Amber on 2025-03-24 (5 stars): I've made this so many times now and I love it! I usually make it specifically to make a gallon of watermelon iced tea which is perfect for spring and summer. If you like sweeter ice tea leave it at the 8oz. I tend to actually use somewhere between 5-6oz because I prefer a slightly less sweet tea.
kat on 2024-08-18 (5 stars): I freeze my syrup using an ice cube tray and then take out whatever rations I need. If the sugar content is too high, I dilute with filtered water and that does enough to help them freeze. I like to make summer last as long as possible, and watermelon is part of that <3
Yolanda on 2023-06-15 (5 stars): This is revelatory with champagne on a hot day! Everyone went wild for it & I didn't tell them how easy it was to make. Even the color is refreshing!
Linda Igelmund on 2023-04-08 (5 stars): Can Erythritol or coconut sugar be substituted for the sugar in the watermelon syrup ???
Stacie on 2022-05-24 (5 stars): I made this as part of our beverages for a wedding reception. Not only was it a hit at the vodka bar, it was absolutely wonderful in lemonade!! I will most definitely make it again!!
Tommy on 2022-03-23 (5 stars): So much cheaper than the Torani syrups used by bars, you can buy it online for only about $7 but shipping is no less than $10 so $17+
