After a few comments that suggested the issue could be that water from the thermocoil needed to be slowed by a coffee puck to maintain temperature, I have some follow up tests performed with espresso in the filter (17 g).
I tested the coffee as it poured from the portafilter: as you can see from the following video, the temperature maxed out around low 130 F.
I also tested the temperature of the coffee in the cup immediately after brewing. The cup was preheated with 195 F water. As you can see from the following video, the temperature in cup immediately after brewing was around 150-155 F.
Finally, I measured the temperature of the puck post brewing. as you can see from the following video, the temperature of the puck was 190-195 F.
I’m not sure whether to be concerned about the temperature here. The puck temperature obviously seems fine – 190-195 F is what I would expect, given the temperature for brewing is supposed to be 195-205 F, correct?
But the temperature of the coffee actually coming out seems low to me. It’s 130 F draining out of the portafilter. While it is 150 F in the cup, that feels low, given that the cup itself was pre-heated with 195 F water. I’m wondering how cold the coffee is, if pouring it into a 195 F warmed cup only brings the temperature of the coffee up to 150 F.
What do you guys think? Is there a problem with the water temperature on my Barista Touch? Am I crazy? Is it fine? Should I return it? What’s going on? All thoughts/help is appreciated.
