Clarify, protect, and stabilize your wine from the start
In modern winemaking, preventing browning and preserving the freshness of wine is no longer an option, it is a requirement. Proveget Lumière is an eco-friendly solution that acts selectively on oxidizable and oxidized phenolic compounds, protecting the varietal character from the must.
Thanks to its innovative formula based on vegetable protein, bentonite, inactive yeast, and yeast protein extract, it drastically reduces the negative effects of oxidation without compromising the quality or sensory profile of the wine.

Frequently asked
Proveget Lumière acts selectively on oxidized and oxidizable polyphenols without interfering with the aromatic compounds or the varietal expression of the wine. Unlike PVPP, which under certain conditions can induce slight bitter or astringent notes—especially in sensitive matrices or at high doses—Proveget Lumière does not cause sensory imbalances. Its natural and balanced composition preserves the freshness, brightness, and typical characteristics of the wine, offering clean clarification that respects the organoleptic profile, even reducing bitter and astringent notes.
Although Proveget Lumière is not specifically formulated as a deproteinizing agent, its natural bentonite content may contribute to the flocculation and partial removal of unstable proteins present in the must. However, this action is complementary and does not replace a specific protein stabilization treatment. Therefore, depending on the degree of protein instability in the wine, it may be necessary to apply a suitable deproteinizing agent afterwards.
Although Proveget Lumière is not specifically designed to eliminate the polyphenols responsible for pinking, its action on oxidation precursors—especially hydroxycinnamic acids and catechins—as well as its ability to intercept reactive quinones, contributes to significantly reducing the risk of this phenomenon occurring in sensitive varieties.
The optimal time for application is at 1/3 of alcoholic fermentation. This promotes early action on polyphenols, limiting their involvement in browning reactions, secondary oxidation, and the formation of unstable colloidal complexes.
Thanks to the synergy between its mineral fraction (bentonite) and its protein components, Proveget Lumière generates compact, easy-to-separate sediments, which improves racking efficiency, reduces wine losses, and contributes to a cleaner and more predictable operation.
Yes. All the ingredients in Proveget Lumière are natural and compatible with European organic regulations, as well as being suitable for wines certified under the NOP (National Organic Program).
Yes. Proveget Lumière is free from allergens that must be declared, such as milk, eggs, nuts, and gluten. It does not contain animal proteins or derivatives that could cause adverse oenological reactions or labeling restrictions.
Yes. The formulation of Proveget Lumière is composed exclusively of ingredients of plant or microbial origin, with no animal traces, making it completely suitable for vegan wines and ideal for wineries seeking certification in this segment.
