Beyond flower, hemp offers a whole world of concentrates, from hash and kief to moonrocks and hash rocks. If you are exploring CBD concentrates in the UK, this complete guide explains every main type, how they compare and how to choose. It is information only, and we make no medical or health claims.
What are CBD concentrates?
A CBD concentrate is any product that concentrates the resin of hemp flower, the part rich in cannabinoids and terpenes, into a more potent form. Because the resin is separated from the bulk of the plant material, concentrates typically carry a higher CBD percentage by weight than loose flower. They come in many forms, each made differently.
The main types of CBD concentrate
Kief and pollen
Kief is the loose resin powder sieved from flower, the simplest concentrate of all. Left loose it is often sold as pollen, like our CBD pollen hash. Learn more in our guide, What Is Kief?
Hash
Hash is pressed resin, and it comes in many regional styles. Explore our guides on CBD hash, hemp hash, bubble hash, dry sift, Moroccan, Afghan and charas styles. Shop classics like Afghan CBD Hash and Amnesia CBD Hash.
Moonrocks and hash rocks
These are premium, layered concentrates. Moonrocks start with a flower bud coated in extract and kief, while hash rocks use a hash core. Our guide on hash rocks vs moonrocks explains the difference.
How concentrates compare to flower
Flower is the raw, whole bud; concentrates take the resin from that flower and pack it into a stronger form. If you are new to hemp, flower is usually the place to start, with concentrates as a next step once you know what you enjoy. See CBD hash vs flower for a direct comparison.
How strong are CBD concentrates?
Because they concentrate the resin, they generally carry a higher CBD percentage than flower. But strength varies widely by product and method, so the reliable measure is always the batch lab report (COA). Read our guide on CBD strength to understand the numbers.
Are CBD concentrates legal in the UK?
Hemp concentrates are derived from the cannabis plant, so like flower they sit in a legal grey area, even at very low THC. CBD itself is legal. See our guide, Is CBD Hash Legal in the UK? Information only, not legal advice.
How to choose and store concentrates
Buy lab-tested products from a transparent supplier, and check the COA. Our guide on spotting good quality hash applies to most concentrates. Store everything airtight, cool and dark to preserve aroma and potency.
Frequently asked questions
What is the strongest CBD concentrate?
It varies by product. Moonrocks and hash rocks are among the most concentrated formats, but only the COA confirms the actual CBD content.
Which concentrate is best for beginners?
Many people start with flower, then try pollen or hash. Go slowly and check the COA.
Do concentrates contain THC?
Quality hemp concentrates contain only trace THC and are not intended to be intoxicating. Confirm via the COA.
The bottom line
