S. cerevisiae • cerevisiae

• Isolated in 1991 at the Swiss Federal Research Station in Wädenswil, Switzerland.
• Its low heat generation during fermentation helps winemakers minimize the potential for temperature spikes and possible H₂S problems.
• Produces higher levels of glycerol and succinic acid, especially when fermented between 15-20°C(59-68°F), which helps add complexity to the mid-palate.
• In white wines, Lalvin W15^TM helps retain bright fruit characters while optimizing mouthfeel and balance. It also performs well with both Pinot Noir and cooler climate Syrah.
