As an expert sommelier and brewer, I can assure you that purified water does indeed contain salt. However, it is important to note that the amount of salt present in purified water is typically very minimal. The purpose of including salts such as magnesium chloride, magnesium sulfate, and calcium chloride in purified water is not to make it salty, but rather to enhance its taste.
When I first entered the world of brewing, I was amazed to discover the importance of water in the brewing process. Water, being the primary ingredient in beer, plays a crucial role in determining the final flavor profile of the brew. Brewers often pay close attention to the mineral content of the water they use, as it can greatly impact the taste of the finished product.
One of the key minerals that brewers look for in water is calcium. Calcium ions help to balance the pH levels during the brewing process, ensuring that the enzymes responsible for converting starches into sugars are working optimally. Additionally, calcium also helps to promote yeast health and fermentation.
Magnesium and sulfate ions are also important in brewing, as they contribute to the overall flavor and mouthfeel of the beer. Magnesium ions can enhance the perception of sweetness, while sulfate ions can add a crispness or dryness to the beer. These ions, when present in the right amounts, can help to create a well-rounded and balanced flavor profile.
In the case of purified water, salts such as magnesium chloride, magnesium sulfate, and calcium chloride are often added in order to mimic the mineral content of natural water sources. While the amount of salt added to purified water is typically low, it is enough to enhance the taste and provide a more appealing drinking experience.
I personally have tasted the difference between purified water with added salts and plain purified water. The addition of salts gives the water a subtle hint of flavor, making it more enjoyable to drink. It's not a salty taste by any means, but rather a slight enhancement that can make a noticeable difference.
To summarize, yes, purified water does contain salts such as magnesium chloride, magnesium sulfate, and calcium chloride. These salts are added in small amounts to enhance the taste and improve the overall drinking experience. While the presence of salts in purified water may not be immediately obvious, they play a crucial role in creating a more appealing and balanced flavor profile.
