Coffee do's and Don'ts
Making great coffee at home doesn't require expensive equipment or years of training—but it does require attention to a few key principles. Whether you're brewing your first cup or refining your technique, these do's and don'ts will help you get the most from your beans.
The Do's
Do start with fresh beans. Coffee is at its peak flavor within two to four weeks of the roast date. Check the bag for a roast date, and buy from roasters who prioritize freshness. Stale beans will taste flat and dull, no matter how perfect your technique is.
Do grind just before brewing. Whole beans stay fresh longer than ground coffee. Once ground, coffee begins to oxidize and lose its aromatic compounds within minutes. Invest in a burr grinder—it produces a more consistent particle size than blade grinders, which matters for extraction.
Do use the right water temperature. Aim for water between 195°F and 205°F. Water that's too hot over-extracts and tastes bitter; water that's too cool under-extracts and tastes sour. If you don't have a thermometer, let boiling water cool for about 30 seconds before pouring.
Do measure your coffee and water. A basic kitchen scale takes the guesswork out of brewing. A common starting ratio is 1:16 (one part coffee to sixteen parts water by weight), but you can adjust based on your taste preference.
Do clean your equipment regularly. Oils and residue build up on grinders, filters, and brewing vessels. Clean your grinder weekly, rinse your filter basket after each brew, and deep-clean your coffee maker monthly. This prevents rancid flavors from tainting fresh coffee.
The Don'ts
Don't store coffee in the freezer or refrigerator. Moisture and temperature fluctuations degrade coffee quality. Keep beans in an airtight container at room temperature, away from direct sunlight and heat sources. A pantry or cupboard is ideal.
Don't use pre-ground coffee if you can avoid it. It oxidizes quickly and loses flavor fast. If convenience is essential, buy smaller quantities and use them within a week or two.
Don't reuse old grounds. Once coffee has been brewed, the extraction is complete. Reusing grounds produces weak, unpleasant coffee and wastes your beans.
Don't ignore your water quality. Tap water with high chlorine content or mineral buildup affects taste. If your tap
