The Last Blast
THE LAST BLAST from Roemer Overdiep on Vimeo . Stephen Sweeney built us a Transparent PortaFilter and the first two video clips we made were eye openers for many coffee aficionados. Still, there is more to clarify by using Sweeney’s TPF. For instance, we would like to check if a less tightly fitting tamper would ensure the puck remains in place when the piston is raised on a lever machine. This weekend we set out to film more, starting off with the Rocket E61 machine. The calm trickle of water above the puck was a bit of a surprise to us, as it demonstrates how on such a machine the pre-infusion and pressure buildup is very gentle and gradual. Alas, the TPF burst after 1.5 shots so that was all the footage we were able to record for now. Hopefully we will be able to do the rest later this year. Again, we thank Stephen Sweeney for providing us with his TPF!
