Best Rosin Press 2021 For Flower, Kief or Hash

In the past, I’ve worked in a dispensary and one of the most popular products was rosin.

Why?

Rosin is generally described as a cleaner method of producing a concentrate as it does not require solvents. As a result, you can enjoy some of the most tasty cannabis concentrates because of its high terpene concentration.

But, to make this yourself you’re ideally going to need some specialized equipment; unless your going old school with a hair straightener and a buck load of luck.

So let’s dive in and find you the best rosin press for your needs! But, if you’re in a rush, here’s our 3 favorites:

How the Rosin Process Works

The way a rosin press works involves heat and pressure without using the solvents used to make other concentrates such as shatter, live resin, or wax

The starting material is placed between two plates. You then place the starting material in a bag with parchment paper surrounding it, and then pressure and heat are applied to remove extra plant material to create rosin. 

You then place this into extraction bags to hold onto your precious extraction. 

The rosin press needs a precise heat distribution to ensure the proper flow of extra plant material out of the bag you are using. 

While some people believe higher heat may create the best rosin, this is not the case. 

Why?

The aromatic terpenes and the bright yellow color that many rosin users seek is best achieved when the material spends minimal contact with heat.

The amount of pressure used is also essential. For example, the lower the heat, the more pressure you will need. Conversely, the more heat you use, the less pressure you will need. 

It is important to know what temperature and pressure will work better with the starting material you will use. However, lower heat is preferred because the terpenes and cannabinoids will slowly release to create a better end product.

To yield the desired rosin consistency and color, it also depends on the starting material used. 

The material can be either flower, hash, or dry-sift trichomes, and the color of your product will largely depend on the age and quality of your starting material.

Are Tons of Pressure Needed For Rosin Presses?

There is a large misconception that you need to have larger plates and a considerable tonnage to get the best product and the higher yield.

But, high pressure alone isn’t the best way to think about rosin presses. 

One of the first things you need to take into consideration is your starting material and what the best pressure (PSI) and yield are for this material.

For instance, if you are using bubble kief as your starting material, you should use a pressure between 300-700 psi which will have a maximum yield of 80%. 

For kief, the ideal range for the pressure per square inch is between 400-800 and has a maximum yield of 60%.

While using flower requires a range somewhere between 600 to 1000 psi and has a max yield of 30%.

Though you may desire a higher yield, it is best not to go over these guidelines as you may push fats, lipids, and chlorophyll into your rosin, which will decrease quality. This is especially the case when using high pressure. 

As a result, the best rosin press for you might not simply be the one that delivers the most power inch for inch. 

Rosin Presses & Heat Distribution 

Heat distribution also plays a significant factor in determining the best temperature to produce the desired end product. 

What you want is even heat distribution which will melt the trichome heads and stalks, lowering the product’s viscosity. When adding pressure, the less viscous cannabinoids are forced out of the filter bag.

Minor changes in temperature or variances in temperature across the heat plate can produce varied textures and flaws that can be avoided if you choose a plate with a consistent surface. 

Even heat is essential for maximum rosin flow, and cold spots will cause the flow rate to slow down. Generally, when this occurs, you will have to increase press time which will cause terpene degradation – something no one wants.

Or worse, the extraneous material will not flow out of the rosin bag at all and cause a bag blow out.

To avoid this, when choosing a plate, you should avoid presses with a U-shaped coil. This type of coil typically has a cool spot in the center, and the areas over the heating element are much hotter and may cause your material to burn.

Manual VS Electric, Hydraulic & Pneumatic Rosin Presses

One of the first things you need to consider on your search for the best rosin press is if you want a manual press, hydraulic press, pneumatic rosin press, or one which uses electricity to operate. 

Hobbyists favor manual powered rosin presses due to their low cost and portability. 

Manual Rosin presses do not require an air compressor or external pump to operate. These presses tend to use a hand crank or twist-style instrument to apply force to the material you are using.

Contrary to manual presses is the hydraulic rosin press. Hydraulic rosin presses utilize compressed fluids in a hydraulic cylinder to create pressure quickly. 

You can make great rosin with the hydraulic press, but again, it depends on your needs. A pneumatic rosin press is more consistent and reliable but it’s pricey.

A pneumatic rosin press uses air to create pressure and uses a pneumatic cylinder that requires no oiling or maintenance and, through its unique design, can reach up to 25 tons of pressure with the use of an air compressor. 

As a result, pneumatic presses are believed to be top of the line when it comes to choosing a rosin press.

Lastly, there are electric rosin presses. These do not need hand-cranked or pump and operate with a button or a switch. 

An electric rosin press is generally less powerful than pneumatic or hydraulic presses, making them more suited to personal use.

But, electric rosin presses are super easy to use making them some of the best rosin presses on the market for those who can afford one. 

As you can tell, there is a wide range of rosin presses, each with its strengths and weaknesses. 

Determine what type of press would work best for you, which will help narrow down your selection.

Buying Rosin Press Machines – The 4 Essentials

You should review four main factors when choosing a press:

The shape of the plates used in the press 

The best shape for wider and equalized pressure distribution is a rectangular plate. It should ideally be long and narrow as well. 

There are two reasons for this. One is the fact that rectangular plates maximize the perimeter to area ratio. Having a large perimeter is vital so that the rosin has the largest area from which to exit the material bag. 

This rectangular shape will help you increase your yield and remove extraneous plant matter from your rosin. 

The second reason a rectangle is the better choice is that the distance from the center of the bag to its edge is also minimized.

 If you use a press with a more considerable distance to the edge, this will increase the amount of time the material is in contact with heat. 

This distance is the most significant contributing factor to terpene degradation, which you definitely do not want. Also, oils may be trapped in the bag, which will decrease yields. 

The second most common shape is a square press. For the reasons stated above, these are not optimal for a rosin press. 

The perimeter to area ratio is not maximized, and the distance to the edges is not minimized, leading to terpene degradation, burning of your material, and extra plant matter remaining in your product.

The flexibility to adjust pressure and temperature

As noted, heat and pressure are the two main factors in creating rosin. You want the flexibility to adjust temperature and pressure. 

So ensure your rosin press has the ability to play with each, as manipulating these controls can result in different kinds of quality when it comes to output.

The ability to manipulate temperature and pressure also ensures that if you decide to use a different starting material, you will have the option to experiment. 

Then you can see which temperatures and pressures will best extract the most product you can get from your starting material without losing terpenes and corrupting the flavor.

Even if you are using just one kind of starting material, for example, flower, the different phytochemical makeup in each bud might require pressure and temperature alterations for the best result. 

Keep in mind that you ideally want something flexible regardless of whether you are using only flower to make rosin. That way, you will also have the option to use other starting material like kief or bubble hash.

Equal heat distribution throughout the plates

As mentioned previously, heat distributed evenly throughout the plates results in a consistent extraction process.

Most square plates use a U-shaped heating coil which doesn’t give an even heating surface. You want a plate that has a heating coil that consistently runs throughout the plate.

Another thing you may want to consider is what type of metal your plate is made of. Depending on the material, your heat may not distribute evenly based on its thermal conductivity. 

Thermal conductivity is a metal’s ability to transfer heat from its heating element to your material. It’s vital, and you should ask your press manufacturer what alloys are used for the plates if its unclear.  

The most common grade of aluminum used for rosin press heat plates is 6061 and is treated with magnesium and silicon.

For stainless steel, the alloys 304 and 3116 are the most popular and contain nickel and chromium. 

Each has its advantages and disadvantages, but aircraft-grade aluminum or alloy 6061is considered the best for an even transference of the heat to your material. 

How much material you are looking to press and the frequency of use

The last thing you should consider depends on how frequently you are planning on using the press.

Some options may seem expensive at first glance, such as the pure pressure manual press or the pikes peak, but these are the top of the line when it comes to presses.

As with anything, if you’re going to be using it often and making heaps of rosin, you probably want something that will stand the test of time and has all the bells and whistles to make your life easy. 

Follow these four guidelines, and you should be able to pick out which press best meets your needs.
