A water sommelier is a specialist in water, similar to how a wine sommelier is an expert in wine. Their primary role involves several key functions:

​

Tasting and Analyzing Water: Just like wine sommeliers, water sommeliers taste and analyze different types of water. They assess the taste, mineral content, and pH levels, among other characteristics. This allows them to understand the subtle nuances between different types of water.

Educating and Advising: They educate customers or clients about the different types of water available, their sources, and their unique qualities. This includes explaining the impact of terroir (the environment in which the water is sourced) on the taste and properties of the water.

Pairing Water with Food: Water sommeliers can suggest which type of water might best complement a particular meal, much like wine pairing, enhancing the overall dining experience. They consider factors like the water's minerality and carbonation level to match it with specific dishes.

Curating Water Menus: In upscale restaurants or hotels, water sommeliers may curate water menus, offering a selection of waters from around the world. This can include still, sparkling, and naturally flavored waters.

Quality Control and Sourcing: They may also be involved in sourcing and ensuring the quality of water served in hospitality settings, ensuring that the water not only tastes good but is also of high quality and safe to drink.

Public Speaking and Workshops: Some water sommeliers conduct workshops, public speaking engagements, or write about their expertise, further educating the public about the importance and diversity of water.
