What Is CBD Hemp Rosin?

The CBD topic has probably made it to your dinner table more than once. If it has, you’ll know that CBD is a cannabinoid mainly extracted from hemp.

Like most cannabinoids, you can find CBD in many different product formats. These include topicals, edibles, and tinctures. You can also find CBD in the form of a concentrate, which is the primary raw material used to make the other finished goods mentioned above.

There are tons of concentrates to choose from. There are so many of them that it can be a tad confusing to select and use them.

Hemp Rosin is one of those concentrates. But what is it exactly?

If you’re interested in learning more about what CBD hemp rosin is and how to make it at home with just a few tools easily, then you’re at the right place.

What Is CBD Hemp Flower?

There are two primary varieties of the cannabis plant. 

One is marijuana, a psychoactive variety with a high THC concentration. THC is the primary psychoactive component found in cannabis.

The second variety is hemp. A non-psychoactive cannabis plant is characterized for having a low THC content and a higher CBD content than marijuana.

As of 2018, the marketing and production of hemp were declared federally legal, barring the fact that Delta-9 THC content does not surpass 0.3%. This has prompted an increase in hemp farming and hemp-derived products R&D.

CBD hemp flower is the raw or curated flower bud of the hemp plant. It is also known for having the highest concentration of CBD in comparison to other cannabis plant varieties. Because of this, its consumption has been associated with positive effects like pain relief, anxiolytic effects, seizure reduction, and anti-inflammatory properties [1,2,3,4].

All states follow their own Controlled Substances Acts (CSA). In most cases, this set of rules mirrors the federal government’s CSA, which would make CBD legal as long as Delta 9 THC content is under 0.3% per unit of dry weight. We would still suggest you check out your state’s laws about CBD before purchasing any CBD product.

What Is CBD Hemp Rosin?

CBD rosin is a solventless concentrate extracted from the hemp plant. It is manufactured by carefully applying pressure and heat to cured and dried hemp material. Contrary to solvent-based extractions, hemp rosin does not use any solvent and is made using only heat and pressure. 

The flower is the part of the plant that is usually used as a raw material for rosin extraction, but other parts like stems and leaves can also be used. Rosin extraction is a straightforward process that only requires a few materials and can even be made at home as a DIY product.

Seeds are never used in rosin. Hemp seeds are used to make hemp seed oil, which can also be used as a carrier for CBD and other cannabinoid extracts.

You can use many extraction processes to make cannabis concentrates, and they are all classified into two main types of methods; Solvent-based and solventless extraction.

Solvent extraction is done by running the hemp plant material through a solvent. By doing this, the cannabinoids are extracted into the liquid, which is then evaporated. 

Some of the most commonly used solvents are butane and ethanol. 

After the solvent has been evaporated, only an oily residue known as cannabis concentrate is left behind. The type of cannabis concentrate and the cannabinoids in it will depend on the extraction process used.

The only issue with solvent-based extraction is that you risk leaving solvent residue in your final concentrate. Serious companies like the ones you’ll find at Hemmfy do not have an issue with this because their process is standardized, and their product is constantly tested for safety and quality.

A solventless extraction is a chemical-free extraction method. Rosin is a perfect example of that because it uses nothing more than heat and pressure. This type of extraction method eliminates the risk of solvent residue.

How to Make CBD Hemp Rosin

The process of making top-notch CBD hemp rosin starts by selecting the most trichome-rich hemp flower buds you can find. The more the trichomes, the more the resin on the surface of the flower.

The more resinous trichomes you find on the CBD hemp flower, the more rosin you’ll be able to squeeze out of it.

Another essential feature to look out for in your hemp flower is humidity for CBD hemp rosin that would ideally sit between 55% and 62%. To meet those standards would likely mean you are sourcing your hemp flower from indoor growth operations. 

Outdoor growth operations are a bit harder to provide hemp flower that meets specific requirements because it’s harder to control variables like light exposure, humidity, and temperature.

How to Make CBD Hemp Rosin

Hemp is not as resinous as other cannabis varieties. This makes hemp rosin yield lower when compared to that of marijuana. With hemp, you can expect to yield results at around a 15% return.

Because of this, a higher plate temperature is needed when pressing hemp flower than when pressing marijuana. Another reason for this is that CBD has a higher melting point than THC.

You can make rosin that contains CBD with marijuana, but unless you add other steps to the process, you won’t isolate CBD from THC. Alon the same line, adding other steps will probably mean using solvents which entirely defeats the goal of producing rosin.

What You Need to Make CBD Hemp Rosin

While making high-quality rosin can be tricky, the theory of making it is effortless. These are the only three things you’ll need to get your rosin-making process started:

  1. CBD Hemp Flower
  2. Parchment Paper
  3. Rosing Press

Pressing CBD Hemp Flower [A Step-by-Step Process]

Once you’ve purchased your rosin press of preference and read the manual, all you have to do is follow the following steps:

1. Prepare a Micron Screen

Your rosin press should come with a few micron screens. If not, you can quickly purchase one online. Micron screens with more refined filters will provide lower yields but also higher quality rosin. You can define which screen filter size fits your purpose the best. 

Once you’ve done this, make sure that the seam of your filter bag is sitting on the inside, this ensures that less rosin will end up sitting in the seam. If you forget to do this, then definitely don’t forget to squeeze the rosin in the seam afterward.

2. Preparing to Press

Place your CBD hemp flower inside the filter bag and pack it tightly. You’ll also want to fold the bag closed so that flower doesn’t fall out once you start pressing it. The amount of flower you use will depend on your goal, filter bag, and rosin press size.

3. Prepare Parchment Paper

The parchment paper is used to protect your press's heating plates and avoid rosin sticking to them. To prepare it; take a large piece of paper, fold it in half, and place it between the plates with the open end facing out. Some rosin presses will have clips that help you secure the parchment paper.

4. Pressure and Heat Settings

Pressing CBD hemp flower to make rosin has many variations. Specifically heat settings and the amount of time you apply pressure to the flower. By playing around with these variables, you’ll get different yields and consistencies. Your rosin press should come with a set of instructions for each setting, but overall higher temperatures provide bigger yields, and lower temperatures provide a denser consistency.

A solid option is to keep temperatures at around 100 degrees C. and apply pressure for 45 seconds to three minutes.

5. Start Pressing

At this stage, you’ll place your bag in between the two plates that you’ve previously covered with parchment paper. After that, you can start pressing once you’ve made sure that the packed bag is secure in between the two plates.

Once you’re done, take the parchment paper out, and the golden-brown material you find on it is your rosin. All you have to do now is scrape it off, store it for later use, or consume it right away.

Be warned that CBD hemp flower rosin yields are not excellent. So if you want to have more significant gains, you might want to look into using hemp flower hash to press instead of dry flower.


Hemp flower is a variety of cannabis flower with low THC content and a higher CBD concentration. After the 2018 farm bill's passing in the U.S., the hemp market is expected to grow exponentially in the next five years. We will not share the projection numbers as they cannot be confirmed, but they look incredibly promising based on their evolution in the past three years.

With the increase in hemp farming, manufacturers are constantly investing in the research and development of new finished goods that use hemp as a raw material. One of those products is a solventless concentrate called CBD hemp rosin. Making CBD hemp rosin is very simple in theory because only pressure and heat are required to make it.

Hemmfy articles and blogs are meant to entertain and educate. However, we are not medical professionals and do not intend to give medical advice through them.

The knowledge around CBD and other cannabis-derived products is growing and constantly changing, as does their legal status. Hence, we recommend checking with your local authorities and a licensed physician prior to consumption.
