those extracted with ethanol.

Exposure to air: The time the oil is exposed to air can also affect its colour. Oils that are exposed to air for a longer period of time can darken.

What colour should your CBD oil be?

The colour of your CBD oil can vary and it is not always possible to accurately determine the colour of the oil pre-production. However, most oils should be light yellow or golden. Oils that are darker may be less potent or of a lower quality.

Why has my CBD oil turned pink?

The pink hue in CBD oil signifies the presence of a single compound: polyphenol oxidase. This compound turns pink when exposed to oxygen and light. This process mostly occurs in transparent tinctures. Since all of Nordic Oil’s oils are a golden colour, this phenomenon has never been observed or reported by our customers. Nonetheless, it is good to know that Polyphenol oxidase is present in hemp and various plant materials, including common fruits.

Why has my CBD oil turned brown?

The brown or even black colour of CBD oil results from similar chemical reactions. Initially, these oils have an earthier tone, and the colour change isn't as drastic. Exposure to oxygen, light, heat, and natural ageing can cause the tincture's plant components to darken quickly.

How does filtration affect the colour of CBD Oil

Filtration plays a big role in the colour of CBD oil. The plant material used to make the oil can affect the colour, as can the extraction method. Some oils are darker because they are less filtered, while others are lighter because they contain less plant material.

Raw hemp oil, for example, is dark green in colour because it is not filtered at all. This oil is extracted from the plant material directly by pressing or crushing, and the resulting oil contains all of the plant's terpenes, including chlorophyll.

Filtration also determines whether the taste is milder or more bitter; oils with better filtration have an earthy, mild flavour, whilst darker, less filtered oils tend to taste bitter.

Do carrier oils influence the colour of the CBD oil?

Carrier oils can indeed influence the colour of CBD oil. Cold-pressed hemp seed oil, which is light green, serves as an example. When combined with the brown CBD extract, it results in a golden hue. Similarly, when CBD oil is mixed with MCT oil, the resulting blend has an even lighter colour. The choice of carrier oil not only affects the appearance but also the taste, texture, and bioavailability of the final product. Therefore, it's essential to consider the type of carrier oil used in your CBD oil, as it plays a significant role in the overall experience and effectiveness.

Does the colour of my CBD oil influence my overall health?

In general, both darker and lighter oils contain CBD, so theoretically they should both have the same effect. That said, a darker oil contains much more plant material, which not only affects the taste, but it can also be harder for the body to absorb the cannabinoids. Darker oils can also be more likely to cause stomach upset in some people. So often, it can be a process of testing which works best for you.

How can you tell if CBD oil is high quality?

Determining the quality of CBD oil involves examining several factors. First, look for third-party lab testing results, ensuring the product's purity, potency, and absence of contaminants. Next, consider the source of hemp, as reputable brands use high-quality, organically grown plants. The extraction method also plays a crucial role; CO2 extraction is preferred for its safety and efficiency. High-quality CBD oil should have a clear or golden hue, though full-spectrum oils may appear cloudy due to additional beneficial compounds. Lastly, research the brand's reputation and customer reviews to gain insight into the product's effectiveness and overall quality.

Storing CBD oil to avoid colour change

To maximize the shelf life of your CBD oil, adhere to these optimal practices: Ensure your oil is securely sealed in its original container to reduce air exposure. Place your CBD oil in a cool, dark location, avoiding direct sunlight or artificial light. Prevent temperature variations by maintaining your oil at room temperature and distant from extreme heat or cold. Store your oil in a dry setting with minimal humidity to deter mould or other contaminants from forming.
