[2020 Update: This was an experiment, and is not a necessary step in making cannabis infused coconut oil. Some readers have had issues with the weed wash technique, especially if using lecithin in the infusion or if using another oil. I've only tried this with coconut oil that did not include lecithin and as you see from the experiment below, it can be temperamental. Some readers love it so we're keeping it up if you want to experiment with it.]
To avoid the issue of non separation (aka soggy weed oil) is to add the lecithin to the infused coconut oil after the weed wash. Another is to use concentrates to reduce the flavor in your infusion. [Please let us know in the comments below if you love another method that you'd like to share. This is a community and we all learn better from everyone's experiences ?]
One of the questions I get asked the most is “How do I get some of the “weed taste” out of weed oil?”
If you know me at all, you know that I love the taste of my weed oil. The pot that the farmer and I grow is some dank organic greenhouse nugget and we get to choose our varieties. That means that some of our stuff is fruity tasting and some can taste a little spicier. I'm all about figuring out ways to complement these flavors instead of trying to hide them or cover them up. Artichoke Dip is one of my favorites for complimenting a dank/spicy flavored strain while adding fruity strains to green smoothies and berry shakes is the way to go.
If you, like me, don't mind or weirdly enjoy the taste of your weed oil, skip this whole process and get right to baking!
But my world is expanding these days and it's not really about my personal preference anymore. I realize that most folks are at the mercy of someone else to provide god-knows-what-it-is in a bag, and I remember how bad some of that stuff tasted.
I also started baking for the elderly recently, which is so rewarding and fun. Since providing end-of-life pain relief has become a newfound love, making edibles more palatable and downright joy-mongering has also come into the forefront of how I make weed food. Change is good.
Enter… The Weed Wash
I'm not talking about actually washing your weed (although that is a thing I guess).
The Weed Wash is a technique you can use after you make your oil. It helps remove chlorophyll and other compounds that cause the “green” taste in your green oil.
Do not mistake this for adding water to your oil during the extraction process. (If you're considering doing this, just don't.)
I got lured into using this technique when I first started working on Wake & Bake, and made several batches adding water to my oil and mix. At first, I was like “AWESOME! Look at all of the black weirdness that the water is getting out of the oil. The water looked like a straight-up black lagoon and I figured it was pulling out “impurities” and leaving the oil with better flavor.
Soon after, I realized my oil wasn't storing as well and I noticed that the consistency was kind of gummy. The potency wasn't on par with the oil I had in the freezer (same trim, no water during extraction).
On Bad Kat's Canna Pharm, she has a great article about why adding water to your oil during the extraction process is lame with a capital L. I won't go into too much detail, because she's got it covered, but here are a few key points that may help you understand why adding water while extracting is no bueno:
The water is not responsible for stripping the components you want: it only pulls excessive salt, chlorophyll and other inert properties into the mix, while at the same time hindering the oil and its ability to break down your cannabis glandular material.
Besides external contact interfering, the inert plant matter soaks up additional water via passive capillary action before it can absorb the oil, and overall prevents the oil from gaining as solid access and contact as it otherwise would have, ultimately preventing the oil that you're relying on, to perform the extraction, from doing the job or making the progress that it otherwise could.
This leads to extended cooking requirements, including the 24-hour to several-day-long canna butter and oil recipes of the past, causing your cannabis to undergo unneeded degradation and excessive heat exposure.
Besides making a butter or oil with a reduced bioavailability when water is allowed in the oil or butter too early, and besides pulling in all the extra salts and waxes and chlorophyll that a pure oil wouldn't…. that waste water you toss out at the end, if you check the bottom, after it's settled?
You will notice a hash sediment.
[…] So many people, especially with the brief heating times recommended for water-butters these days, unwittingly pour out the equivalent of hash almost every single time they make canna butter!
Why Add Water AFTER Extraction?
I was skeptical after my first water/oil experience, but I saw that BadKat and a few others recommended it on a forum, and since I was making a batch of cookies for a 90-year-old man, I figured it would be a great time to test the technique.
Here were my results…
After Zero Weed Washes
After whipping up a batch of oil in the MB machine, I split the oil in half so I could have a control for this experiment. This batch was right out of the machine, no water added.
Scent: Delightful to me, but strong.
Flavor: Nutty, and distinctly weed-y.
Texture: Solid, like regular coconut oil at room temp. A bit of dark particle sediment on the bottom.
After One Weed Wash
I melted the canna oil down and added room temperature/cold-ish water and put it in the fridge overnight. When I woke up, I cut the oil that had risen to the top and removed it from the container. There were oil chunks floating around and the water had turned a light green-golden color. It seems like you lose some oil while doing this, but the difference in the smell and taste was pretty incredible.
Scent: Mildly weedy.
Flavor: Light, and still nutty.
Texture: Still solid, like regular coconut oil at room temp, but the dark Particle sediment on the bottom was nowhere in sight.
After Two Weed Washes
In hindsight, this is where I would stop. As you'll see in the next wash, the oil seemed to get somewhat waterlogged, but that could have been because I got pressed for time and put it in the freezer for a few hours. Still, this batch was perfect and I think it's worth the time and effort up until this point. After this wash, the oil was perfect for whipping up and had the faintest weed taste and smell. It was really nice.
Scent: Faintly weedy.
Flavor: Light and tasty.
Texture: Creamy and light. It seemed like it would have made a great whipped spread, but I'll have to try that the next time I stop at this many washes.
After Three Weed Washes (overkill)
At this point, I was ready to get baking, so I did the last wash and tossed it in the freezer. The oil got waterlogged and when I was baking with it, I had to let the water drip out on several occasions. It didn't change much flavor or scent wise, but the water still turned colors a bit, so I'm guessing that something was still happening.
Scent: Lightly weedy. Not noticeable at all until your nose was right up on it.
Flavor: Light with a tiny bit of a weedy after taste.
Texture: Waterlogged, which I think was due to rushing it into the freezer. Other than that, once I got most of the water , it creamed up with sugar for cookies very nicely.
Weed Wash: the Summary
From my experience, if you're trying to improve the flavor of your canna oil without destroying potency or the cannabinoid profile, doing a post-extraction wash or two can be a valuable use of your time. However, the more you mess with your oil, the more chances you have to do something weird to it (see Weed Wash #3), so it may be a little much to keep washing your canna oil, especially if it doesn't taste awful.
If your canna oil does taste awful no matter how many washes you do, let that serve as a reminder to lobby against the criminalization of cannabis in your state or nation. Better laws mean better weed 😉
