Peach Rosemary Whiskey Sour

Updated 11/5/23 —A stash of frozen peaches and a few fresh lemons meant there was peach simple syrup and a peach rosemary whiskey sour in my future. While peach is a lovely flavor, for me, pairing it with rosemary, a savory element, takes the complexity of the sour up a notch.

The best whiskey sours always have a lovely flavor surprise in them. As a simple standard, they are ripe for variations. This great combination of rosemary and peach with a delicious bourbon is a favorite any time of year.

In addition, rosemary, as a perennial bush, is readily available almost all year and many people have a bit growing in their back yards. So clipping a few sprigs of rosemary for the simple syrup and little extra for garnish is all it took.

If you’re a fan of sours, I’ve got 4 other sours in this series for your to explore: Blackberry Sunset Sour, Whiskey Tiki Sour, Blue Mood Whiskey Sour and Ya Basic Whiskey Sour.

Ingredients in this Peach Rosemary Whiskey Sour

It’s so easy to put this cocktail together. Just one additional step – making a peach-rosemary infused simple syrup. You can make it while peaches are in season, but it does just as well with frozen peaches.

I had the following ingredients on hand to make it:

  • whiskey
  • lemons
  • frozen peaches
  • rosemary
  • sugar
  • peach liqueur
  • optional: egg white, bitters

How to Make Peach Rosemary Simple Syrup

To prepare the peach-rosemary simple syrup, I combined a couple of cups of frozen peaches with a little water and a cup of sugar. I let the peaches start to cook, then added a couple of large sprigs of rosemary. Once the peaches start to cook down a bit and simmer, I turned the heat off and let the rosemary steep with the peaches for about 30 minutes. Once cooled, I strained out the peaches and rosemary and put the syrup in the fridge. It will keep for a couple of weeks, longer if you add a smidge of vodka to it.

The Best Whiskey for a Peach Sour

For this sour, use a whiskey that’s not too aggressive – and one that blends well with more subtle flavors. I’ve had success with Woodford, Michter’s and Wilderness Trail, all three with very different flavor profiles, but ones that can blend well with more fruity and lightly aromatic syrups.

I prefer cocktails made with 94 to 100 proof whiskey when I’m constructing a sour because I don’t want to lose the taste of the whiskey in the cocktail. However, if you prefer more subtle cocktails, keep the proof a little lower for this peach-rosemary whiskey sour.

You’ll notice I’m using a dried persimmon as a garnish here. Peaches are not yet in season, so I’m making due with what I have. It adds a lovely pop of color but if you’ve got a peach on hand, please do use that!

Note that this is a rather sweet sour between the peach-rosemary simple syrup and the addition of Giffard’s peach liqueur (which is by far my favorite peach liqueur on the market). It’s pricier than a generic bottle of peach schnapps, but the flavor profile is much more delicate and easier to layer in cocktails. Just a splash of it added to a mimosa with a fresh peach slice is an incredible thing.
