Making Cannabis Oil in a Mason Jar

mason jar cannabis oil
Thank you for supporting this site with purchases made through links in this article.

I just wrote a post about cannabis oil dosage that was inspired by new friend Luke’s question last week. When he got back to me, he brought up something I was totally over the moon about and wanted to share with you guys.

When I first started making crockpot cannabis oil, I really wanted it to be as simple as possible. I looked at every equation that wasn’t pot + oil  + crockpot = crockpot oil as frivolous and over the top. I read somewhere about someone putting water in a pan in the oven and filling mason jars with oil and cannabis and infusing them in a water bath and literally thought, “That is waaaaay too much work.”

But one day, after making oil a billion times the same way, I thought, “What if you put it in a mason jar?”

Boom! It was magic!

I still stuck to the crockpot method, and haven’t ventured into my oven, but I’ve been assured that that method works just fine.

Benefits of Mason Jar Cannabis Oil

There are quite a few benefits of making your oil in a mason jar. If I didn’t have a Magical Butter Machine, this would probably be my go-to method for oil. While I think that the MBM is the easiest way to make canna oil and butter, I believe that simple methods like this one still make cannabis oil that is just as potent and flavorful. I also understand that the MBM is an investment. If you make oils and infusions regularly, I highly recommend it. If you’re itching to upgrade and want to save a little cash, here’s a $25 off coupon code for the Magical Butter Machine that they gave me to pass on to you.

In the meantime, here are some reasons to use a mason jar for making your canna oil:

  • I don’t know about you, but my crockpot doesn’t boil water, even on high. This means that the temperature of the H20 stays below 212° F and that’s well below the boiling points for all of the major cannabinoids, terpenes and flavinoids. Keeping those compounds in tact is the best part of medicating using cannabis infused coconut oil and this method really allows you to maintain an ideal temperature.
  • Cleanup is much easier since you only have a jar, a bowl and a strainer to clean.
  • While it’s not completely smell proof, it does reduce the smell a ton.
  • You can make much smaller batches without worrying about ruining your oil.
  • You can set it, and even if you forget it, you wont burn or overcook your oil.

To Seal or Not to Seal

Luke wanted to reduce the smell by cooking his cannabis oil in the crock pot in a sealed Mason jar. He wanted to know if it would be okay to seal that baby up.

Yes! You can seal the jar to keep the smell under control. Check the method below and burp your jar at least once to make sure that the pressure isn’t building up.

Mason Jar Cannabis Oil or Butter Method

This is just an all around excellent and simple method. If you want to keep the smell under control or you want to make a small batch of oil, the mason jar is your new best friend. Just use the crockpot oil method, but instead of putting the oil and herb directly into the crockpot, do the following:

  1. Fill your crockpot about halfway with water (or just enough to cover the herb).
  2. Fill a mason jar with equal parts oil and cannabis. Cover with lid.
  3. Place the mason jar in the crockpot and put the crockpot on high.
  4. Burp the jar after about a half hour to make sure that there’s not too much pressure building up. If you get a lot of pressure on the first burp, make sure to burp the jar often.
  5. There’s absolutely no risk of overcooking this oil. The water in your crockpot might simmer, but probably wont boil (even on high), so feel free to leave it in there for as long as you’d like. Luke did it for 4 hours, and I’ve forgotten it purposefully did it for nearly 24 hours and it turned out just fine.
  6. Strain with cheesecloth (save for making High Chai).
  7. Store normally. Use oil in Cannabanana Bread or Artichoke Dip.

    yes cannabis oil methods are same in most of way but not so lengthy which depends on how much oil have been producing at a time, Mason Jar is the different way but process results are same, it follows on equal parameters..but method is nice thanks for it !

    Hi. I love this method. I have used it several times successfully. However on my latest time the jar cracked! The oil leaked into the water. The jar remained whole in the pot, but broke as I cleaned it out. I burped it once, but should have more regularly. I’d say to burp it once every two hours no matter what. I currently have the oil an water in the fridge, hopefully the oil will separate and I won’t have wasted it.

        I had used it a few times previously. Since then I burp it every hour or so and have not had a repeat of the problem. And yes, the oil did separate from the water. It didn’t have a nutty smell or taste, but it worked, so I won’t complain.

      I vape cannabis oil and you can vape as long as the oil is made with food grade alcohol. I wouldn’t vape cannabis oil with coconut oil iether, coconut oil isn’t good in lungs.

      Hi Leibel, wanted to share a recipe I use for chronic pain. I start with a mason jar and put my ground up bud in there. Decarb for 20-25 min at 220. Take the jar out of oven an let sit.. When the jar has cooled I will put in Coconut Oil. 2 tbsp. for every 1 gram. Put in the crockpot on high for one hour, I fill my pot and then put a bowl in there for mason jar to rest in, just so it never touches the bottom. After an hour turn down heat, burp jar, and put er in for another 11 hrs. I stir the jar ever few hours. So now your at the 12th hr. I take the jar out and let cool, but not too cool. I want to let the oil suck everything out. Strain into a sealable container or another mason jar, store in fridge and your good! I throw a spoonful in my coffee and my day is ready. I recently had my 5th spine surgery, and Docs are amazed I’m not taking a bunch of pills! Good Luck and God Bless!!

      Nothing but a plant based diet, would be recommended. I’m not a Dr or anything, but just giving my personal opinion. I suggest watching what in the health. It’s a fairly new documentary, and I found it intriguing with my extensive medical history/issues. Just trying to make a change for better. Hope it helps. There are actually several cancer patients who have converted to a solely plant based diet, non gmo, organic diet. No chemicals, no toxins, just healthy living. Tumeric, ginger, and several other essential spices, herbs, and essential oils have very powerful effects when it comes to helping the human body to be it’s best/most efficient. I could have this convo all day, but again, I’m no Dr. So, please don’t take my word for it. Do yourself one better, do the research hunny. I’m sure you will be astonished. I hope and pray everything works out. I’m just a mere human with tons of stuff I’m trying to fix for myself. Hope it helps hun.

    Thank you for the recipe!

    For clarification for myself & others: do you put the cover on the crock pot, too?

    When I did this without it, and with the crock pot set to high, the temp of the water in the crock pot/around the jar only reaches 140. If I cover it it goes over 200. If I set the lid on crooked I can get it at the desired temp of 160.
    I’m using an old Rival pot, probably 2-3 quart size if I had to guess.

    Looking forward to experimenting with the resulting oil 🙂

      I use the canning jar rings/lids, works great!! I don’t cover the jar with water I fill my Crock-Pit 2/3with water.

      Burping in just open the jar so it doesn’t seal. I have heard some had it blow. I don’t know tho, you would burn precious meds if it got that hot. I just made a batch an it’s absolutely amazing. I’m 2 months out of my 5 the spine surgery and kicking butt!! Be careful and only a tsp to begin.

      I didn’t cover the crockpot because my quart jar didn’t fit, but I’m not sure how it effected temperature stability. I’d say to stick a thermometer in it if you can and leave it uncovered. If it seems to go up and down, try covering it and see if it stays in the temperature range you’re trying to hit 🙂

      Hope that helps!

    Corrinne. I have a couple of tips for you. #1 would be to purchase a temp controller for your crock pot. I bought one off Amazon. Inkbird 308. Using an old crockpot, not a new fangled electronice one, you can dial in any desired temperature. I make my oil at 170 degrees. I don’t suffer the oil loss I did when I made it at 202 degrees. The second item would be a nut bag instead of cheesecloth. They are used to make almond milk. I also bought that off Amazon. It works much better than cheesecloth. I can really squeeze the oil out. They are washable and can be used over and over unlike cheesecloth.

    You can eliminate the burping issue by placing your mason jar lid on upside down. IE, the sealing ring UP. Then screw the ring on loosely. This prevents the jar from sealing and “burps” itself. Set it up before going to work in the morning and it can go all day unattended without mishap!!!

    I’m wondering about decarb specs for bubble… Do you think it would be necessary to decarb first before making this infusion? It’s hard for me to figure this out… I have done plenty of research on the topic, including reading your post about it, and it seems that proper decarb would not be achieved in 4 hours of simmering at 160 degrees… But I wouldn’t want to heat my hash at 240 degrees first for an hour if I don’t have to. What do you think.

    P.s. Thanks for all the awesome pages of information about cannabis infusions. It has been very knowledgable and is helping me out a lot. Cheers 🙂

    If you use the crock pot method do you still have to go through the decarboxylation process. Also, I’ve read where lower THC levels are better for women to achieve orgasms. If you’re making lube for your lady friend do you want high THC levels or low?
