Making QWISO Hash Oil


QWISO hash oil is a very simple way to make a cannabis concentrate. QWISO stands for Quick Wash in Isopropyl alcohol, which is exactly how you make it. This QWISO method is simple, affordable, and there’s no minimum amount of cannabis needed to make it.

How to Make QWISO Hash Oil

QWISO Method FreezerBefore you can start making QWISO you’re going to need a few items:

  • Isopropyl Alcohol – At least 91%
  • Cannabis Buds, Stems, or Leaves
  • Mesh Screen
  • Mason Jar
  • Small Pyrex Dish
  • Medium Pyrex Dish

The first step to making QWISO is to put the isopropyl alcohol and cannabis in the freezer. Freezing makes for a purer end product but is not necessary.

To start extracting QWISO, put the cannabis buds, stems, or leaves in the mason jar. Breaking up the cannabis beforehand will allow more surface area to come into contact with the iso but you don’t want to grind it too fine or you may end up with little pieces in your end product.

Making QWISOThe next step is to pour the alcohol into the mason jar with the cannabis. The amount of time the alcohol is in contact with the cannabis is essential. The more time it’s in the jar the less potent your end product will be but the more you will get. Keep in mind that you can do this process multiple times with the same cannabis.

I like to do 4 washes of 20 seconds each. The first batch of QWISO will be the best and lightest in color and close to being a “QWISO Wax”.  As you do more washes it will get darker and taste harsher.

Straining QWISOAfter each wash, pour the alcohol solution from the jar into the small pyrex dish while straining out the cannabis with the mesh screen. To further refine it, you can filter it with an unbleached coffee filter or cheesecloth but you will lose some product into it.

Purging QWISO Hash Oil

Now that you have your QWISO solution, it’s time to purge it. You can just let it sit out in the open and wait for it to evaporate naturally but you’ll probably be waiting a day or two. That is why I like to put the small pyrex dish with the solution into a bigger one filled with hot water.

Using hot water instead of direct heat is important because you don’t want any cannabinoids to evaporate or an open flame to set the alcohol on fire.Purging QWISO

Once the QWISO is solid and can’t be lit on fire with a lighter, you can scrape it out of the dish with a razor blade and start smoking.
