Herb Grinder Collection | Buy Jar Grinders Online

Why Choose a Jar Grinder

A jar grinder works like a standard herb grinder, but the bottom chamber doubles as a storage jar instead of just a catch tray. Grind your herb, and it settles straight into a compartment built to hold it until your next session, so there's no separate stash container to carry or misplace.

Many jar grinders also come with a glass window on the storage compartment, letting you see how much herb you have left without opening the lid. It's a small feature, but a genuinely useful one if you like to keep an eye on your supply at a glance.

Compare Other Herb Grinder Styles

If you'd rather browse other grinder styles first, our wooden herb grinders and acrylic herb grinders collections cover the more traditional and budget-friendly ends of the range.

Our full herb grinders hub also lets you compare every style side by side.

How to Choose a Jar Grinder

Decide if you want a glass window. It lets you check consistency and supply without opening the lid.
Check the number of stages. More stages, typically 3 to 4 pieces, separate kief from ground herb. Simpler 2-piece designs are easier to clean.
Consider storage capacity. The jar itself is the storage compartment, so size it to how much herb you typically keep on hand.
Choose manual or electric. Hand-crank models are more portable, while electric versions do the grinding for you. Our electric grinder collection covers the motorized side if that's the direction you want to go.
Check the lid seal. A tight seal keeps your herb fresher for longer between uses.

For a lighter, more travel-friendly option without the storage jar, our mini grinders collection is worth a look, and our cool herb grinders range covers a broader mix of styles if you're still weighing your options.

Frequently Asked Questions

What's the benefit of a jar grinder over a regular grinder?

A jar grinder grinds and stores your herb in the same piece. Instead of grinding into a tray and moving the herb to a separate container, it settles directly into a built-in storage compartment, so you're left with one piece to carry instead of two.

Do jar grinders come with a glass window?

Some do. A glass window on the storage compartment lets you see how much herb is left without opening the lid, which is useful if you like to keep track of your supply at a glance. Not every jar grinder includes one, so check the product listing if this feature matters to you.

How many grinding stages should I look for?

It depends on what you want out of the grind. A 3 to 4-piece design with more stages separates kief from your ground herb as a bonus, while a simpler single or 2-piece design is quicker to clean and easier to maintain. Neither is objectively better; it comes down to how much you value the extra kief-collection step.

What is a Medtainer, and does Grasscity carry them?

A Medtainer is a combined grinder and airtight storage container made by a specific brand, similar in concept to the jar grinders on this page. Grasscity doesn't currently stock the Medtainer brand itself, but if that's the style you're after, our own jar grinder options offer a similar grind-and-store setup worth comparing.
