How to Use a Grinder

A grinder is the least glamorous thing in your setup and one of the most useful. Here’s how to use one right — and what that bottom chamber is for.

Breaking up flower by hand works, but it’s messy, uneven, and wastes the good stuff on your fingers. A grinder fixes all three in about five seconds. If you’ve got one and aren’t sure you’re using it fully, this is for you.

The parts of a grinder

Most quality grinders have four pieces (people call them “4-piece grinders”):

1. The top lid with grinding teeth.
2. The grinding chamber — where you load the flower; the teeth do the work here.
3. A collection chamber below, separated by a mesh screen — ground flower falls through to here.
4. The kief chamber at the very bottom.

Two-piece grinders skip the screen and kief chamber — simpler, but you miss out on the best part (below).

How to use it

1. Load it. Break flower into a few smaller pieces and place them around the teeth — not dead center (that’s where the magnet sits).
2. Grind. Put the lid on and twist back and forth. Ten to fifteen turns is usually plenty. Don’t overdo it — over-grinding makes it too fine.
3. Open the collection chamber. Your evenly-ground flower is waiting, ready to pack a bowl or roll.

The kief chamber — the bonus

Here’s the payoff of a 4-piece: over time, the tiny, potent trichome crystals (kief) fall through the screen and collect at the bottom. It builds up slowly. Sprinkle it on top of a bowl for an extra kick, or save it up. That bottom compartment is basically a slow-filling reward — and the reason a 4-piece is worth it.

Keeping it working

• Clean it occasionally. Residue gums up the teeth and stiffens the twist. A little isopropyl alcohol and a brush sorts it out (see our cleaning tips).
• Freeze it before cleaning for kief-heavy grinders — the sticky stuff pops off easier when cold.
• Don’t over-pack it — a jammed grinder is a stiff grinder.

We carry metal grinders in a few sizes at iSmokee’s accessories section, along with papers, storage and the rest. If you’re not sure which size fits how you roll, ask.
