You do not need expensive equipment to enjoy a better cup of coffee. A French press, pour-over dripper, or AeroPress can all produce excellent results.
Start with fresh water and recently ground beans. Measure your coffee so the taste stays consistent. Brewing time matters too: too short and the cup can taste sour, too long and it may become bitter.
Try different methods until you find the one that fits your routine. Some people prefer the clean taste of pour-over, while others enjoy the fuller body of French press.
