    The flavour of your water has a direct impact on the flavour of your coffee. The flavour of water is determined by the minerals and other matter present. The content of your tap water largely depends on where you live and how the water was treated. If you live near an ocean your water may have a slight sulfur smell due to the presence of sulfur producing microbes. Water taken from lakes can taste earthy from leftover plant matter and so on. The key takeaway is that any off flavours in your water before you brew your coffee are still going to be there when you're finished making it. Starting with distilled or reverse osmosis water is the best way to ensure you are starting with a clean slate when brewing coffee.

    Potassium bicarbonate is used to add alkalinity to water which serves as a buffer to acidity. Potassium Bicarbonate is an ingredient in Lotus Water recipes as well as many roaster water recommendations.

Worth a try

A convenient and effective tool to dial in water recipes. Good for both building a water profile or dose single brews.

Fair price for a great tool

Being able to buy each bottle separate is really nice if you find a recipe you enjoy.

Expensive but worth it

Whether the tap water in your area is ideal or not, it's nice to have that extra bit of control over your brews. In a blind test between Lotus Water and tap water, the tap water brew seemed sour and flat by comparison. Personally, I prefer the results I'm getting with Lotus over Third Wave Water, but it is a pretty big cost up-front.
