The Rosin Tech method is a simple, solvent-free way to extract potent cannabis concentrates right at home. Here’s how it works: Take your dried and cured buds, trim, kief, or even pollen, and place them neatly inside parchment paper. Using a heated press, typically set between 70°C and 120°C, apply firm pressure for just a few minutes. This causes the cannabinoid-rich resin, known as rosin, to ooze out, leaving unwanted plant material behind.

To achieve the best quality rosin! Instead of wrapping plant material directly in parchment paper, place your plant material in the Rosin Filter Bag, then wrap the filter bag in parchment paper. This setup allows for cleaner extraction and easier cleanup. The extraction process can typically be repeated up to four times, depending on the desired level of purity. The non-stick interior makes it easy to remove plant material. Crafted from tear and heat-resistant nylon, Rosin Filter Bags withstand temperatures up to 240°C.

It’s safe, clean, and free from chemical solvents, meaning you skip the risks of explosive extractions. The process preserves more cannabinoids and terpenes compared to other methods, delivering a concentrate that is not only more potent but also rich in flavor. Whether you’re after stronger effects than raw flower or you simply want an easy and reliable extraction method.

Choosing the right size depends on your goal. For buds and trim, around 120 microns strikes a good balance—allowing resin trichomes to pass while filtering out unwanted plant material. For dry sift, kief, or pollen, opt for a finer screen—30 or 50 microns. These capture the delicate trichomes more effectively, resulting in a cleaner, more potent extract. Keep in mind: lower microns produce higher-quality concentrates but with lower yields, while high microns offer bigger yields at a slightly lower quality.

For consistent, high-quality extractions, it's advisable to use a fresh bag every time. This ensures optimal pressure, filtration, and purity, preserving the integrity of your product and process. If you reuse a bag, be aware that the filter bag mesh may still contain residue from the previous press.
