Top 6 Tips for Making High-Quality Rosin

Are you dreaming of producing high-quality rosin or getting perfect and higher yields? But, the problem is you don’t know where to start and what are the ways that you’ll do to get this “perfect rosin”? Well, your worries will finally end here because we got it all for you!

As America’s Trusted Garden store, we believe that many in the rosin community have misconceptions in making rosin. Most thought that by having larger plates with a huge carrying capacity is the answer in having higher yields. Well, always keep in mind that this is not necessarily the case.

Most rosin producers treat extraction as an art rather than a spectrum of science. For them, extracting rosin is like creating an artwork that needs precise materials and accurate steps to have a high output at the end. Here’s a quick tip for you! Always remember this rule of extraction “if you use high-quality input materials, you will also get the high-quality output.” And so, if you use a low-quality flower; as a result, you will also get low-quality rosin, no matter how accurate your process is. Keep in mind that nothing affects the quality of your product more than the quality of your materials.

Moreover, people do always love the bright yellow color and aromatic terpenes in rosin that’s caused by extracting small batches where the materials have spent less time with heat contact. This golden yellow color is most usually caused by the age and quality of the materials. However, take note that if you applied too much pressure, there is a high probability that extra plant matter can reduce the quality of the final output.

Thus, getting perfect-made rosin needs exact heat distribution to ensure proper flow and the appropriate amount of pressure. With this, you need to use the best temperature, pressure and time settings while pressing, as well as, finding their right balance is a major plus for it plays a vital role in the whole extraction process. Humidity and high-quality materials are also essential factors in the process.

Since you already have a short background of how to make perfect rosin, this will now lead you to the main question, “What’s the Best Materials, Humidity, Temperature and Time, Micron Bag, Pressure, and PSI” to have high-quality rosin?

Choose the BEST Materials 

In the rosin industry it will always be Quality as a King and followed by freshness. There many customers who always have complains about getting average and disappointing results after pressing flowers.

The main cause of their problems is that they always tend to forget that they are using average flowers, which is alright. But, if you want to have that stellar results, you must need competent materials also. This doesn’t necessarily need you to purchase “Platinum” shelf buds at the market, but with rosin, your results are mostly predetermined in the garden if your press is up to par.

On the other hand, Quality is also connected to freshness. You will see you deserved best results when pressing flowers as soon as after they are dried and cured as possible. Make sure to press buds as fresh as it can be because the longer you wait, the darker it will be.

To wrap it up, you must always take note that the biggest determination for yield, flavor, and quality is depending on how great the material was grown and how strong its genetics in the first place.

Choose the BEST Humidity  

If you are first-timers in pressing rosin and wonder why you get low yields, it’s because you used flowers that are too dry. Thus, using relative humidity comes in! Remember that relative humidity of your plant material plays a major role in your yield.

However, be careful! Because Relative Humidity can either makes or breaks your yields. The humidity and moisture content of your buds can bring a great impact to your flower rosin yields.

If your flower is very dry it will be like a sponge when the trichomes are liquefied, thus soaking up much of the rosin before it has a chance to escape. Lastly, take note of this important thing when pressing your flowers: You must ensure that the relative humidity content of your material is at least 55% to 62% for desirable results.

Choose the BEST Temperature 

When pressing rosin, the temperature is considered as a crucial factor because up until now it’s still the most debated factor in rosin pressing. Some would always push to do hot pressing while others go for cold pressing. So, what’s really the best press to use? The answer to this confusing question is that just choose a temperature depending on your desired results!

If you’re already started pressing and able to apply heat and pressure to your flower, you should know that the speed and consistency in which the trichomes liquefy completely depends on the temperature that is being applied. As well as the equality of the heat distribution.

To cut all the debates about this, there are actually two accepted ranges within which to press any type of rosin:

Moreover, to make it clearer the 210°F - 220°F range of temperature offers a great compromise between quality and yield. If terpene preservation and quality is your main goal then, you should probably start colder and evaluate your results. However, using this range may give very little terpene loss. On the other hand, there are also some who uses above 235°F in range, but according to them, there are flavor and terpene losses. Some also pressed at as high as 250°F. Furthermore, at the end of the day, it’s still up to you to choose and see what range works perfectly for you!

Choose the BEST Micron Bags

Choosing the right micron bag is also a great help for you to produce high-quality rosin. But, if you want to press flower rosin without using a bag it’s still alright however you are expected to get bits of plant material in your rosin as a result.

If you are pressing using a rosin filter bag, then, you just need to know that having the right micron screen size is beneficial in order for you to bull’s eye a high-quality yield.

Take note of this rule of thumb: “you should never press flower rosin beyond 90-micron width because if you do that the yield will be sacrificed and of course, it will result to the low-quality output. Meanwhile, if you use above 150-micron width it’s really not a good idea as well.” Always remember that there’s an important relationship between the micron type and material type because the higher the micron count, the more permeable the mesh filter is.


Lastly, if you’re pressing in a bag to use 100% polyester monofilament filter mesh, which is considered as the most conducive for yields and FDA’s top recommended food grade fabrics. Please be reminded that stainless steel screens are close to scratching plates and cutting yields, meanwhile, silk screens stretch an essential amount, making it hard to precisely monitor your pressure data.

Choose the BEST Pressure

In extraction process of rosin, pressure also plays a significant role. Here’s a quick trivia for you: “Extra Pressure Doesn't Always Make a Difference”

To explain it further, flower rosin needs more pressure than kief and hash rosin in order to squeeze all the juice out, but when high tonnage presses are applied it can be considered as absolutely overkilled.

Thus, the ideal pressure range for flower rosin is between 550 - 1,500 PSI at the plate, with maximum quality being on the lower end of that range. Some use DIY bottle jack presses which give them as many as 20 tons or more of pressure, but at very high applications of force. However, using this may give you undesirable particles and plant lipids that can be extruded into your rosin.

Lastly, there are some rosin producers who successfully get their desired yields and in fact, get yields above 25% at as low as 550 PSI while pressing high-quality buds with proper moisture levels in a 115-micron rosin filter bag.

Choose the BEST PSI

Always remember that the ideal PSI ranges from 300 to 1000, with more pressure required for flower and less for kief or hash. To give you detailed information for the best range for hash, kief and flower are, check below:

  • Ideal PSI For Hash: 300 to 700 psi
  • Ideal PSI for Dry Sift/Kief: 400 to 800 psi
  • Ideal PSI for Flower: 600 to 1000 psi

In order for you to understand the calculation clearer, let’s solve this given example and let’s calculate how much pressing power you need, in order to come up the required psi. For this example, 1000 psi is your goal, and the highest you’ll ever need. PSI is also known as pounds per square inch, thus, it’s simply calculated by just taking the total pressing power (in pounds) and dividing by the total pressing area (in square inches).


PSI = Pressing Power / Pressing Area

Then, substitute the give PSI which is 1000:

1000 psi = Pressing Power / Pressing Area

Don’t worry because you can also figure out the pressing area. Make a 2 by 6-inch bag as your example and the surface area of that bag is 12 square inches. Now you have: 1000 psi = Pressing Power / 12 sq in

After, in order to calculate the pressing power that is needed, you must multiply both sides of that equation by 12:

Thus, 12 sq in x 1000 psi = Pressing Power x 12 sq in / 12 sq in

Take note that the two (12 sq in) on the right side of the equation must be canceled, leaving you: 12,000 pounds = Pressing Power

So, 12,000 pounds is 6 tons, which means you would need a press capable of delivering 6 tons to deliver the pressure you need. Remember that you did this calculation assuming you want the possible maximum needed pressure of 1000 psi. Actually, you rarely need that much if you only press flower hash or kief. Now, this leaves you the question: do really need a 20-ton press? Or 12 tons is already enough? Just a quick reminder! Especially for the newbies in this industry, make sure that your calculations are enough and not arriving at too much or lacking results in order to have a smooth extraction process.

Furthermore, if you’re still confused about the calculations above then read this carefully, you actually don’t need 20 tons of pressing power because even for the largest bags, 12 tons will be enough and 15 tons is the max. Meanwhile, if you only have smaller amounts, you don’t need more than 5 tons and 2 tons is already enough for personal use pressing.

Finally, please do remember always that the more pressure you put on your material, the more plant matter ends up getting pressed out and into your extract. Thus, it will give you less pure and dark or green rosin and at the end of the day, it will only frustrate you.
