Herkimer's newly modified Synesso.

In the lab at Herkimer Coffee in Seattle's Phinney Ridge neighborhood something exciting is happening. Using a timer, regulated line pressure and a pump bypass valve, a Synesso Cyncra has been modified for pre infusion brewing with variable pressure.
In stage one, the timer provides 4 seconds of 5 bar, regulated line pressure. The timer is easily adjusted, this was just a starting point. When the timer runs out, the pump receives full power but a bypass valve diverts a portion of the flow to the drain. Using about 7 bar, the bypass phase then leads to stage two.
Stage two is full pump pressure, approximately 8.5 bar. Based on visual cues the Barista goes back to bypass after just a few seconds.
The result was viscus, sweet, espresso with a huge amount fat to coat the mouth. Pure deliciousness.
For love of coffee
