PEF Benefits for White Wine
More freshness. More aroma. More precision.
Elea PEF supports controlled extraction and efficient fermentation while helping protect the delicate compounds that define white wine.
Optimise white wine from grape to cellar
White winemaking is all about balance: extracting what adds value while preserving freshness, aroma and varietal character.
Elea’s Pulsed Electric Field technology gently opens grape cells during processing, helping wineries improve extraction and fermentation performance without adding unnecessary process intensity.
The benefits
MORE AROMA & FRESHNESS
Support the preservation and release of delicate aromatic compounds.
CLEANER PROFILES
Support clearer aromatic expression with fewer unwanted fermentative compounds.
IMPROVED BODY & BALANCE
Enhanced extraction can contribute to greater mouthfeel, roundness and balance.
FASTER FERMENTATION
Improve fermentation efficiency and free up tank capacity during harvest.
PEF technology is transforming white wine production, reducing fermentation time by an impressive 8 days. By applying Pulsed Electric Fields to destemmed and crushed grapes, this innovative process enhances the release of sugars, enzymes, and essential compounds, allowing yeast to work more efficiently. The result is faster fermentation while preserving the fresh, delicate flavours that define quality white wines.

The increase in glutathione is likely due to improved extraction, as PEF treatment breaks down cellular structures, enhancing its release into the must before fermentation. Glutathione plays a crucial role in protecting the wine from oxidation and preserving its freshness and aromatic qualities during the shelf life or ageing process.
In addition, PEF can double the concentration of volatile thiols—compounds responsible for many of the tropical and citrus aromas in white wine—further enhancing its aromatic intensity and complexity.
In Chardonnay, PEF treatment creates a more layered flavour profile, with greater body, a vibrant character, and longer persistence on the palate. The result is a fresher, more refined wine with its delicate aromas beautifully preserved.
