Ethanol Extraction Recipe for One Ounce of Flower Material
Precautions and Safety Measures:
1. Perform the extraction in a well-ventilated area to prevent the buildup of flammable ethanol vapors. 2. Wear appropriate personal protective equipment, including gloves and safety glasses. 3. Keep all sources of ignition, such as open flames, sparks, and electrical devices, away from the extraction area. 4. Avoid smoking or using any flammable materials in the vicinity. 5. Ensure the kitchen is clean and free from clutter to minimize the risk of accidents.
Equipment and Materials:
1. 1 ounce (28 grams) of dried and cured cannabis flower material. 2. 2 cups (475 ml) of food-grade ethanol (e.g., 95% ethanol). 3. 2 wide-mouthed mason jars or glass containers. 4. Funnel. 5. Coffee filters or cheesecloth. 6. Heat-resistant double boiler or water bath. 7. Silicone spatula or stirring rod. 8. Scale for accurate measurements. 9. Glass syringes or dropper bottles for storage.
Step 1: Preparing the Cannabis:
1. Weigh 1 ounce (28 grams) of dried and cured cannabis flower material using a scale. 2. Break down the flower material into smaller pieces, ensuring uniformity for better extraction efficiency.
Step 2: Ethanol Extraction:
1. Pour 2 cups (475 ml) of food-grade ethanol into a glass container. 2. Add the prepared cannabis material to the container, ensuring it is fully submerged in the ethanol. 3. Seal the container with an airtight lid and gently shake to mix the contents.
Step 3: Soaking Period:
1. Place the sealed container in a dark, cool area, away from direct sunlight. 2. Allow the mixture to soak for 1 to 3 hours, occasionally agitating the container.
Step 4: Filtering the Extract:
1. Set up the funnel with a coffee filter or cheesecloth on top of a clean mason jar or glass container. 2. Pour the ethanol-cannabis mixture through the filter, collecting the liquid extract in the container. 3. Gently press the plant material with a silicone spatula or stirring rod to maximize extraction.
Step 5: Ethanol Evaporation:
1. Transfer the collected extract to a heat-resistant double boiler or water bath. 2. Heat the extract gently, allowing the ethanol to evaporate gradually. 3. Stir occasionally to aid the evaporation process and prevent scorching. 4. Ensure proper ventilation during the evaporation process.
Step 6: Storage:
1. Once the ethanol has evaporated, the concentrated extract can be transferred to glass syringes or dropper bottles for storage. 2. Label the containers with the strain and extraction date for future reference.
Cleanup and Disposal:
1. Clean all equipment, containers, and surfaces used in the extraction process with soap and warm water. 2. Dispose of any leftover plant material and filter materials appropriately, following local waste disposal guidelines.
