When it comes to brewing an incredible cup of coffee, two factors make the biggest difference: the beans you choose and the water you brew them with. While most of us obsess over the coffee itself, water often gets overlooked and yet it plays a massive role in how flavours are extracted and expressed in your cup.
The Lotus Coffee Brew Water Kit gives you full control over this variable, allowing you to build custom water recipes that can highlight sweetness, enhance body, or bring out the bright, fruity notes from your coffee.
Use this kit as an education tool to experiment with post extraction mineralising coffee, simply add a drop of each mineral to 4 cups of the same coffee to taste the difference between the minerals.
With this kit, you can follow recipes developed by respected coffee educator Lance Hedrick, replicate the mineral profile of your favourite roaster’s water, or experiment to craft a unique recipe of your own.
The beauty of Lotus is its flexibility, whether you’re chasing clarity, balance, or complexity, you can fine-tune your water to suit the exact style of coffee you love.
What’s Inside the Lotus Minerals Kit?
Each kit comes with four concentrated mineral solutions that form the foundation of your brewing water. Mixing bottles are sold separately, giving you the flexibility to make as much or as little as you need. By combining these ingredients in different ratios, you can transform ordinary distilled or reverse-osmosis water into a powerful brewing tool.
Understanding Minerals in Brew Water
Magnesium & Calcium (Hardness)
These minerals determine the "extraction strength" of your water. Think of them like the gears of flavour: adjusting the hardness can pull more out of the coffee grounds.
-
Calcium tends to boost sweetness while preserving clarity, making delicate coffees feel balanced and clean.
-
Magnesium adds depth, complexity, and mouthfeel, rounding out the cup with a more textured body.
Finding the right balance between the two is key — too little and your coffee may taste thin or under-extracted; too much and you risk muddled or harsh flavours.
Potassium Bicarbonate & Sodium Bicarbonate (Alkalinity)
These minerals act as buffers that control how acidity presents in your cup. They don’t just mute or enhance flavours — they shape the overall experience of brightness and balance.
-
Sodium smooths out the cup, softening bitterness and lending a rounded sweetness. It’s especially helpful when brewing darker roasts or more aggressively extracted coffees.
-
Potassium encourages fruity, high-tone flavours to pop, bringing out liveliness in bright, floral, or fruit-forward beans.
Why Use Lotus Water?
By manipulating the mineral balance of your water, you can experience the same coffee in completely different ways. One recipe might bring out syrupy chocolate sweetness, while another highlights citrusy acidity or floral aromatics. Instead of being locked into your tap water’s fixed mineral profile, the Lotus Kit hands you the keys to adjust and explore, giving you the freedom to brew coffee exactly the way you like it.
For the curious home brewer or the professional barista, this kit is a game changer. It unlocks a deeper level of control, helping you discover new dimensions in coffees you thought you already knew.
