Using Water Temperature To Manage Acidity In Coffee

Using Water Temperature To Manage Acidity In Coffee

 Controlling Coffee Acidity

To brew delicious coffee, variables must be balanced. Water temperature is one variable that is rarely considered - yet is extremely important. As a bonus, it can be controlled, set, and never needs to be worried about again.


You can accomplish a few things by knowing how water temperature affects your coffee. You can make adjustments to your final cup through temperature adjustments if you'd like. This way, you always have the knowledge you need to use a consistent and reliable water source.


Coffee Extraction and Water 

Your coffee grounds are extracted more quickly from boiling water, as you are probably aware already. A balanced extraction can be achieved in 2-4 minutes when water is near-boiling—the time required for cold brew coffee to be made at the water temperature.

Hot brewing is best done between 195 and 205 degrees Fahrenheit.

 The temperature here is just right for careful and rapid extraction, without being too hot.

 Controlling Coffee Acidity

  • It is widespread for over 205 degrees Fahrenheit to produce bitter coffee as the beans are over-extracted.
  • The sour flavor of coffee can often be associated with water below 195 degrees, making it difficult to extract.


A water temperature between 195 and 205 degrees is not the objective gold standard for brewing coffee. Because it tends to make the best, most balanced coffee around the world, most people in the world use this range; even if you choose to depart from this established temperature range, I wouldn't recommend it unless you have extensive experience in brewing espresso.


The results achieved by coffee professionals can also vary greatly depending on the temperature used. In 2013, a finalist of the World Aeropress Championship used 176-degree water. Aeropress recipes by another significant figure in the world of coffee frequently use 190 degrees.


The classic range of 195 to 205 degrees can be done if you control other coffee variables to a master's level, but for most, 195 to 205 degrees is good enough.



We all know that what we perceive when drinking coffee is heavily influenced by extraction. In this case, the brewing water temperature can also significantly impact the extraction rate of the coffee.


According to the water temperature, every molecule has an optimal amount of extraction. Coffee compounds can be extracted primarily from hot water, and the hotter the water is, the easier it is to remove these compounds.


Heat increases the molecules of water as the temperature rises. When they both move faster, coffee molecules and water molecules become more intertwined.


As these two molecules interact, extraction takes place more readily. This results in the water molecule removing more compounds from the coffee molecules, such that we taste and smell the coffee in the drink.


A low-temperature water temperature won't extract volatile compounds essential for fully comprehending coffee's flavor.


Researchers indicate this change occurs when beverages like cold brew are extracted at low temperatures (varying from 22°C to 5°C for hours at a time).


Since most compounds are extracted fairly evenly, a complex sensory profile results, sugar, organic acids, chlorogenic acids, caffeine, and other less soluble compounds that take longer to remove are all subject to maximum extraction rates.


As a result of this long, low-temperature extraction, the sugars in the beverage have the opportunity to extract, providing a sweet, caramel-like taste. It also tends to have lower levels of bitterness and astringency in cold-brewed coffee.


What's the deal with acidity in coffee?

 Controlling Coffee Acidity

People mostly dislike it, based on our experience, first of all. The taste of olives can be unpleasant for some, however, when they first taste them. But I know many who have now become addicted to their salty, bitter, and acidic flavor.


We now know that this is a taste that is acquired. Whether you love or hate coffee, even in its most basic commodity form, is a matter of opinion. There are some people, however, who master the taste. There are also specialty coffees, single-origin, roasted carefully, meaning that the flavors are preserved and enhanced. The experience can be shocking for a consumer of commodity coffee. It either makes you happy, or it makes you sad. Despite this, you can learn to appreciate the flavor and never look back (if you're reading this, you probably know what I mean).


It is a fact that acidity is suitable for specialty coffee. It is possible to get hold of a bag of beans with excessive acidity and want to tone it down.


Using Water Temperature To Manage Acidity


Additionally, the water temperature can affect extraction rates. Compounds extract more quickly when the water is hotter. Extraction is slower at cooler temperatures. The way cold brew tastes is sweet and smooth, with only a small amount of acidity (this is why some compounds will not extract under certain temperatures). Additionally, the grind size and brew time will affect your brew.


According to Joe, brew time and temperature should be higher. "I like to brew my beers at 204oF/95oC to 205oF/96oC because it highlights the acidity." he says.


According to Steve, this approach will work if the quality of the water is good. Some people avoid bitterness by using lower temperatures. When the water is good (and everything else is controlled), the acidity is more pronounced at 94oC/202oF than 91oC/197oF.


We get to taste our coffee precisely the way we like it when we brew it ourselves. Even though it can be challenging at times, mastering these concepts will enable us to brew coffee that tastes good every time.


Don't be afraid to alter your coffee recipe. Change up the type of water you drink. Experiment with different water temperatures. Simply changing the temperature by one degree may transform an ordinary brew into vibrant, fruity, and fruity-tasting.


Is There A Perfect Coffee Brewing Temperature?

 Controlling Coffee Acidity

The National Coffee Association recommends water temperatures between 195°F and 205°F for extraction, just below boiling point - 212°F. Its advantage is that it can be used for all types of brewing methods. No matter what way you choose, pour-over, French press, or anything else, stay within the temperature range, and you'll be fine. 


The temperature may need to be raised or lowered depending on the type of roast you're brewing. Brew at a higher temperature to speed up the extraction process and obtain a lighter roast when you make your coffee. Avoid over-extraction by brewing at a lower temperature to minimize bitter flavors.

What Equipment Do I Need to Control the Temperature?


You can't have a good coffee arsenal without a thermometer. Infrared laser thermometers allow you to measure temperatures from a distance accurately, so they are a good choice if you want something more high-end. When you use a coffee thermometer, measure the weight of coffee and water in the filtered slurry - the mass in the filter when brewing.

Controlling Coffee Acidity 

You can achieve an ideal water temperature with an electric gooseneck kettle. Ideally, it would be best if you looked for a kettle that has an adjustable temperature feature so that you can set the temperature each time.


Perhaps you should consider an upgrade to your old drip coffee maker. How come? It's important to note that most drip coffee makers lack the Specialty Coffee Association of America (SCAA).


All of this may seem rather extreme for a cup of coffee in the morning. It is essential to be precise and precise about water brewing temperature if you want to get the best out of your coffee.


Should You Manipulate Water Temperature To Improve Your Coffee's Flavor?


If you don't have a special kettle that heats water to specific temperatures, it can be challenging to achieve particular flavors with water temperature. Although these are extremely handy, they are not razor precise and usually cost at least $85 each.


Making small changes to your grind size instead of adjusting your water temperature is a much better method of improving your coffee. Water temperature can be controlled more easily and quickly by changing the grind size.


JavaPresse designed its burr grinder so users can refine their coffee's flavor without having to fiddle a lot with their water temperature and other variables.


Check it out for yourself if you want to improve your coffee's quality and enjoy the rich satisfaction of properly brewed coffee.


You don't need to worry about the water temperature for coffee as long as you can standardize it. When variables are turned into reliable constants, it becomes much easier to make balanced coffee.


There's no question that the ideal temperature range for coffee water ranges from 195 to 205 degrees Fahrenheit. It would be best if you could keep that nugget of information in your head at the very least.

Harnessing Water Temperature to Control Acidity in Your Coffee

The art of brewing coffee is a delicate dance of flavors and aromas, with water temperature playing a pivotal role in shaping the final outcome. For those seeking a smoother, less acidic cup of coffee, understanding how water temperature influences acidity is a key step. By adjusting the water temperature during brewing, you can master the art of managing acidity and crafting a coffee experience that suits your taste preferences. Let's delve into the science behind it and explore how you can harness water temperature to your advantage.

The Science of Acidity in Coffee

Acidity in coffee refers to the bright, tangy notes that can range from citrusy to fruity. While acidity contributes complexity and liveliness to the cup, excessive acidity can be off-putting to some palates or even cause discomfort for those with sensitive stomachs. Water temperature comes into play due to its role in extracting different compounds from the coffee grounds.

Hotter Water and Acidity

Brewing coffee with hotter water, typically in the range of 195-205°F (90-96°C), tends to result in increased acidity. Hot water facilitates the extraction of acidic compounds, lending the cup a vibrant and tangy character. This temperature range is often used for methods like pour-over, drip brewing, and espresso.

Cooler Water and Reduced Acidity

Lowering the water temperature, around 175-185°F (80-85°C), during brewing can lead to a reduction in acidity. Cooler water extracts fewer acidic compounds, resulting in a smoother and milder taste profile. This temperature range is commonly employed in methods like cold brewing or immersion methods such as French press.

Crafting Your Low Acid Brew

To control acidity using water temperature, follow these steps:

  1. Choose Your Method: Determine which brewing method you'll use. For a less acidic cup, consider methods like cold brewing or French press.

  2. Heat Your Water: Depending on the method, heat your water to the appropriate temperature. For lower acidity, aim for the cooler temperature range mentioned earlier.

  3. Pre-Wet the Coffee Grounds: If using a pour-over or drip method, start by pre-wetting the coffee grounds with a small amount of water to allow them to bloom.

  4. Brew with Care: During brewing, maintain the chosen water temperature. Follow the recommended brewing times for your selected method.

  5. Experiment and Adjust: Taste your coffee and take note of the acidity level. If you desire even lower acidity, you can experiment with slightly cooler water or longer brewing times.

Final Thoughts

Remember that the interplay of water temperature and coffee grounds is a nuanced process. While controlling water temperature can indeed influence acidity, it's just one of several variables that contribute to the overall flavor profile. By understanding how water temperature affects acidity and experimenting with different temperatures and brewing methods, you can uncover a world of flavor possibilities. Whether you prefer a vibrant and tangy cup or a mellow and smooth brew, the control is in your hands – or rather, in the temperature of your water.
