Coffee Mad - Session 1

It is useful to have the following equpment on hand:
1. A commercial or prosumer espresso machine.
2. A commercial or prosumer espresso grinder
3. A tamper sized properly to form a good seal with your portafilter baskets
4. A botomless or naked portafilter

5. Scace Thermifilter, a timer, a thermometer, and a gram scale


The Scace 2 Thermofilter gives you both temperature and pressure readings directly at the group. This is where we are most interested in receiving data, and now you can do both. The device is very capable of measuring temperature to within a 10th of a degree. The "T" type thermocouple is very fast and accurate when used in conjunction with a Fluke digital thermometer. - See more at: http://www.espressoparts.com/scace-2-espresso-machine-thermofilter-temperature-pressure-device#sthash.ExF70a0P.dpuf


Note:
Pressure is the other fluctuating factor when we discuss stability in an espresso machine. Knowing your brew pressure is just as important as the temperature, and we have found that coffee can taste quite different at variable pressures.

The standard of a shot of espresso:
1. Brewing Ratio: 6.5 - 20 g grounds to 3/4 - 1 1/2 oz (21-42ml) water
2. Extraction pressure: 8-9 bar = equal = 116 - 130 psi
3. Extraction time: 20 - 35 seconds
4. Temperature: 185*F - 204*F = equal = 85*C - 95.5*C
