Best way to experience new coffee

“We were fed up buying bad coffee beans from the supermarket and didn't have time to go to the farmers markets too often. Having new coffee beans delivered has been amazing. We haven't liked every bag we've got, but we have found some amazing ones, and it all adds to the enjoyment of sampling new styles we would normally never have known existed.”

Roast: Mixed
Flavours: Variety of flavours

How PCX works

Get this one, or compare a few

Start with a single coffee, or line up a few side by side in a tasting box. Going big? The Discovery Box goes up to ten as a one-off or subscription.

Find what you love

Some people enjoy variety box after box. Others notice which bag empties first and stick with it. Either way, you're drinking excellent coffee every day.

Put it on repeat

Found a favourite, or love the surprise? Subscribe and it just turns up.

“While we love trying new coffees each time, it's good to have a favourite to come back to.”

Espresso starting point

Dialled in on a Breville Barista Express

Dose: 16.5g of fresh grounds in the basket
Yield: 36-38g of espresso in the cup
Time: 28 to 32 seconds, timed from the first drop
Grind: Fine, like caster sugar. Bitter and slow? Go a touch coarser. Sour and fast? A touch finer.

Tip: Start here. Not quite right? Change one thing — usually the grind — and tomorrow's cup is better. Today's is still fresh coffee.

“Amazed how smooth this coffee is when still brewing it at 'max beans' setting for my 1L jug percolated coffee machine. No shortage of flavour and no milk required as no bitter tinge comes through over the course of the whole pot.”

“I’ve just tried the Perfect Pair: Dark Roast Duo from Perth Coffee Exchange and I’m genuinely impressed. Both roasts are full-bodied, smooth, and packed with flavour without any bitterness. Campfire Whispers has a rich, smoky depth that’s perfect for my morning brew, while Grand Central is bold and balanced—great as a long black or through the espresso machine.

“This is my morning starter, this coffee is what the label says, chocolatey, intense aroma. Tastes so good, I have espresso shot with a little water & one sugar. I take the Aeropress to work with pre ground coffee so I can have the same great coffee all day!”

Questions about mystery bags

Which option suits my machine?

Tell us your brew method at the picker and whatever's inside will be ground to suit. Pick Wholebeans if you've got a grinder. The mystery is the coffee, not whether you can brew it.

Does my grind choice apply to whatever's inside?

Yes. Your grind choice applies to whatever coffee you receive.

How fresh is the coffee?

Our roasters roast fresh for us in small batches, and we usually dispatch within 1 to 2 business days. Coffee actually improves for the first week or so after roasting, then holds well sealed. The roast date is on the bag.

What if I don't like it?

Tell us what didn't work and we'll help you find something closer to your taste. Full policy in our help centre.
