Stay away from coffee beans that are flavored and packaged. These beans are sprayed with flavored oils that are very difficult to clean from coffee grinders and coffee makers. While it may seem as if the coffee machine has been cleaned well, the beans layer over time in the machine and will cause any coffee to taste off. Use fresh flavors instead, like cinnamon and vanilla. Bottles syrups also work. If you cannot drink the pot full pot of coffee, freeze the remaining coffee into ice trays. These cubes can be a great way to create fabulous and strong iced coffee. Coffee ice cubes can be put into hot coffee to cool it down, or even used in specialty drinks. There is no need to dispose of coffee that has not been drank. Do not, however, reheat it. What you should do is store it in your refrigerator inside of a plastic container. You can then use it anytime you feel like having iced coffee.
For a stronger cup of coffee, you might want to try using a French press. French presses get more flavorful coffee because the squeeze out extra oil from the coffee beans. If you use a regular coffee pot, the oil might soak into the filter. You have a variety of options to select when you are making coffee. Some people like more mild flavors; others like a full dark roast. Some like flavored coffees, and some coffees are quite sweet. Drinking flavored coffee is not as popular as simply adding a flavored creamer to regular coffee.
