What water is used for Guinness?

Answered by Willian Lymon

Guinness is a famous Irish stout that has been enjoyed by beer lovers around the world for over two centuries. One question that often arises is what water is used in the brewing process of Guinness. As an expert on the topic, I can provide a detailed answer.

Contrary to popular belief, Guinness is not made with water from the River Liffey, which flows through Dublin. The St James’s Gate Brewery, where Guinness is brewed, is indeed located on the banks of the River Liffey in the heart of Dublin. However, the water used in the brewing process does not come from this iconic river.

Instead, the water used in the production of Guinness comes from the Wicklow mountains, which are situated a little way to the south of Dublin. The Wicklow mountains are known for their pristine and pure water sources, making them an excellent choice for brewing Guinness.

The decision to source water from the Wicklow mountains is not a recent development. In fact, Guinness has been using this water source for many years, ensuring consistency in the quality and taste of their famous stout. The water is carefully selected and treated to meet the specific requirements of the brewing process.

Using water from the Wicklow mountains has its advantages. The water is naturally filtered through the granite rocks of the mountains, which helps remove impurities and provides a clean base for brewing. This natural filtration process contributes to the unique character and flavor of Guinness.

It is worth noting that water plays a crucial role in the brewing process, and different water sources can have a significant impact on the final product. Guinness has recognized the importance of using high-quality water, and the selection of the water from the Wicklow mountains is a testament to their commitment to producing a top-notch stout.
