As we all know, fermentation is one of the critical stages of winemaking. Without fermentation, it is impossible to create wine. In some cases; however, you may find that you have problems with the fermentation process. Usually, these problems will take the form of either fermentation that just does not occur at all or else is too slow.
One of the reasons that this may occur is that the temperature was either too cold or too hot. Remember that yeast cells are live and in order to become activated they require a temperature that is between 70 and 85 degrees Fahrenheit. Ideally, you should aim for around 72 degrees; however, if you drop below 70 or go above 75 degrees, you will have problems. When the temperature is too cool, the fermentation will likely not occur at all. When the temperature is too warm; however, the yeast can become damaged and will also perform poorly.
This is why it is critical to ensure that you have a stable temperature in the room where you ferment your wine. If the temperature in the room fluctuates, you will generally have problems. Basements tend to make the best places for fermentation; provided the area does not become too cool during the winter. In that case, you can provide a small heat source. Making sure that your fermentation containers are not placed directly on the floor may also help. You can also use a thermometer to monitor the fermentation. A floating thermometer can be placed right in the wine and you can lift it out when you want to check the temperature.
Improperly starting the yeast can also result in problems with fermentation. This is also commonly due to problems with temperatures. Most yeast packets require the yeast to be rehydrated, or moistened, with some warm water prior to use. Ideally, this should not cause any problems. That is, unless the water temperature was too warm. Most yeast packets call for the temperature to be somewhere between 95 and 105 degrees. If the water exceeds these temperature limits even just a small bit, the yeast is likely to be destroyed. As a result, it is unable to support the fermentation process.
As a result, it is important to make sure that you actually verify the temperature of the water before you add the yeast. In addition, it is important to make sure that you do not leave the yeast in the water for too long. Generally, you will need to leave the yeast in the water for about fifteen minutes. If you walk off and forget about the yeast and leave it in the water for even a few minutes longer, you will also run the risk of destroying the yeast cells. Therefore, it is important to keep an eye on the clock and make sure that the yeast does not remain in the water for any longer than 15 minutes at the most.
Adding too much sugar can also cause problems in the fermentation process. Remember that while it is necessary for yeast to have sugar in order to produce alcohol, you can add in too much sugar. When the sugar level is too high, it may begin to have a detrimental effect on the ability of the yeast to produce alcohol. This is why it is critical to verify the amount of sugar that is already present in a batch from the fruit itself before you add in any additional fruit. Remember that the fruit itself will have its own amount of sugar. This level can vary from one fruit to another, making it even more important to verify the sugar content level. A hydrometer can be used for this purpose. If you have not previously used a hydrometer it is a good idea to invest in one and become acquainted with it. A quality hydrometer can help you to avoid many of the problems that might otherwise ruin a good batch of wine.

Here are some basic tips for bottling and aging your wine at home. First, a cool environment for storing wines would be ideal because it reduces the effects that oxidation will have on the wine. This is the main reason why you need cool temperatures to store your wines, and why many experts in how to make wine from the home recommend that you store your bottled wine completely out of direct sunlight. You may have noticed that even commercial wineries often store bottled wine in dark cellars or basements. This lessens the incidences of oxygen production in the bottled wine that could alter the taste, often for the worst.
Follow this important rule but don’t get too worried about simple changes in the temperatures where your wine is being stored. A few degrees higher or lower in the temperature scale will have minute effects on your bottled wine that would not be discernible. But, when learning how to make wine from home, it is important to prepare a storage area in advance so that you are not wasting time fretting around for a cool place to store your wine.
It should be quite obvious to you that temperature fluctuations can really be harmful to your bottled wine. This means that a room with a 65 degrees Fahrenheit stable temperature is always preferable to a room whose temperatures are indeed cooler than 65 degrees but will fluctuate from 65 down to 50 then back up again to 65.
Insane temperature fluctuations like this are a challenge for the home wine maker because often it is difficult to find storage at home where cooler temperatures can be controlled to a stable range. Therefore, it is important when undertaking how to make homemade wine that will be good to taste, to prepare the storage area in advance.
Rapid changes in temperature will change the flavors quite significantly. The aromas will wear down, the wine will taste bland, and maybe your bottled wine will lose that character you were seeking for that bottled wine variant. Though your bottled wine may be able to put up with one night of temperature fluctuations, when the temperature flux occurs over a longer period, the stored bottled wine will eventually wear down under these kind of stresses.
When the temperature rises, the wine itself will expand and so in turn, will the wine bottle itself. You will not notice this change because the wine bottle will not balloon out of phase. But natural physics tells us they both will indeed react this way to higher temperatures. When temperature falls, the wine and bottle will then contract. The wine does not expand and contract at the same rate as the bottle though they are subjected to the same temperature in the room. The wine itself tends to expand and contract more than the bottle it is in.

No matter what you tipple is; white, red, pink or sparkling, storing your wine correctly is essential. Simply putting your favourite bottle above the fridge and forgetting about it for a year could drastically alter the taste, then, when you come to enjoy it at that special occasion, it might not be as favourable as you hoped.
Despite wines being a perishable commodity, properly caring for and storing your wine can actually improve its’ aroma, flavour, texture and complexity over time.
Step 1: How long are you storing your wine for?
The first decision to make is how long you are planning to store your wine for. Generally short term storage means 3 to 6 months and should be your cheaper, less cherished wines, where as long term can mean decades and should be reserved for your quality, precious wines.
Step 2: Correct storage conditions
Whether it’s short or long term storage the same rules apply, firstly and most crucially the bottles should be laid horizontally instead of upright, this ensures the cork remains moist, to stop it drying out.
It is essential to keep the wines in a vibration free environment so they can not move about, therefore on top of electrical appliances or a place subject to external forces (i.e. from a subway) should be avoided.
Wine can be greatly affected by its surrounding temperature; the ideal temperature is roughly 55 degrees Fahrenheit (12°C). Bottles should be kept out of drafts and any temperature change should be very gradual.
Additionally light can negatively impact on a wine, which is why some wine bottles are made of coloured glass. Wine must be kept out of direct sun light, since too much light can react with proteins in wine, forming a haze and bad aromas to pollute its’ flavour.
For long term storage, the correct atmospheric conditions are required. Humidity has to be very high, approximately 70% or more, in order to stop the cork drying out and to reduce the chance of wine evaporating. Also when storing long term, consider the wines surroundings, ensure there are no other foods or liquids that could be absorbed into the wine itself. Substances with strong aromas for example fuel or vinegar must be kept elsewhere!
Step 3: Enjoy
When the time comes to pop the cork and savour all your hard work, drink responsibly but do try to finish bottles within a few days of opening, since as soon as the wine is exposed to air it starts mixing with oxygen. This is known as oxidation, which also alters the essence of the wine.
Correct wine storage is fundamental for any serious wine lover, enthusiast or even hobbyist. The most effective storage is in a wine cellar, since numerous bottles can be kept conveniently out of sight yet in the perfect conditions.
Cheers!

Storage is absolutely key to the success of any wine collection. Anyone who enjoys collecting fine wines will want to look for the best available wine storage options. There are many different ways to properly store wine, but regardless of which wine storage solution is ultimately chosen it will critical to keep the storage conditions constant.
A constant temperature of constant 50-60 degrees Fahrenheit must be maintained within any wine storage space. The wine storage should be as far away from the main area of the house as possible, and there must also be plenty of ventilation in the selected area. The wine collection must not suffer too much vibration and any light sources should be kept to a minimum. Absolutely no sunlight should be permitted to reach the wine storage area.
Of course a wine cellar can be used for wine storage or a special cooler can be built. Wine racks are, predictably, a necessary part of any wine storage solution. Wine racks can be made of metal or wood, and the wine storage chosen is primarily a matter of personal taste. While both kinds of rack building material are attractive to look at, the metal racks tend to be more flamboyant and stylish while the wood racks are often considered more classic and traditional in style.
It may be preferable to choose racks in order to have them match the rest the chosen wine storage solution. These final choices will be influenced to a certain degree by whether or not the wine cellar is intended to be shown off to friends and colleagues. If it is, then the wine storage solutions will need to appear more coordinated.
Either way it’s not a bad idea to look into wine racks and other wine storage options that will all look good together. This helps to create a wine storage area that looks like it belongs to a professional wine collector. It’s not difficult to accomplish, but it can cost a bit of cash.
Temporary wine storage options are, customarily, a little simpler. Immediately prior to serving a wine it will probably need to be chilled, depending of course on what kind of wine it is. In order to store wine for chilling, look into cool wine storage solutions. Available in many department stores or wine stores, wine coolers are easy to find. Even the Internet is an excellent resource for finding these types of wine storage options.
