Why can water be the hidden hero in your home brewery?
In the world of homemade beer, many concentrate on malt, hops and yeast. However, water quality can make the big difference between a normal beer and a product that leaves everyone wanting more. While large -scale breweros teachers spend time adjusting their water profiles, at home perhaps we underestimate the importance of liquid purity with which we mix malt and more.
What about extract beers? Is water chemistry equally relevant?
The process of creating liquid or dry malt extracts is essentially an industrial version of the mashing. It starts from malted barley, which is subjected to precise warming to turn starches into fermentable sugars, like an artisanal brewer. The difference is that manufacturers do most of the work for you, concentrating and drying the must by controlled heating – in some cases, under vacuum to prevent it from burning.
The interesting thing here is that, although you buy a product ready to use, in reality that concentrated malt already comes with the minerals and salts that were previously in the manufacturer’s water. That is, the concentration process retains these salts, which are fundamental for the chemical profile of the final beer.
What kind of water should use to make beer with extract?
The good news is that, since the salts are already in the extract, the ideal would be to use very low mineralization water to prepare your beer. What does this mean? Probably distilled water or water with reverse osmosis – both options eliminate virtually any unwanted ion or salt.
If you do not have access to these, it will be best to look for a neutral water, with a minimum content of the six greats: calcium, magnesium, sodium, chloride, sulfate and bicarbonate. This can help you maintain a balance and prevent excess from affecting the flavor or clarification of your beer.
Is it advisable to make water adjustments for specific styles?
For especially lupulate or maltose beers, you may want to experiment with the proportions of chloride and sulfate. But, eye, it is not convenient to overload the water with salts if you are not sure what is in the extract. The key is to understand that salts already in the malt do much of the work in the mineral profile.
If you are making a partial mixture with grain malt, then you should adjust the chemistry of water and pH, as well as artisanal brewers, to obtain the best conversion of sugars and a balanced profile for fermentation.
Final reflection: purity is not just for purists
What can we get from all this? That in the art of making beer at home, having water as clean and neutral possible can greatly simplify the process and reduce variables, especially in extract recipes. The next time you prepare your mixture, ask yourself if the water you are using can be purest. Sometimes, less is, and in the home brewery, that maxim can translate into a cleaner beer, softer and, ultimately, more delicious!
