"People often ask me for advice on brewing water, and the most common question is “what’s the first thing I should do?” A great brewer, like a great chef, understands how the ingredients will affect the brewing process and its results. The first step to understanding the effect of water on brewing a great beer is to know what is in it. The Brewlab® Basic and Brewlab® Plus from the LaMotte Company are economical, easy-to-use test kits to quickly measure the mineral content of water and allow the brewer to make informed decisions in the brewing process. Great beer starts with a knowledgeable brewer."

Better Chemistry... Better Beer!
Alkalinity is generally a problem in brewing water. Alkalinity is the carbonate and bicarbonate content of the water, and acts to raise the pH of the mash and beer. Water hardness can offset the alkalinity, and for that reason both parameters are typically measured as “Calcium Carbonate” in order to determine the net effect.
The chloride ion acts to bring out the sweetness and fullness of the malt flavor, much like table salt does for food. Craft brewers often add calcium chloride to brewing water for Pilsner and other lagers.
Water hardness is a brewer’s friend because calcium and magnesium are important ions in many biochemical reactions during mashing and fermentation.
Calcium: Helps prevent enzymes from denaturing and extends their activity in the mash, promoting clarity, flavor, and stability in the finished beer.
Magnesium: In small amounts Mg is an important yeast nutrient. The better the “yeast ferment”, the cleaner the alcohol produced.
The chemistry of brewing and cooking is complex, and while knowing the mineral content of the water is a critical first step to predicting the impact of the water to the beer, the best way is to measure it, and that is where pH comes into the picture. The mineral content of the water directly affects the pH of the mash, and the pH of the mash affects the entire brewing process—both in process performance and beer flavor. In order to consistently brew great beer, the pH of the mash, wort, and beer should be monitored at every step.
Sodium acts in concert with chloride to enhance the sweetness and fullness of the malt, but just as in food and cooking, too much can oversalt the beer and result in salty or metallic flavors. Sodium is ubiquitous in water supplies and mineral additions, so it is important for the brewer to know how much the water has before any treatments are planned. Sodium can be easily determined by calculation from the results of the other tests.
Sulfate and chloride ions in water affect the flavor balance of the beer, from hoppy to malty. The sulfate ion acts to accentuate the hoppiness and dryness of the beer, making it more crisp tasting. Craft brewers often add calcium sulfate to their brewing water for pale ales and IPAs.

If you want to use any of the on-line brew calculators out there, (one such calculator is www.brewersfriend.com/water-chemistry which is referenced on the back page of the BrewLab® manual) you may find that they are set up by chemical symbols or they ask for test results that don’t correlate directly to the tests in the BrewLab® kit. Here are some definitions and conversions that may help:
Ca+2 = Calcium (In the BrewLab® kit this is expressed as CaCO3, see conversion below)
Mg+2 = Magnesium (the BrewLab® kit this is expressed as CaCO3, see conversion below)
SO4-2 = Sulfate
Na+ = Sodium
Cl- = Chloride
HCO3- = Bicarbonate (This is the primary contributor to alkalinity, in the BrewLab® kit it is expressed as Calcium Carbonate (CaCO3) so a conversion is needed for HCO3, see below)
Fe = Iron (No test for this is included in the BrewLab® kit)
To convert the total calcium result from your BrewLab® result into calcium (expressed as CaCO3 ppm) you will need to multiply the result by 10 or 20, depending on sample volume used. Then to convert the result into calcium (expressed as Ca+2 ) you will need to multiply the result by 0.4
To convert the magnesium result from your BrewLab® result into magnesium (expressed as Mg+2) you will need to multiply the result by 10 or 20, depending on sample volume used.
To convert the alkalinity result from your BrewLab® result into bicarbonate (expressed as HCO3) you will need to multiply the result by 10 or 25, depending on sample volume used.
To convert the Chloride result from your BrewLab® result as ppm you will need to multiply the result by 10 or 25, depending on sample volume used.
