Fountain Seltzer

Fountain seltzer, also known as soda water or sparkling water, is a type of carbonated water that is often found in restaurants in the United States. It is called "fountain" seltzer because it is often dispensed from a soda fountain, which is a machine that mixes and dispenses carbonated water and flavored syrups to create a variety of carbonated beverages.

Seltzer is simply water that has been infused with carbon dioxide gas under pressure, giving it a distinctive fizzy or bubbly texture. It is often used as a mixer for cocktails or as a refreshing alternative to sugary sodas. Some people also enjoy drinking seltzer on its own, either plain or flavored with natural fruit essences or extracts.

If you are interested in trying fountain seltzer at a restaurant, you can simply ask the server or bartender for a glass of seltzer water. You can also ask if they have any flavored seltzers available. Some common flavors include lemon, lime, orange, and cherry.

It's worth noting that fountain seltzer is different from club soda and tonic water, which are also types of carbonated water. Club soda is similar to seltzer but often has added minerals for flavor, while tonic water has a bitter taste due to the addition of quinine. Both club soda and tonic water are often used as mixers for cocktails.
