Third Wave Water Minerals - Medium Roast Profile

Medium Roast Profile was created for those looking for a rounder, smoother cup of coffee with a natural sweetness. This mineral solution adjusts the composition of the water to favor medium roast extraction, revealing caramelized notes, a velvety body and a more harmonious taste.
