The coffee-to-water ratio is a critical factor in brewing a perfect cup of coffee. It affects the strength, flavor, and overall experience of your coffee. Here's why it matters:

  • Using the correct ratio ensures that you get a consistent flavor every time you brew.
  • The ratio determines how strong or weak your coffee will be. Adjusting the ratio allows you to customize the strength to your preference.
  • Proper ratios help in balancing the extraction of flavors, ensuring your coffee is neither too bitter nor too weak.
  • Using the right amount of coffee and water prevents wastage of both, making your brewing process more efficient and economical.
