![]() Hot Pressing: High temperatures are more likely to produce a shatter, or taffy effect in consistency. Cold Pressing and Hot Pressing affects those qualities in different ways. The amount of heat used during extraction impacts the consistency, color, terpene content, and flavor of rosin. Here is a breakdown of Hot Pressing and Cold Pressing temperatures for the three types of cannabis source material, in Fahrenheit: Within normal ranges of pressing, cold pressing refers to pressing with temperatures on the lower side, while hot pressing is pressing with temperatures at the higher, hotter end of the spectrum. There are advantages to both approaches, and both sides offer compelling arguments for their preferred temperature. Don’t try to keep everything in your head! As you’re learning which temperatures work best for your source material, taking notes is an invaluable practice.ĭiscussions about temperature generally divide rosin enthusiasts into two camps: Hot Pressing and Cold Pressing. Taking notes is always a great practice in rosin extraction, and can lead you to many insights when working with different cultivars and types of starting material. ![]() Some strains will need either higher or lower temperatures to produce rosin that has the qualities most important to you. Many outcomes in solventless extraction are the result of the source material’s genetics, so experimenting with the different inputs as you press different strains of cannabis is key. ![]() Sometimes, greater levels of heat allow you to use lesser amounts of pressure, and visa versa. Therefore, consider adjusting only one variable at a time, to get a clearer sense of how that single variable is impacting extraction. Solventless extraction relies on the interplay of heat and pressure, and both inputs work together rather than independently of each other. Point the laser from the digital thermometer onto the tape, which helps to minimize diffusion from the shiny aluminum of the rosin plates and provides a more accurate reading with the digital thermometer.Įxperimenting with Temperatures for Rosin Extraction Use a digital thermometer to get a true reading of your temperatures at the rosin plates by placing a piece of tape on the plates where you aim the laser. Pressing cannabis flower requires more heat, in order to allow the trichome heads to separate and flow out of the source material.įor example, if you’re aiming for a buddery texture when pressing flower rosin, aim to use cooler temperatures within the flower rosin pressing ranges.ĭigital thermometers are great for measuring the temperatures during extraction with accuracy. With bubble hash, we’ve already separated the trichome heads from the rest of the plant material, so less heat is needed to create rosin. The following are our temperature guidelines for rosin, measured in degrees Fahrenheit: We need heat to transform the state of the cannabis trichomes from a solid to a liquid, but too much or too little can have negative effects. The amount of heat used during extraction impacts the final quality of rosin in several ways. By experimenting within broad temperature ranges we get a sense of how our source material performs under certain specific temperatures. The right amount of heat needed to press quality rosin depends largely on the type of source material being pressed. ![]() An understanding of ideal temperature ranges, and the ability to control the temperature within those ranges during extraction, are must-haves in the extractor’s toolkit. While pressure is needed to amplify the flow of rosin between heated rosin plates, it’s the heat generated between your rosin plates that allow cannabis trichomes to liquefy in a way that we can isolate them for collection. Heat is one of the key ingredients that makes pressing rosin possible. ![]()
