Rosin has been around for a few years now and is increasingly becoming the go-to for many cannabis extract lovers. Why? Well, because unlike other methods that require the use of solvents like alcohol, rosin is an entirely natural and solvent-free extract.
Rosin has been around for a few years now and is increasingly becoming the go-to for many cannabis extract lovers. Why? Well, because unlike other methods that require the use of solvents like alcohol, rosin is an entirely natural and solvent-free concentrate extraction method.
The final product of extraction goes by the same name: Rosin. Similar in appearance to shatter, rosin is meant to be used in similar ways to other extracts like budder, wax, and shatter itself. While still differing in concentrations, appearance, texture, etc.
Contrary to other extraction methods that require solvents, decarboxylation processes, and other pesky little process nuisances, pressing your own rosin has never been easier. You’re only required to own a rosin press… and high-quality cannabis, of course. Some “artisanal” attempts at producing rosin include using a hair iron or clothing iron, which is certainly not recommended if you don’t want to end up wasting that “good stuff.”
Picking a rosin press can be an even bigger challenge than producing rosin altogether. The press you go with will ultimately depend on your production volume goals and the raw material you’ll be extracting the concentrate from (flower, kief, or hash). Which are not always evident until you start experimenting with the process and final product.
Because its one of the most popular forms of solventless extraction, many want to know what the best rosin press machine is.
How Rosin Presses Work?
The way a rosin press works is quite easy to understand. Simply put, a press is used to squeeze the material between two plates that heat up and distribute temperature evenly through the surface. As this happens, a gooey substance known as rosin will begin to ooze out of the raw material. That’s all it is!
Adequate temperature and pressure vary depending on the raw material used in the extraction process and imperative for high-quality rosin. This is why choosing a rosin press that meets your pressure and temperature requirements is so vital.
A few other things to keep in mind when choosing a product are heat distribution, the plate’s shape, and brand reliability.
The Rosin Extraction Process
The concept of extracting rosin is quite simple. Two heated plates are pressed on both sides of the desired starting material (which is enclosed in parchment paper or rosin pouches) at high pressure.
The heat from the plates loosens the resinous glands, or trichomes, that contains all of the plant’s cannabinoids while the pressure effectively squeezes it from the flower. This basic process is the foundation for rosin presses and the technology that makes them run.
Since rosin is produced without the use of solvents, which can change the flavor and finished product, it’s preferred by users who don’t want any chance of having lingering, man-made chemicals in their concentrates.
This extraction technique has been used by other industries for thousands of years. Imagine squeezing the oil out of olive or the juice from a grape. The rosin process presses the starting material until it produces a potent, solventless concentrate.
When it comes to electric rosin presses, they are the newest type and the simplest to use. These types operate at the push of a button just like pneumatic models but instead use an electric pump to run. This means you do not need an air compressor to operate it. The best part about these models is they are portable and can be used straight out of the box.
This high-quality press is capable of delivering over 8000 pounds of pressure. It comes equipped with a 4″ X 8″ heating plate area, this allows for significant production and fantastic yields.

What is the best temp to press rosin?
You may think that more heat will result in larger yields. This is not true! Using too much heat will burn off terpenes and other compounds that make rosin so sought after. You should stick to lower heat.
For flower: 220°F — 240°F for about 30–45 seconds
For dry sift/kief/hash: 180°F — 210°F for 45–90 seconds
As soon as you finish your press, remove rosin from the plates as fast as possible. This will minimize any degradation of active compounds and terpenes. ECO Farm rosin press makes some really cool Gold Plates which you can place your rosin on right after pressing to speed up cooling.
How much pressure do you need to press rosin?
The pressure needed will depend on the temps you use, but, also on what you’re pressing.
Flower needs more pressure, somewhere between 600–1000 PSI.
Dry sift/kief or hash will require less pressure because it is more concentrated. You should shoot for between 300–800 PSI.
Too much pressure can lead to a lower quality yield. You can actually end up squeezing plant matter into the rosin, resulting in impurities, poor taste, and overall lower quality.
Rosin Press Buyer´s Guide
You may want to check out the rosin press review before you buy one. Each rosin press, regardless of the type, can be assessed by the pressure it exerts, the quantity it squishes, and the temperature range it has.
However, aside from these basic requirements, you may want to invest in a quality machine that will last for years to come.
Here are some of the things you need to consider:
When I say quality, I do not just mean the quality of the press itself but also the quality of the concentrate it will produce.
The heat is directly responsible for quality maintenance. Too much heat can result in sub-par rosin that is almost burnt.
One way to control is with high pressure that yields more even at low temperatures.
Most people think the higher the pressure, the more yield the press would produce. On the contrary, extreme pressure may infiltrate the rosin with unwanted plant material.
The pressure should be high, but just high enough for the amount you are pressing.
Size is another important consideration when choosing a rosin press machine, especially if you are going to use it at home.
For a commercial setting, you normally would not care if it is too big or heavy.
However, for domestic extraction size has to be manageable and portable enough.
If you want a rosin press that does not make significant sound, you should not go for a pneumatic rosin press.
These use concentrated air for exerting pressure and can be fairly noisy. The electric ones would be the quietest among all.
Choosing the type of rosin press is directly going to affect your use, the yield, and most importantly, the price.
If you do not mind some manual labor, a manual rosin press would be best.
If you plan on using it for producing multiple batches at a time, go for the pneumatic or electric one.
Some rosin press models have advanced features that allow you to control temperature and pressure, to achieve different consistencies in rosin.
This depends on what your production goal is. If you like experimenting, I would recommend buying the best electric rosin press with digital control of time, temperature, and pressure.
These machines cost anywhere from a few hundred dollars to a few thousand dollars depending on the type and size of the press.
Most brands do offer long warranties. However, you should read in detail as to what parts the warranty is valid for and how long.
Dabbing or vaporizing rosin can be a great way to consume weed. However, if you are a fan of rosin, you will need the best rosin press machine to extract your own.
