Using the right water for coffee was one of the best tips I learned from multiple sources in order to improve coffee at home. I live in a place in Italy with extremely hard water, so I have a cleaning filter installed that still leaves a series of minerals. Water is good to drink but not to brew coffee.
The solution I’m using now is bottled water, which works really well except for the fact that buying and wasting plastic isn’t ideal at all
Is there any way to obtain good quality water without having a ton of plastic in my bin? I mean I could buy mineral pills or something but still I’d need first to get demineralised water somehow, most likely bottled. So I don’t know really
I have an RO, for reasons. It cost less than the cheapest espresso grinder that’s acceptable, but it has ongoing maintenance costs.
Edit - if you want to get nerdy, a permeate pump and/or high inlet pressure (which is largely out of our control) helps with the longevity of the membrane; I get about 2 years on mine and my intake water TDS is 500ppm; I replace around 75ppm outflow which is higher than “normal” but the water is designated safe to drink to begin with. Basically, the greater the delta in pressure between the inlet and outlet, the less waste is produced and the longer the membrane lasts.
Reverse Osmosis for those like me who had to search what RO means.
For the unselfish it means “reciprocating oral”
