Purified through boiling and condensation, this specific type of water, devoid of minerals, impurities, and dissolved solids, is frequently used in espresso machines. Employing this purified water in such machines is a common practice among coffee enthusiasts seeking to optimize their brewing process.
The absence of minerals reduces scale buildup within the machine’s intricate components, prolonging its lifespan and reducing maintenance needs. This lack of dissolved solids also allows for a cleaner extraction of coffee flavors, resulting in a purer, more nuanced espresso. Historically, the increasing complexity and cost of espresso machines spurred interest in preventative measures against scale, leading to the adoption of this specialized water source.
