Grinders
by Storz & Bickel
The Storz & Bickel Herb Mill is a lightweight plastic herb grinder with extra-sharp teeth designed to produce a fine, even grind — exactly what you need for proper vaporiser performance. Built by the same German engineers behind the Volcano and Mighty vaporisers, this affordable grinder punches well above its price point. It's simple, it works, and it fits in your pocket. If you're looking to buy a herb grinder that pairs perfectly with a quality vaporiser, this is the one Storz & Bickel themselves recommend.
A properly ground herb increases vapour extraction efficiency by up to 30% compared to hand-torn material, according to vaporiser performance testing by Storz & Bickel. We've watched customers spend serious money on a Mighty or a Volcano, then tear their herbs apart by hand and wonder why the vapour is thin and uneven. The answer is almost always grind consistency. Finely ground herb means more surface area exposed to heat, which means better extraction, fuller flavour, and less waste. A 2019 study published by the Beckley Foundation noted that controlled heating of evenly ground botanical material produces significantly more consistent compound release than uneven preparations.
The Storz & Bickel Herb Mill was designed specifically with their vaporisers in mind. The tooth geometry produces a grind that's fine enough for conduction and convection chambers without turning everything to dust. You get airflow. You get even heating. You get the session you paid for when you bought the vaporiser in the first place.
Now, here's the honest bit: this is a plastic grinder. It's not going to feel like a machined aluminium four-piece in your hand. It weighs roughly 15 grams — about the same as three coins. That's not a flaw, though. It means you can toss it in a bag, keep one in your jacket, or stash one with each vaporiser without thinking twice. The teeth stay sharp for a good long while, but if you're grinding daily for months on end, an aluminium grinder will outlast it. For the price, though, we'd grab two of these before spending four times as much on a metal one we're scared to scratch.
Using the Herb Mill takes under 30 seconds from start to finish — roughly 8 to 12 twists is all you need for a fine, vaporiser-ready grind.
The Storz & Bickel Herb Mill is a 2-piece plastic grinder measuring approximately 55 mm in diameter, weighing around 15 grams.

Already own a Storz & Bickel vaporiser? The Herb Mill was made to pair with the Mighty, Crafty, and Volcano filling chambers. If you're building a complete portable setup, consider the Storz & Bickel Dosing Capsule Set — it keeps your ground herb pre-loaded and your chamber clean between sessions. For storage, the Miron Violet Glass Jar blocks over 90% of visible light to keep freshly ground herb from drying out. And if you're still deciding which vaporiser to order, the Mighty Vaporiser by Storz & Bickel remains our most recommended portable unit since 2014. Browse the Azarius vaporiser category or the herb grinder collection for more options.
Over 25 years and thousands of Storz & Bickel vaporisers sold since we opened in 1999, the number one follow-up question is always the same: "Why doesn't my vapour taste as good as the one in the shop?" Nine times out of ten, it's the grind. Hand-torn herb leaves air gaps in the chamber. Some bits combust while others barely heat up. A proper grinder addresses that problem in about 5 seconds — more surface area means more even heat distribution, which is basic thermodynamics rather than marketing.
The Herb Mill is the grinder Storz & Bickel themselves include in their starter recommendations. That tells you something. It's not fancy — no kief screen, no magnetic lid, no anodised colour options. It's a 2-piece plastic grinder that does exactly one thing and does it well: it turns herb into a fine, consistent grind that fills a vaporiser chamber evenly. We keep a couple behind the counter for exactly this reason. When someone walks in with a brand-new Mighty and no grinder, this is what we hand them. According to EMCDDA guidance on harm reduction, using a vaporiser at controlled temperatures with evenly prepared material is considered a lower-risk method of consumption compared to combustion — and grind quality is a key variable in that equation.
The one honest limitation to watch: don't grind wet or sticky herb in any plastic grinder. Let it dry out slightly first — ideally to around 10–12% moisture content — or you'll spend more time cleaning than grinding. A quick brush after each use keeps the teeth clear and the grind consistent session after session. If you need a grinder that handles stickier material without complaint, an aluminium model like the Black Leaf Grinder is a better fit for that specific job.
No. The fine grind it produces works brilliantly in any vaporiser, and it's just as good for rolling or packing a bowl. Storz & Bickel designed the tooth geometry with their own chambers in mind, but ground herb is ground herb — it's not locked to one brand.
For grind quality, yes — the S&B Herb Mill produces a consistently fine result. Where metal grinders pull ahead is long-term durability and kief collection. If you don't care about collecting kief and you're not grinding 5 times a day, plastic handles the job without issue.
Ground herb has more surface area exposed to heat, which means more even extraction in a vaporiser or more consistent burning in a roll-up. Hand-torn pieces are uneven — some bits overheat while others barely get warm. A grinder gives you a uniform particle size in seconds.
Tap it out after each use and brush the teeth with a dry toothbrush or small cleaning brush. For a deeper clean, soak both pieces in warm water with a drop of washing-up liquid, scrub gently, and let them air dry completely before the next use.
Fine enough for conduction and convection vaporiser chambers — that's the sweet spot. It's not a powder grind; it's a consistent, fluffy texture that allows good airflow through a packed chamber. Exactly what you want for full extraction without clogging.
An unused, clean grinder is generally fine in carry-on or checked luggage. If it has any residue on it, that's a different story — clean it thoroughly or leave it at home. Airport security cares about residue, not the grinder itself.
With regular use — a few sessions a week — the extra-sharp teeth on the Herb Mill hold up for 6 to 12 months. Heavy daily users may notice a slight dulling over time, but at this price point, replacing it is painless. Order a spare to keep on hand if you rely on it daily.
You can buy the Storz & Bickel Herb Mill directly from Azarius. We ship from Amsterdam and have stocked Storz & Bickel products since 2003. Get yours alongside any vaporiser order for the best session from day one.
