Hey There ☕🌿

If you’re like me and love a good iced coffee but want something different, this Rosemary Brown Sugar Cold Brew is a total game changer.

The combo of deep, caramel-like brown sugar and fresh rosemary? It’s smooth, earthy, and just sweet enough.

I first tried this when I had leftover rosemary from dinner and thought, “What if I threw this in my coffee syrup?” One sip later and I’ve been hooked ever since.

It’s surprisingly simple, but feels fancy.

You’ll love this if you want a café-style drink at home—without fancy equipment or a barista badge.

Why This Recipe Works (Quick Science!)

The rosemary infuses into the syrup because herbs release their oils when heated in liquid. Brown sugar adds depth thanks to molasses, which gives a richer, more rounded sweetness than white sugar. The cold brew keeps the acidity low, so everything blends super smoothly.

Common Mistakes

  • Boiling the rosemary too long – This makes it bitter. Simmer gently, then remove the sprigs.
  • Overdoing the rosemary – Just 2 sprigs is perfect. More can overpower the drink.
  • Using weak cold brew – You want it strong so it doesn’t get lost with the syrup and ice.
  • Not straining the syrup – You’ll want a smooth, herb-free syrup for best texture.

What to Serve With

  • Almond biscotti
  • Banana bread
  • Yogurt and granola bowl
  • Avocado toast

FAQ

Can I use regular brewed coffee instead of cold brew?
Yes! Just make sure it’s cooled completely before mixing.

Can I use dried rosemary?
Fresh is best, but you can use 1 tsp dried rosemary. Just strain well and use half the steep time.

Can I make the syrup ahead?
Totally! It keeps in the fridge for up to 2 weeks.
