After many years of using

After many years of using filtered water, various bottled waters, I finally decided to control the mineral content of my water and bought both the Espresso and Classic Third Wave Water packets. I am using them in my espresso machine and for my Pour Overs and AeroPress. Depending on the bean/roast I sometimes dilute the packets to 1/2 strength depending on the amount of extraction power I want. I have been very happy with them. I feel like the frequent struggle with getting a sour leaning cup has large gone away and it is one less variable to deal with. I simply add it to a gallon of distilled water and have not found it to be much more than the bottled waters I was previously buying. One more step in the right direction on my coffee journey to the perfect cup!

Convenient, Easy to use!

I have very soft water so I probably don't need the packets but did not know if it would be ok in my Espresso machine until I received it. I do recommend them based on ease of use. Just buy a gallon of distilled and drop one packet in. Seems relatively economical as well.

Make sure you order the

Make sure you order the correct formula. I ordered the wrong one and discovered later it was not suited to espresso machines. I get my starting water from the RO filtered water machine at the grocery store.

Mixing 1 gallon of distilled

Mixing 1 gallon of distilled water with a packet of Clive makes for much better tasting coffee. Our son likes to drop in, fill up his commuter cup with my coffee and enjoy too!

Awesome! We love TWW and are happy you can taste the difference.

I enjoy using the 3rd

I enjoy using the 3rd wave packets. I can tell a difference in water quality, and my kettles do not scale up as fast as using bottle water.

To be candid, I have

To be candid, I have no way to evaluate this product. I accept your advice not to use hard water because of mineral deposits in boiler/heating coil or distilled water because of taste and because demineralized water might be too strong a solvent and cause materials problems. So, I use reverse osmosis water and add back the desired minerals level/composition via Third Wave. My expresso machine is only a year old, so I wouldn’t expect to see any effects yet. I plan to continue to use Third Wave on basis of some combination of logic and faith and hope I never find out whether it works or not.
