Bagpu55 - Im on the same boat as you. However, unless you have it side by side, you’ll find very hard to be able to tell the difference. Saying that, I remember when I started using the distiller (I went from Ashbeck to Distilled water) and I immediately noticed that my coffee was very “bright”. And then I remember speaking to Dave about it, and he said that our tastebuds get used to new tastes very easily. And he was right.
However, try this:
- Brew a Moka Pot, or Aeropress, or whatever else that’s not espresso with the water you use in your espresso machine;
- Use Volvic, or Tesco Ashbeck, or Waitrose Essentials (Lockhills?) (stuff that people put into their machines) and then try something different, like Evian.
It’s a very good way of asserting what difference water makes when brewing.
