If I put the grind size very fine (a 3 or 4 on the dial) I'll get less during pre-infusion, but even less during the real extraction and also it'll be sour or whatever; you can't taste the flavour of the coffee. Pre-infusion is the act of saturating the coffee cake with brew water at a low pressure, typically around 1-2 BAR, for a short period of time, usually 8-10 seconds, before ramping to full pressure. Cross-references: Part number Manufacturer 7479946 BEZZERA 0 Closer to 0 means the two variables don’t have a relationship to each other. When pulling shots with a manual machine, I have found pre-infusion to be a necessity, but how long should pre-infusion last? Pre infusion function applies low water pressure at the start of the extraction to gently expand grinds for an even extraction; Water Tank Capacity: 61 ounce 1600 watts thermocoil heating system with integrated stainless steel water coil accurately controls water temperature; Settings: Single or Double Shot Volumetric Control & Manual Over ride. Lately during pre-infusion, a lot of coffee has been coming through before the pressure ramps up, while it's still low and in pre-infusion. One variable that makes the difference on a manual machine is pre-infusion, and more expensive heat pump machines allow for pre-infusion as well. It depends on the espresso, temperature, dose, and so many other factors. While the Pre-Infusion technology keeps the beans wet and in optimal state for extraction, the pump skillfully applies the right amount of pressure. However, the bloom forced coffee to come out from most of the filter insuring the puck was saturated. For TCF, the trend line has an R^2 of 0.69, which means the trendline plotted is pretty decent.

It very well may be that any flavor advantage comes from the fact that the first batch of water to hit the coffee will have a certain amount of temperature pulled by the coffee itself, making it unable to dissolve certain soluble solids at the beginning. Digital Temperature Control (PID) delivers water at the right temperature +/- 2°F, ensuring optimal espresso extraction.
