Start simple. Pour a glass of water. Smell it. Does it smell like a damp basement? That’s usually just harmless sulfur bacteria (aka, swamp farts in liquid form).
Now, swish it around your mouth like fancy wine. Don’t swallow. Notice any metallic tang? That could be iron or copper lurking in your pipes. Or it’s just your weird taste buds.
Fun fact: Your tap water has more minerals than your gym buddy’s protein shake. That chalky taste? That’s calcium and magnesium. Not dangerous, but definitely a vibe killer for coffee.
