Many people are passionate about their coffee.
Many of us simply want a pleasant jolt of caffeine.
Both groups are vexed when we purchase a cup of coffee that is extremely bitter. What causes that?
Coffee that is too finely ground for the brewing process is often bitter. The wash of hot water first extracts caffeine and flavor. Then it extracts tannins that make the coffee excessively bitter.
The coffee maker often does not have much control over the process. Somebody else purchases the coffee and the 'grind' is whatever it is. Management is unlikely to appreciate us peons tinkering with the guts of the coffee maker. What is a coffee lover to do?
Mrs ERJ's wisdom
Mrs ERJ was reminiscing of the days when she was kitchen help at a summer camp.
Ever one to step-up and do more than her share, she awoke early one morning and made coffee for the crew.
She remembers, with chagrin, that the coffee was horrible. It was pale and weak.
In an effort to make the coffee percolate more quickly she had filled the urn with hot water. The urn perked until the thermostat in the base sensed the brew was hot enough.
The take-home lesson is that the starting temperature of the water is a key variable in how extractive the common coffee urn will be. The coffee maker might not have control over the grind of the coffee or the thermostat in the base of the urn but they can control the temperature of the water at the start of the process. Try using slightly warmer water if your perc-ed coffee is too bitter.
