A Bracha Achrona on a Drink Before a Meal

When wine is drunk during a meal (with hamotzi), it warrants its own bracha rishona but is covered by birkat hamazon. When drinking wine before a meal no bracha achrona is made before the meal. What about other beverages? What if the beverage is consumed before the meal and will be consumed during the meal as well - is a bracha achrona made before the meal?
