Temperature is one of the key variables for extractors to control while pressing rosin. The type of starting material determines the best temperature to target, but there’s a range of temperatures that can deliver good results. Aiming for the higher end of that range is considered pressing rosin at higher temps, and it offers some advantages over pressing rosin at lower temperatures.

Before we look at the benefits to pressing rosin at higher temperatures, let’s review the suggested temperature ranges for each type of starting material.

General Temperature Guidelines for Pressing Rosin (degrees Fahrenheit):

Flower: 180-220
Bubble Hash: 140-200
Dry Sift: 140-200

Pressing Rosin at Higher Temperatures

Aiming for the hotter end of the spectrum, we consider pressing rosin at higher temperatures to target the following ranges:

Flower: 200-220
Bubble Hash: 180-200
Dry Sift: 180-200

Regardless of the type of starting material, it’s recommended to keep temps below 220 degrees Fahrenheit.

Benefits of Pressing Rosin at Higher Temperatures

Pressing at higher temperatures leads to greater yields than pressing at lower temperatures, as more heat tends to allow a greater percentage of the plant oils to flow out from the material. 

A shatter-type consistency is also a benefit to pressing with higher temps, if that hard sap-like texture and consistency is what you prefer. Learn more about the different consistencies of rosin in our Guide To Different Rosin Consistencies. 

Potential Downsides to Pressing Rosin at Higher Temperatures

Terpene loss and darker color are potential downsides of pressing rosin at higher temperatures. Terpenes are very volatile, and with exposure to heat they readily disappear. Terpenes improve flavor and enhance effect, so protecting and preserving them is definitely worthwhile. 

Another potential downside has to do with rosin color. While color by itself isn’t a sure indicator of quality, the perception is that lighter color reflects higher quality. Higher temperatures during extraction can cause a darkening in color. 

That said, older starting material that’s been significantly oxidized can also lead to darker color. 

Conclusion

Pressing rosin with higher temperatures can increase yields and impact consistency. If your goal with extraction is to maximize your returns on every gram of starting material, and you don't mind some terpene loss or a bit darker color, then try to press with temperatures at the hotter end of the spectrum. Also, if you prefer a shatter-type consistency in your rosin, high temperature pressing is probably the best approach for you.

What is considered higher temps for pressing dry sift rosin? 
180-200 degrees Fahrenheit is considered pressing dry sift rosin at higher temperatures. 

Is it better to press rosin with higher temperatures? 
Pressing rosin at higher temperatures has the benefit of increasing yield. If maximizing yield is your main goal, pressing with higher temperatures is probably your best bet. Higher temps can also make a shatter-type consistency, which some extractors prefer. 

What is the downside to pressing rosin with higher temperatures?
Darker color and terpene loss are a couple potential downsides to pressing rosin with higher temperatures.
