CBD Extracts Guide: Everything About CBD Concentrates and Extraction Methods

CBD extracts are concentrates obtained from the cannabis plant through various CBD extraction methods. Compared to other products like flowers, CBD extracts offer a much higher concentration of cannabidiol — often between 50% and 99% of pure CBD. They are premium products for people who want the most in terms of potency and purity.
But what are CBD extracts exactly? What types of extracts are there? How is CBD extracted from the hemp plant? And what distinguishes a high quality extract from a mediocre one? In this article, you will find everything you need to know about CBD concentrates, the extraction process and how to use them.
What Is CBD? Understanding CBD Cannabidiol
CBD, or cannabidiol, is one of the most abundant natural compounds found in the cannabis plant. CBD or cannabidiol is a non psychoactive cannabinoid, which means it does not produce the "high" associated with THC. Unlike THC, CBD is legal in most countries when derived from hemp plants with THC content within legal limits.
CBD is extracted from the hemp plant using various extraction methods, and it can be used in many different forms — CBD oil, e-liquids, topicals and, of course, CBD extracts and concentrates. CBD is known for its potential benefits, including support for relaxation, sleep and overall well-being.
Why Choose CBD Extracts
The advantages of CBD extracts compared to other CBD products:
- High concentration: CBD extracts contain a much higher amount of cannabidiol than flowers — up to 99% in CBD crystals
- Purity: the extraction process removes the plant material, leaving only the desired compounds
- Versatility: CBD extracts can be vaporised, added to oils, used in cooking or applied in various ways
- Efficiency: a small amount of extract contains as much CBD as a much larger quantity of flowers
Types of CBD Extracts
The market offers many different types of CBD extracts, each with unique characteristics. Here are the main types you should know about.
Shatter CBD
Shatter is a CBD extract with a glassy, transparent consistency — it "shatters" like glass (hence the name). The consistency is hard and brittle, the colour ranges from golden to amber yellow. Shatter CBD is one of the most pure extracts because the extraction process and purification removes most impurities from the plant material.
Shatter CBD has a high cannabidiol content and a well-defined cannabinoid profile. It is ideal for vaporisation — heat melts it, releasing a vapour rich in CBD and terpenes.
Wax CBD
Wax CBD has a waxy, soft consistency — it can be easily moulded between fingers. The colour is generally opaque gold. Wax is a popular CBD extract due to its practicality — it is easy to dose and to use with a concentrate vaporiser.
The consistency of wax CBD depends on the extraction process and the processing temperature. Unlike shatter, wax maintains a softer structure due to the presence of air in the material.
Rosin CBD
Rosin is a CBD extract obtained without the use of solvents — the extraction process uses only heat and pressure. The plant material (hemp flowers or hash) is pressed between two heated plates, and the resin rich in CBD flows out as a golden oil.
The advantages of rosin CBD:
- No solvents: this extraction method does not use ethanol, butane or other chemical solvents
- Terpenes preserved: the low-temperature method preserves the terpenes and aromatic compounds of the plant
- Safe production: no risk related to flammable solvents
- Natural purity: rosin is a completely natural extract
Rosin CBD is considered one of the most prized CBD extracts due to its purity and its intact aroma profile. This extraction method produces a concentrate with an exceptional flavour.
Crumble CBD
Crumble is a CBD extract with a crumbly consistency — it breaks apart easily (hence the name). The colour is generally golden yellow and the consistency is dry and granular. Crumble CBD is produced through an extraction process that includes a low-temperature purification phase to remove residual moisture.
Crumble is a practical type of extract that is easy to dose. You can add it to CBD flowers for vaporisation, dissolve it in oils, or use it directly with a concentrate vaporiser.
CBD Crystals (CBD Isolate)
CBD crystals are the most pure form of cannabidiol available — up to 99% pure CBD. CBD crystals appear as a white crystalline powder, completely free of THC, terpenes and other compounds. They are CBD isolate in its most concentrated form.
CBD crystals are ideal for:
- Precise dosage: every milligram of CBD crystals is practically pure CBD
- Total versatility: CBD crystals can be dissolved in oil to create a personalised CBD oil, added to beverages, used in cooking or vaporised
- No taste: CBD crystals do not have the herbal taste of other extracts — perfect for people who do not like the taste of hemp
Moon Rock CBD
Moon Rock CBD is a unique product: hemp CBD flowers coated in CBD oil and then rolled in CBD crystals or pollen. The result is an extremely potent concentrate with a lunar appearance — hence the name "Moon Rock." They represent the best of CBD extracts for those who want maximum potency and an intense experience.

CBD Extraction Methods: How to Extract CBD from the Plant
The CBD extraction methods used determine the quality, purity and compound profile of the final product. Understanding how to extract CBD is important for choosing high quality products. Here are the main extraction methods used in the production of CBD extracts.
CO2 Extraction (Supercritical Carbon Dioxide)
CO2 extraction is considered the best CBD extraction method for producing high quality CBD extracts. In this extraction process, carbon dioxide is brought to a supercritical state — at specific temperatures and pressures, CO2 behaves as both a gas and a liquid, becoming a powerful solvent.
The CO2 extraction process works like this:
- Supercritical CO2 is passed through the plant material (hemp flowers and buds)
- The carbon dioxide extracts the cannabinoids, terpenes and other compounds from the plant material
- The CO2 is then returned to its gaseous state, evaporating completely and leaving only the pure extract
The most common advantages of this extraction method:
- No solvent residue: the CO2 evaporates completely, leaving a clean extract
- Selectivity: by adjusting temperature and pressure, it is possible to extract specific compounds
- Superior quality: this method produces the most pure and safe CBD extracts
- Terpenes preserved: low temperatures preserve the aromatic natural compounds
CO2 extraction requires expensive equipment, which is why extracts produced with this method tend to be more expensive. But the quality of the final product is incomparable.
Extraction with Solvents: Ethanol and Hydrocarbon Extraction
Extraction with solvents is a more economical but effective method. The most commonly used solvents are ethanol (ethyl alcohol) and butane.
Ethanol extraction: ethanol is used to dissolve the cannabinoids from the plant material. Ethanol extraction is safe and produces extracts of good quality. Ethanol is a food-grade solvent and residues are generally minimal. This extraction method is the most common for large-scale production of CBD products. Ethanol is also versatile — it can be used to extract a wide range of cannabinoids and terpenes from the plant material.
Hydrocarbon extraction (BHO): butane is a very efficient solvent that produces potent concentrates. However, butane is flammable and requires rigorous purification processes to ensure the final product is free of solvent residues. High quality BHO CBD extracts go through vacuum purging to guarantee the absence of residual solvents.
Solventless Extraction (Rosin Method)
Solventless extraction uses only heat and pressure to separate the resin from the plant material. This method is the most natural:
- Hemp flowers or hash are positioned between two plates
- The plates are heated (80-120C) and pressed together
- The resin flows out from the plant material under the effect of heat and pressure
- The resin is collected — this is rosin, a pure and natural CBD extract
The advantage of solventless extraction is total purity and safety of the process. No chemical solvents, no residues — just CBD, cannabinoids and terpenes from the hemp plant.
Full Spectrum, Broad Spectrum and CBD Isolate
Understanding the different spectrum types is important when choosing CBD extracts.
Full Spectrum CBD Extracts
Full spectrum CBD extracts contain CBD along with all the other cannabinoids and terpenes found in the hemp plant — including trace amounts of THC (within legal limits). Full spectrum products offer the entourage effect, where all the natural compounds work together synergistically. Many people prefer full spectrum CBD because it is believed to be the most effective form.
Broad Spectrum CBD Extracts
Broad spectrum extracts contain CBD and other cannabinoids but with THC completely removed. They offer some of the entourage effect without any THC content.
CBD Isolate
CBD isolate is the purest form of CBD — 99%+ pure cannabidiol with no other cannabinoids, terpenes or compounds. It is ideal if you want precise dosage and prefer to avoid THC entirely.
How to Use CBD Extracts
CBD extracts are versatile and can be used in various ways. Here is how to consume and use them.
Vaporisation (Dabbing)
Vaporisation is the most popular way to consume CBD extracts. With a concentrate vaporiser (dab rig or dab pen), the extract is heated to produce a vapour rich in cannabidiol and terpenes. Dabbing offers an intense experience — the effects of CBD can be felt in just a few minutes.
Adding to CBD Flowers
CBD extracts can be added to hemp flowers to boost their effects. A bit of crumble or wax CBD on the flowers before vaporisation significantly increases the CBD concentration.
Making Personalised CBD Oil
CBD crystals can be dissolved in a carrier oil (hemp seed oil, MCT oil) to create a CBD oil with the desired concentration. This is an economical way to make your own CBD oil.
Use in Cooking
CBD extracts — particularly CBD crystals — can be used in cooking. CBD is fat-soluble: dissolve it in butter or oil before adding it to recipes.

How to Choose the Right CBD Extracts
Here are the considerations for choosing high quality CBD extracts. It is important to know what to look for.
Extraction Method
Extracts produced with supercritical CO2 extraction or the rosin method are generally the best in terms of quality and purity. Extracts made with solvents can also be good if the extraction process includes adequate purification.
