Use filtered or distilled water
No matter your brew method, coffee is 99% water so the quality of your H20 makes a big difference. Even if your tap water tastes like mountain dew (not Mountain Dew), it's going to taint the flavor of the coffee. Luckily, that water cooler where you theoretically talk about last night's Big Bang Theory is filtered, and can do wonders even for your office coffee-maker.
