Coffee lovers around the world enjoy their daily cup of joe for its rich and distinct flavors. However, there are times when your V60 coffee turns out to be bitter, leaving you puzzled and disappointed. What could be the reason behind this unpleasant taste? In this article, I will explore the common factors that might affect the taste of your V60 coffee and delve into why it might end up being bitter.
Brewing Variables: Temperature, Grind Size, and Brew Time
When it comes to brewing coffee, three crucial variables can significantly impact the taste: temperature, grind size, and brew time. Let’s understand how these factors might influence the bitterness of your V60 coffee.
Temperature
The water temperature plays a vital role in extracting the desired flavors from your coffee grounds. If the water is too hot, it can result in over-extraction, leading to a bitter taste. Conversely, if the water is too cold, it may not extract enough flavor, resulting in a weak and underwhelming cup.
To avoid bitterness caused by incorrect water temperature, ensure that you aim for a water temperature between 195-205°F (90-96°C). Investing in a good kettle with a thermometer can help you achieve the desired temperature consistently.
Grind Size
The grind size of your coffee beans can significantly affect the extraction process. If the grind is too fine, the water might struggle to flow through the coffee grounds, resulting in over-extraction and bitterness. On the other hand, if the grind is too coarse, the water may pass through too quickly, leading to under-extraction and a weak flavor profile.
For V60 brewing, a medium-fine grind is usually recommended. However, finding the ideal grind size may require some experimentation. Adjusting the grind size slightly finer or coarser can help you dial in the perfect balance of flavors and minimize bitterness.
Brew Time
The brew time refers to the duration it takes for the water to come in contact with the coffee grounds during the brewing process. If the brew time is too short, the coffee may be under-extracted, resulting in a weak and sour taste. Conversely, if the brew time is too long, over-extraction can occur, leading to bitterness.
When using a V60, the ideal brew time is usually between 2-3 minutes. However, factors such as grind size and coffee freshness can influence this timeframe. Adjusting the brew time can help you fine-tune the taste of your coffee and reduce bitterness.
Coffee-to-Water Ratio: Finding the Right Balance
Another factor that can impact the taste of your V60 coffee is the coffee-to-water ratio. Achieving the right balance is crucial for a well-balanced and flavorful cup. Using too little coffee in proportion to the amount of water can result in a weak and watery brew, while using too much coffee can make the coffee taste overly bitter and intense.
A common guideline for V60 brewing is a ratio of 1:16, where 1 gram of coffee is used for every 16 grams of water. However, personal preferences vary, and some coffee enthusiasts prefer a stronger or milder cup. Experimenting with different ratios can help you find the optimal balance that suits your taste buds and minimizes bitterness.

Coffee Beans: Quality and Freshness
The quality and freshness of your coffee beans can significantly impact the taste of your V60 brew. Low-quality or stale beans may have already begun to oxidize, resulting in a bitter and unpleasant flavor. Opting for freshly roasted beans with a reputable source can make a world of difference in the taste of your coffee.
Consider purchasing whole bean coffee and grinding it just before brewing for the best possible flavor. Look for a roast date on the packaging, and aim to use the beans within a few weeks of the roast date for optimal freshness.
Water Quality
The water you use for brewing can also impact the taste of your V60 coffee. If your tap water has impurities or a strong taste, it can alter the flavor profile of your brew. Hard water, for example, can result in a more pronounced bitterness.
Using filtered water or investing in a water filter system can help improve the taste of your coffee. Filtered water removes any impurities and ensures a cleaner and more pleasant flavor in your brew.
Brewing Technique: Consistency and Precision
Lastly, your brewing technique plays a crucial role in determining the taste of your V60 coffee. Consistency and precision are key to achieving a balanced and flavorful cup. Inconsistent pouring speeds or uneven distribution of water over the coffee grounds can lead to inconsistent extraction and bitterness.
Instead, focus on achieving a slow, steady pour, ensuring that the water covers all the coffee evenly. Pour in a circular motion, starting from the center and moving towards the outer edges, maintaining a consistent flow rate. With practice and attention to detail, you can refine your brewing technique and create a consistently delicious cup of V60 coffee.
To summarize, several factors can contribute to the bitterness of your V60 coffee. Paying attention to brewing variables such as temperature, grind size, and brew time can help you avoid over-extraction and bitterness. Finding the right coffee-to-water ratio, using high-quality beans, ensuring water quality, and refining your brewing technique can further enhance the taste of your brew. With patience, experimentation, and a passion for great coffee, you can unlock the full potential of your V60 and enjoy a perfectly balanced and flavorful cup every time.
