Brew French press coffee with water at 194 to 205 °F (90 to 96 °C). The National Coffee Association gives about 93 ± 3 °C for a French press: boil the water, take it off the heat, wait about 30 seconds and confirm with a thermometer. Preheat the press, because the brew cools during the roughly four-minute steep.
That 194 to 205 °F is the same range as the familiar “195–205 °F” figure. The NCA, writing specifically about the French press, says “the ideal water temperature for a French press is around 93 ± 3°C”, which is 90–96 °C. The Specialty Coffee Association uses the same range in its home brewer standard, which requires the slurry to “reach a temperature in the 90 to 96°C range”, but that standard tests electric drip brewers and its scope excludes French presses.

195–205 °F and 90–96 °C are not quite the same numbers
Both standards are written in Celsius. Converted straight across, 90 °C is 194 °F and 96 °C is 204.8 °F. So the very common “195 to 205 °F” is a rounded Fahrenheit rendering of the same range — about one degree Fahrenheit high at the bottom and a fraction high at the top. That is smaller than the error of most kitchen thermometers and it changes nothing you would taste. We are spelling it out because this page is the one other pages cite, and a cited page should not quietly round a source.
If you want one number rather than a range, 93 °C / 199 °F is the midpoint both documents are built around.
Where does 194 to 205 °F come from?
- National Coffee Association, French press coffee. “If you’re using a kettle that does not have a built-in thermometer, plan to have one on hand—the ideal water temperature for a French press is around 93 ± 3°C.” Its summary box repeats it: “Brewing temperature: 93 ± 3°C” (aboutcoffee.org, French press coffee). This is the best-hosted citation and the one to use if you only want one.
- The NCA attributes that figure to a standard, on its pour-over page. “The SCA Standard 102-2024 Coffee Value Assessment: Sample Preparation and Tasting Mechanics suggests that the optimal water temperature before pouring over coffee grounds is 93 ± 3°C” (aboutcoffee.org, Pour-over coffee). Note where that attribution sits: it is on the pour-over page. The French press page gives the same 93 ± 3 °C without naming the standard.
- SCA Standard 310-2021, Home Coffee Brewers, §6.2. “The slurry temperature (using a floating array of three thermocouples) shall reach a temperature in the 90 to 96°C range by the moment when 33% of the water mass has been sprayed onto the coffee. The temperature shall be maintained within the 90 to 96°C range for the remainder of the brew cycle.” Its specification table lists §6.2 Brewing temperature as “90 to 96°C” (SCA Standard 310-2021, PDF). Its scope covers electric filter brewers; French press style devices are excluded. Caveat on that link: the SCA now offers this standard only to members, behind a login, so the copy we cite is an SCA-branded PDF hosted by coffeegeek.com. It carries the SCA’s own reproduction notice — “Permission is granted to reproduce this standard partially or completely, with the consent of and attribution to the SCA” — and its named contributor list. If the SCA reposts it, this citation should be re-pointed.
How to hit it without fussing
The NCA’s step one is the whole trick if you do not own a thermometer: “Bring your water to a boil, remove from heat and allow to rest for about 30 seconds. Use your thermometer to confirm the water is around 93 ± 3°C (or your preferred temperature).” Water at a rolling boil is 100 °C at sea level, which is above the range; a short rest off the heat brings it down into it. How long the rest needs to be depends on your kettle, your room and how much water is in it, so 30 seconds is a starting point rather than a rule. Nobody at this site has timed a cooling curve for you, and a page that prints one without saying whose kettle it came from is guessing.
Altitude matters here too: the higher you are, the lower water boils, so at elevation freshly boiled water may already be inside the range with little or no rest. A thermometer settles it, and we are not going to print an altitude table nobody here has measured against. A thermometer is the only piece of kit that turns any of this from opinion into measurement — see coffee tools and accessories.
A French press loses heat, and that is the real temperature problem
Getting the water right at the moment you pour is the easy half. A French press then holds that water for about four minutes in a vessel that is often a single wall of glass sitting in room-temperature air, so the brew is cooling the whole time it is extracting. The NCA makes the same point when it discusses buying one: double-walled presses “maintain a more consistent temperature throughout the brewing, which makes for higher-quality coffee, and, after brewing, keep the coffee hot for longer.”
Two things follow, and neither needs a number:
- Preheat the press. Fill it with hot water, swirl, tip it out, then brew. A cold glass cylinder takes heat out of your brew, and preheating is free.
- Do not chase the loss with hotter water. Starting above 96 °C to “allow for cooling” puts the grounds in contact with water outside the range at exactly the moment extraction is fastest. Preheat instead, or use a double-walled press.
The rest of the French press method, from the same source
Temperature is one of four variables and it is not the one that usually spoils a cup. The NCA’s French press summary gives the other three, and its step-by-step gives the technique:
| Variable | What the NCA specifies for a French press |
|---|---|
| Water temperature | 93 ± 3 °C (90–96 °C, 194–205 °F) |
| Coffee-to-water ratio | “1 gram of coffee to 10–16 grams of water (1:10 to 1:16)” |
| Grind | “Coarse (like rock salt)” |
| Contact time | “4 minutes, approximately, of contact between coffee and water” |
That 1:10 to 1:16 is not a contradiction of this site’s house ratio. Our house figure for drip and filter brewing is the SCA’s standard brew ratio — “The standard brew ratio of 55 g of coffee per 1.000 kg of 17±3°C water” (SCA Standard 310-2021, §7.1.5), which is 1:18 by weight. A French press is a full-immersion brewer with a metal filter and it is legitimately dosed heavier. Use 1:10 to 1:16 here. Stronger means more coffee, not less, and a coffee “cup” is 6 fl oz, not 8. More on dosing at how many beans per cup of coffee, and for a full drip pot, how much ground coffee for 12 cups works the house ratio out in grams and tablespoons.
The plunge and the pour matter as much as the thermometer. The NCA’s steps: add grounds, then hot water; “Wait about one minute, until you see coffee grounds forming a ‘crust’ at the top of the carafe. That’s normal! Just use a wooden spoon to stir gently, breaking up the crust”; put the lid on with the plunger up and steep about three more minutes; then “Gently push the plunger all the way down and serve immediately, or transfer to another container. (If left in a French press, coffee will continue to brew and turn bitter.)”
Decant. That parenthesis is the single most useful sentence on the NCA’s page and the one most French press guides leave out. The grounds stay in the water after you plunge, so the second cup out of the same press is a longer brew than the first. If you are not drinking it straight away, pour it into a warmed jug or thermos.
Does roast level or grind size change the water temperature?
Not in the sources this page uses. Neither the NCA nor the SCA brewer standard prescribes a different brew temperature by roast level; each gives one range. Roasting does drive out moisture and open up the bean’s structure, so a dark roast is less dense than a light one (the mass-loss and porosity measurements are on our coffee roast levels page), but neither source turns that into a temperature rule. The NCA’s roast advice for the French press is about taste: “Coffees with a medium to dark roast tend to work well in a French press, but you can experiment with different roasts to find what you like best.” If a light roast tastes thin, the lever with published backing is grind and, within the NCA’s 1:10 to 1:16 ratio, dose, not water hotter than 96 °C.
Grind size is a separate dial from temperature. The NCA’s own troubleshooting adjusts the grind, not the heat: “Your coffee tastes bitter or sour: it may be ground too fine (over-extracted), so try a larger, coarser grind” and “Your coffee tastes flat or watery: it may be ground too coarse (under-extracted), so try a smaller, finer grind.”
What we have not measured
Every figure on this page is quoted from a published document. Nobody here has brewed a side-by-side at 90 °C and 96 °C, timed a kettle’s cooling curve, or measured how fast a particular press loses heat, and no tasting note on this page is ours. If you want to settle it in your own kitchen, the experiment is a scale, a thermometer and the same coffee twice: brew one press at 91 °C and one at 95 °C, everything else held fixed, and taste them side by side.
One last thing worth knowing about this brewer specifically, since it is a health point rather than a taste one: a French press uses a metal filter, and metal filters let through cafestol and kahweol, the coffee oils that raise LDL cholesterol. The measurements and what they do and do not show are on our coffee filter types page. It is a filter question, not a temperature question, but if you drink several presses a day it is the more consequential of the two.

Corrections to earlier versions of this page
- An earlier version said “Two authorities land on the same range” and cited the Specialty Coffee Association’s home brewer standard beside the National Coffee Association’s French press figure. That standard tests electric drip brewers and its scope excludes French presses, so the NCA is the only source here written for the French press.
- An earlier version said a cold glass cylinder takes heat out of the brew “in the first thirty seconds”. No source gave that timing, so it was removed.
- An earlier version said “The Specialty Coffee Association recommends a temperature range of 195 to 205 degrees Fahrenheit (90 to 96 degrees Celsius) for optimal extraction.” and linked to nothing. The numbers were right; the sources are now listed above.
- An earlier version said “Lighter roasts typically require higher temperatures for optimal extraction, as they are denser than darker roasts.” The density half is right; neither source sets a temperature by roast.
- An earlier version said a finer grind needs a lower brewing temperature and a coarser grind a slightly higher one. That was unsourced; the NCA adjusts the grind, not the heat.
- An earlier version had a link labeled “[Amazon.com]” that went to a Serious Eats article and carried a sponsored link attribute. It was removed, along with an FAQ block whose answers are in the text.
