Why filter your water?
Water makes up 98% of most black coffees. The taste of tap water varies drastically depending on where you’re living - not just from country to country, but also from city to city.
In Ireland, our tap water is typically ‘hard’ water which means that it is alkaline and contains a high number of dissolved calcium and magnesium mineral salts. These extra dissolved mineral salts impact the taste of our coffee, steering it away from the neutral taste that is ideal for brewing.
As water is such a key component in coffee, it’s important to note that your coffee will only ever taste as good as the water you use to brew it. It can literally make or break your brew!
For example, have you ever tried to replicate a cafe’s coffee recipe but haven’t quite managed to get it to taste the same?
The issue could be that you aren’t filtering your water! Most coffee shops use complex filtration systems connected to their water supply and espresso machines to remove excess dissolved mineral salts that impact the taste of their coffee, as well as damage their equipment.
