ABOUT US
From an Idea to Better Coffee Everywhere
Taylor and Charles were both running coffee businesses in Ohio when they realized the same thing: the beans weren't the problem. They built a formula from scratch — years of testing with chemists and coffee pros — until the water was exactly where it needed to be. One stick per gallon. Works with any machine. Made in the USA.

Elevating coffee, recognized nationwide.
Third Wave Water was featured on Shark Tank, where the founders pitched their innovative mineral blends designed to transform water into the perfect base for brewing coffee.
All five Sharks agreed the difference in taste was undeniable — and the brand even secured a deal with Barbara Corcoran during the show.
Today, it continues to help coffee lovers brew better, more consistent cups at home and beyond.

Frequently Asked Questions
Check out the most common questions our customers asked. Still have questions? Check our help center.
What water do I use?
Start with distilled or reverse osmosis (RO) water from any grocery store. Our minerals need a blank canvas to work properly.
What's the difference between profiles?
Each profile has a unique mineral ratio optimized for specific roast levels and brew methods. Classic is for light/medium, Dark for dark roasts, and Espresso for any roast in espresso machines.
What is in Third Wave Water?
Each profile consists of only three minerals:
- Magnesium Sulfate
- Calcium Citrate
- Sodium Chloride
There are no chemicals used! The mineral amounts vary depending on the profile. We are unable to provide the exact amounts of each mineral in each profile to help protect our recipes.
For a more detailed breakdown on each profile, check our help center article here.
Will this cause limescale?
No. Our mineral profiles are completely safe for your equipment.
Not all calcium is "bad" calcium.
Bad Calcium: CaCO3, Calcium Carbonate, is bad calcium. It is formed from the reaction of calcium cations and carbonate ions that are commonly found in many natural waters as well as treated waters. Calcium Carbonate is what causes limescale to form because it is temporary hardness. Its solubility decreases when temperature increases.
When CaCO3 is present in your water in your coffee maker, for example, when the water heats up to brewing temperature, it then precipitates out of solution in the water and adheres to the surface of the container it is in, causing scale because it is not soluble once the water evaporates. Over time, that layer of minerals builds up and can cause overheating, bad tasting coffee, and a decreased lifespan for your equipment.
The Good Stuff: All Third Wave Water minerals, which are permanent hardness, will not cause that same type of scale to build up. Like Calcium Carbonate, when the water evaporates, the mineral residue will be left inside. However, Third Wave Water minerals are still soluble after that evaporation, so any new water introduced will re-dissolve them. This means that there is no need to descale your equipment.
All Third Wave Water profiles contain only permanent hardness. None of our profiles will cause any scale!
One of TWW's founders, Taylor, made a short video to illustrate this difference between temporary and permanent hardness.
Will this protect my espresso machine?
Yes. Our Espresso Profile eliminates corrosive chlorides and prevents limescale buildup, extending the life of your boiler.
Do you have a profile to use with tea?
Yes, the Dark Roast Profile works the same for tea as it does for coffee!
Some tea blogs typically recommend 80 - 150 TDS (total dissolved solids). Our formula is 150 TDS high in magnesium helping provide natural sweetness in the flavor profiles.
Brew times will need to be adjusted when you change waters when brewing tea (or coffee), as this is also true when you change any water type.
We recently did an experiment tasting different tea varieties with all of our mineral profiles, and across the board among our team, the Dark Roast Profile was the preferred winner for all tea types!
