Water Filtration Options for Coffee
What water filtration option is best for coffee?
The best option is water that tastes clean, has moderate minerals for extraction, and will not scale your equipment quickly. Many homes can use filtered tap water, but hard water may need softened, blended, or remineralized water for espresso machines.
What to Check First
Test hardness before choosing a filter.
Avoid pure distilled water unless you remineralize it.
Protect espresso machines from scale first, then fine-tune taste.
