  • GREAT COFFEE DESERVES GREAT WATER

    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 flavours in your coffee and mute the undesirable ones. Each kit comes with four concentrates; Calcium, Magnesium, Potassium, Sodium and a Mixing Bottle. Using Lotus recipes, you can explore the different flavours of a single coffee by changing the mineral balance of your water.

    Each kit contains enough concentrate to make up to 450 litres (120 gallons) of mineralized water.

    • Includes:
      • Calcium Chloride Concentrate 59ml (2oz)
      • Magnesium Chloride Concentrate 59ml (2oz)
      • Potassium Bicarbonate Concentrate 59ml (2oz)
      • Sodium Bicarbonate Concentrate 59ml (2oz)
      • Lotus Mixing Bottle
    • Each kit contains enough concentrate to make up to 450 litres (120 gallons) of mineralized water.

A cool kit for the aspiring chemist

Coffee is 98% water, yet is a variable that tends to be overlooked in the brewing process, compared to equipment (e.g., grinders, burrs, flat vs. conical drippers, etc.). This kit is a fun and accessible way for people to start playing around with water chemistry without buying minerals in bulk and weighing things out to the milligram. The online recipes are straightforward to follow and easy to scale depending on the volume of water you want (0.45 L, 1 L, or 1 gallon) so you can experiment to your heart's content. Scott Rao even shared how adding minerals *after* brewing can affect taste. Distilled, RO, or ZeroWater would all work fine, as long as you start with 0 TDS.

As for the quality of the materials, the kit is really nice and would make a great gift. The dropper bottles and mixing bottle are both made of out glass that feels sturdy and thick. My only complaint is that the mixing bottle doesn't have a fill line, so you'll still have to measure out 450 mL of water.

The kit isn't cheap, but you're paying for the convenience of having premade concentrates in a compact form, as opposed to having your coffee counter looking even more like a chemistry lab. Although you can buy individual bottles of solution, I wish Lotus sold "refill packs" of solution so you're not accumulating a bunch of dropper bottles.
