Tea & Coffee 02/04 - Temperature Probes and the Advancement of Coffee Roasting (#)

  „Exhaust probes are placed somewhere in the exhaust stream most usually before the blower, but not always. Bean probes are mounted so as to allow the external temperature of the coffee to be measured throughout the entire roasting process. Environment probes are most often used with computerized and automated roasting profile systems, exhaust probes are most often used with overtemperature safety systems, and bean probes are the most widely used and discussed of all the probe positions and are often used in conjunction with environment probes in automated profiling systems. Although they sound like different probes, all three can in fact be the same type of probe hardware; it is the positioning of the probes on the roaster that lend to their respective names: environment, exhaust or bean.“

:: Roast ::

  „Depending on the bean, its origin and the effect you want to achieve, roasting typically takes place between 190 and 220°C - for 10-18 minutes. Does this make it sound like roasting is some sort of exact science? Well it's not. We like to think of it as more of a black art - which is why each and every batch has to produce a real, live cup of coffee for testing by one of our real, live experts.“

CoffeeKid - The Nescafe Beginnings

  „After seeing a demonstration at the Bay, I bought myself a Bodum press pot and I started buying beans at the local IGA and at a local coffee bean roasting place. Drinking Bodum coffee was quite an eye opener for me - coffee could be good in the home! I quickly built up a ritual around the Bodum press pot with my friends, and the "afternoon coffee" became a daily thing to look forward to.“

How to make great coffee

  „Whole beans will begin to lose freshness 21 days after roasting. As with ground coffee, freshness of whole bean coffee can be substantially extended if vacuum packed, to avoid exposure to oxygen.“
