Water in a Beer: Everything you need to know
Water, the most underrated component of beer, makes up for ninety percent of this popular brew. But surprisingly, most people overlook this fact, focusing more on the flavors brought by hops, malt, and yeast.
No matter whether it’s a 12-ounce or 16-ounce beer can, water is the essential backbone of beer, serving as the medium where all the magic happens. It’s also surprising that for every liter of beer, it requires almost 4 times as much water, and the better the water quality, the better the beer tastes.
So paying attention to the water chemistry for making beer goes a long way to making sure you end up with a stupendous tasting beer. Let’s dive into more detail about the mystery behind water content in beer and how it affects the brewing process.
Water usage in the brewing process
On average, brewers use about four liters of water to produce a single liter of beer, which is considerably less than other types of alcohol like whiskey, for example, which takes an astonishing 35 liters of water to produce a tiny 1-liter bottle.
Brewing a top-notch beer takes precise measuring of all ingredients, like the correct amount of brewers yeast and the grain to mash water ratio. It’s all carefully calculated so that we beer drinkers can enjoy a refreshing cold pint in the pubs straight from the tap or at home from a beer can or bottle.
The importance of water in brewing
Brewing is a water-intensive process, and the quality of water plays a significant role in shaping the overall taste, color, and quality of the beer. Learn more about the effects of brewing water.
Water is a vital element used in virtually every stage of the brewing process because it makes up a huge portion of the resulting beer product itself. Beer makers use more water to brew beers than you think, and we cannot overemphasize its significance.
Water plays a role in beer and liquor making, cooling, packaging and cleaning various equipment. Moreover, expert brewers profess that cleaning is more water-intensive as producing a gallon of beer requires about three to five gallons of water for cleaning.
Some less efficient breweries consume more water. Unfortunately, the breweries in drought-struck areas put up with the tension between water supply and demand. For this reason, most breweries develop ways to utilize available water for sustainable brewing. This includes reducing the quantity of water sent down the drain or lost to evaporation.
The water content in different beers
The amount of water will vary depending on the size of the beer you’re drinking and the beer’s alcohol content.
For instance, Captain’s Daughter beer contains 8.5 percent alcohol, a relatively high amount, leaving it with 91.5 percent water. In contrast, the lighter Schaefer Light beer with only 4.4 percent alcohol has more water at 95.6 percent. Thus, the alcohol content can slightly affect the water composition in beers.
When comparing beer sizes with an average ABV of 5 percent, the bigger the beer can, the more water it contains. If we set 95% as the percentage of water the end result is there being 11.4 oz of water in a 12 oz beer. (12 oz x .95 = 11.4 oz) The other 5% is alcohol which would be 0.6 oz of alcohol. (12 oz x 0.5 = 0.6 oz). Let’s take a closer look:
| Can size | Alcohol content | Water content |
|---|---|---|
| 12-ounce beer can | 0.6-ounce | 11.4 ounces |
| 14-ounce beer can | 0.7-ounce | 13.3 ounces |
| 16-ounce beer can | 0.8-ounce | 15.2 ounces |
| 20-ounce beer can | 1 ounce | 19 ounces |
