The process of making wine is one that many find to be fascinating. There are several steps in the process and each has to be done with the utmost care in order to ensure the quality of the wine.
The first step is choosing the needed grapes. After they have been picked, they won’t go on to ripen as many other fruits would. This means that timing is everything when picking grapes to make wine with. The wines with the highest level of acidity use slightly less ripe grapes. The opposite happens when picking grapes to make sweet wine with. These grapes have ripened more so than the ones used to create acidic wine.
When a winery receives its grapes the first thing they do is process them. Grapes are sorted and then squeezed out, but not washed because this would have a negative effect on the final product. Sorting grapes is done when creating a wine such as Cabernet Sauvignon.
Making Pinot Noir and other similar wines require the use of thinly skinned grapes. The harvesting of these grapes routinely includes their stems in the fermentation process, in order to add necessities such as phenolics and tannin.
This is in contrast to grapes with thicker skin, which usually have their stems removed during the winemaking process. The reason for this is that the removal of the stems lowers the level of bitterness that the tannic and phenolics cause.
The process of making white wine is somewhat different. White grapes are gently squeezed with a wine press in order to get the juice out of them. After the squeezing process is complete all that remains in the grapes is pomace, which is often used in the food and even cosmetics.
In some cases, making white wine involves a short period of soaking the seeds and skin of the grapes. As a result, white wine has more of a rich consistency than it otherwise would.
The next step in the process for red and white wines is for it to go into fermentation tanks. Yeast is then added as well. The yeast helps complete the process of fermentation. When the process has been completed the wine is cured, bottled and shipped out to stores and restaurants.
