I was going to order the samples, but $5 shipping for a $10 order was a bit too much.

When I order, I plan to buy multiple packs at the same $5.00 shipping charge.

According to my quick calculations when a vial of powder is mixed with a gallon of distilled water Third Wave Water yields:

• 29 mg/l of magnesium
• 119 mg/l of sulfate
• 142 mg/l of water (a component of Epsom salt)
• 19 mg/l of calcium
• 60 mg/l of citrate
• 11 mg/l of sodium
• 16 mg/l of chloride

Mostly it looks fine for brewing, but I think I'd have reservations using this in an espresso machine. Not so much for scale based on the hardness, but because of the high amounts of sulfate and the inclusion of chloride. Both compounds can corrode metals. Chloride is particularly tough on stainless steel and some espresso machine manufacturers caution against it (La Marzocco) and others (Synesso) even say to avoid it completely.

Thanks for sharing!!

Hi Taylor,

Before ordering, is it safe to use it in espresso machines ?

Thanks

Jo

You mean I can stop using this. Thanks for sharing. To expensive to ship here but I like the concept.

I'll give you a little background on myself. I have owned a roaster for 8 years where we are a distributer for Nuova Simonelli. I am a memeber of the Roasters Guild, Barista Guild and newly founded Coffee Technicians Guild. I have rebuilt plenty of espresso machines and batch brewers. Here is a Nuova Semi-Volumetric I rebuilt http://imgur.com/a/nPZqv. While developing TWW, machine maintenance was always a concern. I know there are others "GCWater" who use calcium chloride and none of the espresso machine manufactures like it.

All that to say, I am currently working with both Slayer and La Marzocco (Modbar) to verify they are okay with it being used on their equipment. Their techs got bulk samples last month to play around with. I never like to say "Trust Me" if I don't have to but I feel qualified to say that TWW is safe for espresso machines. I will hopefully have something more official from those companies in the near future. If you are still uncomfortable with using it then I recommend holding off until their blessing.

Thanks again for the questions, I hope I wasn't too forward.

I'm starting to wonder when someone will offer Third Wave Electricty and Third Wave Air...

A roaster I know had to get their warehouse rewired to the mains at their own cost as their connection didn't deliver what one would expect...maybe there's something to this

Third Phase Electricity
