Ferments cleanly at low temperatures

In white wines, Lalvin W15™ helps retain bright fruit characters while optimizing mouthfeel and balance. Performs well in Pinot noir and cooler climate Syrah.

Produces glycerol and succinic acid, especially when fermented between 15–20°C (59–68°F), adding complexity to the mid-palate.

Low heat generation during fermentation helps winemakers minimize the potential for temperature spikes and possible H2S problems.

Isolated in 1991 at the Swiss Federal Research Station in Wädenswil, Switzerland.
