Hi, thanks for the video! im considering buying the robot and im trying to figure out what my workflow would potentially be when it comes to preheating (i like light roast coffee). Would this way of preheating impact the final result in any negative way - based of on the water color it seems that the coffee was getting wet during preheating so just wondering whether that affects brewing in any way? Also, would it be possible to place this on the robot so that the piston gets preheated too?
Hi! Thanks for watching the video. For this method, I place a paper over the coffee bed in the portafilter to minimize any interaction with the hot water, which helps prevent early extraction. During grinding, some coffee particles can stick around the portafilter, causing the water to look a bit cloudy, but using the paper prevents the coffee from mixing with the water used for preheating. While there may be a slight contact between the water and coffee, it doesn’t significantly impact the taste or disturb the coffee’s structure. To heat the piston, you could try placing a cup of hot water underneath the piston instead of the portafilter, or use a 3D-printed tool like Thundies. I showed how I use Thundies to preheat the piston in previous videos. Especially with light roast beans, preheating the piston can have a positive effect on the espresso’s taste, resulting in a more balanced outcome. I’d recommend preheating when working with light roast beans.
I just ordered a robot today.
