Our first order and very happy with the blend. Very smooth and when we increased the amount we added, it was stronger but still easy drinking. Found a winner and going back for more.

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 market of roasters too often. Having new coffee beans delivered every month has been amazing, we haven’t liked every bag we’ve got but have found some me amazing ones, it all adds to the enjoyment of sampling new styles we would have normally never even knew existed. Have recommended to all my coffee loving friends.

Best so far

We have purchased a few sample packs and almost all of them have been a hit. This one in particular was a beautiful blend and will definitely purchase again. We have a delonghi coffee machine and purchase the whole beans.

Great for latte, cappuccino, flat white, ...

Its cocoa notes work very well with milk type of coffees. Cocoa notes apart, it is a balanced blend. Given it is medium roast, you might need to grind it a bit finer than other beans.

Thanks for your review, G Alquezar !

We're thrilled to hear you're enjoying our blend for your latte, cappuccino, and flat white creations. It's wonderful to know the cocoa notes are hitting the spot and blending harmoniously with milk-based coffees. Your insight on the grind size for our medium roast is incredibly valuable, not just to us but to our coffee community as well. It's feedback like yours that helps us all refine our brewing techniques and enhance our coffee experiences.

Thank you for being a part of the Perth Coffee Exchange community. Your taste buds are on an exciting journey, and we're delighted to be a part of it. Keep exploring and happy sipping! ☕️

It's honestly hard for us to pick between Dark Matter and Supernova. We love both Rockefuel blends. Hands down best roaster in Perth
