As coffee lovers, we’re always on the lookout for ways to improve our daily cup. From experimenting with different roasts to trying out new brewing methods, there’s no shortage of techniques to explore. One method that’s gained popularity in recent years is adding eggshells to coffee grounds. But what does this unusual practice actually do, and is it worth trying? In this article, we’ll delve into the world of eggshell-infused coffee and explore its benefits, drawbacks, and everything in between.
What’s the Science Behind Adding Eggshells to Coffee Grounds?
Before we dive into the benefits of adding eggshells to coffee grounds, let’s take a look at the science behind this practice. Eggshells are primarily composed of calcium carbonate, a naturally occurring mineral that’s also found in many types of rocks and shells. When added to coffee grounds, the calcium carbonate in eggshells can help to neutralize acidic compounds and balance out the pH level of the coffee.
How Does Calcium Carbonate Affect Coffee?
Calcium carbonate has a number of effects on coffee, including:
- Neutralizing acidity: Calcium carbonate can help to neutralize acidic compounds in coffee, resulting in a smoother, less bitter flavor.
- Reducing bitterness: By balancing out the pH level of the coffee, calcium carbonate can also help to reduce bitterness and create a more balanced flavor profile.
- Enhancing flavor: Some coffee enthusiasts claim that adding eggshells to coffee grounds can enhance the flavor of the coffee, bringing out subtle notes and nuances that might otherwise be lost.
Benefits of Adding Eggshells to Coffee Grounds
So, what are the benefits of adding eggshells to coffee grounds? Here are a few:
- Improved flavor: As mentioned earlier, adding eggshells to coffee grounds can help to balance out the pH level of the coffee, resulting in a smoother, more balanced flavor.
- Reduced acidity: If you’re sensitive to acidic coffee, adding eggshells can help to neutralize those acidic compounds and create a more comfortable drinking experience.
- Increased sustainability: Using eggshells in your coffee is a great way to reduce waste and create a more sustainable coffee routine.
Other Uses for Eggshells in Coffee
In addition to adding eggshells to coffee grounds, there are a few other ways to use eggshells in your coffee routine:
- As a natural water filter: Eggshells can be used as a natural filter to remove impurities from water, resulting in a cleaner, more flavorful cup of coffee.
- As a coffee grinder cleaner: Eggshells can be used to clean and descale coffee grinders, helping to remove old coffee oils and residue.
Drawbacks of Adding Eggshells to Coffee Grounds
While adding eggshells to coffee grounds can have a number of benefits, there are also some potential drawbacks to consider:
- Texture and sediment: Adding eggshells to coffee grounds can result in a slightly gritty or sediment-filled cup of coffee, which may not be appealing to everyone.
- Calcium buildup: If you’re using eggshells in your coffee regularly, there’s a risk of calcium buildup in your coffee equipment, which can lead to scaling and other problems.
Tips for Adding Eggshells to Coffee Grounds
If you’re interested in trying out eggshell-infused coffee, here are a few tips to keep in mind:
- Use clean, dry eggshells: Make sure to use clean, dry eggshells to avoid any contamination or bacterial growth.
- Grind the eggshells finely: Grind the eggshells finely to ensure they mix evenly with the coffee grounds.
- Start with a small amount: Start with a small amount of eggshells (about 1-2 shells per cup of coffee) and adjust to taste.
Conclusion
Adding eggshells to coffee grounds is a unique and intriguing practice that can have a number of benefits, from improving flavor to reducing acidity. While there are some potential drawbacks to consider, the benefits of eggshell-infused coffee make it well worth trying. Whether you’re a coffee connoisseur or just looking for a new way to mix things up, adding eggshells to your coffee grounds is definitely worth a shot.

What is the purpose of adding eggshells to coffee grounds?
Adding eggshells to coffee grounds is a technique used to improve the flavor and quality of brewed coffee. The eggshells help to neutralize the acidity of the coffee and add a smoother, more balanced taste. This method is especially useful for those who find their coffee too bitter or acidic.
The eggshells work by absorbing some of the acidic compounds present in the coffee, resulting in a more balanced flavor profile. This technique is often used by coffee aficionados who want to bring out the full flavor potential of their coffee beans. By adding eggshells to the coffee grounds, they can enjoy a more refined and nuanced cup of coffee.
How do I add eggshells to my coffee grounds?
To add eggshells to your coffee grounds, simply crush the eggshells into small pieces and mix them with the coffee grounds before brewing. The general ratio is to use about 1-2 eggshells per cup of coffee. You can adjust the amount to your taste, but this is a good starting point.
It’s essential to use clean and dry eggshells to avoid any contamination or bacterial growth. Make sure to rinse the eggshells thoroughly and dry them before crushing them. You can also store the crushed eggshells in an airtight container for later use.
Will adding eggshells affect the flavor of my coffee?
Adding eggshells to your coffee grounds can indeed affect the flavor of your coffee, but in a positive way. The eggshells will help to neutralize the acidity and bitterness, resulting in a smoother and more balanced taste. However, the flavor profile will still be determined by the type of coffee beans you use.
If you’re concerned about the flavor being affected, you can start by adding a small amount of eggshells and adjust to taste. Some people may not notice a significant difference, while others may find that it enhances the flavor of their coffee. Experiment with different ratios to find the perfect balance for your taste buds.
Can I use eggshells with any type of coffee beans?
Yes, you can use eggshells with any type of coffee beans. However, the effectiveness of the eggshells may vary depending on the type of beans and roast level. Lighter roasts tend to be more acidic, so the eggshells may have a more noticeable effect.
Darker roasts, on the other hand, may have a bolder flavor that can overpower the effect of the eggshells. Experiment with different types of coffee beans and roast levels to find the best combination for your taste preferences.
Are there any health benefits to adding eggshells to coffee?
There are no direct health benefits to adding eggshells to coffee. However, the eggshells can help to reduce the acidity of the coffee, which may be beneficial for people who experience heartburn or acid reflux after consuming coffee.
Additionally, some people believe that the calcium content in eggshells can help to neutralize the acidity of the coffee and provide a more balanced pH level. However, more research is needed to confirm this claim.
Can I reuse eggshells for multiple brews?
It’s not recommended to reuse eggshells for multiple brews. The eggshells can become saturated with the acidic compounds from the coffee, which can affect their ability to neutralize the acidity in subsequent brews.
Using fresh eggshells for each brew will ensure the best results and prevent any buildup of bacteria or contaminants. Simply crush new eggshells and mix them with the coffee grounds for each brew.
Is adding eggshells to coffee a common practice?
Adding eggshells to coffee is not a widely practiced technique, but it’s gaining popularity among coffee enthusiasts. Some specialty coffee shops and baristas use this method to create unique and balanced flavor profiles.
However, it’s not a traditional or common practice in most coffee-drinking cultures. The technique is often shared among coffee aficionados and online communities, where people experiment with different methods to improve the flavor of their coffee.
