When it comes to brewing hard seltzer, the water profile is an important factor that can significantly impact the final product. The right water composition can enhance the flavors and contribute to a clean and refreshing taste. In this regard, I strongly recommend using distilled or reverse osmosis (RO) water for brewing hard seltzer.
Distilled or RO water is ideal because it is stripped of impurities and minerals that might interfere with the desired flavor profile of the seltzer. By starting with a clean and neutral base, you have more control over the brewing process and can create a consistent and high-quality product.
However, it's important to note that completely stripped water might lack some essential minerals that can contribute to the mouthfeel and overall balance of the hard seltzer. To address this, I suggest adding a mineral water pack consisting of specific minerals in appropriate amounts.
One common mineral water pack recipe for brewing hard seltzer includes 1.25 grams of magnesium sulfate (Epsom Salt), 1.25 grams of magnesium chloride, and 1.5 grams of sodium bicarbonate (Baking Soda). These minerals can help create a well-rounded flavor profile and provide a pleasant mouthfeel to the seltzer.
Magnesium sulfate, also known as Epsom Salt, contributes to the smoothness and body of the seltzer. It can enhance the mouthfeel and provide a slight mineral character. On the other hand, magnesium chloride adds a subtle sweetness and can help balance the acidity in the seltzer. It contributes to the overall flavor complexity and can help round out any harsh edges.
Sodium bicarbonate, commonly known as Baking Soda, acts as a pH buffer and can help maintain a balanced acidity level in the seltzer. It can also contribute to a more rounded and smoother taste, reducing any sharp or bitter notes that might arise during the brewing process.
It's essential to measure and add these minerals accurately to achieve the desired water profile. Keep in mind that different brands of mineral water packs may have slightly different compositions, so it's always a good idea to refer to the instructions provided by the manufacturer.
In my personal experience as a brewer and sommelier, using distilled or RO water as a base and adding the recommended mineral water pack has resulted in excellent hard seltzer batches. The flavors were clean, crisp, and well-balanced, providing a refreshing drinking experience.
For brewing hard seltzer, I highly recommend using distilled or RO water as a base. To ensure a well-rounded flavor profile, consider adding a mineral water pack consisting of magnesium sulfate, magnesium chloride, and sodium bicarbonate. These minerals can contribute to the mouthfeel, balance the acidity, and enhance the overall taste of the seltzer.
