Dependent on your raspberry syrup (homemade is best) you'll either have a beautifully fruity and refreshing drink, or one that's a tad on the sweet side...
I made this drink as posted with the mindset that it was going to be too sweet and I would have to adjust it later. It really was not. The lemon juice balances the 2 syrups (both homemade) nicely and it has a great raspberry finish.
