Features gentle bitterness and herbal/floral aromas from hops
Refreshing mouthfeel, moderate sweetness, with no alcoholic sting
Can be crafted into various flavor styles (from pale to dark, light to robust)
1.2 Target Audience:
Pregnant and breastfeeding women
Drivers and professionals who need to stay alert
Athletes and fitness enthusiasts
Individuals with alcohol intolerance or sensitivity
Consumers seeking low-calorie alternatives
1.3 Core Advantages:
Zero alcohol content, suitable for all-day consumption
Rich in B vitamins, amino acids, and minerals
Low in calories (approximately 30-50% fewer calories compared to beer)
Serves as an innovative base for cocktail mixing
Part 2 – Brewing Ingredients: The Cornerstone of Quality
2.1 Selected Barley Malt:
Base Malt: Pale malt (provides fermentable sugars and foundational flavor)
Specialty Malt: Caramel malt, chocolate malt, roasted malt (adds color and unique flavors)
Quality Requirements: Plump grains, uniform germination, free from mold and impurities
2.2 Hop Selection:
Aroma Hops: Such as Cascade, Citra (added late to preserve aroma)
Bittering Hops: Such as Magnum, Nugget (added early during boiling to extract bitterness)
Form: Pelletized or extract, facilitating filtration and flavor control
2.3 Water Treatment System:
Reverse osmosis or deionized water treatment equipment
Water quality adjustment system (regulates pH and mineral content)
Key Parameters: Calcium ion concentration: 50-150 ppm, Chloride ions: <100 ppm
2.4 Auxiliary Ingredients:
Natural Sweeteners: Honey, maple syrup, fruit concentrates (optional)
Natural Flavorings: Citrus peel, spices, herbs
Acidity Regulators: Food-grade lactic acid, citric acid
Part 3 – Core Processes: From Grains to Sweet Wort
3.1 Mashing Process: Releasing the Soul of Malt
1). Process Flow:
Malt Crushing: Use a roller mill to moderately crush the malt while keeping the husks intact.
Mashing-in: Mix the crushed malt with warm water (45-50°C) in a specific ratio.
Step Mashing:
Protein Rest: 50-55°C, maintain for 20-30 minutes.
Mashing Stage: 63-68°C, maintain for 60-90 minutes (β-amylase activity).
Mash-Out: 78°C, maintain for 10 minutes.
2). Key Equipment:
Mash tun (with stirring and heating systems).
Temperature control system (accuracy ±0.5°C).
pH monitoring and adjustment devices.
3.2 Lautering and Spent Grain Separation
1). Process Points:
First Filtration: Pump the mash into the lauter tun, allowing it to settle and form a natural filter bed.
Recirculation Clarification: Return the initially turbid wort to the lauter tun until it runs clear.
Sparging: Rinse the spent grains with 78°C hot water to extract remaining sugars.
2). Equipment Configuration:
Lauter tun (with a false bottom and rotating spray arm).
Wort holding tank (capacity determined by production scale and brewing frequency).
Spent grain conveying and handling system (capacity determined by production scale and brewing frequency).
3.3 Boiling and Hop Addition
1). Boiling Process:
Time: 60-90 minutes (shorter than beer to reduce Maillard reactions).
Intensity: Gentle boil, evaporation rate controlled at 5-8%.
Hop Addition Timing:
Bittering Hops: Added at the beginning or within the first 30 minutes of boiling.
Aroma Hops: Added in the last 15 minutes of boiling or after boiling.
2). Equipment Requirements:
Boil kettle (with external or internal heating systems).
Hop addition port and metering device (optional).
Evaporation and condensate recovery system (optional).
3.4 Whirlpooling and Cooling
1). Whirlpooling Process:
Hot wort is introduced tangentially into the whirlpool tank, creating a vortex.
Hot trub and hop residues settle to form a cone-shaped pile.
Settling time: 20-40 minutes.
Rapid Cooling:
Use a plate heat exchanger to cool the wort to 4-10°C.
Cooling medium: Ice water or glycol solution.
Nitrogen purging (optional, to prevent oxidation).
2). Key Equipment:
Whirlpool tank (with conical bottom design).
Plate heat exchanger.
Chilled water preparation system.
Part 4 – Blending and Post-Processing: Crafting Unique Flavors
4.1 Flavor Blending System
This is a key stage that distinguishes unfermented malt beverages from beer, achieving product differentiation through precise blending:
1). Blending Methods:
Base Wort Standardization: Adjust sugar content (Brix), color, and pH.
Flavor Addition:
Natural fruit juices or purees
Herbal extracts
Spice infusions
Functional ingredients (e.g., vitamins, electrolytes)
Sweetness Balancing: Use natural sweeteners to adjust final sweetness.
2). Blending Equipment (determined by budget and production capacity):
In-line blending system (with static mixer)
Multi-component dosing system
In-line Brix and pH monitors
4.2 Pasteurization: Ensuring Safety and Shelf Life
1). Process Parameters:
Temperature: 72-75°C
Time: 15-30 seconds (High-Temperature Short-Time pasteurization)
Cooling: Immediate cooling to below 20°C
2). Equipment Configuration:
Tubular or plate pasteurizer
Precise temperature control system
Integrated design combining cooling and pasteurization sections
Part 5 – Filling and Packaging: Sealing in Freshness
5.1 Filling Production Line
