Water is 98% of your cup, so using tap water that tastes like a swimming pool is a crime. Use filtered or bottled water—your beans worked hard to grow, they deserve better than chlorine. It’s like serving a fine wine in a paper cup; it works, but it’s a little sad.
The ideal water temperature is around 200°F (93°C), which is just off a rolling boil. If you don’t have a thermometer, boil it, then wait 30 seconds. That’s your coffee sweet spot—hot enough to extract flavor, but not so hot it burns the grounds like a bad sunburn.
Too cold, and you get sour, underdeveloped coffee that makes you pucker. Too hot, and you get bitterness that lingers like an awkward silence. Watch your kettle, not your phone.

The Ratio: A Little Math Won’t Kill You
The golden ratio is 1 to 2 tablespoons of ground coffee per 6 ounces of water. That’s about one heaping scoop per cup, but adjust to your mood—more for a kick, less for a gentle nudge. I once measured with my heart and ended up with a cup so strong I saw sounds. It was terrifying.
Use a kitchen scale if you’re feeling extra. Weighing 15 grams of beans feels nerdy, but it’s the secret to consistency. Trust me, your taste buds will thank you, and your friends will nod politely.
If you forget to measure, just wing it. Coffee police won’t arrest you—probably.
