Do Coffee, Tea or Alcohol Dehydrate Me?

While caffeine is technically a diuretic (it increases water excretion from our bodies), you retain most of the water from caffeinated beverages, such as coffee, tea and soft drinks. Alcohol, on the other hand, particularly at high doses, can cause you to excrete more than you consume. One drink, especially of beer, won't do much (it's about 92 percent water), but wine and hard liquor have more of a dehydrating effect because of their high alcohol content.
