Many coffee enthusiasts believe brewing temperature is the key to achieving the perfect cup of coffee. However, not all coffee tastes the same, and one factor that plays a crucial role in the taste of your coffee is the brewing temperature. 

But, with so many home coffee machines available in the market, how do you know what temperature to brew your coffee at? 

In this blog post, we’ll discuss the impact of temperature on coffee extraction, how different brewing methods affect temperature and tips for achieving the ideal temperature for your home coffee machine.

Let’s get started!

The Perfect Coffee Brewing Temperature

The perfect brewing temperature for coffee can vary depending on several factors, such as the roast level, bean origin, and brewing method. However, a broad range of temperatures is optimal for most coffee brewing.

The ideal temperature for brewing coffee is between 195-205°F (90-96°C). This temperature range allows for optimal extraction of the coffee grounds without scorching or burning them, resulting in a flavourful and balanced cup of coffee.

Generally, light, medium, and dark roast coffees require different brewing temperatures to achieve the best flavour and aroma.

  • For light roast coffee, known for its delicate and subtle flavours, a brewing temperature of around 195-200°F (90-93°C) is recommended. This temperature range allows the coffee’s nuanced flavours to shine without being overpowered by a higher brewing temperature.
  • For medium roast coffee with a more balanced flavour profile, a brewing temperature of around 200-205°F (93-96°C) is recommended. This temperature range helps to extract the coffee’s full range of flavours without burning or scorching the beans.
  • For dark roast coffee, known for its bold and rich flavour, a brewing temperature of around 205°F (96°C) is recommended. This higher temperature helps bring out the coffee’s rich and intense flavours while maintaining balance and avoiding bitterness.

In addition to selecting the appropriate temperature for your brewing method, it’s crucial to ensure that your coffee machine is calibrated correctly to maintain a consistent brewing temperature. Consistency is key to achieving the perfect cup of coffee every time.

What Happens If You Brew at the Wrong Temperature?

Brewing coffee at the wrong temperature can result in a less-than-ideal cup.

Brewing at too low a temperature can result in under-extraction, where the coffee may taste weak and lack flavour. This is because the lower temperature may need to be increased to extract the full range of flavours and aromas from the coffee grounds.

On the other hand, brewing at too high a temperature can lead to over-extraction, where the coffee can taste bitter and burnt. The higher temperature may cause the coffee to be over-extracted, resulting in an unbalanced and unpleasant flavour profile.

Additionally, inconsistent brewing temperatures can lead to inconsistent flavour and quality in your coffee. Water temperature in the coffee machine that fluctuates during brewing may cause the coffee to taste different from one cup to the next.

Tips for Achieving the Ideal Temperature for Your Home Coffee Machine

To ensure that your home coffee machine is brewing coffee at the ideal temperature, here are several steps you can take:

Read the manufacturer’s instructions

The manufacturer’s instructions for your coffee machine should indicate the recommended brewing temperature. Be sure to follow these instructions to achieve the optimal temperature for your machine.

Use a thermometer

Using a thermometer to measure the water temperature during brewing will help ensure it is within the optimal range for specific brewing methods and coffee roast levels.

Preheat your coffee machine

Preheating your coffee machine can help ensure that the brewing water is at the optimal temperature. To warm it up, run a hot water cycle through the machine before brewing.

Use fresh, cold water

Start with fresh, cold water when brewing coffee. Water sitting in the machine or a reservoir for an extended period may not be at the optimal temperature.

Adjust brewing time

Consider adjusting your brewing time if your coffee is consistently over or under-extracted. Longer brew times can compensate for lower temperatures, while shorter brew times can help mitigate higher temperatures.

Experiment with different temperatures

Depending on your coffee roast level and personal taste preferences, you may find that a slightly higher or lower temperature than the optimal range works better. Experimenting with different temperatures can help you find the ideal brewing temperature for your perfect cup of coffee.

Following these tips can help ensure that your home coffee machine is brewing coffee at the ideal temperature for your specific brewing method and coffee roast level, resulting in a delicious and balanced cup of coffee.


Understanding the role of brewing temperature in home coffee machines is crucial to achieving the perfect cup of coffee. With the right temperature, you can bring out the unique flavours and aromas of your favourite coffee beans and ensure that every cup is consistent and delicious.
