CoyoteOldMan I do make pour overs regularly but use the mineralised RO. I find it fine. I did find a massive difference in tea with / without hard water. The tea from mineralised RO is lighter and taste a lot better. I always found the tea with hard water even with a drop of milk was harsher in taste.
Agree, easier to descale the kettle. I will defer it until/if she comes back. The risk of she asking for a hand grinder for pour overs will be more than the water filter! I think I should better look for an electric grinder for myself before my hand grinder disappears! Anyway, that’s another thread. 😂
