    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.

    Calcium is the preferred source of hardness for light roasts and great at accentuating the fruit notes in coffee while maintaining a high degree of clarity. Calcium is an ingredient in Lotus Water recipes as well as many roaster water recommendations.

Fair price for a refill

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


I've been really impressed with Lotus Water over the past couple of months I've been using them. My go-to recipe is the Rao/Perger recipe from the site. It's worth noting that these drops have a circular tip, which Lotus Water seem to have adjusted their recipes for only recently. The Calcium dropper is a little more finicky than the others, and I'd recommend holding it at 30-45 degrees when adding it to your water, to avoid large droplets.


Lotus water makes my coffee much tastier and the price is very approachable - compared to other alternatives
