How empirical water was Created
In our 7 years of testing, we found that mineral waters from glaciers and springs interact most beautifully with coffee.
To reverse-engineer these natural mineral waters, we painstakingly emulate nature's process for dissolving limestone, i.e. calcium carbonate.
This yields record-low levels of chloride and sulfate impurities in the water, which is what makes empirical water so forgiving to brew with.
Then, we spent several hundred hours fine-tuning these mineral profiles specifically for brewing coffee (& tea).

Customer Reviews
Glacial 1.5 yields an impressively balanced presentation across a wide spectrum of coffees and teas; ultralights, comfort roasts, shaded greens, yancha, puer, and more.
If you've dabbled in making your own brewing water, you'll notice a level of liveliness, clarity, and flavor separation that you might not have expected was possible at this level of texture, sweetness, and depth.
Extra silica is a nice add-on but not strictly necessary imo. It adds a fullish and slippery texture, with an almost-undetectable increase in sweetness.
Most coffees can be pushed a bit harder without becoming muddy or harsh, though careful dialing-in is still necessary for best results.
Empirical Water Glacial version has quite substantially improved my coffee water. I have tried virtually every competitor out there. And I prefer the final product that this water produces. Hardcore baristas and hobbyist alike will enjoy their coffee more.
I was skeptical, initially, thinking that my RO water (which tastes great to drink) was also great for tea. But I was wrong; Empirical Water makes a huge difference to the quality of my tea! Give it a try!
I guess I always spent so much time stressing over coffee gear and technique and didn’t realize a majority of the cup is water. This plays a huge role in the overall taste. I tried cupping with four different kinds of water and both the Spring and Glacial profiles came out on top. Spring on the top for me. Do yourself a favor and get a sample, cup it with what you use now and see the difference.
The water delivered great and really sweet cups. I shall be ordering again!
I received the free sample of spring and glacial water from Empirical water in a Reddit giveaway. I absolutely loved what this water did to my coffee brew using V60 pour over. Ill definitely be buying more in the future!
Had a chance to try both water types of empirical water and thoroughly enjoyed each - more so than the mineral packets available.
Excellent water for coffee, highly recommend!
Overall, the water did enhance the flavor profile of the coffee I was brewing. I was having trouble highlighting the lavender notes, but switching to the glacier water helped in resolving!
After struggling to find good water for tea, I eventually tried Arby's empirical water and I couldn't go back! This gives my tea a much clearer and better taste than any combination of filters or tap water I've tried, without the hassle of having to constantly buy large quantities of bottled water. It's such a simple way to make such a large difference, I'm delighted that this exists!
