What’s the Best Way to Decarb Kief?

After smoking your cannabis flower for a couple of months, you may start to notice a buildup of kief in your grinder’s kief catcher. There are countless ways to utilize your stored-up kief, and you should, in fact, use it! Kief is highly concentrated with cannabinoids, making it more potent than the rest of the cannabis plant.

Because of its potency, kief can be used in various ways. You can incorporate it into recipes for cooking, infuse it into oils or butter, or simply sprinkle a little bit on top of a bowl or joint for an added kick.

What Does Decarbing Kief Do?

In its raw form, kief contains THCA (tetrahydrocannabinolic acid), which is not psychoactive. However, by applying heat, THCA will convert into THC in a process called “decarbing” kief. Kief decarboxylation is essential if you plan to consume your kief in a way that involves activating the cannabinoids, so here is a summary of the best way to decarb kief at home.

Do You Have to Decarb Kief?

It depends. You need to heat up the kief to a certain temperature if you want to activate its THC. Without the decarbing process, the cannabinoids won’t be effective when consumed in edibles, tinctures, or other cannabis-infused products.

However, if you're smoking or vaping kief on its own or mixed with cannabis flower, decarbing may not be necessary. When you smoke or vape, the heat from the flame or vaporizer is sufficient to decarboxylate the kief, activating the THC and making it effective.

How to Decarb Kief

The best way to decarb kief at home is with a run-of-the-mill conventional oven.

1. Start by preheating the oven at a low temperature to ensure that you activate the cannabinoids without burning them.
2. Prepare the kief by spreading it evenly on any oven-safe cookware. For the best results, first try spreading the kief into a very thin layer on a piece of baking paper and wrapping it in foil.
3. Next, begin the decarbing process by putting the baking sheet with the kief into the oven. Make sure to check on it occasionally to make sure the kief doesn't overheat or burn.
4. After about a half hour, remove the container of kief from the oven and let it cool.

If done properly, decarbing your kief in the oven will boost your kief’s psychoactive properties and prepare it for any kind of cooking or baking.

What Temperature Do You Decarb Kief?

If you’re decarbing your kief at home, try to preheat the oven to about 250°F. Keep in mind that if the temperature is too high, you might burn your kief and ruin the entire batch. That’s why it’s better to heat your kief slowly at a low temperature. If you smell burning or see a lot of smoke coming out of the oven, consider lowering the temperature 5-10°F.

How Long Do You Decarb Kief For?

When decarbing kief in the oven, you’ll usually want to heat it for about 30-40 minutes. Removing the kief too early can ruin the batch, as it's essential to ensure that the THCA has been converted into THC. On the other hand, if you decarb the kief for too long, you risk overheating and potentially degrading the cannabinoids and terpenes. If you’re not sure how long to decarb kief for, feel free to check on it every 5 minutes or so.

During the heating process, kief sometimes changes color from a light green to a medium brown. Furthermore, the smell of decarbed kief may start to become more potent after about a half hour. These are both great indicators that the decarboxylation process has completed.

Do You Have to Decarb Kief for Brownies?

Yes. If you want to make brownies or any other cannabis-infused edibles with kief, it's necessary to decarb the kief first. One method to use kief for edibles is to decarb your kief in an oven and mix it in with butter or oil to make cannabutter or cannabis oil. You can follow our guide to make cannabis-infused butters and oils, or you can try making your own.

The Effects of Kief

When decarbed properly, smoking kief can produce a more intense and potent experience compared to smoking regular cannabis flower, due to its higher concentration of THC. The high is typically more euphoric, relaxing, and powerful, which can be overwhelming for beginners or those with a low tolerance. Because of its potency, a small amount of kief can go a long way. 

Remind yourself that when cooking or preparing non-smokable cannabis products, decarbing is a key step to ensure you get the full effects of the cannabinoids in your kief. But, if you're smoking or vaping your kief, the heat from the process naturally decarbs the cannabinoids, so decarbing separately may not be necessary.
