How to Decarb Cannabis by Sous Vide

Before making any cannabis edible, you must “decarb” the flower. What does that mean? Cannabis doesn’t actually produce THC; it produces an acidic cannabinoid known as THCA which needs to be activated through heat before producing THC. So, the first step is activating the cannabis through heat, like you would if you were smoking or vaping. Failing to do so will leave you with an inactive product that won’t give you the desired effects.

We have shown you the common method of debcarbing via the oven, which we shared on our Instagram (it’s saved in our “Recipes” Highlight), but wanted to try out something different!

Sous-vide, also known as low temperature long time cooking, is a method of cooking in which food is placed in a plastic pouch or a glass jar and cooked in a water bath for longer than usual cooking times at an accurately regulated temperature. Given the method’s precise nature and low temperate, sous vide is a fool-proof  way of decarbing your cannabis. For those that don’t enjoy their home smelling of cannabis after cooking it off in the oven (it can linger and be quite pungent!), the sous vide method has virtually no odor!

What you need

  • Immersion circulator
  • Container for immersion circulator (a large pot or plastic tub would work)
  • Vacuum sealer or zip-top freezer bag
  • Cannabis

  1. Prepare your water bath by filling your container with hot tap water, then place the immersion circulator inside. Make sure to follow the manufacturer’s guidelines to ensure the right amount of water is in the container. Set the immersion circulator to 203 degrees Fahrenheit.
  2. Grind the cannabis finely. Since the temperature will be so precise, there is no need to worry about overheating the cannabis and destroying THC, terpenes, or flavour. You do, however, want to maximize surface area, so a finer grind is the best for this method.
  3. In a vacuum sealer or, using the water displacement method* in a zip-top plastic bag, seal the cannabis as flat and as tight as possible to minimize air pockets and maximize surface area.
  4. Place the sealed cannabis bag into the water bath for 90 minutes, then carefully remove and let it cool to room temperature for 15-20 minutes. Dry off the bag carefully, open it and place your decarboxylated cannabis into a container for future cooking.
