Store your freshly ground coffee in the freezer until you need it. It will be fresher. You may also add some flavorings such as chocolate, cinnamon sticks or toasted almonds with the beans before grinding. Use less sugar and make your tea taste different by dissolving old-fashioned lemon drops, or hard mint candy in your tea. Add a pinch of baking soda to your glass or a teaspoon in your gallon pitcher.
Loose tea lasts about a year.
Tea bags last for a shorter amount of time. If you use an old tea bag, it is best to leave it in the hot water for a longer amount of time. Use a wine that you would like to drink. I have a solution for those of us who don't like it when our drinks, like tea, get watered down. For people who don't like drinking water because of its lack of or funny taste, use fruit juice, kool-aid, etc. to make ice cubes instead of water.
