Gather all ingredients and wash the fresh strawberries thoroughly. Slice them into small pieces to release their natural juices.

Fill a tall glass about three-quarters full with ice cubes.

Pour 1 tablespoon of acai juice concentrate into the glass. Adjust amount based on preferred strength.

Add the sliced fresh strawberries to the glass and gently press a few berries against the ice using a spoon to release flavor.

Pour in 1/4 cup white grape juice for natural sweetness and balance.

Squeeze 1/2 tablespoon of fresh lemon juice into the mixture.

Top the glass with 3/4 cup of water or sparkling water, depending on your preference for still or fizzy.

Add 1 tablespoon of agave or simple syrup if you prefer a sweeter drink.

Stir well to combine all ingredients thoroughly and distribute the acai juice evenly throughout the drink.

Optionally garnish with fresh mint leaves and a strawberry slice on the rim for a café-style presentation.

Serve immediately and enjoy your homemade Starbucks Strawberry Acai Refresher copycat drink.
