WLP618 White Labs NA All Day Ale Yeast

White Lab's WLP618 NA All Day is a unique non-conventional yeast strain, Saccharomycodes ludwigii, specifically chosen for its low ethyl acetate production. It enables brewers to craft high-quality non-alcoholic and low-alcohol beers while preserving aroma and body.

This maltose-negative strain does not ferment maltose or complex sugars, only fermenting glucose, sucrose, and fructose. As a result, it delivers a significantly lower alcohol content while maintaining balance and flavor, making it an excellent choice for NA beer production.

WLP618 NA All Day Yeast Characteristics

• Attenuation: Up to 20%
• Flocculation: Medium
• Alcohol Tolerance: Low (2 - 5%)
• Optimum Fermentation Temp: 68 - 75°F (20 - 24°C)
• STA1: Negative

Key Considerations for Brewing Non-Alcoholic Beer

• Keep Wort Fermentability Low: Use a smaller grain bill to decrease original gravity to 5-7° Plato and mash at a high temperature (above 162°F / 72°C) to reduce fermentable sugars.
• pH Adjustment: Adjust the wort pH to below 4.6 using phosphoric or lactic acid for microbial stability.
• Stabilization: Use a 0.45-micron sterile filter and a microbial stabilization method to ensure shelf stability.
• Enhancing Flavor: Post-fermentation additions of non-sugar flavorings, water profile adjustments, or the inclusion of unmalted grains can help improve body and mouthfeel.
