How to wash a demijohn of wine

A is a large glass container used for fermenting and aging wine. It is important to a demijohn thoroughly before and after each use to maintain the quality and flavor of the wine. Proper cleaning of a demijohn ensures that no residual flavors or bacteria remain, which could contaminate future batches of wine. In this article, we will guide you on how to effectively wash a demijohn of wine.

1. Gathering the Supplies
Before starting the cleaning process, gather all the necessary supplies. This includes hot water, a long-handled brush specifically designed for cleaning demijohns, dish soap, and a cleaning agent like sodium metabisulfite or chlorine dioxide (determined by the type of wine residue).

2. Preparing the Cleaning Solution
Fill the demijohn with hot water, making sure to cover the entire interior surface. Add a few drops of dish soap to the water and mix it gently until it creates a soapy solution. If dealing with a stubborn residue or stain, prepare a cleaning agent solution as directed on the packaging.

3. Scrubbing the Interior Surface
Using a long-handled brush, carefully scrub the interior surface of the demijohn. Pay close attention to the bottom, neck, and sides, as these areas tend to accumulate the most residue. Apply firm but gentle pressure to ensure all residue is removed. If dealing with tough stains, let the cleaning solution sit in the demijohn for a few minutes before scrubbing.

4. Rinsing Thoroughly
After scrubbing, rinse the demijohn several times with hot water. Make sure to remove all the soap or cleaning agent residue, as they can affect the taste and quality of the wine. A handy tip is to fill the demijohn with water, close it securely with the airlock or stopper, and shake it vigorously to dislodge any remaining residue.

5. Sanitizing the Demijohn
To ensure that any potential bacteria or contaminants are eliminated, sanitize the demijohn using an appropriate cleaning agent. One option is to immerse the demijohn in a sanitizing solution, such as a mixture of sodium metabisulfite and water, following the instructions on the packaging. Another option is to use a chlorine dioxide solution to sanitize the container. Thoroughly rinse the demijohn after sanitization.

6. Drying the Demijohn
Once the demijohn is clean and sanitized, allow it to air dry completely. Placing it upside down on a clean dish rack or towel will help drain any remaining water. Ensure that all moisture is gone before storing the demijohn to prevent the growth of mold or mildew.

7. Storage and Maintenance
Store the demijohn in a cool, dry place away from direct sunlight. To maintain its cleanliness, avoid letting the demijohn sit empty for long periods. If not in use, consider storing it filled with a sanitizing solution to prevent any bacterial growth.

Remember, cleaning and sanitizing a demijohn of wine is an essential step in winemaking. By following these steps, you can ensure the quality of your wine is not compromised by lingering residue or bacteria. So, go ahead and wash your demijohn, and enjoy making your next batch of delicious homemade wine!
