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.
The fact is that the change in temperature will cause a 'condensation' of the humidity that is natural in fresh coffee. That 'condensation' will result in the humidity leaving the bean when it congeals, and with it, much of its flavor and freshness. Warm is not good for coffee, but room temperature is fine.
