Dial in your Hario Mini Slim Plus for pour-over and cold brew with a simple click-based grind size chart and step-by-step adjustment process. Learn how to set, test, and fine-tune your grind.

Quick answer

For pour-over, start with 8–10 clicks from closed on the Hario Mini Slim Plus; for cold brew, use 14–16 clicks. Adjust in one-click increments based on taste and brew time.

Why grind size matters for these brew methods

Pour-over relies on a moderate flow rate; too fine a grind stalls the drip and over-extracts, while too coarse a grind speeds through and under-extracts. Cold brew uses a long steep, so a coarser grind prevents bitterness and makes filtering easier.

The Hario Mini Slim Plus uses a click-based adjustment nut under the hopper. Each click is a discrete step, so you can count and return to a setting. The grinder does not include a printed grind chart, so you’ll rely on click counts and visual cues.

When to ignore click counts and trust your senses

Click counts are a starting point, not a rule. Bean density, roast level, and age affect how a given setting performs. If your pour-over drains faster than expected or tastes sour, go finer; if it tastes bitter or stalls, go coarser. For cold brew, if the concentrate feels weak, grind finer; if it’s muddy or harsh, grind coarser.

Always adjust in single-click increments and change only one variable at a time. Keep notes of click count, dose, water, and time to build your own reference chart.

Step-by-step grind adjustment

Start from a clean grinder: Empty any old beans and set the adjustment nut to the fully closed position (turn clockwise until it stops). Do not overtighten; just close it gently. A clean grinder prevents stale flavors from affecting your test.
Set for pour-over: Turn the nut counterclockwise 8 clicks for a starting point. Grind a small sample and check the texture: it should resemble fine sea salt, with some grit but no powder. If the grind looks like flour, go coarser by 2 clicks; if it looks like coarse sand, go finer by 1 click.
Brew and taste: Brew a pour-over with your usual recipe. If the drawdown is slower than 3–4 minutes or the cup tastes bitter, go 1–2 clicks coarser. If it’s faster than 2 minutes or tastes weak/sour, go 1–2 clicks finer. Adjust in single-click increments and re-test before changing again.
Set for cold brew: Turn the nut counterclockwise 14 clicks from closed. Grind a sample; it should look like coarse cornmeal, with distinct particles and minimal fines. If you see many fine particles, go 2 clicks coarser to avoid a muddy brew.
Brew and evaluate cold brew: Steep 1 part coffee to 4 parts water by weight for 12–16 hours. If the concentrate tastes weak or thin, grind 1–2 clicks finer. If it’s harsh or bitter, grind 1–2 clicks coarser. Filter through a fine-mesh sieve or paper filter to remove fines before serving.
Record your settings: Note the click count, coffee dose, water amount, and brew time for each method. Keep a small log in your brewing notebook or phone. A written log makes it easy to return to a favorite setting after cleaning or travel.
