Seltzer water is carbonated water, made by adding carbon dioxide under pressure. The main feature of Seltzer water is the presence of sodium salts which give it a distinct quality and taste. Seltzer water is often added to alcoholic drinks to dilute them. Now you may even find flavored drinks made by adding Seltzer water. Seltzer water is considered healthier than carbonated soft drinks. If you have a Seltzer siphon you can even make Seltzer water at home.
Joseph Priestly invented Seltzer water in 1767. He infused water with carbon dioxide by suspending a bowl of water above a beer vat at a local brewery. He offered it to his friends as a special refreshing drink. Seltzer water over the years has been referred to as club Seltzer, sparkling water, seltzer water, etc.
With a few differences in these Seltzer water variants, it is basically carbon dioxide pumped into regular water which makes them bubbly. These drinks usually do not have any alcohol in them. They are often mixed for cocktails which gives them a degree of fizz. When mixed with alcoholic drinks it gives it dilutes and mitigates the harsh effects of alcoholic drinks.
When Seltzer water is made the carbon dioxide and water form carbonic acid. Alkaline salts like sodium bicarbonate (baking Seltzer) are added to it to reduce the acidity. These salts give the drinks a nice taste as well as neutralize their acidic flavors. Commercially Seltzer water is made by chilling plain water to 8 degree Celsius. Sodium or potassium based compounds are added to reduce acidity. Carbonation process follows which is adding pressurized carbon dioxide to water. It dissolves in water and top-off fill is added.
At home you can make your own Seltzer water using a Seltzer siphon. It can be made by a readily available 1.1 US qt rechargeable Seltzer siphon. There is a disposable one-shot screw-in carbon dioxide cartridge as well.
It is extremely easy to make. Just chill filtered tap water in refrigerator, then add one quarter or one half teaspoon of baking Seltzer to the siphon. Pour chilled water and add carbon dioxide. Seltzer water thus made may not have as much fizz as commercial ones available; it nearly has the effect if you chill water before carbonation.
Seltzer water is a safer option to other carbonated drinks. Most drinks contain sweeteners which may lead to diabetes. Similarly they often have caffeine which may cause problems like indigestion and leaching of minerals from your body. However, Seltzer water does not contain excess sweeteners.
They mostly have sodium salts which are rather useful in keeping the body hydrated. Moreover, it helps you to get relief from indigestion and acid reflux. The only people, who may have to be careful, are those with higher levels of sodium in the body.
Before you use it just make sure to consult your doctor so that you are assured of its benefits and not suffer from any complications. Seltzer water has no carbohydrates. Just add a flavor of your choice to make an innovative yet healthy drink.
