Ethanol Cannabis Oil - RSO Style - Small Batch....Part One
I divided 2 ounces of trim into 3 jars of 20g each instead of just one jar. It was finely ground before I got it so as finely ground as it was, it would have been really hard to strain the whole amount at once and get a good recovery. The real reason I did that, though, is because I wanted to use the same alcohol to wash all three jars, thus increasing the potency each time instead of using a ton of very expensive Everclear just to evaporate it all off. I started with 12oz of alcohol in the first jar. Here are the steps:
The alcohol and cannabis portions are placed separately in the freezer for a minimum of 24 hours.
Place everything that is going to touch your alcohol-cannabis mixture in the freezer as well, including glass measuring cups, clean mason jars, filters and strainers and utensils. This is to reduce plant waxes and oils. Only take them out of the freezer as needed.
When ready to begin, have your first strainer, first jar of pot, cold glass measuring cup and alcohol in easy reach because the alcohol is only staying in the jar 30 seconds before draining.
Pour the amount of alcohol you're going to use for your first run (there are 2) into the cold measuring cup and then place the bottle back in the freezer. Pour this amount, while very cold, into your first jar of pot and shake lightly for 30 seconds.
Immediately strain your jar, leaving the cannabis inside. This could be 4-5 minutes if it's as fine as mine. I use a piece of silkscreen screwed over the top with just the lid ring.
After removing as much of the alcohol as possible without pressing, place the lid back on the jar and place it back in the freezer. Place the glass measuring cup with the first alcohol back in the freezer without filtering for a half hour. During that time clean your area and essential equipment in preparation for the next jar.
After 30 minutes, remove the second fresh jar of cannabis from the freezer as well as the saved alcohol in the cup. Repeat the last 3 steps above for each remaining jar. Be sure to place your jars and alcohol back in the freezer after each step. This picture shows me doing my 3rd jar. At this point after the first 2 jars, my 12oz of alcohol is down to 8oz before this step. Remember 30 seconds between the alcohol going in the jar and starting to come out.

Filter your extraction from the last jar. There isn't a need to filter the alcohol from each jar separately as long as most of the plant material was strained. After my 3rd jar I had a total of 4oz of extremely dark and thick solution out of the original 12oz I began with.

Place the filtered extraction from the first run in a jar in the freezer to start a bit of winterization.
This is the end of part one. The next post will cover the second run and actual making of the oil.
