I like my skeeterpee sweeter then the recipe calls for. I used 2 cups of sugar for 1 gallon or 400g of sugar. The recipe calls for 6 cups for 5 gallons or 233g per gallon soooo if using concentrate look at the grams of sugar on the back and add accordingly. also keep in mind sugar helps take away the tartness so if using a concentrate with a lot of acid in it it will take some sugar too to cut the acidity in the skeeterpee.
