RSO 2.0 - A Classic Recipe Updated.
1 February 2022
Making Cleaner Oil in the kitchen.
In the early 2000’s, Rick Simpson brought the healing quality of cannabis oil to the masses using simple extraction techniques. In the larger picture of extraction processes, this methodology is simple and oils are crude. Since the time Rick introduced his original process, the art of home extraction has continued to evolve. RSO 2.0 bundles up the best of these changes and adds a few interesting advances.
This project focuses on making cleaner RSO at home using simple consumer kitchen tools, foregoing the elaborate technologies like vacuum driven distilling or lab styled filtration systems. RSO no longer has to be burnt gritty tar.
Something borrowed, Something new, Something clean.
#1 - A room temperature form of 'Winterization' has been developed and used here for removing 'gums', a . These are unwelcome plant compounds contaminating RSO to this day. This new step has been named "Silting" since it can turn a wash into an algae pond. Silting works to collect phospholipids and proteins that can be quickly filtered out at room temperature. The magic? Lime Juice and Club Soda!
#2 - This new process embraces Isopropyl Alcohol as the bulk solvent for extraction, with Ethanol saved for the final reduction. Isopropyl's chemical characteristics have advantages over Ethanol for the bulk work. This means only 2 ounces of Ethanol is needed per extraction. Making safe oil with Isopropyl does require the use of USP-NF or higher grades of Isopropyl. Even at specialized prices, its half the cost of heavily taxed Ethanol.
The controversy over using Isopropyl for extraction has been debated ad nauseam for decades. The issue was studied and a post written. The Result? Cannabis Home Sciences endorses using USP-NF or higher grades of Isopropyl for home extractions. A safeguard for removing 'residual solvents' is built into the distillation step. Three lab test results are available for review.
#3. A novel addition to this process is using Brine water to drive distillation. By using Brine, the Isopropyl and water Azeotrope is momentarily suspended, changing the dynamics of simple distillation favorably in our advantage. This neat trick is only works with Isopropyl. The use of Brine during distillation has been significant at all sorts of different levels:
That covers the theory. Here are three ways to make oil using these ideas.
Start simple, and when ready, add additional steps.
#1 Fast Path to La Brea. This uses the fewest steps and is most comparable to the original RSO. You do get cleaner oil with the Brine aborbing the water soluble impurities.
#2 Slow Path. Silting is added to remove fats and proteins.
#3 Slowest Path. Lastly, Winterization is added to remove waxes. This is the cleanest oil but takes 2 days.
#1 Fast Path to La Brea, a clean RSO. Extraction in an afternoon.
The following subset of videos are the fewest steps to a fast and clean RSO. Even cleaner oil can be made using the slower approaches presented below.
#2 Slow Path for making a cleaner RSO. Extraction in a day.
The following adds Silting for a clean RSO. The finest oil can be made using the slowest approach presented below.
#3 Slowest Path making the cleanest RSO with attention to detail. Extraction in two days.
Here is the full time consuming process. This involves using the freezer for Cold Washing, Silting and Winterizing. The inconvenience of longer processing time is offset by making the cleanest oil.
