When pressing rosin, there are multiple factors to consider; press temperature, time, pressure, and the type of press you’re using. It can be tough to figure out what the ideal press temperature is, so we’re hoping to help you answer that. The reality is, there is no “perfect” temperature. The right temperature depends on a number of things, and it’s only one of the factors that are going to determine the yield.
The Role of Heat In Rosin Pressing
Heat is needed to activate the cannabinoids and terpenes in cannabis. The challenge is that too much heat actually reduces the amount of both of these ingredients.
Ideally, when pressing rosin, you produce enough heat to activate the cannabinoids and terpenes, but not enough to rapidly reduce their availability. The risk with applying too much heat is that in layman’s terms, you’re essentially “burning them off”.
Without going off-topic, this is why pressure is an important consideration in any rosin press. Pressure helps to reduce the need for long high-heat exposure times.
What’s the Right Rosin Press Temperature?
To determine the right rosin press temperature, we have to first consider the quality of material you’re using. Different starting materials require different temperatures.
If you’re using flower, you’ll want to use one temperature, using a different material, you’ll want to use another. Here are a few guidelines:
When pressing dried flower, it’s typically recommended that you use a temperature between 190 to 230 degrees Fahrenheit. This is a higher temperature than other materials require. The dried flower as a starting point requires higher heat in order to produce quality rosin.
Something to consider when pressing dried flower is the amount of time you press for. Due to the higher heat requirement, you’ll press for a shorter amount of time. This will help improve the yield.
A pressing time of 60 to 120 seconds should work well, in some cases you may need a bit longer.
If you’re starting with sift, as opposed to flower, you’re going to be dropping your temperature. The quality of the sift will change the temperature you’ll need to use.
A really nice, high-quality sift means that you can press at a lower temperature. This lower temperature helps reduce the loss of any of the terpenes. Having a high-quality sift as your starting point means you’re probably in for a great press.
If you’re using a lower quality sift, you can press at a temperature that’s similar to dried flower (190 to 230 degrees), or slightly lower. However, you can press for a slightly longer time, typically in the three to four minute range.
When using a higher quality sift, you’ll want to lower the temperature a little bit to below 200 degrees.
Things To Note
The tough part about questions like “what rosin press temperature is right?” is that like we mentioned before, so much depends on factors besides heat. This means there’s no correct answer. Things like surface area, pressure, material, all play a huge role. Hopefully though, this gives you a good idea.
