The Right Coffee Brewing Temperature – How Hot Should Coffee Be?

'Piping hot coffee' screams the flashing neon sign in the overlarge corner cafe windows. We’ve all seen signs like this, but, if you are like me, you have wondered whether “piping hot” is really the best temperature for coffee.

Contrary to popular belief, coffee hot enough to singe your taste buds is not suitable for drinking (real shocker, I know).

So, how hot should coffee be?

Today I am going to tell you what (if not “piping hot”) is the proper temperature at which to serve coffee.

Brewing Temp vs. Serving Temp

So let’s just get this out of the way: the brewing temperature for coffee is different than the serving temperature for coffee!

This may seem like a no-brainer, considering that the standard brewing temperature for coffee (195–205°F) is hot enough to settle a half million dollar lawsuit with McDonald's; however, there aren’t many drinks prepared with with such considerations.

Unless you are making some refreshing cold brew or competing for the World AeroPress Championship (those guys use some ridiculously low brew temps), your serving temperature is going to be well below your brew temperature.

How Low Do You Go?

Before you begin to think that I am steering you towards a lukewarm cup of joe, fear not, because not even I would stoop that low (I promise that was my only pun).

Though I’m sure you’d love to hear me quote some science, there is little conclusive evidence on how taste is affected by temperature; however, there are some who’ve researched the matter.

A few studies have shown that higher serving temperatures — for both foods and beverages — amplify perceptions of sweetness and bitterness, but sourness and saltiness become more pronounced at lower temperatures.

Other studies, however, have found that higher temperatures can stifle taste, and mask the delicate nuances of a drink.

Unfortunately, none of these studies speak directly about coffee, but perhaps we can draw an important conclusion from their results:

To punctuate the sweet and bitter notes of coffee (and mask its sourness) a higher serving temperature is necessary, but go too high and you will deaden your ability to truly taste your delicious brew.

... Not Too Low

Though the scientists weren’t much help in narrowing down an appropriate serving temperature for your coffee, we can always look to that quirky and overly compulsive community of coffee experts who tirelessly experiment and obsess over their brews.

According to the National Coffee Association of the USA — which many large companies in the food and beverage industry listen to — coffee should be served at around 180–185°F, not much lower than the standard brew temperature. However, the fellas over at Coffee Detective seem to think that this is too high of a temperature.

They suggest serving coffee at somewhere within the range of 155–175°F, and recommend leaning more towards the lower end of the scale with higher quality coffee beans. This assumption — lower temperatures are better for higher quality coffees — fits well with what we already know: use temperature to either reveal or mask a coffee’s flavors.

... Just Low Enough

Although 155°F might seem like a low temperature for coffee, there are some who suggest even that is too high.

For some, 120–140°F is the ideal range for drinking coffee. These opponents to “piping hot” coffee argue that it is difficult to taste the subtle flavors of coffee at temperatures above 150°F. They believe that only at 120–140°F the (otherwise overshadowed) notes of sweetness, as well as acidity, shine through.

Surprisingly, this recommendation also matches the sciency garble that I went over earlier: lower temperatures allow for notes of sourness/bitterness to become more pronounced, but higher temperatures can mask a drink’s more delicate flavors, like sweetness.

For God's Sake!  What's the Right Coffee Tempreature Then?

Perhaps the only concrete fact we can glean from all this is that as long as your coffee is not lukewarm or scalding hot, the right serving temperature for you is up to your own unique flavor preferences.

Despite this lack of a definitive answer, there are some good directional signs to help you find that perfect temperature:

  • For those of you who prefer the rounded, sweet, and bitter notes of coffee, you will be better off sticking within the 155–175°F range.
  • But if you more enjoy a brighter, sharper, and more acidic cup, aim within the 120–140°F range.
  • Lastly, if you care more about the warming sensation of hot coffee than you do the flavor, a cup within the range of 180-185°F would be best for you.

Whichever way you lean, make sure that your coffee stays hot, because reheating can ruin its flavor.

Though the question “how hot should coffee be?” may be a tricky one to answer, there are some simple rules to help guide you to your own right answer.

As with most things drink related, the correct coffee temperature, assuming you haven’t strayed below 120°F or above 185°F, is mostly a matter of personal flavor preferences.

I enjoyed your article. One thing that I have noticed is that whether or not you you keep it warm on a burner or in a carafe seems to make no difference as long as it is consumed with 20 – 30 minutes. Longer then that, even in a thermal pot the coffee continues to “cook”. I have a Bonavita auto drip with a thermal pot and it was one of the few drip makers that brews at the correct temperature. I actually love French press the most but for health reasons I have opted to give that up as my daily method and save it for special times. Supposedly filters are better for your cholesterol and thank God for the Bonavita because it was far cheaper than a Technivorm! I have found that experimenting with grind size dramatically alters the flavor as well.

I’m still not sure about brewing and drinking temperatures, as I am not inclined to do the work of converting Fahrenheit to Celcius. Pity – it meant I didn’t fully enjoy the article. Perhaps give the Celcius numbers (most used in the world) in brackets?

    120-140°F = 49-60°C ≈ 50-60°C
    155-175°F = 68-79°C ≈ 70-80°C
    180-185°F = 82-85°C ≈ 80-85°C

I too use and prefer Celsius, but doesn’t the calculator on your computer have a unit conversion feature that it makes it very easy (even easier than commenting) to determine C given F ??
