Watermelon Wine: Exploring the Unique Flavor and Benefits of This Summer Drink

Watermelon wine, a light, sweet fermented beverage, is the perfect summer treat for those who appreciate a unique and fruity flavor. Made from ripe and juicy watermelons, this wine captures the essence of late spring and early summer when the fruit peaks.

During the wine-making process, you will cook down the fruit of the watermelon and ferment the juice, eventually transferring it through a series of racks over time. The key to producing the best watermelon wine lies in striking the right balance between delicate flavor and sweetness; this can be a tricky challenge but one well worth the effort. As you learn the craft, draw inspiration from the variety of watermelon wine recipes available and adapt them to suit your preferences.

What is Watermelon Wine

Watermelon wine is a light and fruity-tasting alcoholic beverage made from the fermentation of ripe watermelon. Perfect for those hot summer days, this wine provides a refreshing alternative to traditional grape-based wines.

The process of making watermelon wine is quite simple. Start by choosing a ripe watermelon, as this will give the best flavor to your wine. Once you have selected the perfect fruit, you must crush and ferment its flesh. During fermentation, the watermelon’s natural sugars will transform into alcohol, creating a drink that can range from pink to deep red in color.

Watermelon wine typically has a low alcohol content, hovering around 10% ABV. This makes it ideal for casual sipping or as a base for delicious and innovative summer cocktails.

Historically, watermelon wine has been enjoyed for centuries, with mentions of its creation dating back to the Old Testament. Today, it’s increasingly popular among homebrewers, who appreciate its unique flavor and straightforward production process.

Watermelon Wine Recipe


To make watermelon wine, you will need the following ingredients:

10 pounds of ripe, red watermelon (with seeds removed)
2.5 pounds of sugar
1 gallon of water
1 teaspoon of acid blend (or as directed by the brand)
1 package of wine yeast
1 campden tablet (optional for preserving)


The following equipment will be necessary for making your homemade watermelon wine:

A large pot or fermentation container
A strainer or cheesecloth
A one-gallon carboy (glass or plastic)
An airlock and bung
A hydrometer or refractometer (to measure alcohol content)
Siphon tubing
Bottles and corks (or caps)

Watermelon Wine-Making Instructions:

1) Start by selecting a fresh, ripe watermelon. To ensure the juiciest and sweetest result, choose a watermelon that is in season and has a deep red color. Cut the watermelon into chunks, and remove the rind and seeds.

2) Place the watermelon chunks in a large pot, and turn the heat to medium. Cook the watermelon until it liquefies. While it heats, mash the pieces to release more juice. After the watermelon has broken down, remove it from the heat and let it cool.

3) Mix the cooled watermelon juice with sugar, water, and acid blend in a fermenting container. Ensure the sugar and acid blend fully dissolve to achieve a balanced flavor. Add the wine yeast and, optionally, the Campden tablet to prevent spoilage.

4) Cover the fermentation container with a towel or airlock and allow the mixture to ferment for at least one week, or until the hydrometer indicates that your desired alcohol content is achieved. Check the fermentation daily to prevent any overflow.

5) Once the fermentation is complete, use a siphon tube to transfer the wine to a one-gallon carboy, leaving sediment behind. Attach the airlock and bung to the top of the carboy.

6) Allow the wine to clear for about three weeks before bottling. When bottling, ensure the bottles are properly cleaned and sanitized, and use corks or caps to seal your fresh, homemade watermelon wine.

Preparation and Fermentation

Preparing the Watermelon

Start by choosing a large, ripe watermelon. Cut the watermelon and remove the flesh from the center, discarding any skin. Chop the flesh into chunks, but don’t worry about the seeds. You’ll want about 15 lbs of juicy watermelon flesh for this recipe.

Mixing Ingredients

Heat half of the water and 9 lbs of white granulated sugar in a large pot. Bring it to a boil for a few minutes, stirring until the sugar dissolves. This sweet mixture will provide the necessary base for fermentation. Measure about 14-15 cups (3.5 liters) of watermelon juice from the chopped fruit, straining the seeds out as you go.

Add sugar to the strained watermelon juice. Then, mix in the following ingredients:

2 tbsp Yeast Nutrient
1/2 tsp Pectic Enzyme
2 1/2 tbsp Acid Blend
1 1/2 tsp Wine Tannin

The acid blend, tannin, and yeast nutrients will ensure a balanced, flavorful wine. Finally, add a packet of wine yeast, such as Pasteur Champagne yeast, to initiate fermentation.

Fermentation Process

Transfer your mixture into a fermentation bucket. Primary fermentation will occur over the next few days, during which the yeast will consume the sugar and create alcohol. Keep a close watch on the temperature, maintaining a chilled environment for proper fermentation.

As the primary fermentation progresses, you may notice sediment forming at the bottom of the bucket. This is normal. After 5-7 days, when the vigorous fermentation subsides, it’s time to move on to secondary fermentation.

Transfer the wine to a secondary fermenter using a siphon, leaving the sediment behind. You can also add 1 finely crushed and dissolved Campden tablet at this stage. Attach an airlock to allow the gases to escape while keeping contaminants out. The secondary fermentation will be slower and may last for several weeks.

During this period, it’s important to “rack” the wine occasionally, which means transferring the liquid to a new container, leaving any sediment behind. This will help clarify the wine and improve its flavor.

Once the fermentation process is complete, your watermelon wine will have an ABV (alcohol by volume) of around 10-12%. Bottle your wine and enjoy it chilled on a warm summer night.

Testing and Adjusting

Taste and Sweetness

When testing your watermelon wine, check for sweetness and taste. Typically, watermelon has a sweet, honeyed flavor, which should be retained in the wine. To determine the level of sweetness, use a hydrometer to measure specific gravity. If your wine isn’t sweet enough, you can back-sweeten it by adding sugar or honey. Test and adjust according to your preference until you achieve the desired sweetness.

Acidity and Tannin Balance

For the wine to have a balanced flavor profile, consider its acidity and tannin levels. Use an acid test kit to measure the acidity of your wine. If the acidity is too low, you can use an acid blend to adjust it. As for tannin, taste the wine and observe its mouthfeel. If it’s too astringent, add more liquid like water or juice or subtly back sweeten to balance the tannins. On the other hand, if the wine lacks structure, you might want to add some tannin powder.

Alcohol Content

Monitoring the alcohol content in your watermelon wine is essential. To do so, take hydrometer readings at various stages: before fermentation, every few days during fermentation, and after fermentation has finished. Compare the starting and ending hydrometer readings to calculate the alcohol content accurately.

Remember that throughout this process, your main goal is to balance flavor, acidity, and sweetness to your liking. By meticulously testing and adjusting your watermelon wine, you’re on your way to creating a delicious, unique wine.

Bottling and Aging

Racking and Clearing

Before bottling your watermelon wine, it is essential to rack the wine to ensure its clarity. Racking is the process of transferring the wine from one container to another, leaving the sediment behind. Use a glass carboy for racking, as it is ideal for visual monitoring and better protection against oxygen and contaminants than other containers. To avoid a tornado effect, introduce the siphoning tube at an angle along the carboy’s sides, minimizing the exposure of your wine to air.

During the clearing process, closely observe the wine’s color and stability. Watermelon wine can have a delicate flavor, and preserving its natural color is crucial for the final result. Be patient and take your time, allowing the wine to clear naturally.

Bottling the Wine

Once your watermelon wine has achieved optimal clarity, it’s time to bottle it. Always use sanitized equipment such as a stem-and-valve bottle filler or a bottling wand to ensure cleanliness.

Some key points to consider during bottling are:

– Ideally, fill 30 standard 750-mL bottles for a 5-gallon (19-L) batch.
– Place the filled bottles in a cool, dark environment to minimize exposure to light and temperature fluctuations.
– Properly seal the bottles with either cork or screw caps, ensuring an airtight seal to prevent oxidation.

Aging the Wine

Though watermelon wine might not have the same aging potential as grape wines or mead, it is still important to allow it to age to enhance its flavors and aroma.

Here are a few guidelines for aging your watermelon wine:

– Age the wine for at least six months before opening the first bottle. This period will give the wine sufficient time to mature and develop its unique characteristics.

– Store the aging wine in a consistent and cool environment, ideally at a temperature between 55°F (13°C) and 60°F (15°C), with a humidity level of approximately 70%.

– Consume your watermelon wine within three to four years, as it typically lacks the natural acidity, tannin, and phenolic content found in grape wines that can withstand longer aging periods.

Additional Tips and Tricks

Alternative Ingredients

In addition to sugar, you can use alternative sweeteners like honey or raisins to add a unique flavor to your watermelon wine. If you decide to use honey, make sure it has been fully dissolved in the watermelon juice before adding the yeast. Adding a little extra water to help dilute the honey for better fermentation may also be a good idea.

When using raisins, finely chop them and add them directly to your fermentation container. Secure a cheesecloth or fine mesh strainer around the opening to prevent fruit flies and other contaminants from entering during fermentation.

Trying Other Melons

Watermelon isn’t the only fruit you can use for making melon-based wines. Cantaloupe, honeydew, and other melons can also yield delicious results. The process of making wine from these fruits is similar to that of watermelon wine. Be sure to remove the rind and seeds, and then cut the fruit into cubes or blend into a pulp before adding sugar or other sweeteners.

Different Yeast Types

While many recipes recommend using wine yeast for making watermelon wine, you can also experiment with different types of yeast, such as bread yeast. Remember that the yeast you choose will affect the flavor and alcoholic content of your finished beverage. Some yeast strains may cause more foaming or require a more extended fermentation period than others.

If you’re unsure which yeast to use, consult a local homebrew supply store or search on Amazon for additional information and product reviews. Remember that yeast plays a crucial role in turning your watermelon wine into the desired alcoholic beverage, so do your research and choose wisely.

In addition to selecting the right yeast, you may also want to involve other additives like pectic enzyme and wine tannin to improve the clarity and mouthfeel of your wine. While not necessary, these ingredients can enhance your homemade watermelon wine’s overall quality and results.

Lastly, don’t forget to use potassium sorbate to stabilize your wine after fermentation. This will help prevent any additional fermentation and preserve the flavor and alcohol content of your watermelon wine.
