WLP618 White Labs NA All Day Ale Yeast

White Lab’s WLP618 NA All Day is a specialized brewing yeast,Saccharomycodes ludwigii, developed for non-alcoholic and low-alcohol beer production. With low ethyl acetate output, this strain ensures a clean fermentation profile.

As a maltose-negative yeast, WLP618 does not ferment complex sugars, focusing only on glucose, sucrose, and fructose. This makes it an ideal choice for achieving low-alcohol content while preserving body, mouthfeel, and aroma. Perfect for brewers designing high-quality NA beer styles.

WLP618 NA All Day Yeast Characteristics

• Attenuation: Up to 20%
• Flocculation: Medium
• Alcohol Tolerance: Low (2 – 5%)
• Optimum Fermentation Temp: 68 – 75F (20 – 24C)
• 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 162F / 72C) 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.
