Alcohol Wine

Wine which is an alcoholic beverage is made from fermented grape juice.  Grapes can ferment without any addition of sugar, enzymes, acids or any other nutrients. Wine is basically produced by fermenting the crushed grapes by making use various types of yeast. The yeast converts it into alcohol by consuming the sugars found in the grapes. Depending on the type of wine to be produced, different types of yeast and grapes are used.
The word ’wine’ originates from the Proto-Germanic ‘winam,’ which is an early borrowing of the Latin vinum.

History


According to archaeological evidence  the earliest known production of wine which was made by fermenting grapes, took place in sites in Iran and Georgia, around as early as 6000 BC. A report by archaeologists in 2003 indicates that grapes were possibly used with rice to obtain mixed fermented beverages in China in the early 7000 BC.
The oldest evidence of production of wine in Europe is dated back to 4500 BC and comes from the archaeological sites of Greece. The evidence of the world’s earliest crushed grapes were also found at the same sites. References to wine are also abundantly found in Homer (9th century B.C.), Alkman (7th century B.C.)  and others. During medieval times in Europe, the Roman Catholic Church was very much a staunch supporter of wine since it was a necessity for the celebration of Mass. Monks in France made wine for many years, storing it underground in caves for it to age.

Grape varieties


Wine is made from one or more varieties of the European species named Vitis vinifera, such as Chardonnay, Cabernet Sauvignon, Pinot Noir , Gamay and Merlot. A Varietal is formed when one of these varieties is used as the predominant grape (usually defined by the law as a minimum of 75% to 85%), as opposed to a blended wine. Blended wines are not considered inferior to varietal wines, some of the most expensive wines of the world, from the regions of Bordeaux and the Rhone Valley, are very much blended from the different grape varieties of the same vintage.

Tasting

Wine tasting is defined as a sensory examination and evaluation of the wine. Its sweetness is determined by the amount of sugar in it after its fermentation, which is relative to the acidity present in the wine. For e.g. dry wine has only a small amount of residual sugar. Inexperienced wine tasters often mistake the taste of ripe fruit for sweetness when, many a times the wine in question is dry. The aroma of the wine comes from the volatile compounds in the wine that are released into the air. The process of Vaporization of these compounds in wine can be sped up by swirling the wine glass or serving it at room temperature. Many people prefer the red wines like Chinon and Beaujolais which are already aromatic, chilled.

Uses


A wide range of European and Mediterranean-style cuisines, from the simple and traditional to the most sophisticated and complex are enhanced by wine which is a very popular and important beverage.
As a flavor agent, Wine is important in cuisine not just for its value as a beverage,but primarily in stocks and braising, since its acidity gives balance to rich savoury or sweet dishes. White, red, and sparkling wines are the very popular. They are known as light wines since they contain only 10–15% alcohol-content by volume. Apéritif as well as dessert wines have 14–20% alcohol. They are often fortified to make them rich and more sweet.

Health Effects



Though excessive alcohol intake has adverse health setbacks, epidemiological studies have repeatedly demonstrated that moderate intake of alcohol or wine is statistically followed by a decrease in death because of cardiovascular events such as heart failure. A boom in red wine consumption started in the 1990s in the United States by the TV flick 60 Minutes. Additional news articles on the French Paradox recorded these facts.The French paradox refers to the slightly lower (in comparision) incidence of coronary heart disease in France inspite of high levels of fat(saturated) in the conventional French diet. Some epidemiologists feel that this difference is because of the higher intake of wines by the French, though the scientific evidence supporting this theory is limited. The moderate wine consumer is more likely to take to exercise more, to be more health conscious, and to be of a higher socioeconomic and eeducational class, evidence that the relationship between moderate wine consumption and health may have a realtion with the confounding factors.
Resveratrol, a chemical in red wine, has been shown to have cardioprotective as well as chemoprotective effects in animal research studies.

Packaging


Majority of wines are sold in glass bottles. They are sealed using corks. More than 50% of production comes from Portugal. An growing number of wine producers are also using alternative closures like screwcaps as well as synthetic plastic "corks". In excess to being less expensive, these alternative closures also prevent cork taint, though they have been blamed for some problems like excessive reduction.

Storage


If they are above-ground, wine cellars, or wine rooms are places designed specially for the aging and storage of wine. In an active wine cellar, humidity and temperature are taken care of by a climate control system. Passive wine cellars aren't climate-controlled, and therefore must be carefully situated. Wine is a perishable food product; when exposed to light, heat, vibration or fluctuations in temperature as well as humidity, all types of wine (red, white, sparkling, and fortified) can spoil. Wines can maintain their quality and in some cases improve in flavour, aroma, and complexity as they age when stored properly. Some wine experts are of the opinion that the optimal temperature for aging of wine is 55 °F (13 °C).[72], others say 59 °F (15 °C)

Alcohol In Wine


Alcohol in wine is as crucial an element in the final product as grape itself. It not only effect how you feel after drinking it but also affects the taste, structure, and texture of the wine. 

Alcoholic strength is in the ethanol, the main product of fermentation, in wine. It can measured in percentage as compared to proof, the manner alcohol is measured in hard liquor.  In the U.S., if the wine is labeled as a “Table Wine”, it must contain less than 14% alcohol by volume. The law also allows a 1.5% extra exception.  If a label reads 12.5% alcohol by volume, it can in practice be as high as 14% or as low as 11%.  In the U.S., if a label simply reads “Table Wine” then the alcohol presence is between 11% and 14%.  In Europe, the range is between 8.5% and 14%.

These numbers were decided because most grapes after fermentation are present somewhere between 8% in alcohol by volume on the low end, as opposed to 14% on the high end.  But, that was quite long ago.  Today wines can come in quite higher, especially in hot weather places like Australia. Also, with new viticulture techniques, as well as greater controls in the wine-making process, it is not surprising to see wine exceeding 15% in alcohol.  There are some Syrahs and Zinfandels the heavy hitter grapes, that can go up to 16.5% in alcohol by volume, which is quite a lot. Quite Obviously, the “Table Wine” print is not on their label!

The alcohol content approximately is:
Table wine:  8 – 14%
Sparkling  wine:  8 – 12%
Fortified wine:  17 – 22%

Fortified wine is simply wine that has been strengthened by addition of alcohol. Some Wines that fall into this category are dessert wines, Port or Sherry.  Alcohol has a enormous effect on how a wine feels as well as tastes in the mouth.  In table wine, i.e. wine which inherits its alcohol content from the fermentation of grapes alone, alcohol tends to add a sweetness.

Ice Wine

Ice Wine

This is a dessert wine that can only be made when it is very cold out. Ice wine is made from those gapes which are deliberately allowed to stay on vines longer than normal time.l... into the time when it begins to snow.. This wine is very sweet so it would go well with maybe some cheese. You don't want something too sweet to eat with this wine. This wine will have fresh, clean flavors of citrus, the tropical fruit lychee, minerals, and floral.

Ice-wine is an extraordinary gift from the extreme cold climate of Canada. The most spectacular thing about this grape is that each grape produces joss a luxurious and rich smooth drop of ice-wine...
Ice wine though not invented in Canada, but was perfected there. The whole process of harvesting is done by hand as soon as the temperature drops below -19 to -13 degree Celsius. The water portion inside the grape freezes inside naturally in form of crystals and remains inside while pressing, but the tiny amount of concentrated juice expressed out.
The ice wine is very expensive as compared to the other wines. This is due to the fact that when the grape is frozen; dried and thawed the grape produces one fifth of a normal unfrozen grape would produce. Thus where a grape would produce one bottle of wine, the frozen grape would produce just a glass full of it.

The wine thus obtained is intensely sweet and the acidity gives in a dry finish. The wine has an aroma of lychee nuts and taste of tropical fruits like plums, mango and peach. Once swallowed it leaves a refreshing sensation to one.
The most predominant grapes used for this wine are sauvignon Blanc, Riesling, cabernet franc etc…
A quick look in the history or say the origin of this wine shows us that. During the exceptionally cold winter in 1794, the Franconia wine producers due to the necessity for money used the frozen grapes for making wine, and there it was the first glass of ice-wine. They were quite surprised by the sweet and high concentration of sugar. But it was only 1800 are that it was first commercially produced.

The ice-wine producing grapes need nice long warm summer season and extreme winter, which is provided in the Niagra region of Canada. Also Quebec is fine producer of this wine.
A bottle of ice-wine once opened is best used up within 3-5days, provided that after opening it is re-corked and refrigerated well. This because of its high sugar content.
It should be served in a long stemware with a fairly large open bowl, which is said to amplify its aroma and the flavor intensifies.
Best served chilled but not icy cold with a fresh fruit palate.

Port Wine

Port Wine


This is a fortified wine. This is usually a dessert wine that goes great with cheese, dark chocolates and nuts
Port wine is a fortified wine from Douro valley in Portugal; it is a classical way of ending a meal .this wine is partially fermented after adding about 15-20% of brandy or alcohol. Depending upon how n when the fermentation is stopped the wine gets its taste from sweet to semi sweet or dry. It holds a spicy taste low in tannins and acidity yet very smooth.

Before all the natural sugar is converted into alcohol, high grade alcohol is added to it, this stops the fermentation and brings out a deep sweet color and flavor to the wine along with its existing sweetness.                                                                                           This method helps the wine soak up fruity flavor and gives it grater longevity. After this they are allowed to rest in oak casks.

Now we come to different varieties of this wine:

Vintage port: they are very grapy due to storing them in oak barrels up to 2yrs .these have to further be held in bottles for up to 20years for that great vintage taste. These years provide it the smoothness.

Ruby port: they are younger (avg 2yrs) and soak the brandy and yet retain their rich red ruby color .with a fruity aroma they leave a lingering freshness in ones mouth.
Tawny port: they are aged for 3-4 years in wooden barrels. They have more of nutty taste than fruity as they tend to lose their fruity flavor and develop an amber color. It is also called as “ports of the vintage”.
Wood port: they are finest of all and solely allowed to age in barrel and not in bottles.
Tinto barroco, Malyasia preta, Tinta roriz, Mourisco etc are some of the red varietals that are used for making port wines.

Rose or Blush Wine

Rose or Blush Wine

A Rose' wine is a low alcohol type of wine. Flavors will range from the tart, acidic wines with little or no oak, to big fruity wines. Typically these wines are served very chilled and really go with a lot of different foods. This is because of their low alcohol content.

Blush wine
Blush wine is a pinkish wine that is made from the red grapes whose skins are removed before the fermentation process begins. also known as rosé wine, its color varies from light pink to orange tinges until purple at times depending upon the wine making techniques and the variety of grapes used.
The name “blush wine” is  mainly used in north America and has replaced the term rosé almost completely and now its considered almost passé.

The term “blush” is fairly used to encompass not only the wines which are rose pink in color but a whole wide range of shades from pink to pale orange and sometimes to light purple red.
These wines range from sweet to dry to light and medium bodied wine.
History
In 1970;s there came a time when the availability of white wine fell extremely short as opposed to its demand .so many wine makers tried experimenting by making wines from red varieties with minimal skin contacts during wine making process thus trying to produces light colored wines. once it so happened in 1975 that while making white zinfandel the process suffered from stuck fermentation wherein the yeast dies before the process completes. when winemaker Bob Trinchero tasted this wine after a few days he preferred selling this blush wine, which he named as rose wine.

Synonyms
• Blush wine
• Rose
• Rose wine
In Australia the term “blush” was used mainly to cash in on the newly discovered some link between the genetic code of zinfandel and primitive style..
The blush wine is characterized by sweet taste with residual sugar of 2.5%.
The grapes are firstly crushed and for a short time the skins are allowed to remain in contact with the crushed juice. Then later the skin is discarded by pressing the grapes. this is done because the skin contains strong tannin flavorings. If the skin is left in contact for a long time then the color of the wine grows more intense.
these wines should be served chilled not icy .they are a great with a variety of light flavored platter.
