For drip coffee, medium grind is the right starting point, with a texture similar to granulated sea salt or coarse sand. If your coffee tastes sour, grind finer. If it tastes bitter, grind coarser.
That three-part rule covers most situations, but the specific drip machine you use changes where “medium” actually lands. A flat-bottom basket brewer behaves differently from a cone-shaped basket, and a commercial batch brewer is different again.
This guide covers the baseline setting, how to read your machine’s basket type, and how to dial in by taste and brew time, so you stop guessing and start brewing a balanced cup.
The Medium Grind Baseline for Drip Coffee
Medium grind is the starting point for standard automatic drip coffee makers, according to the Blue Bottle Coffee brewing guide. Visually, it looks like granulated sea salt or coarse sand.
The National Coffee Association describes the right texture for drip brewing the same way: roughly the consistency of sea salt, neither powdery nor chunky. That tactile reference matters because grinder dial numbers are not standardized across brands.
A setting labeled “5” on one grinder may produce a completely different particle size than “5” on another. Use the sea salt texture as your reference, not the number on the dial.
Grind size works by controlling two things at once: surface area and flow resistance. A finer grind exposes more coffee surface to water and slows the water’s path through the grounds.
A coarser grind lets water move through faster but contacts less surface area per particle. Medium grind balances both so water spends the right amount of time in contact with the coffee.
For a standard 8 to 10 cup automatic drip brewer, Blue Bottle Coffee notes the full brew cycle should complete in roughly 4.5 to 6 minutes. A cycle finishing much faster than that with weak-tasting coffee points to a grind that is too coarse.
Grind Settings by Drip Machine Type
The basket shape inside your drip machine changes how water flows through the coffee bed. That means the ideal medium grind can shift slightly depending on your brewer.
Use the table below to find the right starting grind for your specific drip setup.
| Drip Brewer Type | Basket Style | Starting Grind | Texture Reference |
|---|---|---|---|
| Standard home drip (e.g., Mr. Coffee, Cuisinart) | Flat-bottom basket | Medium | Granulated sea salt |
| Specialty certified drip (e.g., Technivorm Moccamaster) | Cone or flat, variable | Medium to medium-coarse | Rough sand or kosher salt |
| Commercial batch brewer (e.g., Fetco, Bunn) | Large flat-bed | Medium-coarse | Rough coastal sand |
As James Hoffmann explains in The World Atlas of Coffee, flat-bottom baskets spread the coffee bed thinner and require a true medium grind. Deeper conical baskets, when used for full batch brewing, can benefit from a slightly coarser setting to prevent the water flow from slowing too much.
For most home brewers with a standard flat-bottom basket, medium is correct and needs no adjustment before your first brew.
Grinder Settings by Model
Because grinder scales vary by manufacturer, the texture reference above is more reliable than any dial number. That said, Baratza’s grinder settings guidance gives concrete starting points for popular home burr grinders.
Use the table below to find a starting point for your specific grinder, then adjust from there based on taste.
| Grinder | Starting Setting for Drip |
|---|---|
| Baratza Encore or Virtuoso+ | Settings 14 to 18 (out of 40) |
| Fellow Ode Gen 2 | Settings 4 to 6 |
| Breville Smart Grinder Pro | Settings 30 to 42 |
| Comandante C40 Mk4 | 20 to 25 clicks |
| Timemore Chestnut C2 or C3 | 15 to 19 clicks |
| Wilfa Svart | Center of the “Filter” marker band |
Baratza’s grinder settings guidance recommends starting at setting 18 on the Encore and Virtuoso+ for automatic drip brewers using standard paper basket filters. For cone-shaped paper filters, Baratza suggests adjusting down toward settings 14 to 16.
These settings are starting points, not final answers. Your specific water, coffee freshness, and roast level will all influence the right position.
How to Adjust by Taste and Brew Time
Taste is the most reliable diagnostic tool for grind adjustment. A cup that is sour, thin, or hollow can indicate under-extraction, where water moved through the grounds too quickly.
Adjust your grinder one small step finer and brew again. Finer grind increases the coffee bed’s resistance, slowing the water and allowing more even extraction.
A cup that is bitter, dry, or astringent can indicate over-extraction, where water stayed in contact with the grounds too long. Move one step coarser to reduce resistance and shorten contact time.
Changing dose (the amount of coffee) when the real problem is grind size often makes the imbalance worse rather than better. A sour cup brewed at a finer grind will taste different from a sour cup fixed by adding more coffee, because the root cause is contact time, not coffee quantity.
Brew time is a secondary check. For a standard 8 to 10 cup automatic drip machine, the full cycle should fall between roughly 4.5 and 6 minutes, according to Blue Bottle Coffee’s brewing guidance.
If water pools and overflows the filter basket, the grind is too fine or the bed is clogged with fine particles. If the cycle finishes in under 3.5 minutes and the cup tastes weak, the grind is too coarse.
The Specialty Coffee Association defines the ideal extraction yield as 18 to 22 percent of the coffee’s soluble mass. Grind size is your primary control variable for reaching that range on a standard drip machine, where you cannot adjust water temperature or flow rate.
For more on adjusting grind for other brewing methods, see how grind differs for French press brewing or the guide on setting your grinder for espresso.
What to Do If the Grind Setting Still Feels Off
If adjusting grind alone does not resolve the taste problem, check whether your grinder is producing consistent particle sizes. Blade grinders chop coffee unevenly, producing a mix of fine dust and large chunks that causes inconsistent extraction regardless of the setting used.
Switching to a burr grinder for drip coffee produces a more uniform grind and gives you real control over extraction. Both flat burr and conical burr designs work well for drip.
Also check coffee freshness. Stale beans, typically more than four to six weeks past roast date, extract differently than fresh ones. Grind size adjustments have less effect when the coffee itself is depleted of soluble compounds.
If you are experimenting with other manual brewing methods alongside drip, the grind principles are related but not identical. AeroPress grind settings differ because you control contact time directly through your technique rather than relying on a machine’s fixed water delivery rate.
Grind Setting Summary for Drip Coffee
For standard automatic drip coffee, start with medium grind, described by the National Coffee Association and Blue Bottle Coffee as the texture of granulated sea salt. On a Baratza Encore, that means starting around setting 14 to 18, adjusting finer if the coffee tastes sour and coarser if it tastes bitter.
Your next step is to brew a cup, taste it, and move one small step in the right direction. A single adjustment, confirmed by taste, is almost always enough to find the setting your specific beans and machine need.
