What does brown sugar simple syrup taste like?
While simple syrup made with white sugar is great for adding sweetness, simple syrup made with brown sugar is great for adding sweetness AND flavor. That flavor comes from the molasses in brown sugar.
That said, the difference between light and dark brown sugar is the amount of molasses in it. The amount of molasses in brown sugar also impacts the depth in flavor. Dark brown sugar (which has more molasses) results in a deeper more caramel-toffee-like flavor. Light brown sugar will give you a more subtle caramel taste.

🌟Recipe Tips
You can use either light or dark brown sugar, but for a deeper, more toffee-life flavor, you’ll want to use dark brown sugar. The extra molasses makes a big difference.
Make it even sweeter by adding 1 to 2 tablespoons of molasses to the saucepan with the water and brown sugar.
For the best tasting brown sugar syrup, use filtered water.
To prevent spilling hot liquid, be sure to let the syrup cool for at least 10 minutes before funneling the syrup into containers.
The container you use (whether it be a glass jar, plastic bottle, etc.) should be sanitized first to prevent bacterial growth.
