You already own the right roast. Medium roast is the sweet spot for AeroPress brewing, and no other roast level makes this brewer easier to use.
The AeroPress combines full immersion with gentle pressure through a paper filter. That pair pulls balanced flavor from a roast that sits between bright and dark, which is exactly what a medium roast is.
This question often hides one doubt: is medium roast good for an AeroPress, or should you buy something else? Stay put.
Medium roast keeps some fruity acidity while gaining caramel sweetness and body. It survives small brewing mistakes far better than both roast-level extremes do.
Below you will find the best settings, a full recipe, and quick fixes for a cup that goes wrong.
Medium Roast Is the AeroPress Sweet Spot
A medium roast still shows the fruity, floral flavors of the bean itself. It also gains the caramel sweetness and fuller body that longer roasting builds.
Roast level controls how acidic, sweet, bitter, and heavy your coffee can get. It also controls how easily the coffee dissolves in hot water.
That matters for the AeroPress, because this brewer steeps the grounds and then forces water through under pressure. A medium roast dissolves at a comfortable pace for both stages.
Expect balanced acidity, some caramel sweetness, round body, and a clean paper-filtered finish. The sharp edge of a light roast and the smoke of a dark roast mostly stay out of the way.
How Light, Medium, and Dark Roasts Behave in the AeroPress
Light roast keeps the most acidity, along with fruity and floral notes. It gives up its flavor slowly, so a gentle brew can leave the cup thin or sour, and it usually wants hotter water and a finer grind.
Medium roast balances fruit and caramel flavors with middle-of-the-road solubility. Small timing slips rarely ruin the cup, which makes it the easiest roast to dial in.
Dark roast brings heavy body, low acidity, and smoky or bittersweet notes. Pushed too hard, bitterness takes over fast, so most brewers give it cooler water and a shorter steep.
None of this says the other roasts are impossible in this brewer. Medium just gives you the widest margin for error and the easiest path to a repeatable cup.
The Best Brewing Settings for Medium-Roast Beans
Start with 15 grams of coffee and 225 grams of water brewed at 90°C (194°F). That is a 1:15 ratio, the baseline most AeroPress brewers land on with medium roast.
Water temperature is where medium roast gets interesting. According to James Hoffmann’s Ultimate AeroPress Technique, water straight off the boil is too aggressive for medium roasts and pulls harsh bitterness into the cup.
Hoffmann, a World Barista Champion and the author of The World Atlas of Coffee, recommends 88 to 92°C (190 to 198°F) instead. That band protects the clarity and sweetness of a medium roast, with lightly developed beans doing best near the top.
Ratio use spans about 1:14 to 1:16 depending on how strong you like your cup. The World AeroPress Championship recipe archive shows winning recipes between 1:14 and 1:15 for medium-density coffees, stirred with three to five gentle rotations.
Aim for a medium-fine grind, between fine sand and table salt in texture. Finer speeds up extraction for fast brews, while coarser suits longer steeps.
Use the table below to set every starting value for your first medium-roast AeroPress brew.
| Setting | Starting Point | How to Adjust |
| Coffee dose | 15 g | Move between 14 and 18 g for lighter or stronger cups |
| Water | 225 g | Works from about 200 to 250 g |
| Brew ratio | 1:15 | 1:14 tastes bolder; 1:16 tastes cleaner |
| Water temperature | 90°C (194°F) | Stay in the 88 to 92°C band; go cooler if bitter, warmer if sour |
| Grind size | Medium-fine, like fine sand | Finer for faster brews, coarser for longer steeps |
| Total brew time | 2:00 to 2:30 minutes | Includes about 15 seconds of stirring and a 15 to 30 second plunge |
| Filter | Rinsed paper | Swap in metal mesh to add oils and body; paper keeps the crisp, clean taste |
Standard position limits bypass, since it holds water against the coffee bed until you plunge. Inverted position offers fuller control over steep time, and both work with the same numbers.
A Step-by-Step Medium-Roast AeroPress Recipe
This recipe uses the standard position with the filter end resting over a mug. Four tools make it painless: an AeroPress coffee maker, a burr grinder, a gram scale, and a kettle with temperature control.
The AeroPress ships with paper micro-filters, a paddle, and a funnel in the box. Rinse one filter before every brew to wash away any papery taste.
Your grinder matters more than anything else here. The Baratza Encore ESP is a solid pick that handles the medium-fine range this recipe needs.
- Burrs: 40 mm conical steel
- Grind settings: 40 numbered steps
- Control: front-mounted pulse button for single dosing
- Rinse a paper filter, seat it in the cap, and twist the cap onto the chamber. Rest the brewer on a sturdy mug.
- Grind 15 g of medium-roast beans to a medium-fine consistency, about the feel of fine sand or table salt.
- Add the grounds, place the brewer on your 0.1 g scale, and tare it to zero.
- Start a timer and pour 225 g of water at 90°C from your temperature-control kettle, taking 15 to 20 seconds. Wet every ground as you pour.
- Gently stir with the paddle for about 10 seconds. Three to five slow rotations is plenty.
- Keep steeping until the timer reads 1:45. Approximately 30 seconds of contact remains for the plunge.
- At 1:45, begin pressing down slowly with steady, gentle pressure, stopping the moment you hear a soft hiss of air. Finish by roughly 2:15 to 2:30 total.
For a stronger cup, raise the dose to 17 or 18 g or move the ratio toward 1:14. For something lighter and cleaner, stretch the ratio toward 1:16 with the same 15 g dose.
Slow and gentle beats fast and forceful on the press. A rough plunge forces bitter compounds into the cup.
Troubleshooting: Fixing Sour or Bitter Cups
A bad medium-roast AeroPress cup usually comes down to one of two extraction errors. Taste first, then fix by direction.
Sour, thin, or hollow coffee can indicate under-extraction. The brew did not pull enough from the grounds.
- Raise water temperature up to 93°C (200°F).
- Grind slightly finer.
- Extend the steep by about 30 seconds.
Bitter, drying, or chalky coffee can indicate over-extraction. The brew pulled too much, including the harsh parts.
- Drop water temperature to 85 to 88°C (185 to 190°F).
- Grind slightly coarser.
- Press more gently, aiming for a 30 to 45 second plunge.
According to the Specialty Coffee Association’s coffee standards, a good extraction of brewed coffee falls between 18% and 22% of the grounds’ soluble flavor. Its guidance pairs sour cups with under-extraction and dry, astringent cups with over-extraction.
Here is the part most people miss: strength and extraction are two different dials. Dose and ratio decide how strong the cup is, while time, temperature, and grind decide what the water pulls out.
So a bitter medium roast is not a verdict on your beans, and switching roasts does not fix it. Lower the temperature or coarsen the grind first, and the same bag often tastes like new.
Once your AeroPress is dialed in, that same bag travels well. Our guide to brewing medium roast with a drip machine covers the settings that change there.
Cold brewing with a medium roast follows different rules again, since nothing about heat applies.
The Verdict on Roast for the AeroPress
Medium roast is the best all-around roast for the AeroPress, and it is the one to keep. Brew 15 g of coffee with 225 g of water at 88 to 92°C using a 1:15 ratio, press gently, and stop at the hiss.
Run one test brew with the starting numbers above, then adjust one setting at a time until the cup tastes right.
