Warnings Do not use hot water in the coffee maker. The machine will heat it for you. Be careful not to grind the beans too fine or it will clog the filter and back up the coffee machine.
Do not let the brewed coffee sit for too long. Coffee becomes increasingly bitter the longer you let it sit. Half an hour is pretty much the longest you should let it go without drinking it. Additionally, coffee maintains freshness better in an insulated carafe than a glass carafe on a warming plate
You can reheat your cold coffee in the microwave without it becoming bitter. If you've sweetened your coffee with sugar, the sugar may caramelize a bit, but then again, you might prefer that flavor!
Coffee stains can be hard to remove from clothing, car seats and many other surfaces.
Always remember to turn off the coffee pot when you are done drinking. While rare, electrical fires can happen, particularly if your coffee maker doesn't have an automatic shut-off feature.
Contrary to popular belief, you should not store beans in the freezer. It both damages the flavor of the coffee and causes condensation on the beans when they are removed from the freezer, exposing them to moisture. Store coffee in an airtight glass container at room temperature away from direct sunlight. Storage in the freezer should only be done for extended storage if no readily available source of good coffee exists nearby. Divide coffee into one week portions and remove from the freezer the day before you plan to use.
Using permanent mesh filters and French presses, while they can produce a better tasting product, can cause an increase in LDL cholesterol and have been linked to higher rates of heart disease as there is no paper to absorb the chemicals in the beans.
