In your kitchen, you have an entire shelf or kitchen counter that contain some or all of the following: burr grinder, scale, timer, kettle and thermometer. Each utensil is vital to your coffee-making process. Burr grinders are a favorite among coffee snobs because this type of grinder compared to blade grinders give you a well uniform size ground and more control over the grind than you do with a blade. What about a scale? Coffee drinkers use a scale because most coffee brew guides use the 1:17 ratio. Without having a scale to weigh out the perfect amounts, you’re missing out on a well-balanced cup. Too much water and too little coffee will result in over-extraction. Your coffee will be bitter, you won’t drink it, and then you’ll fall asleep at work.For example, when using a Chemex for your pour over, a timer allows you to let the coffee sit until your timer reads 45 seconds. This step is called coffee blooming. Hot water forces the coffee to release trapped gases, leading to expansion of the coffee bed, bubbling at the surface, and wonderful aromas are released for you to enjoy.A thermometer allows you to better control and maintain your ideal brewing temperature. The ideal temperature to brew coffee is actually lower than the temperature water boils at, which is 212 degrees (100 degrees C).
