I used sauvignon blanc for my base. Due to time constraints and frankly, the fact that I was feeling lazy, I couldn't find peach vodka. Therefore, I went with passion fruit vodka.

Next time, I might go with some mango too, especially if I am using the passion fruit vodka.
I tripled the recipe, but didn't add quite as much sugar (I used two cups, rather than the two and a quarter cups.) Next time, I would go even lighter on the sugar.
