Very good both products Dark and regular. We like to change from one to the other and now and then. Sometimes even go back to tap water to taste what we don't miss.
Makes a noticeable difference in the taste of my coffee. I like the folders dark roast (black silk) but only when I use the 3rd wave water for dark roast. Otherwise my coffee doesn't taste very good.
Gives coffee a vibrant taste.
Very pleasantly surprised in the difference of the taste of the coffee
I recently switched over to the Dark Roast Profile from the Original. The difference is definitely noticeable. The body of the coffee seems more full and the mellow notes come through much better than with the original. That said, Original also improves overall taste compared to standard tap water. I'm a fan of the Dark Roast - REQUEST to @thirdwavewater - Please Make this available in the 5-Gallon size as well.
