When it comes to brewing coffee...
there are a handful of standard variables that all baristas spend their time working within, but one has been relatively untouchable until recently: grinder speed. Over the last few years more and more grinders have hit the market with adjustable speed capabilities. So when I was in the market for a new grinder I knew this was a feature I had to try out for myself. My first attempt was more-or-less useless since the Weber Key had near constant jamming issues on low RPMs with most coffees I attempted to grind, but luckily I was able to snag the Lagom P64 which is more than capable of cutting through beans of all sizes and roasts.
So in this video I aim to figure out what, if any differences are created with the variable of burr speed when brewing filter coffee and espresso. Each style of coffee will be tested at 200, 800, and 1400 RPM. From there I'll run a handful of experiments, collect the data, and then break it all down into some broad takeaways. So if you're curious about grinder speed and if its worth investing in a grinder capable of these kinds of adjustments hit play on the video above and let's brew this!
