Welcome to the world of homemade winemaking! Turning your home-grown grapes into delicious wine is a rewarding and enjoyable process. In this guide, we’ll take you through every step of the journey, from preparing your grapes to bottling the final product. Let’s get started!

Making wine at home is a time-honored tradition that combines science, art, and a bit of magic. It involves converting the sugars in grapes into alcohol through fermentation. With the right ingredients, equipment, and techniques, you can create a wine that rivals store-bought varieties.

Ingredients and Supplies

To begin, gather the following ingredients and supplies:

Ingredients

10kg (22lbs) of grapes
4.5kg sugar
Hedgerow Wine Kit or equivalent ingredients:
- 1g pectolase
- 1 sachet/5g yeast
- 5 tsp citric acid
- 2 tsp bentonite
- 1.5 tsp potassium sorbate
- 28g (1oz) isinglass
Campden tablets

Equipment

25-litre brewers bucket
6 demijohns or another fermentation bucket
Long-handled stirrer
Airlocks (one for each demijohn)
26 bottles with corks/screw caps
Funnel
Wine bottle corker
Hydrometer (optional but recommended)
Large pan

Step-by-Step Process

Step 1: Prepare Your Equipment

Sterilizing your equipment is crucial to avoid contamination. Wash all buckets, stirrers, and bottles with hot, soapy water. Rinse thoroughly and sterilize using Campden tablets dissolved in water (16 tablets per gallon/4.5l). Let the solution sit in the equipment for 20 minutes before draining.

Step 2: Check and Prepare the Grapes

Your grapes should be ripe but not overly sweet. Taste them to ensure they’re ready, or use a hydrometer to measure the specific gravity (SG), aiming for a reading between 1.070 and 1.100.

Wash your hands thoroughly before handling the grapes. Remove any stems, leaves, or moldy grapes, then crush them over a large pan or directly into the fermentation bucket to release the juice. Include the grape skins for added color and flavor.

Step 3: Initial Processing

Boil Water: Bring 10 liters of water to a boil. Pour the boiling water over the crushed grapes in the fermentation bucket. This helps to kill any bacteria and slightly cook the grapes, releasing more color and flavor.
Add Campden Tablets: Dissolve 5 Campden tablets in a small amount of boiling water and add to the bucket. Stir the mixture thoroughly.

Step 4: Add Sugar and Pectolase

Stir in 4.5kg of sugar until it is completely dissolved. This will increase the alcohol content of your wine. If you prefer a less sweet wine, you can adjust the amount of sugar accordingly. Add 1g of pectolase to break down the pectin in the fruit, ensuring a clearer wine.

Step 5: Fermentation Setup

Add Cold Water: After the sugar has dissolved, top up the bucket with cold water until you reach the 23-liter mark.
Sterilize the Stirrer: Boil the stirrer for a few minutes, then use it to mix the contents of the bucket.
Install the Airlock: Drill a hole in the bucket lid if necessary and insert the airlock. Fill the airlock with boiled water to prevent contamination while allowing CO2 to escape.

Step 6: Add Yeast and Nutrients

Once the mixture has cooled to room temperature (below 30°C), add the yeast, citric acid, and bentonite (clarifying agent). Stir well, reseal the bucket, and ensure the airlock is properly installed. Leave the mixture to ferment at room temperature for about two weeks or until the bubbling slows significantly.

Step 7: Strain and Stabilize the Wine

Strain the Mixture: Use a sterilized jug to pour the fermented mixture through a sterilized fruit net into another cleaned and sterilized bucket. Press the net to extract as much liquid as possible.
Add Potassium Sorbate: Add 1.5 teaspoons of potassium sorbate to stabilize the wine, preventing further fermentation. Stir well.

Step 8: Clarification

Add Finings: Add 28g of isinglass or follow the instructions for any other fining agents you use. Stir thoroughly and leave the mixture to sit for one day.
Add Second Finings: If using a two-step fining process, add the second finings as per instructions and stir carefully for 15 seconds.

Step 9: Maturation

Leave the wine to mature in the bucket for about three weeks. During this time, taste the wine periodically to monitor its development. If it tastes too acidic, let it stand longer to allow CO2 to escape naturally.

Step 10: Prepare the Bottles

Clean the Bottles: Soak bottles in hot, soapy water to remove labels. Rinse thoroughly and use a bottle brush if needed.
Sterilize the Bottles: Fill the bottles with a Campden tablet solution (16 tablets per gallon of water) and let them stand for 15 minutes. Drain and do not rinse.

Step 11: Bottling the Wine

Siphon the Wine: Place the bucket on a raised surface and use sterilized tubing to siphon the wine into the bottles. Leave a small air gap at the top of each bottle.
Seal the Bottles: If using corks, soften them by soaking in hot water, then use a bottle corker to insert them into the bottles. For screw caps, ensure they are tightly sealed.

Step 12: Storage and Aging

Store the bottles in a cool, dark place. While the wine can be enjoyed immediately, aging it for several months will enhance its flavor.

Tips for Success

Sterilization

Keeping everything clean and sterilized is key to preventing unwanted bacteria from spoiling your wine. Wash your hands frequently during the process.

Monitoring Fermentation

Using a hydrometer to measure specific gravity can help you track the fermentation process and ensure your wine reaches the desired alcohol content.

Taste Testing

Regularly taste your wine during the maturation process to ensure it is developing the flavors you desire. Adjustments can be made by adding sugar or acid as needed.

Troubleshooting

Fermentation Not Starting

If fermentation does not begin, check that the temperature is within the optimal range for your yeast strain. If it’s too cold, move the bucket to a warmer area.

Wine Tastes Off

If the wine tastes off, it could be due to contamination or an imbalance in sugar and acid. Always ensure everything is sterilized and follow the recipe closely.

Cloudy Wine

Cloudiness can result from insufficient fining or pectolase. Adding additional fining agents and allowing the wine to settle longer can help clarify it.

Conclusion

Making your own grape wine at home is a rewarding experience that combines patience, precision, and creativity. With the right ingredients, equipment, and careful attention to detail, you can produce a delicious homemade wine that you’ll be proud to share with friends and family.
