Combine raspberries, sugar, and water in a medium saucepan; cook mixture over medium-high heat until sugar dissolves. Bring mixture to a boil; reduce heat, and simmer 5 minutes.
Remove mixture from heat, and let cool.
Pour raspberry mixture into a 1-gallon jar.
Add brandy, and stir well. Cover mixture tightly, and store in a dark place at room temperature at least 2 weeks. Shake jar gently once daily.
Pour mixture through a wire-mesh strainer lined with 2 layers of cheesecloth into jars, discarding raspberries. Cover tightly. Store at room temperature.
