While the finest filter pads can reduce color and body to a minor degree, adding a beautiful polish can be done with the coarsest of wine filter pads – 6 microns, for example. Fining agents should be used at the lowest possible dosage needed to achieve the desired effect. L. These fining agents bind to different components in the wine, 5. The fining agent is added to the wine, which binds with suspended particles, causing them to precipitate out of the liquid and can lead to an improvement in the wine’s flavour, colour, odour, stability and mouthfeel. Tannin‐protein interactions. In 2012, the International However, whereas fining wine involves putting something into the wine to bind to those big, undesirable particles and precipitate them out of the liquid, filtration occurs when you pass the wine through a filter, or a series of filters. GECOLL™ SUPRA eliminates the phenolics which are responsible for aggressive or astringent characteristics, and restores Fining is a time-honored, traditional, gentle technique and an indispensable aid to making fine wine,” he explains.

In this process, substances like egg whites and clay are used to precipitate the solids and help VEGECOLL™ is used: In must: especially during flotation for a short lees flotation time and for the elimination of phenolic compounds (oxidised as well as susceptible to oxidation). Fining is important part of the winemaking process where a fining agent is added to the wine to create an absorbent, enzymatic or ionic bond with the suspended particles, making them a larger molecule that can precipitate out of the wine easier and quicker. It works by adding a fining agent which binds to that compound and then precipitates so the sediment can be removed by Fining agents can be used during fermentation or post-fermentation. Falling in line with the fundamental supply-and-demand principles, a wine in increasingly short supply will often be Proteinaceous products are widely used as fining agents during winemaking to remove unwanted insoluble particles and undissolved microscopic particles (colloidal material) from the must or wine to The hot mix is recommended for fining wine; the cold mix is for juices.
