First there was medical marijuana, then there was recreational marijuana, igniting a massive wave of new and exciting flower strains.
Then came even stronger strains, then came concentrates and edibles, and now we find ourselves in a dazzling world of shatter, waxes and boutique live resins.
But before we get into the best presses, from hand-powered manual options to pneumatic to electric, let’s dig a little bit more into just what this sticky magic actually is..
What IS Rosin?
Rosin is a concentrate made by exposing cannabis to heat and pressure to force out the terpenes and cannabinoids found in the plant’s trichome glands.
Rosin is also uniquely versatile in the fact that it can be manipulated into almost any type or texture of concentrate. From shatter and sugar to budder and wax, rosin has many adaptability options, making it an awesome product for extraction artists to experiment with.
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.
Understanding How Rosin Presses Work.
Temperature plays a big role in determining the quality and yield and the ideal temperature is heavily dependent on the chemical makeup of the cannabis used.
If your flowers, dry sift, or hash is terpene-rich, a lower temperature is needed. This is because the terpenes squeezed out of the trichome glands during the initial press act as a natural solvent to facilitate the rosin process.
With fewer terpenes to play that role, you’ll need more pressure and heat to coax the cannabinoids out of the glands.
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 compounds like CBD and terpenes.
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.
Which Rosin Press Should You Buy?
The main types of press are manual, hydraulic, pneumatic, electric, and hybrid. Each uses a different mechanism to apply the pressure.
When looking for the best rosin press, there are a few things we considered.
The Shape of the Plates – For Ease of Use & Efficiency
Rectangular plates work best. The ideal plate structure of a rosin press is longer and narrower. This is because this shape maximizes the perimeter of your press. A rectangular plate will normally outperform a square one.
Even Heat Distribution – For a Quality Product
Your rosin press should have uniform heat distribution. The way heat works to extract rosin is by melting the trichomes and other essential compounds into a lower viscous form. Many cheap rosin presses don’t have even heat distribution across their plates, and this leads to lower quality rosin.
Reliability – Consistent Mechanical Operation
Rosin presses can get pretty pricey. So, it makes sense to only invest in a press that will last you years to come.
So with all that said we’ll get into the best products in each category for manual presses, hydraulic, pneumatic, electric, and disel-powered.
Okay, we’re just kidding about the diesel option, but who knows, maybe one day!
With quality indicators out of the way you should start thinking about the volume of plant material you plan on processing in the next 1-5 years because there is no harm in buying a press that you can “grow into”.
Below are some of the best rosin press machines we could find, including models that come in under $300, under $500, and under $1000 respectively.
Best Manual Rosin Presses
What’s not to love about a simple, hand-crank, hand-powered rosin press that requires nothing but elbow grease to produce rosin?
Typically entry-level presses are manual presses and pressure is generated by a pull-down lever or through a twist-operation. Manual presses are going to be the best bang-for-buck options in the $300 price range.
Built like a beast, the DM1005 is easy to use with no additional equipment or parts required to start pressing. Right out of the box this thing is ready to go. The press features a locking lever mechanism and an innovation adjustable pressure knob that allows you to apply continuous pressure without constant use of manual force.
