The water quality thing changed how I brew now
I always thought it was just snobs being picky about water for coffee. Then I tested my tap water here in Phoenix with one of those TDS meters last week and it was at 380 ppm, which is apparently really high. Most of the good coffee shops aim for like 150 ppm or something. I read this article from some specialty coffee site that said over 60% of bad tasting home brew is actually from the water chemistry being off, not the beans or the grinder. That blew my mind because I've been blaming my old grinder for months when the water was the real issue. Now I'm buying jugs of filtered water from the store and honestly the coffee tastes cleaner, less bitter. Has anyone else actually tested their water and seen a big difference?
