When brewing coffee in hard water conditions, the challenge lies in balancing the minerals present in the water to achieve the perfect balance of flavors. Hard water, rich in minerals like calcium and magnesium, can affect the taste of your coffee, sometimes making it bitter or dull. This guide will explore the best brewing equipment designed specifically to handle hard water, ensuring your coffee tastes as rich and flavorful as it should.
Overview & Background
Hard water is a common issue for many coffee enthusiasts. The presence of minerals can interfere with the extraction process, leading to a less-than-optimal taste.
