What Is the Boiling Point of Coffee?

So what is it that makes your coffee so irresistible? Is it the earthy aroma, the rich flavors, or simply the caffeine boost? Well, we can’t give you any definitive answers just yet. But we can help you stir things up a bit by introducing you to the concept of the boiling point of coffee.

If you’ve ever taken high school chemistry, you might remember how different solutions respond differently to heat depending on their pH levels. In simplest terms, “pH” stands for “potential of Hydrogen” and indicates how acidic or alkaline a solution is by measuring its hydrogen ions.

Neutral water has a pH level of 7. Continue reading for the complete rundown on the temperature of boiling coffee.

What is the Boiling Point of Coffee?

The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit. This means that if you were to heat water in a pot over a fire, it would take a lot of time for it to actually boil.

The boiling point of any given solution is the temperature at which it changes from a liquid to a gas. In other words, the boiling point of something is the point at which it finally reaches its boiling point and vaporizes.

How Does the pH of Coffee Impact its Aroma and Taste?

Coffee beans are actually seeds that are found inside the fruit of a tropical evergreen shrub. After harvesting, coffee beans are then roasted, ground, and brewed to produce a beverage that is rich in aroma and flavor.

Given coffee’s natural state, it’s no surprise that it has an alkaline pH level, meaning it’s highly acidic. The pH level of coffee can range from 6.5 to 8, but the most common range is between 6.8 and 7.2. The higher the pH level, the more bitter the coffee will be, while the lower the pH level, the less bitter the coffee will be.

What Is the Boiling Point of Coffee in Celsius?

As we’ve mentioned, the boiling point of coffee varies depending on its pH level. But what does this mean in practical terms? The boiling point of coffee in Celsius is different based on its pH level. The higher the pH level, the lower the boiling point.

The lower the pH level, the higher the boiling point. Let’s take a look at some of the most common pH levels, along with their corresponding boiling points.

6.8 – 7.2 is an average pH level; the boiling point is 212 degrees Celsius.

6.5 – 6.8 is a slightly more acidic pH level; the boiling point is 205 degrees Celsius.

6.0 – 6.5 is more strongly acidic; the boiling point is 212 degrees Celsius.

5.5 – 6.0 is strongly acidic; the boiling point is 230 degrees Celsius.

5.0 – 5.5 is very strongly acidic; the boiling point is 266 degrees Celsius.

The Importance of Brewing Time

Coffee brewing time is also critical in determining its taste. While the ideal brewing time for coffee varies depending on the recipe you’re following, it’s generally recommended that you brew your coffee for around 4 minutes on average.

Now, you might be wondering, how does brewing time affect the taste of coffee? Well, once you finally reach the boiling point of coffee, the flavor of the coffee is fully extracted, meaning that the flavor is no longer increasing.

So if you’re brewing for less than 4 minutes, the flavor of your coffee won’t be fully extracted. This might not be a big deal if you’re brewing a single cup of coffee, but if you’re brewing a pot of coffee, you’ll definitely taste the difference. The coffee will likely taste sour because the flavor isn’t fully extracted.

The Importance of Water Quality

The pH level of your water directly affects the taste of your coffee. The more alkaline your water, the more bitter your coffee will taste. If your water is extremely alkaline, your coffee will taste extremely bitter. Meanwhile, if your water is extremely acidic, your coffee will taste sour.

The best solution is to use a water filter. Water filters remove minerals, chemicals, and other impurities from your water. This will help ensure your coffee has a balanced taste. If you’re drinking coffee at home, you can test the pH level of your water by purchasing pH strips from your local supermarket or drugstore.


All in all, the boiling point of coffee is the temperature at which it is completely dissolved when heated. It’s also important to know that the taste of coffee is affected by a number of factors, including pH level and brewing time.

If you want to make the most delicious coffee, you’ll need to keep these factors in mind while brewing it.
