Originally wood had the straightforward function in relation to wine production and that was to provide a leakproof container for storage and transportation, ie, the barrel! In time wine winemakers discovered that storage in wood had other advantages such as assisting in the clarification and stabilising the wine but also adding complexity to the wine in terms of flavour to white wines and structure and longevity to the reds. For people who also want to know something about New Zealand wine, you can check online with IT services Auckland for wine NZ.
Wine can be stored in small barrels, known as “barriques”, through to large casks. Barriques will impart stronger flavours due to the larger surface area in contact with the wine. Alternative, cheaper methods have been used such as adding oak chippings to the wine during fermentation, either loose or in a large “teabag” suspended in the wine. The winemaker can also insert wooden barrel staves into the tank to achieve a similar result.
Before 2006, the practice of using oak chips not allowed in the European Union.The main types of oak used were French oak and American oak. French oak is very tightly grained and imparts a more subtle influence on the wine. Some of the most important oak forests in France are the forests of Nevers, Allier, Troncais, Limousin and Vosges each lends a distinct characteristic. American oak has a more open structure and is used for the more full bodied reds such as Australian shiraz and the red wines of Rioja. The oak from Minnesota or Wisconsin is the best for aging wine.A couple of years ago I visited a winery in Rioja that was experimenting with Eastern European oak and indeed barrels that were made from up to three different oak types.
The influence of oak on the wine is dependent on the time spent in the barrel or in contact with staves etc. Whether it stretches over a few months or over a year. Some wines are also fermented in oak barrels. This practice is usually reserved for the higher quality white wines as it gives a rich, creamy texture and helps to integrate the oak flavours but its use in red wines is on the increase.
Even in heavily oaked wines the effect of the oak will lessen over time and the hard tannins soften. The effect produced is always in the control of the winemaker. The final result can be produced from blending wines from different vineyards that have been aged in different types of oak for longer or shorter periods. In fact part of the blend may not have seen any oak ageing at all to preserve its natural fruit flavours.

If you have been thinking about buying one or two Wine Coolers then more than likely you have been looking at all the wine cooler reviews that are online. When you are thinking about getting a new wine cooler you really need to take the size of the actual unit into account before your purchase.
There are some Wine Coolers that you can get that have dual compartments and these are fantastic for keeping both red and white wines at different temperatures. So why should you keep your wine in a wine cooler or wine refrigerator – lets have a look at a few reasons.
Wine needs to be stored at a temperature of about 14 degrees Celsius if you keep it in a place that is too hot or too cold it can have a detrimental effect on your wine. Too hot and your wine will stew or cook and if it is too cold your wine can actually freeze.
When wine gets cold it can freeze and contract – not literally freeze – this is just a term. And if your wine is kept in a place that is too hot the wine can expand and it will speed up the reactions taking place inside the bottle and also push the cork out a bit and let air inside. If the cork becomes too dry it will move around in the bottle (as it shrinks).
Many WINE Coolers will come with a humidity tray and also dual compartments. If you keep these things that we have looked ta in mind when you are looking at wine coolers online you should be able to find a cooler that suits your needs. Looking after your wine is important if you want to be able to enjoy it. Make sure that you take good care of your wine and you will be able to age it properly. Enjoy storing your wine and enjoy drinking it too. Cheers – Here’s to wine !!!

Benefits Of Using Beer Yeast
You should read this!
Beer yeast can be biologically described as a microorganism that belongs to the plant kingdom fungi. It is used to ferment compounds such as carbohydrates and sugars. The carbohydrates are converted into alcohol and organic acids that may contain carbon dioxide. The fermentation process may produce alcoholic or non-alcoholic beverages depending on components used and temperatures they are subjected to.
They are cylindrical in shape at the top and conical at the bottom to allow yeasts to flow downwards and settle at the bottom. There are two major types of yeasts used in commercial production of alcohol. Both types are fully spread throughout the beer during fermentation process. They also both settle at the bottom of the containers used when fermentation is complete.
Breakdown of components can take place at different temperatures. When involving warm temperatures, the process takes place in open places. When sugars and microorganisms are subjected to low temperatures, they are stored for a month or longer. During this period the sulphur compounds that had developed dissipate.
There are two major types of yeasts used in the manufacture of alcoholic beverages. Ale an example of top cropping yeasts causes foam to settle at the top of the beverage during the fermentation process. Even though bottom cropping yeasts can be used to produce ale type alcohols, they are commercially used to produce lager type alcohols. They ferment well at low temperatures.
Yeasts are used in bottle fermentation where its feasible suspension provides natural carbonation. Where there are inadequate sugars left to ferment, extra amounts may be added to ensure continuity of the process. Fermentation of sugar containing plant compounds produces ethanol and other substances such as water. By-products depend on the chemical structure of the plant compound.
Beer yeast is rich in most vitamin B and contains necessary minerals for the body. It ferments slowly but produces few unnecessary flavours. It is well known to tolerate high alcohol content and hence is used to make highly concentrated alcoholic spirits. Read this: brewing beer
