How many cups of coffee do you drink a day? Clark says his wife's day doesn't get going until she has her coffee. Clark's executive producer Christa is up to about two cups a day, while Joel -- his producer -- enjoys one cup of coffee after dinner per day. They all brew their java at home. If you're a coffee lover, you might be seeing some headlines that may scare you. Brazil -- the dominant producer of arabica beans -- is facing a drought that promises to raise the price of coffee, according to a recent report in Barron's. But the impact on those who drink at home will probably be minimal because it's so inexpensive to begin with. Instead of being four cents per cup at home, it might be six or eight cents. However, many people enjoy their coffee outside of the home at an expensive shop. So the message here is brew your beverage at home! Clark's wife converted to drinking coffee at home when she got a fancy automated electronic brewing center. Her cost is about 23 cents per cup, but there's no mess or fuss and it saves them a bundle instead of going to Starbucks.
