For many years I futzed with roasting/grinding beans, and spent big
bucks on so called 'rare' beans plus mucho money on fancy shmancy
grinders and brewers... all for naught.
It's not possible to brew good coffee without good water... a few
years ago I installed a Reverse Osmosis water filter... what a
difference good water makes. Now I buy ground coffee in big cans for
cheap (Walmart Brand), makes fantastic brew, but it's really about the
H2O.... if you're using tap water you're masturbating. Bottled water
is tap water too, only from someone else's tap, probably from a garden
hose. And all those paper/charcoal element filters attached at the
sink spigot are no better than aquarium filters... will load up with
bacteria/viruses and make you very sick.
If you're a coffee and/or tea drinker you need an RO filter.
