The process of racking involves siphoning the wine away from the sediment. Sediment is primarily comprised of inactive or dead yeast cells. While yeast is beneficial to the must in the beginning, over time it becomes multiplied many times over. As each new generation of yeast is produced, older generations die off. Most of what you will see at the bottom of your fermentation container is dead yeast cells.

As the fermentation nears the end of the cycle, there should be a significant amount of active yeast cells which are beginning to wind down because they are running out of fuel; or sugar. After the sugars have become consumed the active yeast will begin to starve and feed on itself. An enzyme will be produced that will break down the inactive yeast cells. The purpose of this is to release the nutrients in the dead yeast cells that can be used by the yeast cells that are still active. This process is called autolysis. Over a period of time, an otherwise perfectly good batch of wine may be ruined as a result of this process.

Racking is also important because it can assist in the clarification of the wine. If wine is not racked, the end result will be wine that may be clear on top; however, the bottom will be somewhat thick and hazy.

The racking process is not terribly difficult. In fact, it is quite simple. A siphon is necessary for racking. The key; however, is to make sure that you siphon off the wine without stirring up any of the sediment. It should be noted that while food grade hosing can be used many winemakers do prefer to use what is known as a racking tube in order to rack their wine. This is because, if you are not careful; using a hose to rack the wine can cause the sediment to become stirred up and it may also move around. A racking tube fits on the end of the hose and serves as a type of wand that gives you control over where in the container you draw the wine.

In the old days, wine was racked by manually sucking on the end of the hose; however, today there have been numerous advancements made in winemaking equipment. One of those advancements is an automatic siphon that works with a pump in order to start the siphoning action.

Keep in mind that during the first two to three rackings, it is not essential to remove all of the sediment. You should try to siphon as much of the wine liquid as possible; however, even if you do bring up a small amount of the sediment this will be fine. It is during the final racking that it becomes imperative that you make sure that all of the sediment is left behind with none following through into the wine.

After the fermentation process has been completed, it you still need to rack the wine (such as when storing wine long-term in bulk) it may be necessary to add Campden Tablets to the wine. The purpose of this is to ensure that any air that may have entered the wine during the racking process is driven out. Campden Tablets will also help to minimize oxidation. Keep in mind that this is not a problem when racking wine while the fermentation process is ongoing as the CO2 that is produced during fermentation will naturally eliminate any air that may have been introduced.

Many years ago homemakers made a practice of keeping kitchen journals. A lot of information went into those journals, including successfully adapted recipes and the likes and dislikes of guests who were frequently invited to dinner. These kitchen journals made the process of running a kitchen far more efficient.

If you are going to make wine at home, it is a good idea to consider keeping your own wine journal or notebook. One of the keys of producing good wine is being consistent. A wine journal will allow you to do that as well as track your progress as you develop advanced skills. In the beginning your notes may not seem like much; however, over time this information can become extremely valuable. You may think that you will be able to rely on your memory; however, this can be quite dangerous if you want to consistently develop good wines. After a few batches, there is a very good chance that you will forget exactly which details worked best and which you would like to avoid.

The type of information that should be recorded in your journal includes any information that would have an impact on the final outcome. Of course, it is not necessary to list trivial information that will not really have any impact; however, you will definitely want to include information such as the brand of yeast you used and temperature recordings for your wine must.

Other information that should be included in your winemaking journal includes:

• How much fruit you used
• The type and amount of sugar you used
• Amount and type of yeast
• Amount and type of nutrients

It is also important to keep specific information about dates as well. You should make a note of when the yeast is put into the must as well as the dates of when rackings are performed. In addition, any time you add ingredients, you should make a note of this as well. Also, be sure to note when you bottle the wine. You may also want to include any information about how the wine looks or even how it tastes when you do a sample taste test.

Hydrometer readings are also critical to the development of any batch of wine so it is a good idea to record those readings and the dates they were taken. Over time, you will be able to gain a lot of insight from the hydrometer readings that you record. Keep in mind that you should take hydrometer readings when the fermentation process is first begun as well as during any rackings. Readings should also be taken at the end of the fermentation process as well. In the event you add any fruit or sugar to the must during the fermentation process, it is also a good idea to take a hydrometer reading before the addition is made as well as after.

Practically anything that you feel comfortable with can be used for your winemaking journal. If you want to keep it simple, consider using something like a spiral composition notebook. The one problem with using this method is that you may find it difficult to keep your notes consistent. To combat this problem you might want to develop your own wine log. This can be easily done using any word processing program on your computer and then printed out and placed in a 3-ring binder. When every page is identical you will have prompts to help you remember the type of information that should be recorded. This type of binder will hold up better over time as well. In addition, depending on the width of the binder, you can easily add more pages as you need without worrying about running out of space.

You may also find it helpful to add other reference information that will be right at your fingertips. For example, you might wish to print off conversion charts and place those in your binders so that you can access the information quickly while working with your wine.

Racking is one of the most essential parts to making stellar wine. Generally, you will need to rack the wine at least two times and in some cases you may need to rack it as many as four times. Making sure that you rack in a timely fashion will ensure the wine is properly clarified as well as prevent off flavors.

If you are not familiar with racking, it is important to understand that racking does not refer to bottling the wine. This is a misinterpretation. Basically, racking involves siphoning the wine from one container to another. The purpose behind this is making sure that all of the sediment is left behind.

The first racking typically occurs about five days into the fermentation process. In some cases, you may wait one to two days; however, the first racking should always occur by day 7. This is because by this time you will need to place an air lock on the container in order to protect the wine must due to the fact that the fermentation has slowed down. Outside contaminant could easily influence the wine, so you will need to provide necessary protection using an air lock.

You will also usually find that at this point in the fermentation process at least 70% of the sediment will have already begun to appear. If you rack between days five and seven, this will be a good opportunity to get rid of most of the sediment. It will be some time before the remainder of the sediment appears. Racking at this point is also important because it presents you with a chance to remove pulp from the must. This is imperative if you used fresh fruit instead of concentrate. If you leave pulp in the must for any longer, you may find that your wine has a harsh taste.

The second racking should take place when the fermentation process has been completed. The amount of time necessary for this to occur may vary. In some cases it may take only a few days following the first racking while in other cases it could be several weeks following the first racking. The amount of time depends on how quickly the fermentation progresses. After you have completed the second racking, do take care to re-apply the air lock as the must will still need some time in order to clear.

The third racking should take place after the wine has become completely clear. This will give you the chance to get rid of any remaining sediment. Under specific circumstances, you may find that it is necessary to perform subsequent rackings. For example, when you are aging a heavy red wine in bulk, you may find it necessary to rack the wine approximately every three months or so. This is because some sediment may still occur over the course of the wine being stored in bulk for a long period of time.

In the event you decide to use clarifiers or finings you may also need to perform subsequent rackings. In this case, you would need to rack the wine once before the wine is treated and then once again after treatment. It should be noted that it is entirely possible to rack your wine too many times. This should be avoided as it can cause the wine to become over-oxidized.
