Does Hotter Water Make Stronger Coffee?

You can’t brew a delicious cup of coffee without water because that’s where all the flavor comes from! Water works by drawing the flavor from your coffee ground referred to as extraction. If you have recently started brewing your coffee at home, you may have questions about water temperature. Does hotter water make stronger coffee?

Coffee grounds have limited caffeine and flavor that can be extracted from each ground bean. If you use boiling water, you will over-extract your coffee, resulting in a flavorless and bitter cup of coffee. The ideal water temperature for brewing coffee is between 195 and 205 degrees Fahrenheit.

When brewing your coffee at home, you must understand how water temperature affects the brewing process. Continue reading with us as we explain the essentials of brewing your coffee for the richest, strongest, and most delicious taste!

How Will Water Temperature Affect Your Coffee?

It is crucial to use the correct water temperature when you’re brewing your coffee.

If your water is too cold, you risk under-extracting your beans, resulting in a weak cup of coffee that could taste sour or salty. If you use boiling water, you will not get a stronger cup of coffee. Instead, you risk over-extraction, resulting in a bitter and flavorless sour cup of coffee.

Water temperature is essential to the brewing process, as your coffee’s flavor completely depends on the water. Coffee beans get their flavor from the hot water dissolving the soluble compounds inside the ground beans.

What Is The Ideal Water Temperature For Brewing Coffee?

Now that you know that hotter water doesn’t necessarily mean stronger coffee, you need to look into the ideal water temperature to discover the sweet spot.

Some coffee fanatics claim that some roasts taste better at certain temperatures, which is true. While experts claim that the perfect temperature range for brewing coffee is anywhere between 195 and 205 degrees Fahrenheit, lighter and darker roasts may benefit from different temperatures.

If you have a lighter roast and prefer your cup of coffee to be on the stronger side, it is recommended to brew your grounds at a slightly higher temperature, as it will speed up the extraction process.

You can get enough strength and flavor for a darker roast without over-extracting at 190 degrees Fahrenheit. A dark roast can easily be over-extracted, and you risk your coffee tasting bitter.

If you have both light and dark roast at home, you can lower or raise your brewing temperature and experiment to find your desired strength.

However, keep in mind that you should never use water with a temperature of 212 degrees Fahrenheit (Boiling point) as you will completely burn your coffee grounds, and they will become burnt, leaving you with a foul-tasting cup of coffee.

Remember that it may take a few practice runs to successfully obtain the perfect cup of coffee at your desired strength.

If you use a manual brewer, such as a pour-over or a plunger, you may have some difficulty initially, but as you grow accustomed to your brewer, you’ll get the hang of it in no time!

How To Control The Water Temperature During Brewing

If you have difficulty controlling the temperature while brewing your coffee, don’t stress! It will be a useful tool if you don’t already have a thermometer in your coffee arsenal or kitchen!

A traditional thermometer would be more than enough, but if you want something more high-end, you can invest in an infrared laser thermometer. This type of thermometer will allow you to measure your water temperature from a distance.

No matter what thermometer you choose, always remember to measure the temperature of the slurry during the brewing process.

However, if you want to go all the way to achieve the perfect cup of joe, why not purchase an electric gooseneck kettle? These kettles are useful gadgets that will help you set and achieve the perfect water temperature for your coffee.

You can set them to the correct temperature manually, and when the desired temperature is reached, the kettle will turn itself off or keep the temperature levels stable.

Water Tips For When You’re Brewing Coffee

The transparent tap water most of us would use for the base of our coffee has a lot inside. Despite it being transparent, it has several solids and solubles. Tap water contains many unwanted minerals, such as chlorine, magnesium, fluoride, and calcium.

All of these minerals get added to tap water as it passes from the water source into your coffee and body. Because tap water isn’t completely pure, this will significantly impact how your cup of coffee tastes.

Keep in mind that even if you drink tap water, it won’t necessarily be bad for your health or impact you, but these unpleasant substances could make your coffee taste bad or flat, even if you brewed it at the correct temperature.

Make sure the water you use for your coffee is clean and fresh by look, taste, and smell. It would be best to use spring water and always start with cold water if you’re going to use it for brewing your coffee.

Hot water from a tap is also unsuitable, as it is often not fresh and could have foul odors or tastes. The type of water you use won’t only impact your coffee’s overall taste but also how long your brewing equipment will remain functional.

Suppose you don’t use pure water that contains extra minerals, especially tap water. In that case, it could build up residue inside your brewers, kettles, or even on the inside of your countertops if you’re using a countertop espresso machine.

If you don’t take care to use the highest quality of water possible, the residue could become next to impossible to clean over time, compromising the longevity of your brewing equipment, which is why the quality of your water is the second most important factor after the temperature!


Learning how to achieve the ideal water temperature when brewing your coffee could make all the difference in your cup. You can get the strongest coffee by sticking to the correct temperatures, as too hot or too cold water could result in over or under-extraction.
