Scale is the white lime-scale left behind from temporary hardness (and other negative chemical reactions) while corrosion is the process that begins breaking down the metal in your espresso machine boiler. We followed the standard SCA cupping protocol, minus their water quality standards, which is our usual method for evaluating coffees. Additionally, depending on where you live, the hardness or softness of your tap water could be impacting the taste of your coffee.

Your city will always have some amount of minerals in your potable water supply and they are not the right minerals for brewing coffee. Because the idea of Third Wave Water is to build a great water for coffee extraction from scratch, we used it as a control for our experiments. We manufacture sticks of all-natural minerals that when mixed with distilled water (or reverse osmosis water, Zero Water filter, etc), it creates optimized water for brewing coffee. The anti-hard water camp believes that the added minerals muddy up the taste of the coffee, leaving a finished product that tastes bitterer than it should. We are proud to share the official press release and white paper with three case studies that explore that challenges of water for cupping at origin and coffee education.The Peak Water Pitcher’s technology is specially designed to make perfect water for coffee, no matter your tap water’s starting point.
