Glacial

My use case has been ultra light to light roast espresso shots 1:2.5 ratio at 93C on high extraction burrs. I really like how it has given a smooth finish bright acidity and I have had less astringency when I push extractions. I like the creative profiles I can get with lotus but right now I really like empirical water and plan to stick with it for a while.

5 Month Use Review

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.

The Verdict Is In

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.

Makes a big difference

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!

They say winter is coming but for me it’s Spring all year long.

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.

Terrific!

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!

Excellent water

Had a chance to try both water types of empirical water and thoroughly enjoyed each - more so than the mineral packets available.

If you’re skeptical, it’s worth the try!

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!
