Sompetch "Pack" Katisomsakul — 2024 US National Brewer's Cup 3rd place
"I was pleasantly surprised when I first tried empirical water. When I brewed a natural anaerobic coffee with it, the water softened the funky flavors, allowing hidden elements to shine with a clean finish, even as it cooled down. This water is excellent for enhancing the quality of your coffee. I highly recommend using empirical water to bring out the best flavors in coffee, especially in competitions, as I would do for myself."

Silica
Silica
empirical water is the only coffee water on the market to incorporate silica, a mineral that occurs naturally in many of the world's finest mineral waters.
Silica boosts sweetness, mouthfeel, and aftertaste.
Some describe the silica sensation as experiencing the sensory characteristics of your brew in slow motion. Aromatics stick around in your nose, mouth and throat for minutes on end.
If selected, silica will be added to your Hardness concentrate.
Extraction Booster
Extraction Booster
The Extraction Booster is a dropper bottle of mineral concentrate, designed to increase flavor intensity and definition.

1-on-1 Brewing Guidance
When you're accustomed to brewing with the same water for a long time, it can be disorienting to make a switch - especially when the new water is unlike anything else on the market.
That's why as the developer, I'm offering my time to personally assist you in bringing the best out of your coffee or tea with empirical water.
Guidance includes:
- 1-on-1 Brewing Consultations — Your order confirmation includes my personal contact information. From then on, I'll be available 7 days a week to personally help you every step of the way to brew the best coffee or tea you've ever tasted.
- Brew Video Analysis — Record your brew using your phone camera and send it over. I'll analyze your brew, help you figure out what's going wrong, and explain how to fix it.
Official Discord Access
Water is the most impactful brewing variable. So when you keep the water constant between your setup and someone else's, you gain the advantage of having truly consistent and valuable conversations around coffee.
In the Empirical Water Discord, you'll find people who brew similar coffees with similar brewing methods using the same water. There, you can directly copy already-perfected brew recipes with immediate success — for instantly dialed-in brews.
200% Extra Buffer
All orders come with triple the required amount of buffer.
With extra buffer, you can accomplish two things:
- Reduce harshness — Less bitterness and astringency.
- Boost texture — For lusciously thick brews.
Extra buffer generally translates to a better experience with medium and darker roasts.
Customer Reviews
I cannot praise this water enough - it's simply outstanding.
After testing it against a well-known coffee water solution I've been using for some time, Empirical Water, to my taste, was far and away the better product. And, to be clear, it wasn't even close. Within seconds, on the first sip, it was immediately clear that Empirical Water was the winner, and, indeed, entirely in a league of its own. There was simply no comparison. It was astounding.
I think it's incredibly impressive when a product has the potential to revolutionize the way people taste and experience such culturally and socially important beverages consumed by billions, and I feel Empirical Water has the potential to bring a bit more joy, enjoyment, and deliciousness to people's lives. What an amazing opportunity and laudable pursuit. From my own perspective, after trying it out, I feel there's simply no going back to any other water. And that's a great thing.
If you seek to reach another level with your tea and coffee then seek no more! For you have found the secret ingredient! Water is so important in tea and coffee, its not even funny. With empirical water your tea and coffee will be levels ahead of your neighbors cup ofbigelow or folders!
Brewing with empirical water has produced some of the best cups I've made. I had a natural Pacamara that had been difficult to brew really well and switching to using Empirical Water, Glacial with silica, produced a noticeably creamier more full-bodied texture. More pleasant acidity. Bit more clarity. Longer pleasant aftertaste. This water makes all my brews better and even when a brew occasionally doesn't go well, it's still tasty and has wonderful texture thanks to this water. Definitely try it out, and splurge for the silica, it's worth!
I assume this water is good for any roasting style. But it is amazing for very light roasts, aiding and increasing extraction without adding off flavors or muting acidity and other attributes. Overall far superior to my homemade buffer/hardness solutions.
For the coffee crowd (which I know is most of you) - if you go on YouTube and lookup "gongfucha pu'er tea" and spend 2 minutes watching a video, you'll know immediately I am fully able to empathize with you on the level of meticulous, optimized, detail-oriented care that goes into your daily ritual and life's passion. As "water is the mother of tea", I have spent multiple years fiddling with water, mixing my own mineral batches, and even helping Arby test his waters in the development phase as the journey moved forward.
I've known Arby for a good while now, and since the early days, he's been a man I've categorized in the top percentile of friends that I knew for certain would make a huge impact in his life. He has now created the best water I have ever used.
As of partway through 2023, I totally and entirely refuse to drink any of my nice teas without using Empirical Water. If I don't have enough to use for a session, I will have something else and wait. It's that game changing.
If I could single handedly float his entire company, I would. I am a customer for life. If you care at all about the quality of your tea and coffee, you should be too.
I live in Las Vegas which has some of the worst tap water in the US. Since I learned about the importance of water quality, I've been on a mission to find the best tasting brewing water and have tried many of the commercially available options. With Empirical water, my search is over! This water has given me the best tasting and most consistent brews. Super easy to dial in and then it's just set it and forget it. Highly recommend to anyone on the journey for the best morning cup!
This water works so well for my tea sessions - definitely an improvement over most water. I can taste everything in my tea where I couldn't before!
I love the ease with which I can make good water for my coffee.
love the water! i was actually quite blown away with the results. Was able to try 3 different coffees (2 brews for each coffee one using control water and other empircal water). TDS was on average ~0.1 higher for all the brews with empirical and all had noticeable differences in taste i wont note all but top of the list being a more sweet, like insanely sweet. I used 3 coffees that i know very well and honestly did not know these coffees could have as much sweetness as they did with said brews.
I taste tested the spring, glacial, and TWW:classic profiles ~a month ago. I preferred both profiles over TWW for more sweetness and nuanced flavors I obtained from my brew. I have since purchased the spring profile concentrate with Silica, due to preferring that profile because of increased the increased body. I am unfortunately not able to justify using this water everyday due to my budget, but use it when I am not working morning shifts to increase my enjoyment of my 'premium' coffee.
