Constraints are where the best drinks are born.

When we headed to MICE (Melbourne International Coffee Expo), the brief was simple: create a signature drink using our seasonal Peachy Keen blend, serve it fast and make it something people actually talk about. Oh, and we expected to pour between 200 and 300 of them in three hours.

No pressure.

If you've ever worked at a busy coffee bar, you already know the challenge. Speed matters. Simplicity matters. But a signature drink still has to earn its name. It has to be special.

That's where the Peach Fizz came in.

Start with the coffee. Always.

The best signature drinks don't hide the coffee. They elevate it.

Peachy Keen already had a story worth telling. We built the blend from three coffees: a rich, chocolatey Papua New Guinea, a sweet co-fermented Colombian (fermented with actual peaches, yes really) and a honey-processed Colombian that adds a gorgeous creamy texture. The result is a cup bursting with juicy stone-fruit character.

So the drink didn't need to do much. It just needed to lift what was already there.

Quality tonic water brings brightness and a slight saline bitterness from the quinine. Elderflower cordial adds a floral sweetness that plays beautifully with all that peach. Together, they make something refreshing, layered and just a little bit unexpected.

P&R Peachy Keen blend

We served it on a classic Melbourne autumn day. Cold, wet, grey. It was a hit anyway.

Simple ingredients. Easy build. Genuinely delicious.

You'll need:

  • Ice

  • 4g elderflower cordial

  • 80g quality tonic water (check it contains real quinine)

  • 1 single espresso of Peachy Keen

Here's how:

1. Fill a lowball rock glass with ice

2. Add the elderflower cordial

3. Pour in the tonic water

4. Slowly top with your espresso shot to keep the layers

5. Serve as is, then encourage a stir to bring it all together

That's it. Everything you need is at your local supermarket. Just buy the best tonic and cordial you can find. Better ingredients give the coffee more room to shine.

Why this matters for cafes

A great signature drink does two things: it excites customers and it doesn't slow your team down.

The Peach Fizz is quick to teach, easy to scale and tied to a specific seasonal story. It's a limited blend, a summer-into-autumn serve and that's exactly what makes it feel premium. It's not just a drink. It's a reason to come in.

And because Peachy Keen won't be around forever, there's a natural urgency to it. Seasonal coffees create a creative window. Use it.

And yes, this is just as easy to make at home. Grab a bag of Peachy Keen, a bottle of tonic and you're most of the way there.

More to come

This is the first in our Peachy Keen signature drinks series. We've got more seasonal serves coming, each one built around the blend, each one practical enough for both cafe bars and home setups.

In the meantime, grab a bag of Peachy Keen and give the Peach Fizz a go. Or share the recipe with your team as a starting point for your next seasonal special.

The best signature drinks don't need to be complicated. They just need to be memorable.
