About Cassinova
A small roastery and café in Shelley, Western Australia. We started with a secondhand 5kg roaster and a stubborn streak. Seven years on, we still roast every bean ourselves.
Our story
From a garage to a neighbourhood fixture
It has not been a straight line. Here is roughly how we got here.
2019
The garage years
Daniel Mercer buys a secondhand Probat and starts roasting in a rented garage in Shelley. First clients are three local cafés and his mum, who claims her flat whites are "acceptable now".
2021
The café opens
We take over the old Tribute St shopfront. Twelve seats, a big window, and a roaster visible from the counter so people could watch the drum turn.
2023
Subscriptions take off
The bean subscription launches and quietly becomes half our revenue. Offices around Perth start ordering weekly deliveries.
2025
Catering and training
The coffee cart gets its first wedding gig and the barista course fills every Saturday. Turns out people really do want to learn to pour a decent shot.
2026
Today
Same shop, more beans, same obsession with freshness. We still visit origin twice a year and still taste every roast before it ships.

What we believe
est.
2019
Good coffee is mostly about respect
Respect for the farmer who grew it, for the roast profile that lets it taste like itself, and for the person drinking it at 7am before their shift starts.
We do not chase trends or invent drinks with twelve ingredients. We buy good beans, roast them carefully, and pull shots that taste like the bag says they should. If a customer wants something weird, we will probably make it. But the flat white on the menu is the one we are proudest of.
