Why some CBD oils taste like grass, and others barely taste of anything
Open two CBD oils from different brands and the difference is immediate. One tastes grassy and vegetal, with a bitterness that lingers. The other is almost neutral, maybe a faint floral note, nothing unpleasant.
Three things drive that difference: the carrier oil, the extraction method, and whether terpenes were added back afterwards. The extraction method carries the most weight.
The carrier oil
CBD extract is thick and waxy on its own. It needs to be diluted in a carrier oil to become stable and easy to use. The choice of carrier oil has a direct impact on taste.
Hemp seed oil, cold-pressed from hemp seeds, has a distinct green, slightly nutty flavour that most people associate with the grassy taste of cheaper CBD oils. It is rich in omega fatty acids, but those polyunsaturated fats are also what make it unstable. Hemp seed oil goes rancid faster than MCT, which means a shorter shelf life and a taste that keeps shifting in the bottle.
Olive oil is used as a carrier in some products, particularly simpler formulations. It has its own flavour profile and a lower saturated fat content, which makes the oil thicker and harder to dose consistently.
MCT oil, usually derived from coconut, is almost tasteless and chemically stable. It is rich in saturated fatty acids, making it far more resistant to oxidation and rancidity than hemp seed oil. That stability shows up in shelf life: an MCT-based oil holds its flavour profile longer. It also mixes easily with fat-soluble compounds and gives a thin, consistent texture.
Extraction method matters more than most people realise
Hemp contains hundreds of compounds beyond CBD: terpenes, flavonoids, chlorophyll, waxes. The extraction method determines what ends up in the finished product.
Ethanol extraction is the most common method in the industry because it is cheap and scalable. The problem is that alcohol is not selective. It pulls most things out of the plant, including chlorophyll, which is responsible for the green, grassy taste. Chlorophyll can be filtered out afterwards, but the process is inconsistent and quality varies between producers. There is also the question of solvent removal: how thoroughly has the ethanol been stripped out? Residual ethanol in finished products is common when producers have not invested in adequate post-processing.
CO2 extraction is more technically demanding and more expensive, but produces a fundamentally different result. Pressurised carbon dioxide is selective in a way that ethanol never is. It pulls out cannabinoids and terpenes without dragging along chlorophyll and plant matter. The extract is cleaner from the start, lighter in colour, and without the grassy edge. When the process is complete, the CO2 disappears entirely. It is a gas, not a solvent that needs to be cleaned away. There is nothing left behind.
Terpenes: what makes the difference between flat and alive
Terpenes are the aromatic compounds in hemp responsible for everything from citrus and floral notes to earthy and woody ones. In a full spectrum oil they are preserved naturally through extraction, but their survival depends on how carefully the process was handled. They are fragile enough to break down under heat.
In a broad spectrum extract, THC is removed in an additional refinement step and some of the natural terpenes are lost in the process. Adding terpenes back in afterwards gives control over the final profile. Specific terpenes can be chosen to complement the oil without carrying the grassy character of a chlorophyll-heavy raw extract.
The difference is between having whatever survived the extraction process and actively choosing which aromatic compounds contribute to the entourage effect.
What the taste tells you
Grassy, green and slightly sharp: ethanol extraction, probably with hemp seed oil as the carrier, possibly with chlorophyll remaining in the extract. It is the most common combination on the market and the cheapest to produce.
Neutral or subtle with a faint floral note: CO2 extraction, MCT carrier, controlled terpene content. No oil tastes neutral by accident. It takes better raw materials and a more expensive process.
A sharp, slightly chemical taste that recalls solvent is a warning sign and points to inadequate post-processing of an ethanol extract. It should not be present in a finished product.
How we work
We use CO2 extraction and MCT oil. CO2 gives a clean extract without chlorophyll and without solvent residues. MCT has a longer shelf life and does not affect the flavour profile. We then add natural terpenes back to preserve the entourage effect.
The result is an oil with a neutral, slightly floral taste. No grassy edge, no residual ethanol.

Frequently asked questions
Why does my CBD oil taste like grass?
Most likely the extract was made with ethanol, which pulls chlorophyll out of the hemp plant, and/or hemp seed oil is used as the carrier. Hemp seed oil has a naturally green, nutty flavour. There is nothing wrong with the product, but it is a direct result of the production method.
Does a neutral-tasting CBD oil have less CBD?
No. Taste has no bearing on strength. A neutral oil can have exactly the same CBD concentration as a grassier one. The difference is in extraction method and carrier oil choice, not potency.
What is MCT oil?
MCT stands for medium-chain triglycerides and is usually derived from coconut. It is a thin, nearly tasteless oil that mixes well with fat-soluble compounds. It is widely used in food production and as a neutral carrier in cosmetics and supplements.
Does the taste change over time?
Terpenes are volatile and can fade gradually, especially if the oil is stored somewhere warm or in direct light. Keep it cool and dark, and use it within the stated shelf life.
