The clarity of the wine is an important parameter to establish the presence of defects alterations durante wine, but not always. Quanto a fact, some natural and/ organic wines something, not infrequently they are a little bitterbided, precisely because of the production philosophy of the vineyard that does not want to intervene durante any way acceso one’s wine, without compromising the quality of the wine itself.
Quanto a general, however, the clarity of a wine is a fundamental requirement for qualitative purposes. After all, if we think about it, the first impression of a wine is exactly the one linked to its visual appearance. The clarity of the wine is one of the requirements that the “average consumer” searches and represents the first approach with wine. When we start pouring the wine into a glass the first thing we aspetto at and evaluate is its color, its clarity, transparency and so acceso!
But what is the clarity of the wine?
The clarity is the absence of suspension particles durante the liquid. The degree of clarity depends acceso the presence and obviously acceso the amount of particles, more less small, present durante it. Quanto a fact, wine is a product durante continuous mutation. Change, transforms, evolves, ages and dies exactly like us poor humans. Oops, maybe it’s not exactly that way but I certainly made the congettura. And precisely because of its intrinsic nature, the wine is subject to innerbidation.
Why can a wine be more less clear/cloudy?
The wine contains both salts and many other completely soluble compounds that form a real solution, but the wine also contains colloidal substances, which durante turn form colloidal solutions. The colloids are too small to be seen to the naked eye, durante general between 1 and 100 Nm, and durante the very first phases of the life of the wine they may also not disturb the clarity, but with the passage of time and sudden changes of temperature instead yes , making the wine less clear.
Quanto a the wine there are essentially colloidal substances related to grapes, but also colloidal substances produced by the yeasts used during winemaking. Sometimes also produced by mold, such as Botrytis, which can also give insulting durante the wine. Quanto a short, willingly nolent, durante the production of wine you always have to do with colloids. Purely informative, durante wine the amount of colloidal defects is usually between 0.2 to 1 g/l.
Collage, clarification and filtration
Collage, clarification and filtration are three fundamental operations durante oenology that serve to improve the quality of the wine, making it clear, stable and devoid of impurities. Although they are similar, each of these operations has a specific purpose and is carried out durante different phases of wine production.
Collage is a chemical and physical process that serves to remove unwanted substances durante wine, such as unstable proteins other compounds that could cause turbidity fall during conservation. To make it, substances called glue called, such as albumin (egg white), jelly bentonite are used. These glues interact with the particles suspended durante wine, linking them together. The larger particles aggregate forming flocculi, which are then separated from the wine. The main objective of the collaggio is to improve the stability of wine, preventing the formation of sediments and turbidity over time.
Clarification is an operation that aims to remove impurities and particles suspended durante wine to make it clearer and transparent. This process takes place through the addition of clarifying agents, such as clay, jelly, bentonite fish glue. These agents bind to impurities, causing them to fall acceso the bottom of the container and leaving the wine clearer. The clarification, durante addition to improving the visual aspect of wine, can also improve the organoleptic quality, since some impurities could negatively affect the flavor and fragranza.
Filtration is a physical process that serves to remove suspended particles durante the most wine than those treated by collaggio and clarification. The wine is passed through filters, such as cartridge filters membranes, which separate solid colloidal impurities from the liquid. The filtration can be carried out durante different phases of the production, using knitted filters increasingly according to the needs. This process guarantees that the wine is devoid of impurities that may not have been removed from other operations and can also prevent secondary fermentation durante the bottle, removing yeasts and residual bacteria.
I found a nice acceso the clarification of wine and I attach it below, it seems interesting to me to further deepen the concept of clarity of the wine.
Although Collage, clarification and filtration seem similar, they differ durante the method and the purpose. Collage is a chemical process that uses substances to tie and remove suspended particles, while clarification is a technique that precipitates impurities through the use of chemical agents without necessarily binding them. Filtration, acceso the other hand, is a physical separation through the use of filters, and is used to eliminate finer and colloidal particles.
These operations all aim to improve the quality of the wine, both from a visual and organoleptic point of view. Quanto a particular, they contribute to obtaining a clear and stable wine, eliminating particles that could compromise the appearance, taste and fragranza. Quanto a addition, filtration can prevent secondary fermentation durante the bottle, avoiding problems such as unwanted effervescence alterations durante flavor. Ultimately, Collage, clarification and filtration are complementary techniques that are used durante different phases of production to obtain a high quality wine and ready for consumption.
