October Ale

2 cups ginger beer or ginger ale
1 cup grape juice
1 teaspoon sugar (omit if using ginger ale)

Combine all ingredients and serve chilled.  In the novels the characters 
refer to October Ale as a beer that's brewed and takes several months to 
ferment.  The recipe book is aimed at children and they came up with a 
non-alcoholic drink for the name.  I found it refreshing, my wife thought it
tasted weird.  If I make it again, I'll re-name it to something more 
appropriate, October Fizz perhaps.
