Information about Winemaking and Yeast Nutrients


So many things should be considered about the winemaking process and this is especially true for people who are having their first experience with making their own wine. You have to understand all the necessary things that you need to know about the process of fermentation and all that is required to ensure that your wine ferments properly. One of the most important things that you need is nitrogen and unless you have it, your yeast won’t be able to reproduce at the high rate that is necessary to quicken the process. Yeast also helps in making the wine age a whole lot quicker, it is thus essential to ensure you find the necessary stimulant to ensure that the yeast carries out its job.

What this entails is finding a good supply of nitrogen and the simplest way to do this is to buy yeast nutrients. What this supplement does is that it puts nitrogen into the yeast. It is usually best used along with wines which have been made from grapes or berries. The ingredient which makes the yeast nutrient able to add this much nitrogen is phosphate. Such nutrients also tend to absorb the fatty acids which are in the wine in order to slow down the process of fermentation.

In some cases it is usually best to make use of a yeast energizer as this also helps in putting the needed nitrogen into the yeast but in a different manner. This is done by placing much more nutrients in the yeast followed by just the phosphate which is used up by the yeast nutrient. It also makes use of a different form of phosphate which is known as di-ammonium phosphate including proteins such as Riboflavin, Thiamin and vitamins. It can also be used for various types of winemaking. You should think in terms of wines which have been created from other fruits, vegetables and herbs and as such would need a yeast energizer. They do not have the needed nutrients present in grapes and berry wines so they need some extra boost in order to ferment properly.

Yeast energizer also tends to be useful when the wines which are being made require high alcohol content. When you talk of high alcohol content, it usually refers to anything which is more than 14 percent. It serves to encourage the second phase of fermentation which may sometimes stop for no reason at all. The yeast energizer is what initiates the process. It is what will be used if you need to restart a fermentation process which has come to a complete stop. Mixing with some fresh yeast or a minor amount of wine together with the yeast will start the fermentation process after about 12 hours.

Lipids are also found in yeast and they are another nutrient. When the yeast cells divide, the lipid tends to lessen and make it harder for the yeast to reproduce more of itself. What this means is that the yeast production slows down quickly. By adding a lipid supplement the yeast will grow much faster than expected.

Guide to Making your Own Wine Recipe


After you have had an opportunity to experiment with making your own wine you may naturally decide that it is time to begin creating your own wine recipes. This is quite common. There are a number of advantages to creating your own recipes. For example, you can avoid the hassle of having to look around for a recipe every time you want to make a batch of wine with the fruit that you have available. In addition, you gain the ability to experiment and possible produce a really original, great batch of wine.

Like any recipe; however, wine recipes must have a specific format and certain ingredients in order to be successful. Let us examine it from the point of view of baking a cake. There are certainly hundreds, if not thousands, of different cake recipes. Line them all up and they are decidedly different. In order for a cake to be a cake; however, the recipe must have several basic ingredients. For example, you are usually going to need some type of flour, sweetener and something to help the cake rise. This is a basic formula that forms the basis of cake recipes. While you may not think of it, it is really a matter of science.

A wine recipe is no different. There are certain ingredients that must be included in any wine recipe in order for the end result to work. These ingredients are: produce, sugars, water, nutrients, acid and yeast.

First, you will need to start with something to make the wine. Most wines are made from grapes but you can use practically any fruit or vegetable matter; even herbs if you wish. You can also use concentrated juices as well. In addition, you will need sugars in order to start and support fermentation. If you do not add sugar to your wine recipe, fermentation will not take place and without that, your wine will not have any alcohol. In most cases, the fruit that you select for your wine will produce the necessary amount of sugar but that is not the case with all produce. For example, if you are making dandelion wine then you will need to provide sugar because the produce will not be able to produce any of its own. You may also find that you need to occasionally add some sugar to support the sugar that is provided.

Water is essential in order to dilute flavors that may be too strong. Common examples of wines which may need to be diluted with water include blackberries, elderberries and gooseberries.

Nutrients are also essential. Keep in mind when creating your wine recipe that the yeast which you will add to your wine is a living organism. As a result, it needs nutrients to thrive and support a healthy fermentation process. Usually, you will need to add some nutrients to your wine. Common examples of nutrients include Yeast Energizer and Yeast Nutrient.

Do not overlook the importance of acid in your wine. While you certainly do not want to have too much acid in your wine, it does play an important role in the fermentation process. If the acid level in your wine is too low then the fermentation will not be as successful as it should be. Acid also assists in the stability of your wine. Also, without sufficient acid, your wine may very well develop bacteria and molds that could ruin your wine. Tannic acid and Acid Blend can be used to help add necessary acid to any wine recipe.

Of course, no wine recipe can be complete without yeast. Yeast is what basically does all of the work of converting the produce you have chosen into wine. Without yeast, there can be no wine. You will need to make sure that you have yeast that is specifically designed for winemaking. Do not make the mistake of thinking that you can use the yeast you have in the kitchen for bread making. Even yeast designed for brewing beer will not work for making wine.

The Importance of Racking


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.

How to Start your Own Wine Journal


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.
