The hard seltzer and flavored malt beverage (FMB) market continues to boom, driven by consumer demand for crisp, refreshing, and innovative ready-to-drink (RTD) options. Yet, crafting a high-quality alcohol base for these beverages poses unique challenges—especially when fermenting nutrient-poor sugar substrates. To solve these problems, we introduce HG 20 and SuperNutri 26—a scientifically optimized pairing for efficient, high-quality alcohol base production. Let's dive into how these innovations redefine hard seltzer production.
The Challenges of Hard Seltzer Fermentation
Fermenting sugar-based wort for hard seltzers or FMBs demands precision. Without natural nutrients (unlike malt-based brews), yeast struggles to thrive, leading to sluggish or stuck fermentations, off-flavors. Key hurdles include:
1. Yeast stress from high alcohol and sugar concentrations.
2. pH instability due to acidic byproducts.
3. Temperature sensitivity impacting flavor and speed.
4. Nutrient deficiencies stalling fermentation.
Our solution? A tailored yeast-nutrient partnership that conquers these challenges head-on.
HG 20: The Neutral, High-Tolerance Yeast
The yeast HG 20 is a neutral flavor yeast with high tolerance to stressful conditions and robust fermentation kinetics. Using HG 20, brewers can easily get a neutral alcohol base which can be flavored.
SuperNutri 26: The Ultimate Fermentation Nutrients
SuperNutri 26 is formulated well-balanced nutrients with nitrogen, vitamins, minerals, survival factors of yeast and pH buffer capacity to maintain protein synthesis of yeast and yeast health and achieve optimal fermentation performance, which is especially important for super high gravity fermentations to ferment up to 21% v/v alcohol in 5-7 days. Survival factors in SuperNutri 26 can maintain the structural integrity of yeast membranes and ensure a healthy and vigorous fermentation. HG 20 and SuperNutri 26 are a premium combination for hard seltzer and FMB drinks.
Proven Applications: Recipes for Success
Here are guides of hard seltzer fermentations:
Application 1:
SuperNutri 26: 0.8-0.9g/L
HG 20: 0.2g/L
Sugar concentration: 200-220g/L
Temperature: 25℃
Alcohol yields: 12-13 %v/v
Fermentation time: 10 days
Using 1.8g/L SuperNutri 26, alcohol yield can get to 12.3-13.5% in 5 days.
Application 2:
SuperNutri 26: 1.3-1.4g/L
HG 20: 0.2-0.3g/L
Sugar concentration: 240-260g/L
Temperature: 25℃
Alcohol yields: 14.5-15.5 %v/v
Fermentation time: 8-10 days
Using 2.25g/L SuperNutri 26, alcohol yield can get to 14.8-16.1% in 5-6 days.
Application 3:
SuperNutri 26: 2.7-2.8g/L
HG 20: 0.3-0.4g/L
Sugar concentration: 280-300g/L
Temperature: 25℃
Alcohol yields: 17.2-17.85 %v/v
Fermentation time: 6-8 days
Using 3.6g/L SuperNutri 26, alcohol yield can get to 17.4-18.3% in 5 days.
Techniques for Successful Super High Gravity Fermentation
High gravity fermentation is a challenge and requires more techniques to overcome. HG 20 is a high alcohol tolerance and robust yeast with effective fermentation capability to absorb sugar. SuperNutri 26 provides proper and necessary nutrients for yeast growth and fermentation.
SuperNutri 26: 6.4g/L
HG 20: 1.6g/L
Sugar concentration: 350g/L
Temperature: 25℃
Alcohol yields: 21 %v/v
Fermentation time: 6 days
