What are the different types of ice and how do they affect the taste of beverages?

There are two main types of ice: regular ice and gourmet ice. Regular ice is made from tap water and can sometimes have impurities that affect the taste of beverages. Gourmet ice is made from purified water and is often denser and slower melting, which can enhance the flavor of drinks. The type of ice used can impact the overall taste and quality of a beverage.
