Water: Essential Not Only to Life, But Also to Great Beer
Water is perhaps the most overlooked ingredient when homebrewers start out and certainly should not be. After all, more than 95% of beer’s composition is, you guessed it, water. It must be viewed in the same way as any other core ingredients in beer — those being malt, hops, yeast, and of course, water.
In fact, water is the first ingredient that you should consider when making beer, whether you’re brewing with a prepared ingredient kit or designing your own recipe.
When a brewer chooses the malt for a particular recipe it seems like something one could spend days or even weeks contemplating. With that in mind, it’s important to understand that water merits just as much thought. It serves as the base for your brew, and will have a big impact on how the final product turns out, regardless of whether you did everything else right and used other choice ingredients.
So, what are the main types of water readily available to you for brewing? Chances are you can get your hands on distilled, purified drinking, tap and maybe even rainwater if you have a barrel for a home garden or other purposes. Let’s go through the different types and how they relate to brewing.
