Water in Brewing

Water in brewing is often overlooked in discussions about beer. Water is in fact the unsung hero behind every pint. Comprising up to 90% of a beer’s composition, water is the canvas upon which brewers paint their masterpiece. Its influence extends far beyond mere hydration, shaping the flavor, aroma, mouthfeel, and overall quality of the brew. Let us dive into the profound impact water has on one of the world’s favorite beverages.

No two waters are alike, and this holds true for brewing. Different regions possess distinct water profiles, each lending its own character to the beers crafted within its borders. Take Wyoming, for instance, where the soft water serves as a boon for brewers. Soft water, with its low mineral content, is ideal for styles like pale ales and lagers.


Mineral content, including sulfate, chloride, calcium, and magnesium ions, holds the key to unlocking the beer’s aromatic bouquet. A balanced mineral profile is the secret ingredient for a velvety mouthfeel that complements the beer’s hop character. Overemphasizing certain minerals can upset this delicate balance, overpowering the beer’s harmony. Different beer styles require varying mineral profiles to accentuate their unique characteristics.

Soft water has low mineral content. This allows the delicate flavors of pale ales and lagers to shine through in the final brew. Soft water highlights the refined malt and hop characteristics of Pilsner lagers.

Meanwhile, sulfate and chloride influence bitterness perception, with the right balance preserving and highlighting hop aromas. A balanced sulfate-to-chloride ratio enhances hop character in American IPAs. Sulfate levels can amplify hop aroma in styles like IPAs. Similarly, a balanced mineral profile with an emphasis on chloride complements the malt sweetness in Vienna lagers, exemplifying the symbiotic relationship between water and beer.

Moreover, minerals like chlorine and chloramine, if present in tap water, can sabotage the brew with off-flavors reminiscent of medicine or plastic.


The pH level of water is not merely a number. It is a conductor orchestrating the symphony of flavors in beer. Water pH impacts aroma perception. Higher pH levels (basic) enhance malt sweetness, while lower pH levels (acidic) accentuate hop bitterness. Thus, water in brewing plays a crucial role in balancing the beer’s taste profile.

Water in brewing consistency

Clarity and appearance, crucial for visual appreciation, are also affected by water chemistry, impacting beer’s overall sensory experience. Hazy beers are often equated with low quality beers. Ensuring clarity by starting with a solid understanding of the water profile is key to obtaining a crisp clear beer. Irregularities in the starting water profile can lead to diminishing consumer perception of beer quality.

So, Consistency is king in brewing, and water quality is no exception. Maintaining consistent water quality ensures uniformity in aroma, flavor, and the visual characteristics of the beer from batch to batch.

In conclusion, each beer style demands a specific water profile to reach its full potential. From Pilsners to IPAs, water quality is key. In the intricate dance of brewing, water takes center stage, guiding the flavors, aromas, and textures of every brew. Understanding its nuances and harnessing its power is the mark of a true brew master. So, the next time you raise a glass, take a moment to toast the unsung hero behind every sip: water in brewing, the foundation of great beer. Cheers!
