Clearing wine with eggshells is a traditional method that has been used for centuries. It is a natural and effective way to clarify wine, removing any sediment or cloudiness that may have developed during the fermentation process.
This technique involves adding eggshells to the wine, which bind to the sediment and cause it to settle to the bottom of the container.
I leave it up to you to decide if this is the best way to clear your wine as I described in a separate article.

To begin the process, start by collecting eggshells. You will need approximately one eggshell per gallon of wine.
Rinse the eggshells thoroughly with water to remove any remaining egg white or yolk.
Once the eggshells are clean, crush them into small pieces using a mortar and pestle or a rolling pin. The smaller the pieces, the more surface area they will have and the more effective they will be at clarifying the wine.
The Role of Eggshells in Wine Clearing
As a winemaker, I have experimented with various techniques to clear wine; one proven effective method is using eggshells. Eggshells are a natural fining agent that can help clarify wine by removing unwanted particles.
When eggshells are added to wine, they react with the tannins and other impurities in the wine, causing them to bind together and settle to the bottom of the container. This process is called flocculation.
To use eggshells as a fining agent, you will need to clean and crush them into small pieces. Then, add them to the wine and stir gently. Allow the wine to sit for a few days, and the eggshells will settle to the bottom, taking the impurities with them.
It is important to note that using eggshells to clear wine can affect the taste and aroma of the wine. Therefore, it is recommended to use this method only for wines that have strong flavors and aromas that can withstand the changes.
In conclusion, eggshells can be an effective and natural way to clear wine. However, it is important to use this method with caution and only for wines that can handle the changes in taste and aroma.
Preparing the Eggshells
To clear wine with eggshells, the first step is to prepare the eggshells. This is a crucial step that requires attention to detail. Here are the steps I follow:
- Gather the eggshells: I collect eggshells from eggs that have been used in cooking. I rinse them with water to remove any residue and let them dry.
- Crush the eggshells: Once the eggshells are dry, I crush them into small pieces using a mortar and pestle. The pieces should be small enough to fit through a funnel.
- Sterilize the eggshells: I sterilize the eggshells by boiling them in water for 10 minutes. This ensures that any bacteria or germs on the shells are killed.
- Dry the eggshells: After boiling, I drain them and let them dry completely. This usually takes a few hours.
By following these steps, the eggshells are ready to be used to clear wine. It’s important to note that the eggshells should be prepared just before they are needed. This ensures that they are fresh and have not been contaminated.
Adding Eggshells to the Wine
To clear wine with eggshells, the first step is to collect the eggshells. You will need about 5-6 eggshells per gallon of wine. Rinse the eggshells thoroughly with water and let them dry completely. Once the eggshells are dry, crush them into small pieces using a mortar and pestle or a rolling pin.
Next, add the crushed eggshells to the wine. You can do this by placing the eggshells in a cheesecloth and tying it up, or by simply adding the crushed eggshells directly to the wine. Stir the wine gently to distribute the eggshells evenly.
Let the wine sit for about a week to allow the eggshells to settle to the bottom of the container. Once the eggshells have settled, you can rack the wine off of them, leaving the sediment behind. Repeat this process if necessary until the wine is clear.
It is important to note that adding eggshells to wine can affect the flavor profile. The eggshells can add a subtle mineral taste to the wine, which can be desirable in some cases but not in others. It is recommended to test a small batch before adding eggshells to a larger batch of wine.
In addition to clearing the wine, eggshells can also help to reduce the acidity of the wine. The calcium carbonate in the eggshells reacts with the acid in the wine, resulting in a smoother, less tart taste. This can be particularly useful for wines made from high-acid grapes.
Overall, adding eggshells to wine is a simple and effective way to clarify the wine and reduce its acidity. With a little bit of experimentation, you can find the right amount of eggshells to use to achieve the desired taste and clarity.
Monitoring the Clearing Process
During the clearing process, it’s important to monitor the wine regularly to ensure it’s progressing as expected. Here are some tips for monitoring the clearing process:
- Check the clarity: After a few days, check the clarity of the wine by holding it up to a light source. If it’s still cloudy, give it more time to settle. If it’s clear, move on to the next step.
- Smell the wine: Take a whiff of the wine to ensure there are no off-smells or funky aromas. If you detect any unpleasant odors, it could be a sign of spoilage or contamination.
- Taste the wine: After a few days, taste the wine to see if it’s developing the desired flavor profile. If it’s not quite there yet, give it more time to clear.
- Monitor the sediment: As the wine clears, sediment will settle at the bottom of the container. Check the sediment regularly to see if it’s compacting and settling properly. If it’s not, gently stir the wine to encourage settling.
By monitoring the clearing process, you can ensure that your wine is developing properly and avoid any potential issues.
Removing the Eggshells
After adding eggshells to the wine, it is important to remove them before bottling. The eggshells will settle at the bottom of the container, so it is necessary to carefully siphon the clear wine off the top of the sediment.
To do this, I use a siphon tube and a clean container. I carefully insert the tube into the wine, being careful not to disturb the sediment. Then, I suck on the other end of the tube to start the flow of wine. Once the wine starts flowing, I quickly transfer the tube to the clean container.
It is important to not let the siphon suck up any of the sediment, as this will cloud the wine. If any sediment is accidentally transferred, it can be removed by filtering the wine through a fine mesh strainer or cheesecloth.
After removing the wine, I discard the sediment and rinse out the container before returning the clear wine to it. The wine can then be bottled and stored as desired.
I found a video that explains and shows the whole process.
The Aftermath: Assessing the Wine
After clearing wine with eggshells, it is important to assess the quality of the wine. Here are some tips on what to look for:
- Clarity: One of the main reasons for using eggshells to clear wine is to improve its clarity. After the process is complete, the wine should be noticeably clearer than before. Hold the glass up to the light and check for any cloudiness or sediment.
- Color: The color of the wine should not be affected by the eggshell-clearing process. If you notice any color changes, it could be a sign of oxidation or other issues.
- Aroma: The aroma of the wine should be clean and free of any off-putting scents. Take a sniff and look for any hints of vinegar, mold, or other unpleasant odors.
- Taste: Finally, taste the wine to assess its flavor. It should be smooth and balanced, with no harsh or bitter notes. If you detect any unwanted flavors, it could be a sign of contamination or spoilage.
Overall, clearing wine with eggshells can be an effective way to improve its clarity and quality. However, it is important to carefully assess the wine after the process to ensure that it is still drinkable and enjoyable.
Troubleshooting Common Issues
As with any winemaking process, there are a few common issues that may arise when using eggshells to clear wine. Here are some troubleshooting tips to help you overcome these issues:
If your wine remains cloudy after using eggshells to clarify it, there are a few possible reasons why this may be happening. Firstly, you may not have used enough eggshells. As a general rule, you should use one eggshell per gallon of wine. If you have used less than this, you may need to add more eggshells to achieve the desired clarity.
Another possible reason for cloudy wine is that the eggshells were not crushed finely enough. To prevent this, make sure to grind the eggshells into a fine powder before adding them to the wine. You can do this by using a mortar and pestle or a food processor.
If your wine has an unpleasant smell after using eggshells to clarify it, this may be due to the eggshells not being properly sanitized. To avoid this issue, make sure to thoroughly clean and sanitize the eggshells before using them. You can do this by boiling them in water for a few minutes or by soaking them in a solution of water and sanitizing solution.
Another possible reason for the unpleasant smell is that the eggshells were left in the wine for too long. To prevent this, make sure to remove the eggshells from the wine after 24-48 hours.
Sediment in the Bottle
If you notice sediment in the bottom of your wine bottles after using eggshells to clarify it, this is likely due to the wine not being properly racked before bottling. To prevent this, make sure to rack the wine at least once before bottling to remove any sediment that may have settled at the bottom.
Overall, using eggshells to clear wine can be an effective and natural method. However, it is important to troubleshoot any issues that may arise to ensure that your wine is of the highest quality.
When using eggshells to clear wine, it is important to take certain safety precautions to ensure that the process goes smoothly and there are no risks to your health.
Here are a few things to keep in mind:
- Wash your hands thoroughly before handling the eggshells and the wine. This will help prevent the spread of bacteria and other harmful substances.
- Use only fresh, clean eggshells. Do not use eggshells that have been sitting around for a long time or that have been exposed to dirt or other contaminants.
- Make sure that the eggshells are crushed into very small pieces before adding them to the wine. This will help prevent any large pieces from getting into the wine and causing harm.
- Do not use eggshells if you have an egg allergy. Even small amounts of eggs can cause a severe allergic reaction in some people.
- Be careful when handling the wine after adding the eggshells. The wine may be more delicate and prone to spoilage, so it’s important to handle it with care.
By following these simple safety precautions, you can ensure that your eggshell wine-clearing process goes smoothly and safely.
