Decent Espresso Shot Visualizer is amazing
It started humbly enough.
To use it, you would upload the .shot file from your Android tablet running the de1app, and you're good. Next, Johanna wrote a de1app plugin that automatically uploaded your shots for you, making Decent Espresso Shot Visualizer hugely easier to use. Once you have a login, everything is just automatic.
Decent baristas are constantly talking about their profiles, asking "how can I improve my espresso?", "what profile will work best for this bean?" and "I think I found a way to improve xyz...", and so Miha's Decent Espresso Shot Visualizer site became the standard way everyone talks about espresso in the Decent world.
Miha didn't stop there. He's added truly useful features, such as comparing historical shots to each other. You can also download the exact profile to make any historical shot, that anyone has made, to your machine, try to recreate it and then compare your effort to the person who you copied from .
As the community tried to make sense of various "puck integrity" calculation methods, Miha implemented the 3 different lines that were being put forward, so each could be seen in context, used and discussed. There is puck resistance vs conductance, and also the derivative of conductance (which helps loudly show you transient defects in the puck, such as quick channels that heal). Each chart line type is easily enabled/disabled, so you don't have "noisy charts" with data you don't care about.
Because it's all cloud based, each improvement is immediately available to all espresso shots on the site.
A huge number of Decent users now are on the site, and he's made it easy to follow others. This makes it easy, for instance, to immediately try out a recipe that some Decent Luminary has just invented.
The charts, and overall user interface, are quite tasteful, being not just pretty. They use good design principles to cleanly "display quantitative information" in a way that is conducive to insight.
As Decent Espresso Shot Visualizer is also an open source project, others have contributed features.
Recently, Louis-Philippe Huberdeau added a tasteful "call out" on the charts, showing the "current shot weight" (in cup) at transition points This is hugely helpful for profiles with long, held preinfusions (Londonium, Blooming, Adaptive) because the amount of dripping during the preinfusion hold is the easiest way to "dial in" you grind. Blooming Espresso, for instance, tastes best with about 8g of dripping, whereas Adaptive works well with 2g to 4g of dripping, before the pressure rise.
Miha has found Decent Espresso Shot Visualizer to be so successful that he can't afford to host it for free, and has started to transition it into a business. That's good news, as money sent his way will help him continue to improve the service. It's too important, now, to rely on his altruism.
You can use Decent Espresso Shot Visualizer in its free tier, where it saves a month of your shots. Upgrade to €5/month, and you now have an unlimited history.
Most interestingly, he has a commercial (café) tier, with ideas in progress for helping cafes manage a fleet of Decent espresso machines, across several locations. As consistency across staff and locations is the #1 hardest problem for most cafes, I think his approach has great merit, and for a cafe, the €30/month fee would be inconsequential compared to the benefits. I had a bunch of ideas for an "café nanny" product, but I've handed those all over to him, as I think he's in a better position to implement them than I am.
To use visualizer.coffee in your de1app, go to settings->app->extensions and enable it. Create a free account at Decent Espresso Shot Visualizer and then enter your name/password into the extension. I highly recommend everyone give it a try, it's just so useful.
