Pressing rosin from high-quality THCa flower ensures a potent and flavorful concentrate. Rosin pressing is a solventless extraction method that uses heat and pressure to squeeze out the purest form of cannabinoids and terpenes from THCa flower. This method preserves the potency and flavor of the flower while avoiding the need for solvents like butane or ethanol.
This guide will walk you through the process, covering everything from selecting the right flower to achieving the perfect press.
What You Need
Equipment & Tools
– Rosin Press – A dedicated press with heated plates
– Parchment Paper – Non-stick, food-grade parchment paper
– Micron Filter Bags – 25µm to 160µm (optional, but recommended)
– Pre-Press Mold – Helps compact flower into uniform pucks (optional)
– Infrared Thermometer – For monitoring heat consistency
– Rosin Collection Tool – A dab tool or scraper

Step-by-Step Process
1. Prepare Your THCa Flower
– Break down the buds: Do not grind the flower, as this can lead to plant material contaminating your rosin. Instead, gently break them into small, even pieces.
– Check humidity: If the flower is too dry, place it in a humidity-controlled jar with a humidity pack for 24 hours to rehydrate.
2. Load the Micron Filter Bag (Optional)
– Choose the right bag:
– 25µm – Best for dry sift or hash rosin
– 37µm – Best for finer material like kief
– 90µm-120µm – Ideal for pressing flower
– 160µm – Maximum yield, but lower purity
– Fill the bag evenly: Pack the flower evenly to avoid uneven pressure and prevent blowouts.
– Pre-press the material: Using a pre-press mold, compact the flower into a uniform puck for better extraction.
3. Set Your Rosin Press Temperature & Pressure
– Low Temp (160°F – 190°F)
– Higher terpene preservation
– Less yield but better quality
– Press for 90-180 seconds
– High Temp (190°F – 220°F)
– Higher yield
– May burn off some terpenes
– Press for 45-90 seconds
– Pressure Settings
– Start low (500-700 PSI) and gradually increase
– Final pressure: 1,000-2,000 PSI for flower
4. Press the Flower
– Place the parchment paper between the plates with the flower inside.
– Gradually apply pressure to avoid blowouts.
– Hold the pressure for the recommended time based on temperature.
– Check the rosin – You should see golden, syrup-like oil seeping out.
5. Collect and Store the Rosin
– Use a collection tool to gather the rosin while warm.
– Store in a silicone or glass jar in a cool, dark place.
– Cure the rosin (optional) – Let it sit at room temperature for 24-72 hours to develop a stable consistency.
Tips for the Best Results
– Use fresh, high-quality THCa flower for the best yield and purity.
– Experiment with temperatures to find the perfect balance between yield and flavor.
– Always use clean, high-quality parchment paper to avoid contamination.
– Be patient – Rosin pressing is as much an art as it is a science.
When selecting a strain for rosin pressing, consider factors such as trichome density, resin production, and overall flower quality. The strains mentioned above are known for their exceptional characteristics, making them suitable choices for producing high-quality rosin.
Note: Always ensure compliance with local laws and regulations regarding the purchase and use of hemp-derived products.
