What’s a Weed Grinder?
A weed grinder is a small device that grinds up your herb.
They vary in material, number of compartments and functionality.
One of the biggest selling point to owning a weed grinder is how much better they make your smoke.
Using a grinder to break up your herbs makes it easier to roll joints or blunts and even makes bowls smoke smoother.
But that’s not even the best part of using a grinder.
They actually make your bud more potent!
When you grind your buds with your fingers, the THC breaks off and sticks to you.
You notice how your fingers get sticky, right?
Well, any THC that’s sticking to you is THC that's not going to be on your cannabis when you smoke it.
How Many Compartments do I Need?
Technically, you only need one compartment.
But going with a single compartment grinder does a huge disservice to a grinders advantages.
You need multiple compartments if you want not only to smoke weed that’s been ground to perfection, but you want that third chamber catching your kief!
It’s literally free weed, and the best part is it’s almost nothing but the good stuff—THC!
- One Chamber
Weed grinders with one compartment are two piece grinders and are very much as basic as a grinder gets.
The two pieces are held together with a magnet and to use it you just open it, put your bud in and twist away.
After a few good twists, you open it up and shake the buds out.
The problem with these is the kief just ends up coagulating around the teeth and becomes pretty much useless since it’s damn near impossible to scrape it from the teeth.
These kind of grinders just aren’t worth it.
- Two Chambers
Dual chamber grinders come in three pieces (seeing a pattern?) and are a big step up from single compartment grinders, but still not good enough.
The second compartment is an open space just beneath the grinders teeth were the ground up bud falls.
Again, it’s a step up but you if you want the best weed grinder you need a four piece.
- Three Chambers
Grinders with three compartments allow you to catch kief, which is the best part of a grinder!
The first chamber is where you put your unbroken up bud, the ground bud falls into the second chamber, and the then the kief falls through a very fine screen and settles in the bottom chamber.
Now I’ll get into the best grinder brands in just a bit, but I don’t recommend any grinders that aren’t four piece grinders.
Which is the Best Material?
All of the grinders I recommend are metal, but you should know all the options you have.
Most of the grinders you’ll come across will be made of aluminum, but that’s not your only option.
And, to be honest, I recommend you don’t stray away from the norm on this one.
Metal grinders last longer, are of a higher-quality and are easier to clean.
As with anything plastic, it’s usually crap.
That may be a little too harsh, but they just don’t last as long and are prone to dings and cracks.
Plus, you have to worry about pieces of plastic making their way into your cannabis, no thank you.
They do grind up your buds well enough, and if you have a choice between no grinder and a plastic one, I’d go plastic.
Wood grinders are all right.
Don’t get me wrong; they actually look pretty cool.
But I have only ever seen them come in single compartment grinders, and they are treated more like a gimmick with marijuana leaves carved in them and what not than a good grinder.
There are other kinds of models like crank grinders and electric grinders, but I’m not even going to bother going into them.
Neither are suitable for cannabis, coffee maybe but cannabis no.
Why you need your Weed Grinder to Have a Badass Magnet
A weed grinder with a janky magnet is just asking for a bad time.
Once you start getting multiple chambers in a grinder the second and third chambers are always attached to one another with threading that you twist on and off.
But the top compartment is always held together with a magnet.
A weak magnet can cause the top to fall off of your grinder without you knowing.
Not only can this make the top piece walk off, effectively making your grinder useless, but you can also spill your bud all over the place if this happens in your car or pocket!
Moral of the story, don’t buy a weed grinder that doesn’t have an excellent magnet!
How to use a Weed Grinder
Most smokers are familiar with how a grinder works, but we all start somewhere, right?
Since two piece, three piece and four piece grinders all grind marijuana the same, I’ll give you instructions on how to grind weed using a four piece.
Or, if you prefer, you can watch the video below of Stoner Mom walking you through the process.
How to Grind Weed with a Grinder:
- Take the top off the grinder.
- Place a nug or two on top of the grinder's teeth. Be careful not to overfill the grinder, or you won't be able to twist it.
- Next, put the top back and turn it till you stop feeling a lot of resistance.
- Now, unscrew the middle chamber, and you’ll find your freshly ground bud.
How to Collect and Use Kief
That last pro tip gave you an actionable tip to collecting kief, but is there more?
And once we have a bunch of kief, what do we even do with it?
If you didn’t watch the video above here are the steps to collecting more kief out of your grinder.
- You need to have been using your grinder for awhile, and there needs to be noticeable gunky build up.
- Make sure there is no bud in the middle chamber. If you do have bud in there, this method will grind up the plant matter to powder diluting the quality of your kief.
- Place a coin in the middle chamber of your grinder and close your grinder up.
- Next, put the grinder in your freezer for about 30 minutes.
- Take the grinder out and immediately begin shaking the grinder and slapping the top of it with your palm trying to make sure all the kief goes to the bottom chamber.
- After a good 20-30 seconds of shaking, open up the middle chamber and scrape the sides a little bit and knock on the screen with the coin a couple of times.
- Finally, remove the kief catcher and check out all your kief!
The reason this works is the frozen trichomes easily fall off the sides of your grinder and down into the kief catcher.
If you’re running short on time, you can wrap your grinder in a wet paper towel and cut the freezing process to around 5 minutes.
Once you have a good amount of kief, you can load it all in one bong rip or sprinkle it on your blunt!
How to Clean a Weed Grinder
Cleaning a weed grinder is no different than cleaning a bong or pipe.
Of course, you want to make sure you’ve removed any bud and kief from your grinder before you clean it, and once that’s done gather up a zip lock baggie and some rubbing alcohol.
Unscrew all the grinders chambers and place them in the bag.
Next, fill the bag up with enough alcohol, so the grinder parts are all completely submerged.
Shake it around and then let it sit for awhile before removing the piece and rinsing them with warm water.
If you have any stubborn spots, you can use a toothbrush to work them out.
It’s a good idea to keep your grinder clean so that you can collect the most kief and that it keeps breaking up your bud well.
If you let it get too gunky, the screen will clog up, and the teeth will get sticky making it hard to twist your grinder.
The MacDaddy of weed grinders, The Space Case Herb Grinder.
Known for its quality, you’ll be getting a top of the line grinder that will last you for years.
It’s a huge grinder coming in at 3.5” in diameter and 2.5” high, and, of course, it’s a four piece grinder that even comes with a kief scraper making it easier to load on your bowl.
Its teeth tear through bud, and its screen doesn’t clog easily while still allowing only THC to fall through keeping plant matter in the middle chamber.
The way it grinds bud also makes this the best herb grinder for vaporizers.
The neodymium magnet is strong as heck.
Plus, it’s made in the USA out of aircraft grade aluminum!
In other words, you can expect this grinder to last for 10 years!
You’ll love the smooth twist of this grinder—it's so smooth, you almost won’t think bud's in it!
One thing that stands out about this grinder is the threads.
You don’t have to worry about cross threading like you do with cheap knockoffs.
And did I say this thing was huge?
You can easily grind 4 or 5 grams in this grinder!
This is a perfect grinder, the only downside being the cost.
Top of the line quality requires top of the line cost when it comes to weed grinders!
Another big dog in the grinder game is Santa Cruz.
None of their products disappoint, and they go toe to toe with a Space Case grinder.
The reason I give a slight edge to Space Case is the kief screen, and I like my bud ground up finely.
The Shredder leaves bud much more course.
You can get finer bud by grinding with the grinder flipped upside down so that it continues to get worked over by the teeth before falling into the middle chamber, but I’d prefer not to have to do that!
What’s cool about buying a Santa Cruz is you get a pollen crusher with it.
You pour all of your kief in it and press it into a little puck that’s easier to smoke.
The grinder uses a seven catch thread that prevents it from cross-threading, which is one of the biggest perks of investing in a quality grinder.
I wish they didn’t make the kief screen quite so fine, though.
Kannastor makes a damn good weed grinder.
I only wish they’d get more recognition.
It stands out from the pack by offering a huge storage chamber allowing you to carry around ground up bud with you anywhere.
If you accidentally pop a hole in your kief screen with most other brands, you’re out of luck!
But with Kannastors you can buy replacement screens should the need arise.
And the magnet is super strong with this grinder!
The holes beneath the teeth are perfect, too.
Just the right size to leave the bud with no chunks without turning your weed into powder.
I think we can all agree that bud sure is damn good to look at.
The see through middle chamber giving you a view of your bud is a nice touch.
Not to mention that, thanks to its perfect screen, this is one of the best grinders for kief.
Stoners love Golden Gate grinders.
They are incredibly strong, durable and they feel good in your hand.
Made from aircraft grade aluminum, this grinder tears your buds up.
It's diamond cutting teeth make twisting this grinder smooth as it gets.
The magnet is amazing and helps keep the grinder closed tight helping to control the odor.
The black paint is also scratch resistant and flake free, so you don’t have to worry about it chipping off into your buds.
The kief scraper this grinder comes with is fit to perfectly scrape the kief out out your grinder and into your bowl.
I wish the grinder felt a little heavier, I know this sounds weird, but it feels very light.
I also would love to be able to buy this grinder in a larger size.
At only 2.5 inches it's the smallest on our list so far.
Black Tie is trying to do what a lot of grinder companies can’t do—offer a premium grinder without the premium cost.
Now, it does fall well short of the Space Case and the Santa Cruz, but this grinder does not disappoint.
50 diamond shaped teeth sitting on top of well-sized holes make for an almost perfect grind every time.
They pay attention to the smoker's needs at Black Tie.
The kief chamber is perfectly smooth, and the sides have been rounded out making it a breeze to recover every spec of kief you collect.
It’s made from anodized aluminum, so you don’t have to worry about paint chips ever getting in your buds.
They also go the extra mile giving you a carry pouch, reinforcement of the pollen screen and two pollen scrapers.
The kief screen has a micron rating of 400, which is perfect for collecting kief.
The only issue you’ll have with this grinder is if you prefer to vape your bud it doesn’t grind the weed up fine enough.
I know you probably didn’t think that you’d see a grinder card on this list, but I have to give this guy some credit.
These things are awesome, especially for the traveling smoker!
They are the size of a credit card, so it fits perfectly in your wallet, and actually grinds your buds up pretty well—way better than your fingers at least.
To use them all you do is place a nug on the table and run this card over the bud just like a cheese grater.
If you’re traveling with it, just rinse it off with some warm water and soap or rub it with some alcohol before putting it back in your wallet.
A cool feature of the Raw Grinder Card compared to others is the three hole sizes allowing you to grind your buds to various sizes.
If you don’t have the cash to invest in a premium grinder, you should look into picking up a platinum.
They come with a lower price point, but still hold their own in terms of quality.
Made from aircraft grade aluminum this grinder has 49 diamond sharped teeth that rip your buds to shreds give a perfect grind every time.
It’s a normal sized grinder—2.5” in diameter.
The magnet is good, and the kief screen is good at only letting kief pass through it.
I will say this, though, don’t buy this grinder if you don’t like your bud ground up extremely fine.
It can be a little hard to pick your bud up from the grinder screen it’s so fine.
If you like the look of the Kannastor Grinder, but it’s a little bit more than you wanted to spend, Zip Grinders are a good alternative.
Standing at 2.5” wide and 3.5” tall this is a decent sized grinder.
It’s huge, the transparent middle chamber can hold up to a quarter, and the magnet is good enough to feel confident storing them in there for a long time.
This grinder is smooth and fast, and it feels nice in your hands when you're twisting up buds.
Everything about this grinder works extremely well, but once you have it in your hands compared to the Kannastor, you can feel the quality difference.
Ahh, the cute little Chromium Crusher.
This made the list because it’s the best for the money, as in, it doesn’t cost a lot of it.
Even though it’s so cheap, it’s a pretty sturdy grinder that grinds your buds pretty damn well.
Chromium wants to be the most affordable grinder on the market, to make it at such a small price point you do have to give up a little bit.
This little grinder is only 1.6" in diameter and 1.75" tall, and it can only fit about a gram to a gram and a half—coincidentally the perfect amount for a blunt 😉
I do wish that the inside of the grinder wasn’t coated.
This makes me worry that over time it could chip off into your bud.
Be sure to clean it well every now and then and keep an eye out for paint chipping off the teeth.
The Golden Bell is another grinder with a good small price to high-quality ratio.
It stands a little bigger than the Chromium Crusher (2” compared to 1.6”).
So, naturally, you’ll be able to fit a bit more bud in it.
It comes with a kief scraper, and the screen is good at keeping plant matter out of your kief catcher.
It has a Poly-O ring designed to help reduce friction when you’re grinding, keeping the experience smooth.
The biggest knock against the Golden Bell is its magnet is one of the weaker ones, and the lid wants to jump off sometimes.
You can’t go wrong with any grinder from one of the best grinder brands.
And stick with a four piece grinder to get the most a grinder has to offer.
