The two variables that have the biggest impact on your coffee are the coffee beans themselves and the water you use to brew them. Lotus Water allows you to craft water that can increase the desirable flavors in your coffee and mute the undesirable ones. Each kit comes with four ingredients; Magnesium, Calcium, Sodium, Potassium.
The Lotus Coffee Brew Water Kit utilizes a system of concentrated mineral water and droppers to allow users to quickly and easily create water recipes or experiment with how different minerals can change our perception of the flavors present in coffee.
