To help you choose the best herb grinder, we tried out all of the top products, testing them for reliable grinds, with options for choosing the thickness of a grind, and sturdy enclosures, often with magnetic lids to stop ingredients from escaping. We also preferred light and portable products. Additionally, if a grinder uses a built-in battery instead of a manual design, we looked for the maximum amount of grinds per charge, with nothing lower than 120 grinds per charge. And, if you’ll be using these ground herbs to make liquid vape juice, then you need to read our best vapes guide.

The best herb grinder that we tried was easily the Tectonic9 Herb Grinder, which uses a motor to automatically dispense the herb, activated by pressing a button, and features a flip spout which is extremely handy, and boasting a light form factor, which makes it truly portable. The powerful 320mah battery lets you dispense over 120 times before needing to charge and the innards are lit via LED lights, so you can check on ingredients mid-grind.

The one-button manual functionality is great for making minute thickness adjustments and the inside is lit with some LEDs, so you can check in on the ingredients. We also liked the auto dispenser, which simplified the entire experience.

This is a high quality product, with ultra-sharp CNC manufactured grinding blades combined with the auto dispensing technology, so the price is higher than many other items on this list. Additionally, while we found the manual one-button dispensing to be superb, some users may prefer the traditional process of opening up the grinder, so as to eliminate the need for electronic components.

We’re sorry, this product is temporarily out of stock

Award: Honorable Mention

WHY WE LIKE IT: Available in two sizes, the larger being 4 inches wide, and a wide variety of color choices, suiting just about any aesthetic, with a magnetic lid that helps reduce spillage. This is a fantastic and simple-to-use grinder with the option for an extremely large loading space, at four inches.

It comes in two sizes, 2.5 inches and 4 inches, with the latter boasting plenty of room for large amounts of ingredients. The multitude of color choices are cool and the price is on the lower side.

While we enjoyed the simple twist design for its simplicity, some users may prefer an actual motor and electronic components, like our top pick. Additionally, between the mesh strainer and the multiple components that make up this grinder, it can be somewhat tough to clean adequately, which you should do before using the first time, as we had some aluminum shavings inside, likely from the manufacturing process. The Cali Crusher Homegrown 4 Piece Grinder is another great option with dual action radial cut teeth to turn your herbs into a fine grind. Also, check out the best digital pocket scale.

  • Ultra durable
  • Low price point
  • Comes with multiple mesh screens and pollen scraper
  • 2 inches wide, so can’t fit too much
  • Twist design not for everyone

It comes with a multitude of accessories, including multiple mesh screens and a pollen scraper, and we found the simple twist design allowed for effortless grinds. The lifetime warranty is also fantastic, and is tied for the highest warranty on this list.

We did find that this grinder needed herbs to be really dry, as wet ingredients tended to get stuck in the blades. Additionally, it is only two inches wide, so there isn’t much room to stuff ingredients into the loading space. Another handy gadget to have is the best spray bottle.

 #4  Kannastör GR8TR V2 Grinder

We’re sorry, this product is temporarily out of stock

Award: Most Thickness Options

WHY WE LIKE IT: Comes with a series of interchangeable plates, which adjust the thickness of the grind, and boasts a completely modular design, which allows you to remove unneeded components, to enhance simplicity and portability.

  • Modular Design
  • Contoured edges, for ingredient removal

  • Twist design not for everyone

The Kannastör GR8TR V2 Grinder is a well made product, with components made from stainless steel, and coming with a series of interchangeable plates, which allow users to easily decide the thickness of the grind. The contoured edges makes removing ingredients extremely easy, and stops gunk from getting stuck, and the modular design is extremely innovative, allowing the product to still function after removing extraneous components.

This model features a simple twist design in line with many other of our picks, but is nearly as expensive as our top pick, which comes with a battery and other tech-forward accoutrements. Additionally, the loading area is only 2.2 inches wide, meaning you’ll have to do large amounts of ingredients in batches. Check out the Space Case grinders too, which have sharp teeth for precise and even cuts. If you prefer to chop your herbs, the best knife brands will help.

The scratch-resistant black matte finish looks great and the lifetime warranty is spectacular, tied for being the longest warranty available on this list. Check out one of the best online vape stores if you’re looking for a more discrete way to smoke on the go.

Though the width of this product, at 2.5 inches, is decent and in line with several other items on this list, we couldn’t help but wish we had more room for ingredients, as we had to do some herbs in batches. Additionally, we found it pretty easy to accidentally overtighten the enclosures, making opening them afterwards a chore. Another option with a magnetic lid and mesh screen is the Santa Cruz Shredder, which is one of the best weed grinders on the market today. You may also like the best air fryer for the kitchen.

  • Lightweight & durable
  • Sturdy magnetic enclosure
  • Pollen scraper included
  • 2.5” is decent, but number two pick has an option for 4”
  • Can grind ingredients too finely
  • Large white logo on top may not fit all aesthetics

The Platinum Grinders Herb Grinder with Pollen Catcher comes in at a relatively low price point, while offering high end features in line with most of the other products on this list. It is extremely durable, manufactured using aircraft grade aluminum alloy, and the lid boasts an extremely sturdy magnetic enclosure, which helps avoid the accidental spilling of ingredients. It also comes with a pollen scraper, which is a nice bonus.

While the cutting teeth are extremely sharp, we found that they grinded ingredients really quickly, creating an ultra-fine grind before comparable products on this list, so adjust accordingly. Additionally, the large white logo that sits atop the product may not fit all aesthetics and seems a bit like an advertisement. Your kitchen also needs the best electric wine opener.

How We Decided

To help you find the best herb grinder for your kitchen ingredients, we tested out plenty of models for grinding consistency and speed, favoring both simple manual twist designs and electronic battery-powered designs, as in our top pick. We made sure all of the grinding teeth in the above products were of a high quality and contributed to even and reliable grinds. Also, read about kitchen appliances.

We also preferred grinders that allowed for thickness adjustments, which is done using a variety of methods. Simple twist design grinders allow for manual thickness adjustments. In other words, the more you twist, the finer the end result will be. Some products, like our number four pick, come with interchangeable plates, each intended to change the thickness of the ingredients.

We also awarded bonus points to products that came with useful accessories, such as multiple mesh screens and pollen scrapers, for the removal of ingredients that have gotten stuck to the side. Finally, we especially liked models made from highly durable materials, including stainless steel and aircraft grade aluminum alloy, both of which will ensure the grinder will remain functional for years to come.

Herb Grinder Buyer’s Guide

The Most Important Features to Consider

  1. Type of grind
    Herb grinders come in two basic varieties, those that feature the old school twist design that typifies the category and those with some kind of electronic motor. Twist designs are great because they are extremely simple to understand and to use, with no electronic components that can break over time. Those with a motor can be extremely useful as they often boast a much more uniform grind, taking some of the guesswork away from standard variants. Motor-based grinders are typically more expensive, however.
  2. Grind thickness
    Herb grinders allow for thickness adjustments in a variety of ways. Standard twist-style grinders are powered manually, by twisting, so you can adjust the thickness by twisting less or more, as per your desire. Some products, however, adjust thickness via interchangeable plates and motorized speed settings. If you are relatively uninterested in making minute thickness adjustments, any standard twist-style grinder will be fine. If you really want to control thickness variables, perhaps go with something that comes with a variety of different sized plates, like our number four pick.
  3. Accessories
    Many products come with useful accessories to make the grinding process more efficient, including pollen scrapers, which help to dislodge any ingredient remnants that become stuck in the corners or near the blades, and multiple mesh screens, which are used to separate the pre-ground ingredients from those that have already been ground. Magnetic enclosures are also useful, as they make sure the grinder is sealed tight when in use, so you won’t run into the accidental spillage of ingredients.

Herb Grinder FAQs

What is a pollen scraper?

Some of the above items come with accessories, such as a pollen scraper. A pollen scraper, essentially, is used to dislodge any ingredients that have become stuck to the corners of the grinder.

Can I use a coffee grinder to grind herbs?

In theory, yes, but maybe coffee grinds will pulverize fragile herbs, delivering a much finer grind than necessary for many recipes. These herb grinders allow for easy adjustments, which better suits the delicate nature of herbs.
