Cold-pressed CBD oil: just a marketing gimmick or a real difference in quality?

Cold-Pressed CBD Oil: What Exactly Does It Mean?

Cold pressing refers to a mechanical extraction method used to obtain oil from seeds, fruits or nuts. It is an ancient technique, likely several thousand years old. The Romans were already using it to produce their oils, as shown by the remains of presses found in Tunisia and Morocco.

Here’s how it works today with our partners:

• After harvesting, olives, coconuts or flax seeds arrive at the oil mill;
• They are first sorted to remove impurities, then washed with water;
• Once dried, they pass through a screw press—a large machine that looks like a giant grinder. The screw rotates slowly and compresses the seeds against a metal chamber;
• Under mechanical pressure, the oil is released and drips through small openings.

Throughout the entire process, the temperature never exceeds 60°C—just enough to make the oil more fluid without cooking it. What remains in the press is the seed cake (the dry fibrous residue), which is reused to feed cows, chickens and horses.

Freshly extracted oil is still cloudy. It is filtered to remove suspended plant particles, then bottled immediately. No extra heating to clarify it, no chemical treatment to deodorize it, and no artificial preservation.

Cold Pressing vs. Other Extraction Methods

Cold pressing stands in opposition to industrial extraction techniques focused on speed and yield rather than preserving the oil’s nutritional qualities.

Hot Extraction

The raw material is heated between 80°C and 200°C. Heat breaks down the plant structure, which allows more oil to be extracted in less time (up to 30% more oil compared to cold pressing).

But this heat destroys part of the vitamins, antioxidants and fatty acids. The resulting oil may look clearer and more stable, but it is nutritionally depleted.

Solvent Extraction

This technique dissolves the oil contained in seeds or fruits using chemical solvents, typically hexane or ethanol. The crushed material is mixed with the solvent, which absorbs the oil… then the mixture is heated to evaporate the solvent.

The yield is excellent; the costs are low… but solvent residues may remain in the final oil. As with hot extraction, high temperatures degrade beneficial active compounds.

CBD Oil: What Are the Benefits of Cold Pressing?

Cold pressing preserves beneficial compounds, avoids chemical residues, and reduces environmental impact.

1. The Oil Retains Its Vitamins and Omegas

Hot extraction destroys vitamins—especially vitamin E, a powerful antioxidant—and breaks omega-3 and omega-6 fatty acids. The oil becomes almost nutritionally useless.

Cold pressing (below 60°C) keeps vitamins and omegas intact. The bottle contains all the goodness of olives, coconuts or flax seeds: vitamin E, essential fatty acids, polyphenols (natural anti-inflammatories), lauric acid (antibacterial/antiviral) and alpha-linolenic acid (cholesterol regulation).

2. No Chemical Residues

Solvent extraction leaves small traces of hexane or ethanol.

Cold pressing uses no chemicals: just a screw applying pressure. What comes out of the press is pure oil.

3. More Environmentally Friendly

Industrial extraction consumes energy for heating, uses solvents that must be produced and treated, and generates chemical waste. Refineries run for hours at high temperatures, increasing carbon footprint.

Cold pressing uses no high heat, no solvents, and produces minimal waste. The leftover seed cake is reused as animal feed.

4. A More Natural Taste (Not for Everyone)

Cold-pressed oil retains the natural aromas of its source. Olive oil tastes fruity or peppery; flaxseed oil has nutty notes. These flavors remain in your CBD oil.
Some enjoy this because it softens or masks hemp’s earthy bitterness; others don’t.

CBD Oil: What Are the Drawbacks of Cold Pressing?

Cold pressing guarantees nutrient-rich oil, but these nutrients are fragile.

1. Much Shorter Shelf Life

Cold-pressed oils keep for 6 to 12 months. After that, essential fatty acids oxidize and the oil becomes rancid.

Its color darkens, the smell intensifies and the taste becomes bitter. Cannabinoids lose potency, even if the oil is still consumable.

In contrast, oils extracted via heat or solvents last 2 years or more thanks to refining.

2. Stricter Storage Conditions

Cold-pressed oils are sensitive to heat, light and humidity. They must be stored in a closed cupboard, away from sunlight, between 15°C and 23°C.
The bottle must remain sealed; oxygen accelerates degradation.

Refined oils tolerate environmental changes far better.

3. Cold-Pressed Oil Costs More

Yield is low: large quantities of raw material are needed for a small amount of oil. Presses operate slowly. Manufacturers must store the oil under strict conditions, bottle it quickly and sell it before oxidation occurs.

Industrial methods produce up to 30% more oil and ensure long shelf stability.
