BWT Espresso Water Filters - Canada's Specialty Coffee Source

Water is the most overlooked variable in home espresso. It makes up over 90% of your cup, and if it's too hard, it scales up your boiler, destroys your heating element, and shortens your machine's life. If it's too soft, it extracts flat, dull coffee with no complexity.

BWT engineers water filtration specifically for espresso and coffee equipment. Their patented Magnesium Technology doesn't just remove scale-forming calcium — it replaces it with magnesium, which is proven to enhance extraction and sweetness. The result is water that's better for your machine and better in your cup.
