Notes

How Red Wine Is Made
The skins of the grape are responsible for the red colour that the wines have. That's why it's vital that the juice come into contact with grape skins throughout the process of the process of fermentation. The tannins also come from the skins of grapes.


Winemakers today have a wider range of options as well as techniques and methods than their ancient predecessors, but the object remains the same: take sweet grapes, and let yeast to convert them into tasty red wine!


Fermentation

The initial step of the fermentation process is to place crushed grapes into tanks that will be used for the primary fermentation. The process begins with the chemical process that transforms natural sugars that are present in grapes into alcohol ethanol. The winemaker's team is cautious in the initial phase to be very careful when handling grapes since it's where a large portion of the aromas and phenolic properties are developed.


Wines from red are fermented by leaving the skins still on. The tannins and flavors are then added into the wines. This is done through a myriad of ways. When it comes to light fruity reds cold maceration involves adding dry ice in the tank for the duration of 5 to 10 days. This technique increases the extraction of flavour and colour, and assists in lactic acid conversion of the wine. Hot maceration is a more traditional maceration method and can be carried out after the conclusion of fermentation for wine with a full body.


Once the initial fermentation is complete, the winemakers will sort out the mucky sediment from the wine that is clear by the process known as the racking. The mucky yeast sediment and grape pip and skins falls to the bottom of the barrel or tank. It is an indication that fermentation is nearly complete, and the wine will be prepared for the next stage.


Pressing

It's essential to make sure you pick these at the right time because the skins that are black provide the bulk of the red coloring. It's also among the most significant (and difficult) times for winemakers!


Pressing the juice is second step following the fermentation. The winemakers have to submerge the "cap" (floating wine skin) under the juice by hitting it with a punch or pumping it over at least once a day. This is done to get all the flavor and tannin out of the skins of grapes as they are able to.


When the winemakers have done the pressing process, they allow the final product settle for several days. This allows the wine to absorb a little oxygen and change some of those harsh tannins to more silky ones. This allows the wine to be bottled.


Prior to bottling, certain winemakers will add clarification agents to the wine - things like egg whites, casein and so on to ensure that the wine retains their clarity. The wine is also filtered to prevent bacteria from spoiling it. It is a thrilling process, winemakers make different kinds of wine. This is a tradition that is practiced for hundreds of thousands of years, and is which is the reason we get our current variety of wine we enjoy currently!


Malo-lactic Conversion

Malolactic fermentation is an organic process where bacteria turn sharp malic acid to a smoother lactic acid (the kind found within milk). The wine softens and becomes less acidic. The acid levels also drop and this is a good thing. Winemakers can control when this happens by inoculating the wine with a desirable strain of bacteria. Or they could prevent this from occurring by maintaining lower temperatures and by using higher levels of sulfur dioxide during the process of making wine.


After the grapes are crushed they must be squeezed to remove their juices from skins and seeds. This is done with the use of a winemaking device known as a press. The device looks like a horizontal cylinder equipped with an inflatable bladder. ufanax has the option of choosing the amount of pressure to be applied to grapes. This determines the color of the finished wine as well as the tannin content.


The grape skins are responsible in a significant portion of the flavor and colour qualities of red wine. They require a certain amount of period of time in contact with the skins to get rid of the tannins and colours. Maceration is the key to creating red wine. It is dependent on the winemaker. this can last anywhere to a few days in Beaujolais Nouveau to 18 months to make a premium Bordeaux red.



Ageing

Depending on the winemaker, once fermentation is complete, there are various decisions that must be taken. Certain wine regions are required by law to determine the maturity of a wine, while others will refuse to release the wine if they don't think it's ready. This is often true when it comes to California's expensive wines. A few producers choose to age their wines in bottles for several years prior to release of the wine, a process known as "aging."


As wine ages, its chemical makeup alters. Chemicals can mix or disintegrate in response to conditions. Each bottle is unique since it is unique due to its chemistry. Chemicals may dissolve, form new ones or combine in different ways depending on conditions.


Ageing wine allows it to fully develop Many wines, especially those that have a bitter acidity, or mouth-drying tannins, taste much better once they've aged.


Tannins, which are chemical compounds that are found in the skins and seeds of the grapes, bind together over time into long chains that soften their astringent qualities. They also drop out of suspension, and then fall off as sediment over time, making a wine feel smoother in the mouth.


The aging process can help wines develop secondary or tertiary aromas and flavors, such as dried or candied fruit, preserves or baked items, nuts the earth, or even flowers. Red wines are often stored in oak barrels, which assists in rounding the tannins and adds more body.
