The Process of Manufacturing Wine

Nicholas Tan asked:

Wine, which is a drink we all know and love, is produced from fruits such as grapes and berries by drying and then fermenting them.  Once the fruits ferment, the sugar within the fruit will turn into alcohol.  The wine will display a different color, taste, and aroma depending on the type of fruit that it was made from. 

Wine is divided into three main categories – fortified, sparkling, and table.  Wine is known as fortified when a bit of brandy is added into it to enrich the alcohol.  Wine is deemed as sparkling when it has the right level of C02.  Table wine, the third category, is wine in it’s natural form – which is different from any other type of wine.

Normally, grapes are the preferred ingredients for making wine.  They contain an equal amount of acid and sugar, which can’t be found in any other type of fruit.  When drying the grapes, a high amount of heat is needed.  To use grapes with wine though, you need to know the exact harvest season.  If you don’t pick the grapes during the right time, your wine will suffer due to the level of increases in sugar and a lack of acidic extent.

During the beginning stages of wine making, the grapes or other fruit is crushed by a large cylindrical container that will deflate the juicy parts of the fruit into large bags that are attached to the machine.  Next, the juicy part of the fruit is fermented through the use of heat.  During this part of the process, present yeast will help to convert the sugar into alcohol.  Once the sugars start to break down into alcohol, the wine will get a buttery flavor.

Next, is the settling.  Settling involves the yeast cells or any other type of material flowing near the top of the wine.  Once it is at the top, it is then filtered with all sediments being gathered on the filter.  Aging is next, which is where the wine is tightly packed away in special contains that won’t allow any contact with air for months – sometimes even years.  Once the wine has been aged, it is transferred into smaller bottlers then shipped out and sold.

When the wine is bottled, it is done in a way that makes it easy to distinguish the several types of wine.  Colored bottles are preferred, as they will greatly reduce the risk of oxidation, damage, and several other possible risks.  The bottles are also labeled according to their manufacturer and brand as well, which makes it easy for you to select the wine you are interested in.

Once you have bought a bottle fo wine, you should always make sure you store it in the right place.  The most appropriate places to store wine is the basement, underground cellars, or anywhere else that is damp and cool.  No matter where you store your wine at, you should always make sure that temperature stays around 55 degrees F. 

Never store the wine in an area where the temperature fluctuates, as it can harm the wine.  A humidity level of around 60% is also important, in order to keep the cork moist.  If the temperature is too low, it can also harm the wine.  When you buy your wine, you should always make sure that you store it in the right location.  Wine that is properly stored and taken care of can be truly amazing once you drink it – making it more than worth the time and effort.

Steps and Processes Which Go Into the Making of Wines

Muna wa Wanjiru asked:

There are a few steps and processes which go into the making of wines and the final evolution that appears magically on our tables.

When to Pick the Grapes

This is a crucial step in the process of wine making and as such should be taken seriously. Picking the grapes at the wrong time could yield different results to the ones you were expecting. The decision to pick the grapes depends to a very great extent on the weather conditions. For instance, if it’s very sunny then the grapes should be picked in the cooler night time environment.

Then again, there’s also the determining factor of the grape variety itself. This combined with the style of wine you want, i.e. dry or sweet, will also be a factor in making the right decision. And then you also have the acidity levels of the grape to check, the sugar levels, the Ph levels and so on and so forth.

Picking the Grapes

Having made the decision to pick the grapes you can now move on to the actual process of picking the grapes. Depending on the size of the vineyard the picking operation varies.

Generally though, you’ll find that containers are placed in easy-to-get-to places, and that most times the grapes will be handpicked. The grapes will then be rushed to the crushing platform where they will go through another check before they will be weighed in and then processed.

It is important that the grapes arrive at the crush platform while they are still fresh. So if the vineyard is a big one, then the grape picking operation will either be carried out mechanically, or with a staggering number of people at hand to ensure the grapes are picked and delivered within about eight hours. The time will naturally vary from vineyard to vineyard, but the urgency to get them off as soon as possible doesn’t.

De-Stemming the Grapes

After all the visual checks have been performed, and the grapes have been weighed in and so forth, they will next be dumped into a de-stemming machine. Here, the stems of the grapes will be removed to avoid mixing in with the grapes, as they are rather astringent and have a bitter flavor to them.

The Grape Skin

Since the skin of the grape is where the greater flavors and aromas are stored, most grapes are given a 24 hour skin contact time, where they are allowed to interact with the skin.

Pressing the Grapes

Depending upon the type of wine to be made the grapes are then either skinned, or are left intact with the skin still on. This is done when the grapes are sent through the wine press. In this machine the grape is sent through the machine to extract the juice, and the skin and seeds are separated from the grape.

Cold settling

The grape juice or “must” is then cold-settled and racked fresh from the grape press. This is to separate any stray bits of skin which might have traveled with the juice. This is mainly done for white wine grapes as the skin is not part of the fermentation process.

Fermentation

The grape juice is then sent to be fermented. The fermenting process happens as a result of the yeast that is added to the juice. The vats or barrels are then sealed and fermentation begins. The yeast will transform the grape juice into wine over a period of time. This varies with the grape variety, the wine variety intended, and other small little details.

Since the yeast breaks down the sugars in the grape juice into carbon dioxide and alcohol, the bubbles that form as a result of the carbon dioxide are released through a small vent. This is where the champagne making process changes, in that it goes through a second fermentation process where the carbon dioxide bubbles are trapped in and sealed into the wine, thereby creating the bubbly wine.

Racking

Once the fermentation of the wine is complete, the racking process begins. This is to clear out the yeast that has collected in the bottom of the fermentation barrel. The wine is pumped out leaving the yeast behind, and this process may take place more than once before the wine can be deemed clear.

Fining

This process involves clearing out excess tannins or proteins which might disturb the proper balance of the wine.

Cold stabilization

This process makes the acids that are naturally present in the wines, stable.

Filtering

Not all wines require filtering but some do, and this is accomplished by using the necessary filtering equipment.

Bottling

This is the last step in wine making, and often many years might have passed between the decision to pick the grapes, to the actual part of bottling the wines ready to ship out.

This is the process though, which brings us closer to the wines, as this is the time when we, the consumer, are allowed access to the wines.
