Fabulous Fun Facts: How Does Water Affect Your Coffee?
Madison Company lives and breathes sensors, so of course we get a kick out of fun facts about sensor applications as well. See if you can guess where a sensor is used after you read this Fantastic Fun Fact! (Pssst…. You’ll find the answer in parentheses below!)
The right way to make coffee is how YOU like it – but there are a few tips to ensure that perfect cup.
The NCA recommends the following:
- Make sure that your tools — from bean grinders and filters to coffee makers— are thoroughly cleaned after each use.
- The quality and flavor of your coffee is not only determined by your favorite brewing process, but also by the type of coffee you select. There can be a world of difference between roasts.
- Fresh-roasted coffee is essential to a quality cup, so buy your coffee in small amounts.
- The size of the grind is hugely important to the taste of your coffee. If your coffee tastes bitter, it may be over-extracted, or ground too fine. On the other hand, if your coffee tastes flat, it may be under-extracted, meaning your grind is too coarse. Brewing methods with longer contact time require a coarser grind (and vice versa – your espresso should be very fine).
- The water you use is very important to the quality of your coffee. Use filtered or bottled water if your tap water is not good or has a strong odor or taste, such as chlorine. If you’re using tap water, let it run a few seconds before filling your coffee pot, and be sure to use cold water. Avoid distilled or softened water.
- Your brewer should maintain a water temperature between 195 to 205 degrees Fahrenheit for optimal extraction. Colder water will result in flat, under-extracted coffee, while water that is too hot will also cause a loss of quality in the taste of the coffee.
- The amount of time that the water is in contact with the coffee grounds is another important flavor factor. In a drip system, the contact time should be approximately 5 minutes. If you are making your coffee using a French Press, the contact time should be 2-4 minutes. Espresso has an especially brief brew time — the coffee is in contact with the water for only 20-30 seconds.
