Racking wine is a process of transferring wine from one container to another. It is typically done to remove sediment that has settled at the bottom of the container. Racking can also be used to blend different wines together or to add oxygen to the wine. It is an important part of winemaking and can have a significant impact on the flavor and quality of the wine.
The first step in racking wine is to siphon the wine from the old container into the new container. This can be done using a variety of methods, but the most common method is to use a siphon hose. A siphon hose is a long, flexible tube that is inserted into the old container and then used to suck the wine out of the container into the new container. It is important to insert the siphon hose into the wine below the surface of the wine so that you do not disturb the sediment.
Once the wine has been siphoned into the new container, you can then top off the container with fresh wine. This will help to prevent the wine from oxidizing. You can also add sulfites to the wine to help prevent spoilage. After the wine has been racked, it should be allowed to rest for a period of time before it is bottled. This will allow the wine to settle and the flavors to develop. The length of time that the wine needs to rest will vary depending on the type of wine.
Gathering Equipment
Bottles, Stoppers, and Caps
Choosing the right bottles, stoppers, and caps ensures the safe and proper storage of your wine. Select clean bottles designed for wine and avoid using any containers that have previously held chemicals or liquids that could contaminate your wine. Corks or synthetic stoppers provide an airtight seal to prevent oxidation, while capsules ensure a secure fit and protect the stoppers from contamination.
Racking Cane and Hose
A racking cane is a long, thin tube used to siphon wine from one container to another. It allows you to avoid disturbing the sediment settled at the bottom of the wine during fermentation. The hose attached to the racking cane should be made of a food-grade material that won’t impart any flavors or aromas to your wine.
Buckets or Carboys
Buckets or carboys serve as temporary containers during the racking process. They should be large enough to hold the volume of wine you’re transferring. Choose buckets made of food-grade plastic or stainless steel. Carboys are large glass or plastic containers commonly used in winemaking.
Auto-siphon or Pump
An auto-siphon is a device that uses gravity to transfer wine. It can be attached to the racking cane and hose to assist in the siphoning process. Alternatively, a pump can be used to move the wine more efficiently, especially for large volumes or distances.
Hydrometer and Thermometer
A hydrometer and thermometer are useful for monitoring the specific gravity and temperature of your wine during racking. Specific gravity helps determine the alcohol content, while temperature affects the viscosity of the wine and can influence the efficiency of racking.
Filter (Optional)
A filter can be used to remove any unwanted particles or impurities from your wine during the racking process. Choose a filter designed for wine filtration and ensure it’s food-grade and compatible with the type of wine you’re handling.
Selecting the Right Rack
Choosing the right rack for your wine depends on several factors, including the number of bottles you need to store, the type of wine you’re storing, and the space available in your home. Here are a few things to consider when selecting a wine rack:
Material
Wine racks are available in a variety of materials, including wood, metal, and plastic. Wood is a classic choice that can add a touch of elegance to your home. However, wood racks can be more expensive than other options. Metal racks are more durable and less likely to warp or crack over time. Plastic racks are the most affordable option, but they are not as durable or attractive as wood or metal racks.
Capacity
The capacity of a wine rack is measured in the number of bottles it can hold. Choose a rack that can accommodate the number of bottles you need to store, plus a few extra for growth. If you’re not sure how many bottles you need to store, start with a rack that holds 12-18 bottles. You can always add more racks later if you need to.
Size
The size of a wine rack is important if you have limited space in your home. Measure the space where you want to put the rack before you buy it. Make sure to allow for a few inches of clearance around the rack so that you can easily access the bottles.
Style
Wine racks come in a variety of styles, from traditional to modern. Choose a rack that matches the style of your home décor. If you’re not sure what style to choose, opt for a classic wine rack that will never go out of style.
Preparing the Wine
Before racking the wine, it is essential to prepare it properly. This involves several key steps:
Fining
Fining is a process of adding a substance to the wine that will cause the impurities and sediment to coagulate and settle to the bottom. This helps to clarify the wine and improve its appearance.
Common Fining Agents:
| Agent | Purpose |
|---|---|
| Gelatin | Removes tannins and other proteins |
| Isinglass | Fines white wines and helps remove haze |
| Bentonite | Removes excess protein and helps stabilize the wine |
Degassing
Degassing removes excess carbon dioxide from the wine. This is important to prevent oxidation and spoilage during storage.
Degassing Methods:
- Stirring or shaking the wine
- Using a vacuum pump
- Bubbling inert gas (e.g., nitrogen) through the wine
Stabilizing
Stabilization is the process of preventing the wine from undergoing further fermentation or spoilage. This can be achieved through methods such as:
Stabilization Techniques:
- Cold stabilization: Chilling the wine to precipitate tartrate crystals
- Chemical stabilization: Adding preservatives like sorbate or sulfite
- Biological stabilization: Treating the wine with enzymes or microorganisms
Cleaning the Rack
Cleaning the wine rack is an important step in the racking process. A clean rack will help to prevent the wine from becoming contaminated.
To clean the rack, you will need the following:
| Item | Quantity |
|---|---|
| Clean water | 1 gallon |
| White vinegar | 1 cup |
| Soft cloth | 1 |
Instructions:
1. Start by removing all of the wine bottles from the rack.
2. Rinse the rack thoroughly with clean water.
3. Add 1 cup of white vinegar to 1 gallon of water. Pour the vinegar solution over the rack and let it sit for 5 minutes.
4. Scrub the rack with a soft cloth. Be sure to get into all the nooks and crannies.
5. Rinse the rack thoroughly with clean water and allow it to dry completely before replacing the wine bottles.
By following these steps, you can ensure that your wine rack is clean and free of any contaminants.
Measuring and Marking the Placement
1. Determine the Height of the Spigot
The lowest hole in your barrel or tank should be the correct distance from the bottom to fill your bottles without leaving any sediment behind.
2. Mark the Spigot Hole
Measure the height of your bottles from the bottom to the top of the cork. Add an inch to account for any sediment that may settle at the bottom of the container.
3. Measure the Barrel or Tank
Determine the distance from the bottom of the barrel or tank to the surface of the wine. Subtract the measurement obtained in step 2.
4. Mark the Spigot Hole
Using a measuring tape or ruler, locate the distance obtained in step 3 on the outside of the barrel or tank. Mark this point with a pencil or chalk.
5. Determine Additional Spigot Holes
If you are using multiple spigots, you will need to determine the spacing between them. Consider the following factors:
- Number of bottles to be filled: The number of bottles you need to fill will determine how many spigots you will need.
- Size of the bottles: Larger bottles will require more time to fill, so you may need to space the spigots farther apart.
- Rate of flow: The flow rate of the spigots will also affect the spacing. Spigots with a faster flow rate can be spaced closer together.
As a general rule, spigots should be spaced at least 2 inches apart to allow for easy bottle filling and to prevent spills.
Here is a table summarizing the steps involved in measuring and marking the placement of spigots:
| Step | Action |
|---|---|
| 1 | Determine the height of the spigot. |
| 2 | Mark the spigot hole. |
| 3 | Measure the barrel or tank. |
| 4 | Mark the spigot hole. |
| 5 | Determine additional spigot holes. |
Inserting the Bottles
Once the bottles are ready, it’s time to insert them into the racking setup. Carefully insert the bottles into the holes on the top of the racking bench, ensuring that they are fully supported and won’t tip over.
When inserting the bottles, keep in mind the following considerations:
- Bottle Size and Shape: Different bottle sizes and shapes may require specific adjustments to the racking bench. Ensure that the bottles fit securely and won’t fall through.
- Bottle Clearance: Leave enough clearance between the bottles so that you can easily access the siphoning tube without accidentally bumping the bottles.
- Racking Tube: Insert the racking tube into the first bottle and lower it to the bottom of the vessel. Secure the tube in place using a rubber stopper or clip.
- Siphoning Tube: Insert the siphoning tube into the second bottle, placing its end just above the level of the sediment you want to remove.
- Siphon Priming: Prime the siphon by filling it with wine using a racking wand or syringe. Once primed, connect the free end of the siphoning tube to the receiving container.
- Siphon Control: Adjust the flow of the wine by controlling the height of the receiving container. By raising or lowering it, you can regulate the siphon’s suction and avoid oxidative damage to the wine.
| Element | Role |
|---|---|
| Racking Bench | Supports the bottles during racking |
| Racking Tube | Extracts wine from the sediment |
| Siphoning Tube | Transfers wine to the receiving container |
| Rubber Stopper or Clip | Secures the racking tube in the bottle |
| Receiving Container | Collects the racked wine |
Storing the Racked Wine
After racking, the wine should be stored in a cool, dark place to prevent spoilage and aging. The ideal temperature for storing wine is between 55 and 60°F (13-16°C), and the humidity should be around 70%. Wine should be stored away from direct sunlight, as UV rays can damage the wine.
Wine can be stored in a variety of containers, including glass bottles, stainless steel tanks, and oak barrels. Glass bottles are the most common type of container for storing wine, as they are relatively inexpensive and inert. Stainless steel tanks are also a good option for storing wine, as they are easy to clean and sanitize. Oak barrels are often used for aging wine, as they can impart a unique flavor and aroma to the wine.
The length of time that wine can be stored depends on the type of wine, the storage conditions, and the container in which it is stored. Red wines generally have a longer shelf life than white wines, and wines stored in oak barrels can age for many years. However, even the best-stored wines will eventually deteriorate, so it is important to consume them within a reasonable amount of time.
Factors to Consider When Storing Racked Wine
There are a number of factors to consider when storing racked wine, including:
| Factor | Considerations |
|---|---|
| Temperature | The ideal temperature for storing wine is between 55 and 60°F (13-16°C). |
| Humidity | The humidity should be around 70%. |
| Light | Wine should be stored away from direct sunlight. |

Monitoring and Maintenance
Monitoring
Regular monitoring of the wine during aging is crucial to ensure its stability and quality. This includes:
-
Temperature
Optimal storage temperature varies depending on the wine style. Monitor temperature regularly to prevent spoilage or premature aging.
-
Humidity
Proper humidity levels maintain cork integrity and prevent oxidation. Use a hygrometer to ensure humidity is between 60-80%.
-
Racking
Racking removes sediment from the wine and exposes it to oxygen. Frequency varies based on wine type, but generally 2-3 times per year is recommended.
Maintenance
Maintaining the aging environment and equipment is equally important:
-
Cellar Cleaning
Clean the cellar regularly to prevent contamination and mold growth.
-
Barrel Inspection
Inspect barrels for leaks or damage that could compromise wine quality.
-
Equipment Maintenance
Keep racking equipment clean and sanitized to avoid introducing bacteria into the wine.
Racking Protocol
Proper racking technique is essential to minimize wine loss and oxidation. Follow these guidelines:
| Step | Description |
|---|---|
| 1 | Siphon the wine from the barrel or tank into a clean vessel, leaving sediment behind. |
| 2 | Add a small amount of sulfite to prevent oxidation. |
| 3 | Transfer the wine back into a sanitized barrel or tank, leaving some headspace for oxygen. |
| 4 | Monitor the wine after racking for any signs of spoilage or instability. |
Troubleshooting Common Issues
9. Oxidation
Oxidation occurs when wine comes into contact with oxygen, causing it to lose its fresh, fruity flavors and develop a brown or amber color. To prevent oxidation, use the following techniques:
- Fill bottles to the top and top up any bottles that have lost liquid during fermentation.
- Use inert gas (such as nitrogen or argon) to fill the headspace in bottles.
- Store wine in a cool, dark place to minimize oxidation reactions.
10. Sediment
Sediment is a natural byproduct of fermentation and can accumulate at the bottom of wine bottles. While sediment is generally harmless, it can affect the taste and appearance of wine. To remove sediment, use the following techniques:
- Cold stabilization: Store wine at cold temperatures (near freezing) for several days to encourage sediment to fall out of suspension.
- Fining: Add a fining agent (such as bentonite or gelatin) to the wine, which will bind to the sediment and settle it out.
- Filtration: Pass the wine through a filter to remove sediment.
11. Other Issues
Other common issues that can occur during racking include:
| Issue | Cause | Solution |
|---|---|---|
| Stuck fermentation | Yeast are not actively fermenting the sugar in the wine. | Add more yeast, adjust the temperature, or check for other potential causes. |
| Malolactic fermentation | Unwanted bacteria convert the tart-tasting malic acid in wine into softer-tasting lactic acid. | Control temperature and use proper sanitation techniques to prevent this. |
| Spoilage | Bacteria or other microorganisms contaminate the wine, causing off-flavors or odors. | Sanitize all equipment and ensure that the wine is stored in a clean environment. |
Benefits of Racking Wine
Racking wine involves transferring wine from one container to another to remove sediment and improve its flavor and clarity. Here are the key benefits of racking wine:
1. Sediment Removal
During fermentation and aging, wine can accumulate sediment, consisting of dead yeast cells, grape skins, and other particles. Racking separates this sediment from the wine, resulting in a cleaner, clearer wine.
2. Oxidation Reduction
Exposure to oxygen can cause wine to oxidize, leading to undesirable flavors and aromas. Racking reduces the amount of oxygen in contact with the wine, preventing oxidation.
3. Flavor Enhancement
Sediment can impart bitter or astringent flavors to wine. Removing the sediment through racking allows the wine’s natural flavors to shine through, resulting in a more enjoyable drinking experience.
4. Wine Stability
Racking stabilizes wine by removing bacteria and unwanted microorganisms that can cause spoilage or premature bottle aging.
5. Clarity Improvement
Racking removes suspended particles, improving the wine’s clarity. This enhances the wine’s visual appeal and makes it more enjoyable to look at.
6. Yeast Removal
Racking can be used to remove excess yeast from the wine. This is particularly important after primary fermentation to prevent secondary fermentation in the bottle.
7. Blending Promotion
Racking facilitates blending different wines by allowing them to be mixed and adjusted before final bottling.
8. Tank and Barrel Management
Racking allows winemakers to manage fermentation tanks and barrels more efficiently by separating wine from solids, freeing up space.
9. Wine Filtration
Racking can be used to prepare wine for filtration by removing large particles that could clog filters.
10. Flavor Development
Racking can promote flavor development in young wines by exposing them to oxygen in a controlled manner during the first few months of aging. This process, known as micro-oxygenation, can enhance the wine’s complexity and roundness.
How to Rack Wine
Racking wine is the process of transferring it from one container to another, typically in order to remove sediment or unwanted particles. It can also be used to blend different wines together or to age wine in a different type of container. Racking is a relatively simple process, but it does require some care and attention to detail to avoid introducing oxygen or other contaminants into the wine.
To rack wine, you will need the following equipment:
- A clean, sanitized container for the wine
- A siphon or racking tube
- A bucket or other container for the sediment
- A funnel (optional)
Instructions:
- Sanitize all of your equipment before you begin.
- Place the clean container on a lower surface than the container of wine you are racking from.
- Insert the siphon or racking tube into the container of wine, and start the siphon by sucking on the end of the tube.
- Once the wine is flowing, adjust the flow rate so that it is slow and steady.
- As the wine flows into the clean container, keep an eye on the sediment at the bottom of the original container.
- When you see the sediment starting to come through the siphon, stop racking and discard the remaining wine in the original container.
- If desired, you can use a funnel to help prevent any sediment from getting into the clean container.
- Once all of the wine has been racked, top off the clean container with more wine or distilled water to fill any headspace.
- Store the racked wine in a cool, dark place.
