Not with their end product - the powder itself is excellent. But every little packet is plastic, and doesn’t have to be. The world has such a serious problem with plastics, and for a lot of products it’s kind of necessary, but this is not one of them.
Restaurants have had the same size single serving packets for sugar, salt, and pepper for decades now and those are paper, which is much more environmentally friendly. It’s even better for usability! With paper, I don’t need to go find my scissors like I do for TWW’s plastic packets.
I asked TWW if they would consider using paper instead, but got a generic reply that they’ll bring it up, but evidently nothing has been done about this.
Is anyone else as disappointed as I am with their use of plastic packets? I care a lot about having clean water for my coffee, and I care just as much about not polluting the rest of the world because of it.
Getting it exactly the same would be hard, getting it close enough is not that hard. There isnt some magic ingredients in third wave to massively improve solubility, just Magnesium Sulfate, Calcium Citrate, and Sodium Chloride in classic for example. Any decent hand mixer (or electric milk frother) ran for a minute or two is going to spread the ingredients around plenty.
I would recommend getting some testing strips to compare a DIY vs. the ready done packets to at least confirm the alkalinity and pH is a close match, then go by taste for the Epsom salts starting from the baseline from an existing guide. Just scale the recipe for the size you want to make, you do not have to stick to a gallon, its also not a magical prerequisite for making it.
Its not for everyone as Third Wave sure is convenient but it is significantly cheaper if you use a lot of 3rd wave.
