Weigh the coffee going in. Weigh the coffee coming out. It might sound a little ridiculous, but I do this every time I make coffee including with the ROK espresso maker. As a result, I make better coffee more consistently.

“It’s almost as bad as asparagus”
As the weather warms up here in Australia, cold brew coffee comes back on to the radar. There’s a number of ways to enjoy cold coffee and making it is super-easy. You can make cold brew with a simple low-tech set-up like a glass jar, or hack your Aeropress or invest in some of the more advanced systems we cover below.
Cold Brew or Cold Drip
Cold Brew – coffee and water are mixed at the start of the process and can be steeped for up to 15 hours. The grounds are then filtered out. Depending on the coffee to water ratio used, you can make either a ready-to-drink brew or a strong coffee concentrate for mixing with milk (or whatever takes your fancy).
Cold Drip – The water is added (dripped) on to the coffee very slowly – anywhere between 2 to 6 hours depending on the flow rate. The already filtered cold brew drips out the bottom into a jug. Cold drip is generally brewed as a concentrate for mixing.
Talk about going the extra mile! Our mate Andrew from Pulse Digital sent this video of him making a custom handle for his ROK portafilter. The portafilter is beautiful and the video is slick. I’m blown away!
The spout of a regular portafilter sure makes it look like your espresso is coming out in a nice neat stream, doesn’t it? It gives you the impression that everything inside the basket is as it should be. How nice. Isn’t coffee wonderful and easy? La la la.
Once you take the bottom off your portafilter you may discover that it’s an absolute shambles in there. Coffee may shoot every which way and land anywhere but in your cup. I’m sorry to report it’s not the naked portafilter that’s letting you down – you have some homework to do.
They’re built to last, but it doesn’t mean you can’t give them some love. It’s super easy to maintain or repair your ROK, Presso & Aeropress. We have the parts and advice you need to get the most out of your gear. Check out our Refurb kits – you can easily do it yourself, but if you need any help, give us a shout.

This is a demonstration of what an espresso shot from a ROK, looks like when your coffee is ground too coarse. Coarse coffee creates less of a barrier to the water and so doesn’t allow you to build enough pressure for good extraction. The water flows too fast and the resulting coffee will lack crema and taste weak / bitter. Continue reading
