There can be a substantial difference in the flavor of coffee based on the composition of the water used to brew it. Softer water doesn't necessarily mean better or worse tasting coffee. Just different tasting coffee. Hardness of the water impacts extraction yield from the coffee. Alkalinity will have a huge impact on the acidity, or "sour" notes in the coffee and you can adjust this to taste.
