If you smoke or vape flower, a weed grinder is one of your most trusted tools. Weed grinders are cherished by all who use them for their ability to quickly transform large, sticky cannabis flowers into a fine grind suitable for packing into bowls and rolling into joints.
With the rise of recreational cannabis, grinders have evolved into all manner of shapes, sizes, designs, and price ranges. There is even a growing number of sleek, modern, electric weed grinders, which automate the entire process. You can’t avoid getting your fingers dirty while still having consistently ground bud ready to consume using a quality grinder.
Grinders have come a long way since the early days of cannabis culture. The best weed grinders of 2021 borrow from the designs of the past but offer much more to the consumer.
What is a weed grinder?
A cannabis grinder is a tool designed to break down dried cannabis flower into smaller pieces, making it easier and smoother to smoke or vape.
Most weed grinders work by tearing apart cannabis between two sets of offset teeth in a small chamber. As you twist the grinder back and forth, the teeth crush and crumble the larger flower into finely ground pieces that fall into a collection chamber.
How much is a grinder for weed? Typically prices for weed grinders start around $5 for the most basic plastic designs. A metal grinder with specialized features costs between $40 to $100. Automatic grinders are the most expensive, usually well over $100.

What do you use a weed grinder for?
If you intend to smoke or vaporize cannabis, you need to break it down into a fine and fluffy consistency before packing it into a pipe or rolling it into a joint. This is when a weed grinder comes into play.
Although it’s possible to break apart cannabis with your fingers or a pair of scissors, grinders create a more consistent grind, which means a better smoke.
Weed grinders are a critical component for breaking cannabis into smaller pieces before smoking or vaping. Larger chunks of flower burn inconsistently, leaving leftovers in your bowl or ending up with a joint that burns down one side.
The perfect grind that you’ll achieve with a grinder helps encourage airflow in and around each small piece of flower. More oxygen means a better burn.
How to grind weed without a grinder
If you’ve misplaced your grinder or are waiting for your order to arrive, you can still achieve the perfect grind.
There are dozens of gimmicky ways to grind weed without a grinder, but the most straightforward approach is to use a pair of scissors. Tightly hold the flower between your thumb and forefinger, and use the scissors to cut through the bud.
You can also place the flower in a small shot glass while snipping to keep the small pieces contained.
Repeat until you reach the desired consistency. After you’re done cutting, remember to wipe the blades with isopropyl alcohol to remove the sticky resin.
For those looking to grind larger amounts of flower, a coffee (or spice) grinder can power through a substantial amount of bud within a few seconds. Fill the grinder with bud, and pulse the grinder until the flower is light and fluffy. Short pulses are key because continuous mechanical grinding will risk melting the trichomes.
Once again, clean the grinder well before and after use to avoid the flavours melding from one ingredient to the next.
How to clean a weed grinder
Eventually, every grinder needs cleaning to remove the sticky resin, which can gum up the works.
How often should you clean it out? The cleaning schedule will depend on the frequency of use. One way to tell it’s time to clean a manual grinder is when it starts to catch while twisting.
The best cleaning solution for most grinders made from metal, glass, and acrylic components is isopropyl alcohol.
- Unscrew each grinder component, including the top, flower catcher, and pollen trap, placing them together in a small bowl.
- Pour just enough isopropyl alcohol into the bowl to cover the components,
- Soak for 30 minutes.
- Remove each part from the solution, and use a piece of paper towel to wipe away any residue. Use an old toothbrush to get into the hard-to-reach areas.
- For any exceptionally grimy grinders, repeat the process.
- When you’ve removed as much of the buildup as possible, rinse clean with water and allow to dry completely.
If you have an automatic, electric, or wooden grinder, refer to the manufacturer’s instructions for cleaning. It may not be suitable to clean these specialized devices by soaking in isopropyl alcohol.
