Sodium Hydrogen Carbonate, NaHCO3, 50 g

In beer brewing, NaHCO₃ (sodium bicarbonate), also known as baking soda or sodium hydrogen carbonate, is used primarily to adjust the pH of brewing water and manage the overall water profile. It plays a crucial role in influencing the chemistry of the mash and the final flavor of the beer.

1. pH Adjustment:

• Sodium bicarbonate increases the alkalinity of the brewing water, helping to raise the pH. This is particularly useful when brewing with dark, roasted malts, which tend to lower the mash pH due to their acidity.
• Maintaining the proper mash pH (typically 5.2–5.6) is essential for efficient enzymatic activity and proper starch conversion.

2. Water Chemistry Balancing:

• Sodium (Na⁺) and bicarbonate (HCO₃⁻) ions introduced by NaHCO₃ affect the water profile, contributing to the overall flavor balance of the beer.
• Sodium at low concentrations can enhance sweetness and improve the malt character, while bicarbonate helps neutralize acids in dark malts.

3. For Specific Beer Styles:

• Beers such as stouts and porters, which use a significant amount of acidic dark malts, often benefit from the addition of sodium bicarbonate to prevent the mash pH from dropping too low.
• It can help emulate water profiles from brewing regions historically associated with certain beer styles.

Usage Guidelines:

• Measurement: Begin by measuring the pH level of your brewing water and mash. Use a reliable pH meter or high-quality pH strips for accuracy. Knowing the initial pH helps you determine how much adjustment is needed.
• Dosage: Add small amounts of sodium bicarbonate (NaHCO₃) gradually, stirring thoroughly after each addition. Recheck the pH after every dose until you achieve the desired level, typically between 5.2 and 5.6 for the mash.
• Dissolution: Ensure that the NaHCO₃ is fully dissolved in the water to avoid clumping and promote even distribution throughout the mash.
• Monitoring: Continue monitoring the pH during the mashing process. Make further adjustments if necessary to maintain a stable and optimal pH level.
