Household batteries (the usual suspects: AA, AAA, C, D, 9-volt) can be recycled through battery retailers like Batteries Plus. While you save up enough old batteries to make it worth a disposal trip, keep your dead batteries in a dry place that's out of reach of kids.
Water temperature is vital. Doing it correctly, you can make what many say is the perfect cup of coffee. Ideally, you want the temperature between 195 and 200 degrees F. One way to do this is to boil the water and use an âinstant readâ thermometer from any kitchen store.
Light roasts also retain most of the caffeine from the coffee bean. Light roasted beans generally reach an internal temperature of 180Â°C â 205Â°C (356Â°F â 401Â°F). At or around 205Â°C, the beans pop or crack and expand in size. This is known as the âfirst crackâ (for the âsecond crack,â see below).
